- What does MERV 8 capture?
- MERV 8 handles dust, lint, pollen and mold spores. It is not rated for smoke, bacteria or fine particles below about 3 microns.
- How often should I wash it?
- Most homes rinse it every one to three months, depending on pets and dust. Wash with water, let it dry fully, then reinstall.
- Will it fit my furnace?
- It is a panel filter, so match the nominal size printed on your current filter and the slot in your return grille. Measure the old filter before ordering.
- Is it better than a disposable filter?
- It saves repeat purchases and keeps similar MERV 8 filtration. Disposables stay cleaner to handle and hold their charge until replaced.
- Does washing ruin the electrostatic charge?
- The charge weakens gradually with each wash. Expect capture to drop over years of cleaning, so replace the filter when it stops holding dust.
- Does the higher resistance strain my blower?
- At 0.25" WG initial resistance it is close to many disposables. Check your system's maximum rated resistance, especially in older or undersized ductwork.
