Great product. It does what it says it's supposed to do. I change them every 3 months. I had my furnace looked up and they said it's one of the cleanest they've seen in a long time.

We found not many places carry filter size we need for new home. We can get excellent filters on sale price right here and delivered to home at no extra charge.

Quality product that does the job our HVac person told us a good quality filter changed monthly will extend the life of our furnace/ac. And it certainly does.

There are cheaper filters but these are of excellent quality. One of these filters lasts us about three months. We have a lot of agricultural dirt & grain dust in the area in which we live. The extra filtration qualities are worth the price.

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.

These filters catch the dust and pollen that others let through. I am very pleased with these filters, they are not as inexpensive as the others but do a better job., NO MORE SNEEZING.

Hi quality filter that works great. We change the filters every three months, seems about right here in the desert southwest. Great price at Sam's for a 4-pack, and usually in stock when we need to restock.

This model filter is the best. It's a full boxed filter so it holds up well in a strong blowing ac. Doesn't cave in like lot of other filters. And filters good also. Always purchase these. Good price for four pack.

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.

We have tried different brands because we switch them often and they are a little pricey but they are so worth it. I see the difference in the air quality in my home.
