Air Purifiers Filter

Compatible with all major TruSens air purifiers. This combination filter features three filtration stages to combat flu viruses and airborne pollutants. The all-in-one filter system combines a True HEPA filter with an activated carbon filter and a durable mesh pre-filter. Replace every 12 to 15 months, and the carbon filter for allergies and flu every 3 to 4 months (depending on usage).
