Kit Contents

- 2 × Activated Carbon Freshness Filter Inserts — 8.4" x 2"
Screen Filter — Maintenance & Care
Vacuum every two weeks with a soft-bristle brush attachment. For homes with pets, smoke, or high dust, gently wash with mild soapy water as needed. Allow to dry completely out of direct sunlight before reinstalling.
⚠ Never operate your unit without the filter installed. The second screen filter in this kit allows you to rotate during cleaning without downtime.
Screen Filter — Replacement Guidance
Although washable and reusable, filters lose efficiency over time. Replace every 12 to 24 months depending on your environment and cleaning frequency.
Carbon Freshness Filter — Maintenance & Care
Do not wash or rinse with water — this degrades the carbon media. Vacuum gently every two weeks with a soft-bristle brush attachment. The freshness filter installs inside the pre-molded holder in your main screen filter.
Carbon Freshness Filter — Replacement Guidance
Replace every 6 months. Homes with pets, tobacco smoke, or heavy cooking odors will see faster saturation and should replace at or before the 6-month mark.
Returns & Exchanges
We want every order to go smoothly, and if something is not right we want to make it right. At the same time, for the health and safety of everyone — our team, other customers, and the facilities these products are used in — we cannot resell opened or used filtration and air quality products. Our policy below is built around that reality. If you have any questions about a product before ordering, please reach out — we would rather help you get the right thing the first time than deal with a return after the fact.
