Blueair 1 Micron Test

Particle Removal Efficiency

Blueair's HEPASilent™ filter technology captures 99.97% of particles that are 0.1 micron or larger in size. If you find other manufacturers also claiming such particle removal efficiency - ask to see their independent testing.

3-STAGE PROGRESSIVE FILTER

Like having 3 filters in 1.

Why do Blueair filters trap six times more dirt than filters in typical air purifiers?

The reason is the filter’s progressive structure. Most filters from other air purifier manufacturers are thinner and usually consist of the same size fiber throughout. Blueair filters have millions of ultra thin fibers in three different sizes. Thus, the name progressive. The first layer captures larger particles like pollen & dust. The second and third capture smaller particles like bacteria and exhaust.

Our filter design resists loading or clogging and continues filtration at peak performance levels longer. When the filter needs to be replaced (every six months), just open the lid, lift out the old filters and drop the new ones in. No screws, hooks or tools and less than one minute of your time is required. Blueair filters require no weekly additives or filter washing.

Background

The efficiency of an air purifier indicates how much of pollutants are removed from the air when the air passes through the system once. Note that efficiency does not show the volume of filtered air. Only in combination with high airflow is high efficiency an essential component in good air purification.

  

Blueair Testings and results

Camfil Components, Sweden - 2000

In 2000, a test on the HEPASilent™ filtration technology was conducted in Sweden at Camfil Component

AB. The test showed the total efficiency of 99.97% in capturing particles down to 0.1 microns

in size. The test was performed on a Blueair 501 unit placed in a space of 1.2x3 m2. Airflow was 150

m3/h. Elapsed testing time was 120 seconds.

LMS Technologies, Inc. 2010

The high efficiency results from Camfil Component AB has been confirmed by other laboratories

tested elsewhere such as in the U.S in 2010 at LMS Technologies, Inc. This test was performed on a Blueair 650E unit.  

  

Bacteria, Virus and Mould Removal Efficiency

Bacteria filtration efficiency

Natural reduction of airborne bacteria is shown as reference in the graph. The bacteria level after running the unit for 10 minutes is 99% lower than the natural reduction. After 20 minutes, the level is over 99.9% lower.

Mould filtration efficiency

Natural reduction of airborne mould spores is shown as reference in the graph below. After running the unit for 10 minutes, the mould level is over 99.9% lower than the natural reduction. The reduction is consistent after 20 minutes.

Virus filtration efficiency

Natural reduction of airborne virus is shown as reference in the graph. The virus level after running the unit for 10 minutes is 99% lower than the natural reduction. After 20 minutes the level has been reduced by more than 99.9%.
