Air Filter Types

Like many other Winix air purifiers, the Winix AM90 Wi-Fi air purifier 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.

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 room air purifier 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.

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 CADR rating scale of:

• 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.

Top Features

• Automatic Mode – Working with the Smart Sensors, this mode ensures that the air purifier is constantly circulating clean air without any user input. You can literally set it and forget it.
• Sleep Mode – If the lights in the room are dimmed or turned off, this sensor will notice and adjust the fan speed to the lowest setting. It also reduces the brightness of the LED lights on the control panel. This ensures that you aren’t disturbed while you are sleeping.
• Air Quality Indicator – This light is located on the top of the unit and shows you real-time information about the quality of air in the room. The LED light colors change from blue (good) to amber (fair) to red (poor).
