How to Buy an Air Purifier

Pure Air

Ah, fresh air. There is nothing quite like it. I can almost feel the cool, fresh air on my face when I look at the picture.

The problem is, often times our homes are filled with allergens, dust, mold spores, pet dander and more - which keep us from having that experience in the place where we spend most of our time.

Enter Air Purifiers.

Air purifiers filter out the air in our room, getting rid of all those nasty allergens and spores that make us sick and uncomfortable.

Here at PleasantRoom, we want everyone to be able to be comfortable in their own home, and we want to help you find the products that can help you achieve that.

If you are looking to become an expert in air purifiers, I hate to break it to you but, this article is not for you. You don't need to know how they work, you just need to know which ones work best for you.

What we want to do is help you understand the main factors that you should consider before purchasing an air purifier, so you can find the one that will be perfect for you and your home. So let's get to it.

The Key Factors for Buying Air Purifiers

Simply put, there are two main decision points when determining what Air Purifier is best for you. They are:

  1. What is the size of the room?
  2. What are the main allergens, pollutants, or particles you are trying to remove?

Let's dig into those a bit deeper.

What is the size of your room?

Room Size
We all work hard for our money, so there is no point in spending money on a super sized, hefty air purifier for your 300 sq ft bedroom.
When looking to buy air purifiers, look to see how many square feet it is rated for. All of the products we sell here at PleasantRoom list that information in our product descriptions so you can make an informed decision.
If you are trying to purify a small room, one of our Manufacture Partners, Surround Air, makes a very affordable unit meant to purify rooms 500 sq ft or under - all for only $137. Check out the Multi-Tech XJ-3000C.
For larger rooms, check out Austin Air's very popular unit for large spaces up to 1500 Sq Ft - The Bedroom Machine.
If you are unaware of your room's sq ft, it is pretty simple to calculate. Take a tape measure and measure the width and length of the room and multiply them together. The result is your room's sq ft. For example, if your room is 11 feet wide and 14 feet long, your room is 154 sq ft.

What Specifically are You Trying to Remove?


Now that you know the size of your room, it's time to figure out what type of purifier is right for you.

The most common problems people buy air purifiers for are:

  1. Allergies
  2. Asthma
  3. Mold
  4. Pet Dander
  5. Micro-organisms
  6. VOC's (Volatile Organic Compounds)
  7. Smoke Odor

The good news is the majority of these can be taken care with a HEPA filter, which the majority of the purifiers have. HEPA filters remove about 99.97% of airborne particulates, including allergens, mold, pet dander, dust and pollen.

For micro-organisms, you will want a system that has an air sanitizer, which uses heat or UV light that goes through a machine.

For VOC's or smoke odor, you will need something more than a HEPA filter, as those particulates tend to be smaller than what the HEPA filter can catch. What is most effective for VOC's and smoke odor are purifiers that include activated carbon or Zeolites that can absorb those chemicals.

We recommend the Austin Air series of Purifiers for these, as they all have activated Carbon as well as HEPA filters.

Putting it All Together

In summary, when deciding on a air purifier to purchase, it is important to understand your room size, as well as what particulates you are trying to filter out.

If you are looking for an all around purifier that is up for just about any problem you can throw at it, we recommend you find a purifier with a HEPA filter as well as activated carbon.
