STEP #1: Learn All 10 Types

I'm often asked: "What's the top air purifier?" My answer is "The air purifier with the right technology, the ones that match your needs."

So you may know what HEPA filters or carbon filters, but before you read any Air Purifier Comparison Review let me ask you two questions:

1) "What are the other 8 technologies?" and

2)"Which of the 10 will help your problem?"

My video below covers the 10 types of air purification and what they can help.

STEP #2: Determine Your Square Footage

The second step involves 1) your square footage, and 2) how manufacturers rate square footage. The first part is fairly easy - measuring the room side to side and multiply. What about high ceilings? Most air purifier square footage is based on 7-8 foot ceilings. For 10 foot ceilings add 25%, Cathedral ceilings 30-40%.

Manufacturers tend to exaggerate square footage and you'll want to allow for that when comparing air purifiers as well. Some technology like HEPA requires that the air going through the machine determines square footage. Other technologies like negative ions and Ozone go out into the room to clean the air, which allows manufacturers to increase the numbers. Most companies numbers are based on cleaning all the air in the room once an hour. However for allergies or asthma you'll want to clean the air 2-4 times an hour for allergy relief.

STEP #3: Review the Comparison Chart

Now that you know the technologies you want (step 1) and the square footage (step 2) you can begin to comparing air purifiers more effectively. The Air Purifier Comparison Review Chart above shows the ten top selling online brands.

A few other things to consider:

1) Find 3-4 models that fit your technology and square footage needs.

2) Be careful to look for the replacement filter costs. Most manufacturers overcharge for the replacement filters which can cost you over time.

3) When comparing air purifiers make sure you also review the warranty policy on the complete reviews for each model. Often warranties that sound good have hidden costs or are pro-rated to the companies benefit.

STEP #4: Watch More Video Reviews

Now that you've reviewed the comparison chart the left menu more detailed written reviews and video reviews, including particle tests on most major air purifiers. These reviews take into account these factors:
