Every Blueair air purifier utilizes a filter that helps capture and remove potentially harmful airborne pollutants from indoor air. After a long period of use, usually 6 months or a year, the filter will be full and need to be replaced. It’s important to change a dirty filter promptly to allow the air purifier to clean your air as it was designed to. Delaying to change the filter can eventually compromise your machine’s performance and result in less clean air.

Faster cleaning. Blueair air purifiers are specially designed to quickly remove airborne particles that can compromise indoor air quality down to 0.1 microns in size. To make sure your air purifier is working as quickly as it’s designed to, replace the filter as soon as it’s full or when indicated by your device.

High CADR (Clean Air Delivery Rate). A Blueair air purifier with a genuine filter provides a uniquely high clean air delivery rate (CADR*). Replacing dirty filters promptly ensures your Blueair air purifier performs at its maximum, delivering more clean air faster and removing at least 99.97% of airborne particles down to 0.1 microns.

Minimum noise. A Blueair air purifier boasts a unique filter design that rewards with distinctly low air resistance and a high volume of clean air delivered. With a clean air filter it generates minimal noise disturbance, in fact, it works so quietly that you will barely notice it’s even working.

Low energy consumption. When operating with a new filter, the air purifier’s fan can work efficiently as intended, consuming minimal energy. In fact, a Blueair air purifier working at its optimal setting consumes less energy than a lightbulb. However, once the filter is full, the fan will need to spin faster to pass air through it, resulting in more energy consumption.

Using an air purifier is a healthier way to breathe. And, as Blueair’s founder realized, when air is truly clean, it can do so much more than simply prevent disease. Clean air improves sleep, energizes both your body and mind, makes it easier for you to focus and even boosts your creativity.

*Tested on particles down to 0.1 micron according to EN1822.

Your Blueair air purifier will notify you when it’s time to change filters, either by the light glowing red or via your app. Depending on the model and personal use, most filters usually fill up after 6 months of daily use, while others can last up to a year. Whatever the filter’s life span, it’s crucial to replace the filter once it’s full of dirt and pollutants. This ensures your air purifier can work as intended, keeping your air clean and airborne pollutants out of your lungs.
