These HEPA H12 filters (MERV-17 equivalent) have been rigorously lab tested by SGS USA. More than 99.9% effective at filtering and capturing airborne allergens. This includes outstanding effectiveness against allergens such as pollen (hay fever), dust mites, pet dander, and mold. Also, highly effective at filtering out airborne viruses.

Each HEPA H12 filter lasts up to 200 hours or approximately up to 3 months of use. However, if you are using your wearable air purifier for less than 200 hours, we do recommend changing the HEPA filters after 6 months to maintain optimal performance. For further convenience, the blue LED light will illuminate when it’s time to replace the filter.

Also included, hand-washable & reusable pre-filter that helps to extend the life of the main filter.
