These work great. I’m so glad Sam’s carries this size. These usually last 3 months between filter changes. In the summer when my system runs a bit more I’ll change the filters every 1-2 months.

Love these filters although I change every month versus every three months. I have extreme allergies + a cat + a dog + 2 teenagers so they get used up monthly.

These are always a good buy when they are on sale at Sams. They work well and if you forget to change out they can hold up and extra month as they filter out pollens that enter through open doors etc. They do a good job for a merv rating of 11.

I have used these filters for a couple years now. The house has less dust than when using the cheaper ones. I have allergies, so this is very important to me!! I stock up when they are on sale!

It is a huge and exciting event whenever I change filters in HVAC and these filters never disappoint. I look forward to every event and conscientiously notate the date on a chart affixed next to it.

When you break it down you get a pretty good price for them, however I'm not sure they are measured the same every time; the ones I purchased the time before didn't fit well in the slot on my furance.

I have been using Filtrete furnace filters for years and have been very satisfied with them. Sam's price was very competitive vs my local hardware store.

Allergies have been quite bad lately. Switched to these filters and the difference in my home is incredible. Definitely going to be a regular in my house.

The filters are expensive. Unfortunately, I have carpet and no matter how often I run the sweeper, I will always have dirt/dust. We change our filters monthly, not every three months.

Work well, and love that I can get these delivered in my house to change the filter monthly! We live in a very dusty place, so we need good filters, and we need to change them often. This multipack is a good deal, and convenient for delivery.
