Blueair 400 Series Replacement Particle Filter
Your Blueair 400 series air purifier represents the pinnacle of Hepa air filtration. No other Hepa air purifiers are manufactured to the same exacting standards and with the same attention to detail. In order to maintain the ultimate performance these units provide it is important to replace the filter at the right time.
These replacement particle filters are manufactured by Blueair to the same high standards they employ in their machinery. Perfect seals around the inside of the filter frame ensure the dirty air is processed through the media implicitly and the perfect spacing between the filter pleats ensure an even airflow to maximise filter life and air cleaning efficiency.
This 400 Series Particle Filter fits the following Blueair Models:
Blueair also manufacture special Smokestop™ Filters for use in the above machines.
Below are some differences between Particle Filters and SmokeStop™ Filters that hopefully will guide you to your choice of filter.
Remove dust, pollen, bacteria, pet dander, mold spores and other airborne particles. The particle filter is made of polypropylene, which helps mechanically filter out airborne particles. To maximize filter effectiveness, particles are negatively charged by the Blueair unit before reaching the filters.
Made of enhanced active carbon to remove gaseous pollutants such as cigarette and cigar smoke or other VOCs (volatile organic compounds, including household paints and other chemicals). You may notice a slight odor from the enhanced active carbon when the filter is first used; this will quickly dissipate.

Great filter units, help me a lot. Competetive price & good service.
We purchased the Blueair 450e two years ago. Trawled the internet, did so much research and this product, although one of the most expensive, had the highest rating. Breathing Space offer a professional and speedy service. The product suggests to replace the filter every six months and once the order is placed you can be assured delivery will happen as requested. Would highly recommend.
Very good product, very quick delivery
I live on a busy street, my wife has asthma and we both get hay fever. I bought a blue air 400 for the bedroom to give our bodies some respite from pollen and polution. It works brilliantly, since we put it in our hay fever has subsided to the point it is barely there and my wifes asthma has improved. Breathing space were very helpful during the original sale and deliver the filters promptly each time I order one. Great product, great company.
The desk-top PCs in my office act like vacuum cleaners and draw in any "invisible" dust in the air. They then blow the dust, but in an even finer form, back into the office air. This aggravates my asthma considerably. Since leaving my Blueair 450e running continuously the problem has been solved. The PCs no longer accumulate any significant dust and I no longer have any asthmatic symptoms while in the office. When the filter needed replacing it arrived within 24 hours.
