Replacement HEPA filter (2 pack) for the QT3 portable air purifier. HEPA filters capture particulate pollution like PM2.5, dust, and pollen. HEPA filters are the key to clean air, so make sure to replace them regularly. The QT3’s HEPA can give you up to 800 hours of clean air.

We recommend changing the filter after 800 hours of use. The QT3 has a built-in feature to remind you when 800 hours of use have passed. 

Please do not wash your filters with water because it decreases performance.
