Buying an Air Purifier? Resolve These 6 Key Questions First

Overwhelmed by where to start when buying an air purifier?Don’t know where to start?

You’ve made the decision to buy an air purifier. But the number of makes and models available is mind boggling.

How the heck do you narrow down the field? Let alone make your final choice?

Let’s say goodbye to the pressure and make a razor-focused decision.

We’ll cover six quick steps that save time and ensures you find the air purifier right for you.

Let’s begin.

Step 1 You know why you’re buying an air purifier, yes?

Ok, it seems strange revisiting your why. You’ve already made the decision. But go with me. It’s crucial you know why you’re forking out all that money. And going through the hassle of choosing.

Because as you look at each air purifier, you’ll discard it if it doesn’t match your why.

Sorting out the right air purifier becomes much easier. It either matches, or it doesn’t. If you’re not rock-solid on your reason, you’ll end up buying the wrong one.

So, what is yours?

  • Is it that you or a family has health problems affecting their breathing?
  • Does your child have asthma?
  • Do you suffer from allergens?
  • Sneeze your way or worse through hay fever season?
  • Are you living in a severe smog zone and want to protect your family from the effects?
  • Is your home in the path of smoke and other pollutants that blow your way when the fire season starts up in summer?
  • Is your local area industrialized and pumping out debilitating pollutants?
  • Or do you want to be secure in the knowledge you’re doing everything to protect the health of your family?

Whatever is driving your search, that’ll be the sturdy base for your decision.

Step 2 Have you exhausted pollution control measures? (You could be wasting your money)

Take a second to pause.

Have you considered the advice of the Environmental Pollution Agency (EPA)? They recommend you control the source of your polluted indoor air first. There’s no point cleaning the air if you can reduce or remove the volume of pollutants.

The EPA recommends two approaches.

The first is to control the source of any air pollution. Do you have anything in the home producing pollutants?

  • Any building carpet, furnishings, and other building components producing volatile organic compounds (VOC’s). Like formaldehyde from glues, fabric treatments, stains, and varnishes?
  • Are there any stored supplies such as solvents, toners, ammonia, chlorine, or gasoline? Are they near the house emitting fumes into the air?
  • Is there any damp in the house? The resulting mold could be releasing harmful spores.
  • Plumbing problems releasing sewer odors?
  • Do you use housekeeping or cleaning products containing ammonia, chlorine, detergents, or disinfectant?

If you can combat the pollution sources, you may not need to buy an air purifier.

The second approach is to focus on the ventilation of your house with clean outdoor air.

General ventilation provides one strategy:

  • Infiltration of outdoor air through openings, joints, and cracks
  • Natural ventilation by opening doors and windows
  • Mechanical units drawing in air from outside

A big proviso here is the quality of your outdoor air. No point in letting in air that’s worse.

Consider localized action using exhaust fans as another strategy.

Localized action focuses on removing pollution or dampness in, for instance, the bathroom or kitchen. Consider these questions:

  • Is a specific room polluted or damp?
  • Can you install an exhaust fan?
  • Does an existing exhaust fan need maintenance or cleaning?
  • Should it be stronger?
  • Is it so old that it needs replacing?

So, you’ve actioned all available pollution control measures? You’re ready to look for the right air purifier to clean your indoor air.

Step 3 Do you know your technology?

Different air purification technologies are available. No one technology handles every different type of pollutant. You’ll need to match your health condition to the technology that best suits.

And that matching helps you narrow your range of choice of makes and models.

Step 4 Where are you going to place your air purifier?

Air purifiers are built to clean a particular volume of air. A lesser capacity unit only cleans the air of a small room. Larger capacity machines are suitable for medium or larger rooms. And the manufacturers provide guidance on the best room size for each of their models.

So, you need to calculate the size of the room for your air purifier.

If it’s a large room, don’t choose a small capacity air purifier. Otherwise, it’ll be like the 300 Spartans at Thermopylae. They failed to defend themselves against the 100,000 invading Persians. Similarly, your small air purifier will fail to keep the large room clean.

Another factor is doors. Air purifiers are more effective where there is only one access door. Keeping it closed gives the air purifier a chance to clean the air. It won’t have to battle new air entering whenever the door opens.

But what if you are planning to use the air purifier in a room with many access points?

  • Say a door at one end and bi-fold doors at the other?
  • Or there is a door to the outside?
  • Or is it a room that has constant traffic?
  • People always opening and closing the doors?

In rooms like these, a smaller capacity air purifier struggles to keep the air clean. Every time a door opens, a rush of dirty air enters the room. This is much like when a dam bursts and an avalanche of water hits you. Except that your dam breaks every time a door opens. If this is the case, select a larger capacity unit.

Step 5 Is your budget up to it?

Unless money is no object, you need to be aware of the costs and their budget implication. Click here to calculate your costs. You don’t want any surprises.

You may be able to afford the upfront cost. But what about the ongoing cost of filter changes and electricity places? Does it put undue strain on your weekly finances? At least you’ll know to plan for the necessary sacrifices in other areas of your monthly spend.

Step 6 Features are confusing so decide early

The air purifier you choose must clean the air to address your health need. That’s a given.

But air purifiers come with a range of different features. When you’re in the middle of determining your choice, it is easy to get confused.

It’s then you can thank your stars you sat down and determined an order of priority. You know which features are essential to your choice of model:

  • Do you want a remote to make changes to the operation of the machine without getting off the couch?
  • Do you want wi-fi capability to turn on the unit remotely, so the room is clean before you get home?
  • Or do you know when you’ll be arriving home? If so, look for the unit with an automatic timer for on and later switch off.

And that’s all. Your preparation checklist is complete.

The Path is Clear

Take your time, and be fully prepared to enter the labyrinth of choosing an air purifier.

With the six steps, the task of choosing an air purifier is no longer overwhelming.
