The A-Series is equipped with PFF-9 technology which is a 9 Phase Filtration Formula that has the capability of capturing and eliminating the widest range of pollutants such as viruses, bacteria, allergens, odours and more.

The first filter, the Pre-Filter, is washable. We recommend washing the Pre-Filter once every 1-2 months.

The remaining filters should be replaced to maintain optimal performance.

Depending on usage, the average filter change is every 4 months. The A-Series smart sensor will detect and notify you when it is time to replace the filters.
