Frequently Asked Questions
How often should I replace furnace filters from multi-packs?
Most pleated filters are replaced every 60–90 days. If you have pets, allergies, or heavy dust load, change them every 30–60 days. Multi-packs reduce cost per filter so it's easier to stay on schedule.
Are MERV 8 filters good enough for home HVAC?
Yes—MERV 8 provides solid protection against pollen, dust, pet dander and larger particles while keeping airflow restrictions low. For specialized needs (smoke, very fine particles) consider higher MERV ratings, but verify compatibility with your HVAC system.
What should I do if filters arrive damaged or the size is off?
Inspect packs when they arrive and compare actual dimensions to your return/grille. If filters are damaged or noticeably out-of-size, contact the seller for replacement or refund. Buying from reputable brands and checking recent reviews can reduce risk.
