Not always easy to find correct sizes or MERV rating, so when I see them on sale, I have to get them!

I jumped on these filters because they were priced below LOWES and Home Depot where I was buying them!

Very difficult to put in place… very tight fit. Since the filter goes into the ceiling, it is really a struggle to get the filter to fit properly.

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

I have not use but I have order before and use the brand but this time the price was higher and no rebate or discount,

Great product last longer than other semilar filters and you can definitely breathe the difference. Price at Sam's is best deal we have found .

I have been buying these filters for many years, and they really do the job. Specially, if you have allergies, I would recommend them. Good buy

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

Possibly the best whole-house air filter there is, the $10 discount is greatly appreciated in these difficult economic times!!!

Excellent filters, I have 2 dogs and bad allergies, these filters make all the difference in how well I breath.
