Area coverage: The A3 Ultra Quiet is rated to fully refresh the air in a space measuring 1,030 square feet two times per hour, though do note that, as with all air purifiers, its effective coverage size is considered to be smaller for allergy sufferers.
Filter replacements: You can buy filter replacements here for $116. While many air purifier filters need to be swapped out every six months, this one can last up to two years.
My experience: My first thought on powering on the A3 is that Rabbit Air isn’t kidding then they say this air purifier is quiet. In fact, when set to a “silent” operating speed, it’s literally quieter than a whisper. And at night, thanks to a built-in light sensor, it reduces its lights (which can change color to represent air quality in real time) fading away into a dim, barely-audible device one could easily forget was even there.
In terms of actually using the device, it’s an easy setup and familiarization process. You can pretty much start using it right out of the box—all you need to do is discard the packing materials and then pop the front panel off the air purifier, exposing the filters inside that need to have protective film removed. On the control interface, you will find air quality indicators, filter status info, and your Wi-Fi connectivity status.
Because this is a fully smart air purifier that you can control remotely in real time via a phone or tablet app, you can also get all the info you’d ever want about your indoor air quality via the Rabbit Air app, available for download at both the Google Play and Apple app stores.
The bottom line: When the Rabbit Air A3 is running, the air in your home will be cleaner—you can count on that based on the intense testing and product comparisons the company runs, not to mention the five-year warranty offered. You can also tell the air is cleaner because it will smell that way, and I don’t just mean a reduction in unwanted odors (though that’s a welcome fact here)—I mean you will literally experience the odor of fresher air, much like going outdoors on a clear, breezy day.

How to check your air quality
There are three primary ways to check your air quality. If you want to go the free route, you can use your phone’s built-in weather app to check the AQI (Air Quality Index) of your location. It won’t be exact, especially if your windows are closed, but it’s an okay estimate. For a more specific air quality reading, you can purchase an air quality monitor (we found a bunch on Amazon starting from $36). Otherwise, if you have an air purifier already, there’s a good chance it has a screen or connected app that will tell you the CADR rating (Clean Air Delivery Rate) of your space.
Types of air purifiers
You might not know that there are actually are a handful of different kinds of air purifiers. The primary aim of each is the same: To filter out allergens, mold spores, smoke, VOCs, and other particulate matter. You can find UV purifiers, which use ultraviolet rays to sanitize surfaces. There are also activated carbon, ionization, and HEPA air purifiers—the last of which is most common for personal use.
