Winix Air Purifiers 2016 Research-Based Review:Facts Not Fluff

Winix U300 Air PurifierAre you confused about Winix Air Purifiers?

Series names no longer in use. The mind-blowing number of models.

How to know the difference between the models? Or to know which environment they suit? Let alone decide what’s best for you?

No need to look any further. I’ve done the research. Spent the 20 plus hours sorting it out.

I’ll tell you if they’re any good. If they produce ozone. Where they’re made. How noisy they are. Which one to choose. And lot’s more.

What are the different models?

There are five different types in the Winix range.

I have given them my own series names to help with your understanding. (And added other marketing references where applicable).

Click the links below to access the model details and decide which is best for you.

  • The 5000 series – 5300 and 5500, and newer versions named 5300–2 and 5500–2. All four models are available for sale. Marketed in the past as the PlasmaWave series (with a prefix of WAC and did include a WAC6300).
  • The P series – P150, P300, and P450. Called the FresHome Series.
  • The B Series? – The B151 model is a recent release. It has a four-stage filtering system but has similar specifications to the P150.
  • The HR series – HR950 and HR1000. Marketed as part of the PlasmaWave Series.
  • The 9000 Series – There is just one current model with this numbering. It’s the 9500 sometimes known as the Pet Machine. A WAC9300 was also sold with the series called the Ultimate Pet Series but is no longer available.
  • The U Series – U300 and U450. Also marketed as the Signature Series.

The 5000 (PlasmaWave) and P (FresHome) series are best to look at together. They use a similar three-stage filtering system. Both the 5300–2 and 5500–2 have four levels of filtration with an extra pre-filter. The P series is a later version with some extra features and an updated look to the exterior design.

The HR (PlasmaWave) series use a five-stage filtering system. As a unique feature, the HR1000 integrates Wi-Fi to provide remote control capabilities.

The U (Signature) series is the newer version of the 9000 (Ultimate Pet) Series. Both series have a 5-stage filtering system. The U series released later has a striking cleaner and modern styling.

What’s the difference between the filtering systems?

For a long time, Winix had two filtering systems across their range of models.

The first type being the 3-stage version installed in the 5000 (PlasmaWave) and P (FresHome) Series. In general terms, this type has Odor-Absorbing Carbon, 99.97% effective Washable True HEPA, and WINIX PlasmaWave® Technology.

And the second type is a 5-stage version that comes in the HR, U, and 9000 Series. The stages include a Washable Pre-Filter, CleanCel® Technology, 99.97% True HEPA Filter, Advanced Odor Control Washable Carbon Filter, and WINIX PlasmaWave® Technology.

Recently by way of the new B151 model they introduced a four-stage filtration system. The stages in this model are Activated Carbon Pre-Filter, 99.97%, True HEPA Filter, Cleancel Antimicrobial Finish, and WINIX PlasmaWave® Technology.

And you could argue the new 5300–2 and 5500–2 also have a four-stage filtration system with the inclusion of the permanent pre-filter.

So what do each of the different stages of the filtering system do? Why is it important to you?

Each of the different filters plays a vital role in producing the clean air that contributes to your better health.

Washable Pre-Filter
* The first line of protection.
* It traps larger particles like pet hair, dander, and dust.
* Can help to extend the life of the following stage filters.

Odor-Absorbing Carbon & Advanced Odor Control Washable Carbon Filter.
* Negates chemicals and odors.
* Resulting air doesn’t smell and is cleaner.

99.97% effective Washable True HEPA / 99.97% True HEPA Filter
* Tested to meet the standard of removing 99.97% of particles that are 0.3 microns in size and higher.
* Captures allergy and asthma causing particles.

CleanCel® Technology Finish
* Covers the True HEPA filter.
* Prevents the growth of mold and bacteria.

WINIX PlasmaWave® Technology
* Always the last filter action.
* Attacks the molecules of odors, viruses, gasses, or chemicals remaining at the end of the filtration process.

The WINIX PlasmaWave® Technology is installed in every model. It is a key differentiator against other air purifiers in the market and needs to be looked at further.

Back to Table of Contents

What is WINIX PlasmaWave® Technology?

It is a relatively new electric oxidizing system using plasma ionizers. Developed by Mitsubishi and Sharp Electronics. Winix adopted the technology and created it’s unique version called PlasmaWave.

Explaining how plasma technology works gets technical and requires more than a few words.

If you skipped the technicals, that’s ok. But be aware of the concerns about the impact of the technology on your health.

Which after all is why you’re looking at an air purifier in the first place.

The concerns relate to whether ozone is produced by PlasmaWave in enough quantity to harm you.

Ozone is an oxidant. Long-term exposure to it increases the risk of death from respiratory illness. An air purifier operating at extremely high voltages can create ozone.

But the PlasmaWave operates at low voltages. It uses the corona discharge method in its operation and produces some ozone. It’s hard to know how much. Presumably, it comes under EPA recommendation levels. Otherwise, we’d have a lawsuit in the works, and I’ve not heard of any.

It does produce oxidants known as “hydroxyls” that eliminate pollutants. Unlike ozone which takes a long time to decay, Winix plasma-ions don’t last long and disappear as soon as the power is off.

If this leaves you concerned about ozone or oxidant levels, the best approach is to follow what reviewers have said they do. Turn the PlasmaWave on only when the room is empty. When you want to clean the air before occupying the room.

This approach may also help address the noise that occurs when the PlasmaWave is operating.

How noisy is the Winix?

Like air purifier reviews of all manufacturers, Winix users say the noise of any of the models is noticeable when being run at the highest fan speed. They do comment favorably on the lack of operating noise at the lower speeds.

What is different, though, (and even the user manual contains a warning) is that when the PlasmaWave is running there is the possibility of a squeaky or humming type of sound. Users have said that it’s not noticeable at the highest fan speed, and that’s when the PlasmaWave is most likely to be running.

Some users found this disconcerting, to the point they returned the unit. But the PlasmaWave is not required to be run continuously and as I said earlier some users have talked about having it on, only while they are out of the room.

Also, it’s important to note there is an Auto mode of operation which adjusts speeds according to the signal sent by a smart sensor. If there’s no increase in pollution, then it will adjust back to lower speeds and quiet running. It’s a great feature to have and not just as it impacts noise.

Back to Table of Contents

How good is the air quality sensor?

Every Winix has a VOC Sensor.

You know by now, after all your research, that VOC is the acronym for volatile organic compounds. The sensor detects whether these sort of pollutants are present in the air. And adjusts the fan setting to kill them. When the air quality returns to normal, the sensor triggers a drop in the fan setting. Down to the appropriate level.

And as the air sensor does its work. The air quality indicator(s) display the current level of air quality in the room.

Some customer reviews talk about noticing it happening when people are smoking. One review even talks about experimenting with their natural function. Creating a smell and how quick the sensor is to react.

But it’s not the only automatic feature that reviewers comment on. They also talk about the Change Filter Indicator.

Back to Table of Contents

How long do the filters last? How do I know when to change them?

The life of a filter is always important to consider when buying an air purifier.

It’s not just the cost. It’s also important to know when they need changing, how easy they are to change, and how often you have to do it.

All Winix models have a Change Filter monitoring system. There’s an indicator light on the Control Panel which glows when it’s replacement time.

It’s a system that is not time-based. It calculates using age, air quality, and the location of the unit as parameters. So, you are not prompted to replace a filter and spend extra money without need.

Note though that it’s only monitoring the True HEPA filter. The manuals and marketing literature say it should last twelve months with normal usage. In some models, the HEPA filter is washable with a three-month cleaning cycle. But even these only have a service life of twelve months.

Again with the Carbon Pre-Filter, some models have Non-Washable versions. Others have a Washable version. The manufacturer’s recommendation is to change the Non-Washable every three months. And then dispose of it because it’s not re-usable.

It’s handy that your new unit comes with a 4-pack of Non-Washable Carbon Filters. These last you twelve months. With the Washable version, it’s cleaning every three months and renew every year.

But like all air purifiers, this all goes out the door if the air is high in pollutants.

In these situations, it’s anyone’s guess on how long they last. Of course, get rid of the source first and use the air purifier to clean up what remains. Usage then returns to normal and the three months, twelve months cycle starts.

Customers have commented on the process to change the carbon filter. That it’s simple and quick which is encouraging. There is a downside, though. You need the discipline to know the three months is up and to make the change.

Where are they made?

Like a lot of appliances, these days the Winix Air Purifiers come from overseas. Not China, though, but Korea.

To know it’s Korea is important. Because Winix is dominant in the Korean market as a manufacturer of quality products. They cannot afford to compromise that reputation by releasing inferior products elsewhere. The inherent quality of the unit you buy here in the U.S remains the same as in Korea. They haven’t cut out the heart of their units to keep to a price.

Adding to their commitment in the US, they have a customer service office in Illinois. Contact is available via email [email protected] and phone (847) 551–9900. Hours are Monday through Friday, 9:00 am – 5:00 pm.

Call them for technical questions. Reviews are complimentary about their responsiveness to customer inquiries.

Is the warranty any good?

Given their commitment to quality, it is disappointing that Winix only offers a one year warranty on some of their models.

And overall there is no consistency on the warranties offered.

It’s somewhat bewildering and hard to understand the logic:

  • Six models have only a One Year Warranty. PlasmaWave Series 5500, 5500–2, 5300, and 5300–2; FresHome Series P150; Ultimate Pet Series 9500.
  • Two models have a Two Year Warranty. PlasmaWave Series HR1000 and HR950.
  • Three models have a Three Year Warranty. FresHome P450, P300, and B151.
  • Only two models have a Five Year Warranty. Signature U450 and U300.

The warranty is no different to most others in the marketplace. Installation, maintenance, and operation is according to the instructions in the warranty.

If the product doesn’t work, you can return it at your cost to Winix for assessment. The company will repair or replace the air purifier. But only if they agree that faulty material or workmanship caused failure.

Customers do talk about getting a satisfactory outcome in these circumstances.

With issues outside of failure, you may have difficulties in getting resolution.

How to match CADR Rating to your room size

It’s often difficult to determine how effective a unit will be for the size of your room.

Winix, like some other manufacturers, has addressed this issue.

They have all their models certified by the AHAM (Association of Home Appliance Manufacturers). By applying the CADR (Clean Air Delivery Rate) rating system.

It is a test for particulate matter: tobacco smoke, pollen, and dust. It generates a number that indicates the volume of filtered air delivered by an air cleaner. The higher the number the faster is the air filtered.

AHAM recommends a 2/3 rule for the CADR number to estimate the size of the room the unit will best service. The example given by AHAM focusing on tobacco smoke is a room 10 feet by 12 feet being 120 square feet. Two-thirds of 120 is 80. So any unit for a room of 120 square feet should have at least 80 as the Tobacco Smoke CADR number.

This calculation assumes a ceiling height of 8 feet. What if the height is greater than 8 feet? AHAM’s recommendation is “you’ll want an air cleaner rated for a larger room.” Not all that helpful.

A warning about relying on the CADR rating.

CADR is helpful in figuring out the unit for your room size. But be careful about using the CADR rating as your only criteria for choosing an air purifier. There are distinct limitations on the scope and quality of the testing. In particular, CADR does not measure any form of chemical contamination. Not VOC’s or odor pollutants.

Are health issues are driving your decision to buy an air purifier? Do not rely on the CADR rating alone.

Do Winix Air Purifiers clean the air?

There are many positive reviews talking about the effectiveness of their unit.

To get these results you need to buy a unit that is right for the size of the room.

Winix makes a quality product for the price you pay. But customer reviews do talk about them unable to rid the air of chemical vapors. And of overpowering strong odors.

Even purifiers at the premium end of the market struggle. Attack the source of high pollution by either elimination or control. Doing this in conjunction with improved ventilation is always the best approach.

Then air purifiers like the Winix come into their own to mop up and keep pollutants from building up again.

Back to Table of Contents

How easy are they to use?

All Winix units have a modern digital display and operating panel.

Unlike a lot of modern day electronic units, you won’t get confused and give up with the Winix. They’re easy to understand.

When you first switch it on, the unit goes into Auto mode i.e. set and forget mode.

The unit has sensors that test the quality of air in the room. If the quality degrades, the sensor triggers a switch. The fan speed changes to turbo to remove the pollutants in the air. When the air is clean, the unit returns to a lower setting.

It even has a sensor that detects light. So when it gets dark, it switches to the quieter sleep mode of operation and dims the lights on the control panel.

You can choose a fan speed of your choice by pressing the Speed button(s). One press of the Auto button gets you back to AUTO mode. If the unit comes with a remote control, it’s even easier. Again, one press of the button and you don’t even have to get off your chair.

We’ve already talked about the Change Filter Indicator. There is a display icon that lights up when the PlasmaWave is working. Green, yellow, and red lights show the quality of air.

None of the models are heavier than 18.7 lbs, so they are light enough to carry from one room to another. Weight could be a problem though if you have a back problem or other infirmities. Because they don’t have any casters to allow rolling the unit on the floor.

The units are not large. They range in height from 21,6 inches to 25.6 inches. Width ranges from 15 to 18.8 inches and depth from 8.2 to 11.7 inches. So don’t worry about it taking up excessive movement area in your room.

The remote is a useful addition but only comes with the 5500, 5500–2, P450, U450, and U300.

Comparing the 5000 (PlasmaWave) and P (Freshome) Series: Are there any differences?

As a reminder the model numbers are:

  • 5000 (PlasmaWave) – 5300, 5300–2, 5500, 5500–2.
  • P (Freshome) – P150, P300, P450.

The two series have many similarities:

  • A three-stage filtering system. Note there are variations in the components between models. Both the 5300–2 and 5500–2 have an extra pre-filter. See below in the differences section.
  • A smart VOC sensor.
  • Four fan speeds.
  • A filter change indicator.
  • An automatic mode of operation regulated by the air quality sensors.
  • A sleep mode with panel lights dimmed and low fan speed.
  • Energy Star rating.

But there are differences.

Let’s look at them under the following headings:
* Filtration System.
* WINIX PlasmaWave® Technology
* Styling.
* Warranty.
* Remote Control.
* Manufacturer Room Size.
* Programmable Timers.

Filtration System

The marketing blurb talks about the three-stage Air Cleaning or three-stage Air Purification system. And that’s true, but the components in each of the models vary.

Working backward:

The third stage in every model is the WINIX PlasmaWave® Technology.

The second stage is always the 99.97% True HEPA filter. But here’s where it all starts to change.

  • All models have a non-washable version except the 5500. The 5500 should be washed every six months but only for six times which is equal to 3 years usage.
  • The recommended change cycle for the HEPA filters varies. From 1 year for the 5300, 5300–2 and 5500–2 to 1 year and six months for all the P series models. And three years for the 5500.

The first stage also varies between models.

  • All models have a non-washable activated carbon filter. Except for the 5500–2 which has a Washable Advanced Odor Control (AOC™), Carbon Filter.
  • The non-washable filters can’t be cleaned and need replacement at least every three months. The washable filter needs washing every three months and replaced once a year.

And then we have what I’ll call the Pre-Stage.

  • The 5300–2 and 5500–2 have a permanent pre-filter. The pre-filter, in effect, turns them into a four-stage filtration system unit. Which is likely to extend the life of the other filters.
  • This pre-filter is designed to capture large particles like dander, dust, and pet hair. The recommendation is to clean it every 14 days.
  • It means the first stage is washable. And the non-washable filters are all about capturing the smaller particles and reducing odors.
  • A more robust method of purifying the air.

WINIX PlasmaWave® Technology

With the 5000 (PlasmaWave) series you can turn the PlasmaWave operation on or off.
You can’t do this with the P (FresHome) series. Turning on or off is a problem for you if you prefer to run the PlasmaWave only when you are out of the room.


The 5000 series has a grill in the front. All have a silver body except the 5300–2 which comes with a charcoal/black color.

By contrast, the P series has a more modern look with a clean white casing.


All models come with a unit warranty of one year except the P300 and P450. Theirs is three years.

Remote Control

Remote controls come with the 5500, 5500–2, P300, and P450. But are not provided with the 5300, 5300–2 or P150.

Manufacturer Room Size

5000 Series room sizes are 350–360 sq.ft. The P series range from 150 to 300 to 450 sq.ft. As per their model numbers.

Programmable Timer

Only the 5300–2 and 5500–2 have these.

What are the differences in the two HR Series models?

As a reminder, there are two model numbers, HR950, and HR1000.

The two models offer the same functionality with one significant difference.

There is no remote for the HR950. So control is only with the straightforward control panel controls.

The distinctive feature of the HR1000 is it’s Wi-Fi capacity. You can connect it to a smartphone or a tablet using the WINIX SMART App. Thereby controlling the unit from anywhere in your home or when you’re away. The HR1000 is the only Winix model with this capability. If you’re getting close to home, you can switch it on early. To clean up nasties, that might have occurred while you were away. Once home there is no waiting for your purer air experience.

The only other difference is color: white for the HR950 and gray for the HR1000.

Both models have a child lock and child lock indicator that are not available in any other model.

Both models are the same in all their other features:

  • 5 stage filtration
  1. Permanent washable pre-filter cleaned every 14 days.
  2. Non-washable (CD) Coated Deodorization Carbon filter with a one-year change cycle.
  3. Non-washable True HEPA filter with a one year life.
  4. Non-washable Anti-microbial coating on the HEPA filter.
  5. PlasmaWave Technology.
  • Rated by Winix to service 400 sq.ft.
  • Easy to operate Control Panel.
  • Air quality sensor.
  • Auto mode operation.
  • A filter change indicator.
  • PlasmaWave operating indicator and on/off switch.
  • Four fan speeds.
  • A light sensor which triggers sleep mode.
  • Energy Star rating.
  • Warranty is two years.
  • Programmable timer.

Comparing the 9000 (Ultimate Pet) and U (Signature) Series: Are there any differences?

As a reminder the model numbers are:

  • 9000 (Ultimate Pet) – 9500
  • U (Signature) – U300 and U450

The U series have updated versions of the original Ultimate Pet Series.

The primary difference is in the specified room size coverage.

  • The 9300 (discontinued) was 213 sq.ft. The 9500 services 284 sq.ft.
  • Compare this to coverage of the U series which has jumped in size somewhat. The U300 services 300 sq.ft. while the U450 covers guess what? Yep 450 sq.ft. Smile

There are differences in styling as well. The later U models are white in color and have a more modern, cleaner look. The earlier 9000 series have a combined metallic silver and white coloring.

If you’re looking for assurance about dependability, there is another difference. The older based 9500 has only a one year warranty whereas the newer U series has a five-year warranty.

The 9500 has a programmable timer, with settings for one, four, and eight hours of operation. The timer is a nifty feature. If you want to clean the room on the Turbo setting while you’re out but only want it running at that speed for a fixed time. For some reason, the timer is not available in the newer U series.
Both series have five-stage filtration systems. But there is some variation between the old and the new:

Stage 1 – Both series models have a Washable Anti-Bacterial Large Particle Pre-Filter.

  • All have a yearly change cycle.
  • Cleaning is three monthly.

Stage 2

  • The U series have the latest CleanCel® Anti-Microbial Filter Protection Technology. Applied to the Pre-Filter.
  • In the 9500 this stage involves a non-washable True medical grade HEPA filter. It has a yearly replacement cycle.

Stage 3

  • The U series has a washable True medical grade HEPA filter. There is an annual replacement cycle and cleaning every three months.
  • The 9500 has a Nano-Silver Mesh screen providing antimicrobial protection.

Stage 4

  • The U series has a Washable Advanced Odor Control (AOC™), Carbon Filter. With a change cycle of one year and cleaning every three months.
  • The 9500 used to have the older Advanced Activated Carbon Filter for Pet Odors. But this filter is now the same as in the U300.

Stage 5 – Both series models have the WINIX PlasmaWave® Technology.

Every other feature between the two is pretty much the same. Any differences are minimal and not a deal breaker:
* Easy to operate Control Panel.
* Air quality sensor.
* Auto mode.
* Check filter indicator.
* PlasmaWave operating indicator and on/off switch.
* Four fan speeds.
* A light sensor which triggers sleep mode.
* Remote control.
* Energy Star rating.

So Many Models: Which One To Choose?

How then to make sense of all this if you’re looking to buy a Winix air purifier? Which of the 12 models is best suited to your needs?

A good starting point to choose an air purifier is the size of the room. And recognizing there is no use in paying extra for an over-capacity unit.

Small Room (150 sq.ft.): What to buy?

For a small room (150 sq.ft.) there is the P150 (Freshome). Only one choice here so no need to discuss further.

Smaller Medium Room (around 300 sq.ft.): What to Buy?

For a smaller medium size room (around 300 sq.ft.) you can choose between the P300 (Freshome), U300 (Signature), or 9500.

Here the choice narrows down to considering the following differentiating factors:

Filtering System – Choosing between a three-stage or five-stage version.

  • The P300 has a three-stage system which means it is more than $50 cheaper.
  • The U300 and 9500 have a similar five-stage system with the 9500 a little dearer.

Warranty – the P300 has a three-year unit warranty. The U300 is five years and the 9500 only one year.

Programmable Timer – This is only available in the 9500.

Winix Freshome P300

Freshome P300

With every other feature common across all three units, the choice becomes clear. If you have a budget challenge, go for the P300.

Click here to buy the P300 with free shipping at Sylvane.

If budget is not an issue, but you just have to have the Programmable Timer then go for the 9500.

Buy the 9500 at a competitive price and free shipping with Sylvane’s.

Otherwise, it’s the P300.

If your overriding concern is to get the best air purification possible and damn the cost, again it is the P300.

Back to Table of Contents

Larger medium room (350 – 360 sq.ft.): What to buy?

For a larger medium room, there is the earlier model PlasmaWave 5300 and 5500 (350 sq.ft.) or the later model 5300–2 and 5500–2 (360 sq.ft.).

The factors to consider for this sized room are somewhat different:

Filtering System and Warranty

  • All models have a three-stage system with a unit warranty of one year. I’ve already spoken about how unappealing this short warranty period is.
  • All the models have filters that need cleaning or a carbon filter change every three months.
  • The newer 5300–2 and 5500–2 have the Stage 1 permanent pre-filter. It can extend the life of the following stage filters. But does need cleaning every 14 days.
  • The older 5500 has a washable True medical-grade HEPA filter with a normal use life of three years.
  • The newer 5500–2 has a Stage 2 Washable Advanced Odor Control (AOC™), Carbon Filter. But the Stage 3 True HEPA filter is non-washable, and both only have a life of one year.
  • The older 5300 Stage 3 True HEPA filter is non-washable and has a life of one year.

Remote Control – the 5300 and 5300–2 don’t have remote control devices.

Programmable Timer – the older 5300 and 5500 don’t have programmable timers.

Color – all models are metallic silver except the black 5500–2.


  • The newer models can cost $10-$15 more than the equivalent older model.
  • There is around a $40-$50 higher price for the 5300–2 and 5500–2 over the older 5300 and 5500.

From a limited budget perspective, you’ll be looking at the older models. The better value option is to go for the 5500 if you can stretch to the upfront cost. Because of the longer life HEPA filter.

Winix PlasmaWave 5500-2

Winix PlasmaWave 5500-2

For the better air purification experience, you’ll have to go for one of the newer models. Because of the permanent pre-filter. If both a remote control and programmable timer are non-negotiable, then choose the 5500–2.

Click to buy the 5500-2 at Sylvane’s – free shipping and competitive pricing.

If you don’t care about having a remote, the 5300–2 is for you. And same if you don’t like the color black.

Check out the 5300-2 here at Sylvane’s.

Larger sized rooms (400 – 450 sq.ft.): What to Buy?

For the larger sized rooms (400 – 450 sq.ft.) there’s the choice of the P450 (FresHome), U450 (Signature). Or the two HR Series Models HR950 and HR1000.

The factors to consider for this sized room are:

Room Size.

  • HR950 and HR1000 coverage is 400 sq.ft.
  • P450 and U450 service 450 sq.ft.

Filtering System and the Warranty.

  • P450 is the only model in this grouping. It has three-stage filtration and three-year unit warranty.
  • Both HR950 and HR1000 have five-stage filtering and a two-year unit warranty.
  • The U450 has a five-stage filter system and a five-year unit warranty.

The Filtering system in detail.

  • The filtering systems in the HR950 and HR1000 are the same. They have a permanent washable pre-filter with a non-washable Carbon Filter. And a HEPA filter that requires changing once a year.
  • The filtering system in the P450 is non-washable. The carbon filter needs to change every three months. And a HEPA filter replacement every 18 months.
  • By contrast, the U450 has a 100% washable filtering system. Here cleaning is every three months and replacement each year.

Remote Control – the P450 and U450 both have remote control devices. The HR950 doesn’t. But the HR1000 is Wi-Fi enabled with remote control via smartphone or tablet.

Programmable Timer – the P450 and U450 don’t have programmable timers.

Color – all models are white except the gray HR1000.


  • The Wi-Fi in the HR1000 carries a premium. The cost can be over $20 higher than for the HR950.
  • The U450 can cost over $80 more than the P450. Because of the five-stage filter system and longer warranty period.

Great comprehensive article, we have one of the less expensive units for our bedroom and it works very well. We also have two other amazing units from a company called Alen that we also are so impressed with. Especially the lifetime warranty!

Very informative article! I ended up buying a recently released model (6300-2) with 4 stage filtration (pre-filter, carbon, hepa, plasma). Was nice to learn a bit about the availible options and technology!
