Filtrete 12x12x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

Used in my heating system

I find them cheaper than hardware stores, very economical

It does what it says which is to filter particles (especially those bearing viruses) out of the air.

This is the only filter I use for my HVAC system. It was really hard to find them during 2020. Very glad to have them back in stock.

Very convenient to order through Prime for prompt delivery. They never have my size at the local hardware stores and most online companies want you to order a case at a time. I dont have storage for this! I really wish I could order just one at a time but having to store 1 is not too bad. Will definitely order again!

These are pretty amazing. They don’t last too long, but that makes sense, they’re supposed to pull allergens and dirt from the air to filter it. So, with a good filter, they shouldn’t last long. With two dogs, I feel so much more confident with these filters!

I like having this item shipped and not having to go to Lowes or HD. Packaged well no damage.

Received incorrect size originally. Amazon made good immediately. Correct size identical to what I buy locally, but much less expensive. The 2-pack came in 3M shipping box. Installed easily. The box arrived with a damaged end, but did not damage product such that it couldn’t be used properly or effectively. That wasn’t sellers fault.

They are a little oversized for the opening in my place, but I like a tight fit for filtering air. I change them every three months. If we have a fire in the area, I can sure tell it by the filter.

OK, heres the deal. Brand new modular house in the Midwest (northern Michigan), delivered in January. Bought A/C - it was optional - just in case wifes allergies would flare up. Today they did. She took a Claritin and it helped some, but then after an outing, returning home, she started sneezing about every 4 seconds. She was miserable! So was I. Threw a new one of these into the HVAC system, turned on the A/C, her symptoms subsided in minutes. I mean literally in about 4 minutes. If you love someone with allergies, you will know how terrible it is when you cant do anything to help them. I wish these filters had been available when my son used to suffer from seasonal allergy. This is not a luxury purchase. Now, I have not done a side-by-side comparison test, though I do have some less expensive filters sitting there just in case - or maybe Ill throw those in, in the winter months (which is about 7 months per year here). So, other filters might be just as good. I dont know and I dont care - Im gonna keep buying these because I love my wife and want her healthy and happy, not miserable.
