What’s inside
- 2 true high‑efficiency filters for strong particle capture
- 2 activated carbon filters (odor and smoke management)
- 6 washable pre‑filters to trap larger debris and extend main filter life
How filtration works
The set supports a multi‑stage filtration approach. An ultra‑filter layer targets fine dust, pollen, and pet dander, while the activated carbon filters help reduce odors from cooking, pets, and smoke. Pre‑filters catch hair, lint, and other larger particles, helping the main filters last longer between changes.
Odor control and materials
The activated carbon is made from FSC‑certified wood, combining sustainable sourcing with practical odor control suitable for everyday living spaces.
Value, ease of use, and replacement guidance
This 10‑pack covers several maintenance cycles, reducing shopping trips and ensuring ongoing purifier performance. The components snap into place quickly with no tools required. Typical replacement intervals range from 6 to 12 months, depending on usage and environment.
Care and replacement tips
- Replace the main filters every 6–12 months, or sooner in high‑use environments
- Wash pre‑filters as needed to extend the life of the main filters
