Nice filters. We buy them when they are on sale. The multi pack is a better deal than buying them individually. They work great! We change them monthly during high allergy times. Can go longer at other times.

I have used 3M filters for years. I would buy the 1500 version at the home improvement stores. Sam's has the 1600 version (better) and it is cheaper. What is not to like?

We have tried different brands because we switch them often and they are a little pricey but they are so worth it. I see the difference in the air quality in my home.

I am always cautious about buying filters by mail because the carriers often destroy them if they are not packed carefully. My filters arrived in perfect condition and I install them immediately without any problems.

There are cheaper filters but these are of excellent quality. One of these filters lasts us about three months. We have a lot of agricultural dirt & grain dust in the area in which we live. The extra filtration qualities are worth the price.

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.

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.

I cannot give you feedback on how they work yet because I haven’t put them in. My concern is why I would pay the same price for a. 20/20/1. 20As I did for a 12/12/1 ????

Great price on a great product. We have a couple of rescue dogs that shed. That means I always have a need to change my filter often and to always use a good one. This fits that perfectly.

Just in time for the start of our spring allergy season as I clean the tree pollen off of the car. I typically use the dust grade until the allergy season arrives. These are an excellent upgrade to capture finer allergens.
