I purchased some of these at a different site and failed to note they were 5 inches wide!! I got four of them!! I purchased these to replace those.

Good deal for 4 of these filters. We live in SC and the pollen levels have been high so I only trust these especially during the pollen season.

Great Buy! I have used this product in the past and I know I will get the experience every time I buy this filter.

Have not opened these yet but it is a product I use almost exclusively and is always a good performer.

Bought these filtered because the other cheaper brands weren’t doing the job very well. These work much better at catching more dust.

Best Effort with Animals but requires changing monthly or I find dust starting to get inside duct intake

These work well along with my air purifier to keep dust down in our home. I purchase every January and with a pack of four they last the whole year.

Four pack of 12 x 12 air filters cost $20 ea at Home Improvement stores. So four pack for $39.99 is a deal.

We purchase these quality filters (2-sizes) every 12 months at a great price compared to other stores!

These are the very best filters that you can buy. Sure hope they keep them in stock and available next year.
