The Method

Use. Wash. Reuse.

01

Slide it in

Sized for your vent. The steel frame drops into your existing HVAC slot in under a minute — no tools, no fuss.

02

Let it work

MERV-8 microfiber captures dust, dander, and pollen — with the same airflow as a fresh disposable, every single day.

03

Unzip and wash

Every 3 months, unzip the microfiber sleeve and toss it in the washer on cold. Three sleeves ship with every kit — one pre-installed and two spares, so a clean one is always ready.

The smallest change you'll make at home — and the one that pays you back the most.
