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.

Comes in a pack of 4. Hard ro find size. Got tired of waiting to order elsewhere. Friend came over and easily replaced. I have asthma and know when it is time. Have ordered them before.

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.

Easy to order the ac air filters online using the Sam’s app. Easy check out. Saved money by ordering bulk. Also saved me a trip to the store and free delivery.

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!!

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.

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 ????

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.

Gpod quality great price

Great product
