Frequently Asked Questions
How often should I replace these pleated furnace filters?
Most manufacturers recommend every 60–90 days for typical household use. If you have pets, allergies, or live in a high-dust area, check the filter monthly and replace sooner if it looks heavily soiled.
Is MERV 13 overkill for a standard home?
MERV 13 is useful if you need extra protection from smoke, pollen or fine allergen particles. However, older HVAC systems may experience reduced airflow with very high MERV filters, so check your HVAC specs before choosing a high-MERV option.
Why do some filters not match the exact listed size?
Manufacturers often list nominal sizes; actual filter dimensions can be slightly smaller to ensure fit in various housings. Always measure your filter slot (height x width x depth) and compare with the product's listed 'actual size' before buying.
