AAF International New Case of (12) 12x30x1 Fiberglass Air Furnace Filter HVAC Filters 8383788

I purchased these air filters simply because they fit my air intake vent, and because the previous brand I found on Amazon is no longer available. (Previously I had been splicing two filters to fit the space. ) These seem to work fine, but they are simply a fiberglass filter in a cardboard frame, unlike the previous version which had a stabilizer built in as well. These seem to do the job, and they fit, so they fulfill my need.

These are overpriced, thin, worthless filters. They arrived with the cardboard framing bent and out of shape thus allowing particles, dust and dog hair to flow right through. They won't fit correctly because of their screwed up shape. Don't waste your money on these cheaply made filters!

can't find these basic small filters locally, only the expensive heavy ones that don't allow much air flow. they work well and fit as they should. great product. 4 stars on sturdiness as they have a thin cardboard surround but are only 30 day filters and don't need to be extremely rigid as they allow air flow greater than the heavy 90 day filters.

Couldn’t find this odd size in big box store. Good to get a bunch at once.

I have ordered these exact filters before. A couple of orders for our old house and now on our second order for our new house. We are those lucky people that have the random size we can't find in our local store. These work perfect and are my go to filters. I would give 5 stars but my only complaint is the smaller filters are more expensive than the larger ones I've purchased previous (all from the same place). However, these are our go to filters and our ac company even says these are the good stuff. I will definitely be making another order in A few months.

A little pricey.

We had a lot of construction dust and changed often. They were perfect.

Used as a prefilter to stop dog hair
