These filters made my furnace not be able to breathe. I had to call a technician to come to my home and it cost me $254 for him to tell me that I needed different filters.

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.

I purchased the Filtrete 90 day filters while an instant value and received a one year supply for $6 off the regular price. I trust these filters to keep my furnace and A/C operating at good performance.

I have to buy filters and replace once every couple of months due to my dogs and this is the cheapest place to find them. They are almost $20 any where else.

These were a perfect fit and are doing a great job! With a pug (known for heavy shedding) and a smoker in the house, these filters have made a big difference in the air quality. Great price and fast ship too.

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.

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.

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.

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.

Great to see these in side the Sam's Club store considering that are a very pricey piece of equipment wherever you go. Therefore seeing then in bulk only helps the customers.
