Top 15 Best Air Purifier Reviews

For our first air purifier review, this Honeywell air purifier is our standout winner. What makes it so good?

It is arguably the best HEPA air purifier: you’ll breathe easier if you have asthma or allergies

Bigger particles, along with VOCs (volatile organic compounds), are first filtered by an activated carbon pre-filter. (Replace this filter every 3 months for best results.)

The HEPA medium will last a year and removes 99.97% of the tiniest particles down to 0.3 microns. You’ll get clean and fresh air, free of pathogens and allergens.

For a whole house air purifier (capable of coping with larger spaces) the Honeywell HPA300 is a modern classic.

How to Choose the Best Air Purifier for you?

In our hunt for the best air purifier 2019, we’ll be walking you through a broad spread of models so you can easily find the most fitting purifier for your home.

Coverage Area

It’s crucial that you match the coverage area of the air purifier to the size of your home. Shortchange yourself, and you’ll overwork the purifier while not adequately cleaning the air. Opt for an overly large purifier for your needs and you’ll squander electricity needlessly.

Some compact models have large coverage areas, so don’t think you’ll be limited to hulking air purifiers if you have a larger home.

The coverage area is measured in square feet.

Noise Levels

Noise levels are expressed in decibels, and most air purifiers kick out some degree of noise.

Many have multiple settings allowing you to dial the unit back overnight if you have it in the bedroom.

We will draw your attention (throughout this article) to noise levels so you can make an informed purchase.

What can you do if you want something super-silent, then?


A fan-less air purifier will run much quieter, but it comes with a severe drop in overall quality. In fact, the quality of these products is so low that we can’t, in good conscience, recommend them. Stay away from any fan-less air purifier.


You should look for purifiers that use HEPA (high-efficiency particulate air) filters.

These are the gold standard of filtration, rigorously lab-tested to trap all particles down to 0.3 microns. (Airborne contaminants that are 0.3 microns are too small to see, but you still breathe them in.)

Also, an activated carbon filter medium works well to combat smells.

Make sure the air purifiers on your shortlist provide the filtration you need.


You may not know this: ozone that is discharged into the air can damage your lungs.

Why does that matter? Because some air purifiers feature negative ionizers, which can sometimes actually produce ozone. For the safety of you and your family, if you are going to purchase a product that uses ionization, ensure that it is ozone-friendly.


If you plan to purify the air in your home when you’re out, it pays to use a programmable model or one with auto shut-off.

Some purifiers even allow for remote access or hands-free control with your favorite digital assistant. is a participant in the Amazon Services LLC Affiliate Program, an affiliate program designed to provide a means for sites to earn advertising fees by advertising and linking to
