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.

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.

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.

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.

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.

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 love these filters. I can feel very confident knowing that all pollutants and contaminants are being filtered out. The added bonus I wasn't expecting was having less dust in my home.

Been buying these filters for a while, they work perfectly in our house and really help eliminate odors, dust and other issues. Price is great when on sale and we stock up on them. Would definitely recommend them.

The best when it comes to necessary for the home. Living in Florida where we have lots of allergens, and especially during dry seasons, we all want the best filter available for our homes.
