Hi quality filter that works great. We change the filters every three months, seems about right here in the desert southwest. Great price at Sam's for a 4-pack, and usually in stock when we need to restock.

These filters catch the dust and pollen that others let through. I am very pleased with these filters, they are not as inexpensive as the others but do a better job., NO MORE SNEEZING.

I’ve had a “smell” that I couldn’t place and I thought it may be coming from the register area. Wasn’t strong very faint. These filters are higher quality and it did the trick. Worth every penny.

Been buying these filters for a while, they work perfectly in our house and really help eliminate odors, dust and other issues. Price is great when on sale and we stock up on them. Would definitely recommend them.

These filters arrived quickly and neatly packed. The value for the 1600 style filter is very good considering I have paid more for a lesser quality filter from another online retailer. I’ll order these again.

I had been using a cheaper change every month filter and decided to try these. They are made much better so thinking they may last two to three months. So far happy with my purchase.

Excellent whole house filters that don’t degrade under heavy air flow as others I’ve tried. A bit pricey, but worth it the peace of mind and allergen reduction.

This model filter is the best. It's a full boxed filter so it holds up well in a strong blowing ac. Doesn't cave in like lot of other filters. And filters good also. Always purchase these. Good price for four pack.

Comes in a pack of 4. Hard ro find size. Got tired of waiting to order elsewhere. Friend came over and easily replaced. I have asthma and know when it is time. Have ordered them before.

Filtrete is the best replacement filter you can buy. I have a lot of allergens I have to fight and this filter helps me do just that. I have tried other filters in the past but will never buy anything other than Filtrete.
