Frequently Asked Questions
Do washable electrostatic filters really save energy?
Yes—when properly maintained. Washable electrostatic filters with low resistance let your HVAC fan move air more easily than high-MERV, high-resistance filters, which reduces run time and energy use. Clean them regularly to avoid clogging, which can negate savings.
How often should I clean a reusable MERV 8 filter?
Clean every 1–3 months under normal conditions; more often if you have pets, smokers, or high dust. Rinse with water, let fully dry, and reinstall. Inspect for frame damage or media wear and replace when performance degrades.
Can these filters replace HEPA for allergy sufferers?
Not entirely. MERV 8 washable filters are great for dust, pollen and pet dander but won’t match HEPA for the smallest particles. Allergy sufferers may use MERV 8 filters for HVAC plus a portable HEPA air purifier in key rooms.
