The best filters with great results

A bit to pricy as it is recommended to change every 6 months, but these filters are top quality, and handle large volume of air. I change them every one year, well worth it!

Quick and efficient!

The pictures show a pack of three filters. Blueair air purifier requires three filters at a time. Only ONE filter was delivered! The price I paid for this one filter is more than double what’s in the local market.

I had to chase the carrier around in order to have them delivered after a two-day delay already, but apart from that everything else seems OK. The filters are the real ones and they don't smell. In the past, we have had SmokeStop filters that smelled like they were scented, but not these.

The bottom filter is the “as new” filter I received from Amazon, obviously I did not use it as this is clearly a health hazard.The top filter is one I purchased from a reputable retailer.

der Filter so we der Blueair sind nicht billig aber der Filter ist super fuer eine allergy person we ich , jetzt kann ich atmen und have diesen filter seit Weihnachten und nicht mehr abgeschaltet, einfach super und even wenn ich zustimmen muss der preis ist hoch alle 3 monate ABER ER HILFT so hoffen wir dass eines tages ein Angebot here bei Amazon kommt um es billiger zukaufen , thanks Amazon if this may be :-)

These are (the inferior) Particle Filters not SmokeStop filters.
