Frequently Asked Questions
How often should a senior clean a washable furnace filter?
For most households clean every 1–3 months. If there are pets, smokers, or heavy dust, check monthly. Set a calendar reminder to avoid forgetting — reusable filters lose effectiveness if they stay clogged.
Are reusable electrostatic filters safe for allergy sufferers?
Yes — MERV 8 electrostatic filters capture common allergens like dust, pollen and pet dander, which helps many allergy sufferers. For severe asthma or chemical sensitivities, consult a doctor or HVAC professional about higher-MERV or medical-grade options.
How do I measure my furnace slot to buy the right size?
Measure the slot or existing filter from edge to edge and compare to the product’s actual size listed in the description (not the nominal size). If a product notes actual size slightly smaller, choose the next size up or add a small foam strip to stop rattling; accurate measurements reduce fit and leakage problems.
