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.

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

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

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

Great product and a good value! Excellent at filtering particulates, dust, and allergens. I only buy these filters and definitely from Sam’s Club.

Excellent filtration and price. I have confidence in the manufacturer and so happy that Sam's carries these products.

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.

I use them all the time-good buy for the price.I wish they were available in all Sam's Club stores (size)

Yellow pollen and pet shedding time is driving my allergies bonkers but it likely would be worse if I was suing the usual filters.
