Good filter. Sturdy. Helps with family members allergies and asthma. Good product for a good price! Catches everything we need on a daily basis. We did upgrade just for the summer last years when dealing with wildfire smoke and the 2.5 particulate. Then back to these!

After using these for six years, the inside of my AC unit is almost as clean as when it was installed.

They fit the opening OK and seem to work fine. I can't tell by using them if they do or do not capture allergens, bacteria and viruses.

Great value! We need the extra allergen filtering provided by these filters to help with family allergies. These do not dissapppint.

the filters work very well act "catching" dust and hair and very economical since we only replace them every 3 months.

Excellent filter! You will have to change it out more often, but I feel it is worth it. And at this price, the price per filter is excellent!

I have been using these filters for many years. Sam's Club is the most economical way to purchase them using Instant Savings.

Honestly I've been using these for years. The filters are work great! Love the ability to buy in bulk.

It is awesome way to take care of unwanted pollution, germs, and viruses. Change it, as suggested, let it do its function, feel the results.

I've been buying Filtrete filters from Sam's for a few years, but this is a different version than what I usually buy. I like that it feels sturdy, but it's just too restrictive for our system. Hoping they bring back the slightly lower MERV rating filter that I had been buying previously.
