'These seem to be working well this summer. I bought them as a trial from 2800 after the HVAC tech suggested an easier way for the air to flow. So far I really can’t tell a difference except it’s better on my cash flow.

Nice filters. We buy them when they are on sale. The multi pack is a better deal than buying them individually. They work great! We change them monthly during high allergy times. Can go longer at other times.

Fair price and high filtration. We change the filter at the start of every new season so four will last one year. They are well made and indeed do the job.

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.

These filters are bodacious! I breathe better than ever now. I can feel the air pumping through. Clean, fresh, delightful and pure! Other air filters are not as good. These are best that can be!

this is the greatest value on a four pack. Just buying one of these in the store is around $18. Great price this was for 39.98 for 4. Best ever filter

The filters are good and was cost effective when I was shopping around! I gave it a 4 star because there was a bug on one of them when I opened it! But other than that, what I needed it and good deal for the price!

Very inconsistent in size. The actual dimensions are bigger for a filter in the pack, while a different filter has correct size to fit the vent opening. Very frustrating!!

Prior to using this filter the hardwood floor beneath our bed always became covered with lint/dust from the heat register. That's no longer the case with this filter.

I have to buy filters and replace once every couple of months due to my dogs and this is the cheapest place to find them. They are almost $20 any where else.
