- Will this fit my furnace?
- It fits mobile home furnaces whose model starts with CMF, CMF2, MOC, MAC or CMH. Check the data plate inside the furnace door before ordering. Other prefixes use different filter sizes.
- How often should I wash it?
- Rinse it every few weeks in a running season, or whenever it looks gray with dust. Let it dry fully before putting it back so the blower does not pull in moisture.
- Does it filter as well as a pleated filter?
- No. The quarter-inch foam is coarser and has far less surface area, so it catches lint and large dust but lets finer particles through. It is meant for cabinets designed around thin foam.
- Can I vacuum it instead of washing?
- Yes, a soft brush attachment removes loose dust quickly. A rinse gets out the embedded dust that vacuuming leaves behind.
- How long does one filter last?
- With regular washing, expect several months of use before the foam thins or tears. The four-pack lets you rotate a dry spare while another dries.
