Frequently Asked Questions
How often should I replace a MERV 8 furnace filter?
Most MERV 8 pleated filters should be checked monthly and replaced every 60–90 days for normal households. Homes with pets, smokers or high dust loads may need changes every 30–60 days.
Is MERV 8 good enough for allergies?
Yes. MERV 8 removes common allergens like pollen, dust mite debris and pet dander, which helps many allergy sufferers. If you have severe respiratory issues, talk to an HVAC pro before moving to higher MERV ratings.
What if a filter arrives bent or damaged?
Inspect filters on arrival. If pleats or frames are crushed, they can reduce effectiveness and airflow. Contact the seller for a replacement and consider ordering from vendors that use heat-sealed packaging or reinforced cartons to reduce transit damage.
