BlueAir 105619 Replacement Filter for Blue 3410

Blue 3410 Combination Filter
Combined particle and carbon filter for the Blue 3410 air purifier. The combination filter cleans the air of particulate matter like pollen, dust, pet dander, mold spores, allergens, viruses and bacteria. The carbon filter also removes smoke, odors, gases and VOC's. Blueair's world-leading filter technology uses a unique combination of both electrostatic and mechanical filtering, which means that the filtration medium can be made less dense. Less power is required to push air through the filter, which provides the highest performance at all speeds and quieter air cleaning.

When Is It Time To Change Filters?
The touch button on the Blue 3410 tells you when it's time change filters every six months (based on operation time, not calendar days).
