Winix AM90 Review
The Winix brand has been creating high-quality air purifiers for more than 40 years.
And one of the top benefits of choosing a Winix air purifier is that you’re getting a good unit at a reasonable price.
The Winix AM90 air purifier continues that brand’s tradition and even offers some advanced technology to make it easy to use.
When you add this air purifier to your home, office, or apartment, you can rest assured knowing that you are getting incredibly fresh and clean air without having to tweak a bunch of settings or pay much for it.
Winix AM90 Air Filter Types
Like many other Winix air purifiers, the Winix AM90 offers a four-stage air filtration system with the following filters:
- Pre-filter – This filter is in place to capture the largest particles that are in the air. This includes substances such as dust, dirt, hair, and lint.
- Activated Carbon filter – If you have any smells or odors in your home that you want to remove, then you need an air purifier with this filter. It also has the ability to get rid of gaseous pollutants, airborne chemicals, and volatile organic compounds (VOCs) that might be drifting around your indoor space.
- True HEPA filter – Only the highest-quality air purifiers have this filter because it has the ability to remove more than 99.97% of particles down to 0.3 microns in size. This includes items such as ultrafine dust, pollen, mold spores, pet dander, and bacteria.
- Winix PlasmaWave – This feature makes the Winix AM90 air purifier stand out from the competition. It uses special technology to put air into a plasma state that reacts with water vapor to break apart pollutants like bacteria, viruses, and VOCs to keep your indoor air as healthy as possible.
Winix AM90 Room Size Coverage
The Winix AM90 air purifier is a good air purifier for medium-sized rooms.

Here's how other Winix air purifiers we've reviewed compare:

Winix AM90 ACH Rating
As we continue on with this Winix AM90 review, it’s helpful to know how many times an hour this air purifier cleans the air in a given space.
This is referred to as the ACH rating which is short for “Air Changes per Hour.”
An air purifier could have the best air filters in the world, but if it can’t exchange the air more than once per hour, then it’s not a good choice.
The Winix AM90 has a 4x ACH rating.
This unit has the ability to clean the air in a room up to 360 square feet four times in one hour or once every 15 minutes.
That’s a good ACH rating to have.
Winix AM90 CADR Rating
No matter where you go in your home, apartment, or office, you’ll likely be exposed to some common air pollutants, including pollen, dust, and smoke.
To make your air clean, your air purifier should be able to efficiently remove these contaminants.
By removing those particles, the air purifier will also do a good job of removing other pollutants too.
To ensure that an air purifier is capable of removing the three most common pollutants, the Association of Home Appliance Manufacturers (AHAM) puts it to the test.
The results are the CADR rating which is short for “Clean Air Delivery Rate.”
The Winix AM90 CADAR ratings include:
- Dust: 233
- Pollen: 240
- Smoke: 230
If the numbers are 2/3 of the room size coverage, then the air purifier does a great job of removing these particles from the air.
The Winix AM90 air purifier has good CADR ratings for cleaning the air.
