Aerostar 16x25x1 MERV 11 Air Filter, 6 Count, ACTUAL SIZE (15.75 x 24.75 x 0.75), HVAC, Air Conditioning & Furnace Filter for Dust, Pet Dander, Smoke & Allergies (MPR 1200 / FPR 7), Made in USA

Thieve are great filters for my furnace. They fit just right. They are a good value when you buy them this way (rather than one at a time). They worked very well. I’m not really clear on the MERV thing but, these worked just fine.

These are great filters for a much better price than our local hardware store!

Exact fit for my older furnace and good quality

Great product. I have a central heat pump, so I replace these monthly. The house has 4 dogs and 2 cats, and it keeps the air pretty clean.

These keep your unit functioning

These work very well best price I found so far.. well shipped .

What can I say. They work great.

Perfect fit. Top quality material. Made in USA. Better price than the local big box store. What more could you want? Highly recommend.

Received quickly. I've been using the Aerostar filters Merv 11 for two years. I have used other brands and I have discovered that the Aeorstar cardboard frame is more sturdy than cheaper brands or even common store brands like 3M. My furnace and A/C has a very powerful 2-stage fan that will cause cheaper/flimsy brands to become warped which allows dust to pass by the filter. The Aerostar filter is more effective at capturing dust and I change them every 6 to 7 weeks. If I leave them in for longer, the filter becomes clogged and dust starts to escape around the edges. At roughly $15 per filter it is worth it to change them more often and keep your house really clean.

I didn’t know what a MERV rating was but once I researched it I found out I’ve been using the wrong filters these MERV 11 filters are a great price for 6 qty and made very well. I’ve had some from other places and the fall apart inside my furnace causing the fan to stop working. These filters will NOT do that and they let enough airflow through as are electrostatic charged to catch all the fine particles.

Does a good job of cleaning the air in the house. Only slight restriction to the air flow, and seems to last long.

Monthly replacements, work well and are inexpensive.

Just received these today and compared them to the big brand name ones I used to use (3M). They are identical in size and construction with the same number of pleats for both. I purchased the Merv11 rating and they look as they will work just fine. No problem with fit or construction and I will try to update once they have been in use for a bit.
