I bought 3 packs of these filters. Sam's has the 4 pack at a great price every day but with the extra savings we decided to stock up. These filters are fantastic for anyone that has allergies. Filters out pollen, dust and all kinds of stuff! Be sure to change at least once a month.

The price has gone up, even on sale, but they are still the same high quality filter. Great for those of us with allergies. But you still need to eliminate carpet, drapes, and fabric furniture. All of which collect allergens which are released and float around until they get to the filter. Once I removed those items, I use leather furniture, but some type of fake leather will work as well, and put this filter in, I can sleep at night and breathe through my nose. I'm no longer constantly congested and sneezing inside anymore. I can always go outside to get that, but that's the issue the meds are to solve.

Having a backyard where a German Shepherd and cat love to play and roll in then bring inside made it difficult to find the right filter especially with our GSD lying in front of the air intake. The filter is sturdy and well made. Even though it has to be changed every 3-4 weeks it's well worth the resulting clean air.

Even this filters are expected to be good for 3 months, I have a new singe stage furnace and it stopped heating the house after 3 weeks on this filter, because filter was not letting the air through it. So I had to replace it so fast. This will cost me a lot in filters.

Finally I don't have to worry about filter sizes or when I've changed them last. (There is space on the filter for the date.) An entire year's worth of filters in a single package; wrapped and easy to store. Walmart wants $15 each for these filters. Great quality filters and a great price.

We got the sale ad in the mail and I needed them anyway so I looked on the website and it listed them under instant savings and the ad didn't list the before and after price. I ordered and received them then i was on the app a few days later and saw them showing the $5 saving under the instant savings. I went online to the chat to see if they could honor the price because of the misleading website but was told no.

I live in Texas and use my central air everyday through our hot summers. I always thought these filters were too expensive to try. When SAMs had $10 off, I decided to try them. Wow what a difference from the cheap ones I usually buy. The air is cleaner and things are noticeably less dusty. Definitely worth the price!

These filters are supposed to last up to 3 months and help filter smoke. Being on the West Coast smoke was everywhere the last two years. I plan on buying a smoke filter next, the good one's seem expensive. So between these filters and a UV smoke detector hopefully we will be in good shape this year.

My husband has dust/dander allergies and sneezes daily. While these filters haven’t eliminated his sneezing, they seem to have reduced them. I recommend giving these a try if you’re an allergy sufferer. They can be used for up to 3 months so it’s a win-win!

These filters while on the expensive side yield better overall results. We have a number of cats and despite localized efforts still have hair and dust in the house environment. This is a challenge to environmental allergy. Monthly change, year around, helps and the collect material on the filter is amazing.
