Best air purifiers that work with Alexa in 2022

An efficient way of improving the air quality inside your apartment or house is to use an air purifier. With the advancement of technology, you can now get a smart air purifier with Alexa compatibility. This air purifier will not only filter the air inside your home but also give you real-time information regarding the quality of air in your home.

A smart air purifier is not very different from a traditional air purifier. The difference is that the former gives you better control of the purifier and feedback on the indoor air quality.

Smart air purifiers come with a mobile app for automated access. With the app, you can switch on or change settings on your air purifier from any location, even if you are away from home.

Just like any new technology, some brands have done it better than others. To help you steer clear of inferior smart air purifiers, we have done extensive research and listed down the top 5 best smart air purifiers that work with Alexa.

Things to consider when choosing an air purifier that works with Alexa

Keep these things in mind when buying an air purifier:

Type of filters

Go for an air purifier that has HEPA filters. These are more efficient and capable of getting rid of 99.97% of airborne particles as small as 0.3 microns. Most air purifiers nowadays have more than one filter. However, the HEPA filter is one of the best and should be among those filters.

Coverage area

Measure the size of the room you intend to use your air purifier and choose one that can cover the entire space. The last thing you want is to move your air purifier often or get a second one to purify the entire space.

Noise levels

Go for an air purifier whose noise level is less than 50 decibels. You don’t want an air purifier that hums so loud that you can’t get anything else going. In fact, if you intend to use it in the bedroom or overnight, go for the lowest noise level or one that has a night mode.

Speed settings

A good air purifier has at least three-speed settings namely: low, medium, and high. A lower speed allows for continued cleaning, medium for less noise and disturbances, and higher for maximum purification.
