We have people in our house with allergies and asthma. These filters have proven to clean the air from our HVAC better than others we've tried. The sale price at Sam's is the best value we've found.

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.

With two heavy shedding canines in the house along with the dust that magically appears daily, these filters a must in our house. They really trap an amazing amount of "stuff" which helps to clean the air in our house.

Fair price and high filtration. We change the filter at the start of every new season so four will last one year. They are well made and indeed do the job.

Love these filters!! I have been using them for a number of years now and have figured out that changing them out every two months works best for me. I try never to run out of them even if I have to buy a single filter elsewhere occasionally.

Great Filters to use, our service guy said we could go up to 3 months before changing them out with good filters. We change them every 4 - 6 weeks but knowing we could go longer using a good filter is good to know.

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 ????

Have routine a/c filter change etc in Oct but looking at the same size, same company the new one looks 5 inches larger. Waiting to see if it will work. Strange

I like this product. Seems to catch more airborn particulate than the cheaper filters. I have 2 rambunctious kittens, always stirring up dust bunnies while playing.
