Healthway Deluxe Professional Pre-Filter Replacement Filter

The 7-Stage Pre-Filter:

• Stage 1 - Poly Propylene Mesh: Large particle collector of dust, hair and lint
• Stage 2 - Anti-Microbial: Inhibits bacterial growth in filter
• Stage 3 - Zeolite Pellets: VOC/Gas Adsorbent
• Stage 4 - Carbon Pellets: VOC/Gas Adsorbent
• Stage 5 - Potassium Permanganate: VOC/Gas Oxidizer
• Stage 6 - Anti-Microbial: Inhibits bacterial growth in filter
• Stage 7 - Poly Propylene Mesh: Large particle collector of dust, hair and lint

The manufacturer recommends that you replace the filter every 6 months (based on usage).

However, the Healthway Deluxe Professional Air Purifier features a sensor which automatically detects when the filter needs replacing.
