Superior HEPASilent® technology.

Blueair purifiers combine electrostatic and mechanical filtration, allowing filtration to perform at peak performance levels for longer periods of time. The two types of filtration expertly work together to trap particles from big to small. Learn more

Gradient filter structure.
Gradient filter structure.

Traps particles for good.

The gradient filter structure resembles many filters in one, trapping particles of all sizes while maintaining maximum airflow. The progressive structure resists clogging and won't re-release particles back into the air, even when the filter is heavily loaded.
Filters - Naturally Antibacterial.

Naturally Antibacterial.

The naturally antibacterial polypropylene fibers in our filters prevent bacteria and mold growth, so you’ll never add harmful particles back into the air.

Filters - Environmentally Friendly.

Environmentally friendly.

Our less dense filter design mean lower air pressure, requiring less energy consumption. Our filters are also 100% recyclable, so the only thing you’re adding back into the environment is clean air.
 Less dense filter media.
Less dense filter media.

Whisper silent.

Due to the use of both electrostatic and mechanical filtration, our filters are able to benefit from lower density filter media. Less density allows lower air pressure, so you get high performance with a whisper silent delivery

1. Which units use the 301 Particle Filter?
     The 301 Particle Filter is designed to fit the Blueair 301.

2. How often should I change the filter in my Blueair unit?
     The filter should be changed every six months, or 188 days, to keep your Blueair unit working at its highest efficiency. In ECO10 units, the filter should be changed once a year. 

3. How do I know when I need to change the filter in my manual unit?
     Your magnetic filter timer will keep track of when your filter needs to be changed; its LED light will flash to notify you every six months or 188 days.

4. How do I reset the filter replacement indicator for my manual unit? 

     To reset the magnetic filter timer, press and hold the “RESET” button for 10 second. The filter change indicator light will turn off and the counter will begin its countdown to the next filter change(188 days). To temporarily stop the filter indicator light for five days, press the “SNOOZE” button.

5.  Can Blueair purifiers remove smoke and harmful gases? 

     Yes. Our SmokeStop™ filters are specifically designed for environments with tobacco smoke, auto exhaust, chemical fumes, odors, and harmful VOCs.  We use 2 - 4 lbs of coconut-shell activated carbon, formulated with a unique blend of Potassium Hydroxide and Potassium Iodide, to trap gases and fumes and remove them from your air.
