This is a cut-to-size roll of blue polyester fiber filter media rated G4 / MERV 6. It traps dust, lint and pet hair while keeping airflow high, and you rinse it with water and reuse it instead of buying disposable filters. It suits odd-size vents, window ACs, purifiers and dehumidifiers where pre-cut filters don't fit. Against disposable MERV 6 filters it trades the rigid frame and exact fit for trimming flexibility and reuse; it captures only large particles, so it is not a substitute for a higher-MERV filter on allergies or fine dust.

This is a cut-to-size filter media with a G4 / MERV 6 rating. It is meant for furnaces, central air conditioning units, window units, air purifiers, dehumidifiers, range hoods and ventilation systems.
The filter is made of blue polyester fiber and has an open fiber structure that allows airflow. The material is flexible, so it can be trimmed to fit a standard or custom-sized vent opening, unit or purifier. The blue color makes it easy to see when the filter is dirty.
The filter is washable and reusable. To clean it, rinse it with water, let it dry completely, and put it back in use. It can also be used in pet areas, workshops and other places that need extra dust control.
