Frequently Asked Questions

What does a MERV rating of 8 mean?

A MERV rating of 8 means the filter captures at least 90% of particles between 3 and 10 micrometers in size, including dust, pollen, mold spores, and pet dander. It meets ASHRAE standards for quality residential filtration and is recommended as the minimum rating for homes.

Are MERV 8 filters good for allergies?

MERV 8 filters offer a good baseline level of allergen reduction, capturing pollen, dust mites, and some mold spores. However, for households with moderate-to-severe allergy or asthma sufferers, we recommend upgrading to MERV 11 or MERV 13, which trap smaller allergen particles with higher efficiency.

Can I use a MERV 8 filter in any furnace or AC system?

In nearly all cases, yes. MERV 8 filters are compatible with virtually all residential forced-air HVAC systems, like furnaces, central air conditioners, and heat pumps. They create minimal static pressure, so even older or lower-capacity systems can run MERV 8 without performance issues.

What’s the difference between nominal and actual filter size?

Nominal size is the rounded number printed on the filter frame (e.g., 20×25×1). Actual size is the true physical dimension, which is typically about 0.25" smaller per side (e.g., 19.75" × 24.75" × 0.75"). Always verify the actual size of your slot before ordering. If you're unsure, measure the opening with a tape measure.

How long do Simply Filters MERV 8 filters last?

Up to 90 days under normal conditions. Homes with pets, children, or heavy indoor activity may need to replace filters every 30–60 days. Check your filter monthly. If it looks grey or visibly clogged, it's time to swap it out.

Do you offer custom MERV 8 filter sizes?

Yes. If your system takes a non-standard size, Simply Filters manufactures precision-cut custom filters to your exact specifications. Contact our team or use the custom filter tool on our website.

Every size, fast delivery

12 x 12's are hard to find at my local hardware stores, I was cutting a 12 x 24 in half which worked, but these are much better. Also, this has to be the quickest delivery I ever had from Amazon, on my doorstep in 4 hours, no joke.
