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.

Filters Are great. We have 3 cats that adopted us and a lab my son adopted to us and these filters handle the hair and dander just fine . Not to mention they’re better value than the merv 11 I was gettin online.

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.

These are great filters. They are thicker and sturdier that other ones. We change our monthly and they capture the dirt and odors. Cost is the best compared to home stores.

Been using these for 3.5 years now and they are doing a great job plus when you buy them at Sam's on sale, that even a better thing cause it's a great deal!!

I I bought generic ones in the past. However, I will not buy them again. I love the Filtrete filters. I’m not dusting as much as I was before. Love the filters.

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.

4 pack that is in stock at the Sam's Warehouse. When on sale, I purchase them, and with no expiration date, change the filter at my home once a month.

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.

Best filters I have found for our home. Very pleased with them. You should change your filters every 30 days, however, I have gone 6 weeks with these and still had good filtration and flow.
