Aerostar 12x12x1 MERV 13 Air Filter, 6 Count, ACTUAL SIZE (11.75 x 11.75 x 0.75 ), HVAC, Air Conditioning & Furnace Filter for Allergies, Dust, Pet Dander & Smoke (MPR 1500 / FPR 10), Made in USA

I think that MERV 8 is the cost/performance sweet spot for home air filters. The Aerostar brand protects my air handler well enough without making the blower work too hard. I have a PM2.5 particulate meter that usually displays low single digits, so the MERV 8 filter is restrictive enough to keep my indoor air scrubbed. These filters should be changed every 3 months, and they're sturdy enough to last a lot longer if you forget or procrastinate. They're marked to show correct air flow, and installation is easy.

I’ve been using these Aerostar 12x12x1 MERV 11 filters for the last 5 years, and they are the best quality I’ve found. The size fits perfectly every time, and they do a great job keeping out dust, pollen, and allergens. Reliable, durable, and worth it — I won’t use anything else!

Works great! Reduced our heating bills.

They are easy to install and definitely do the job but the quality could be better. The price is also a lot lower than buying at the store so these are good if you’re going to change your filter often.

I have bought these several times not and have been very happy with the price and quaulity.

Good quality AC filters.

I have severe allergies, and switching to this brand has honestly been a godsend. These filters work incredibly well with dust collection, removing allergens with ease. They’re the best‑quality filters I’ve used so far. They fit my vent perfectly, and while there was a slight bend, it was nothing compared to other brands I’ve tried. The filter remains sturdy against the A/C unit and performs exactly as it should. Overall, a great purchase that has made a noticeable difference in my home's air quality.

Great product
