Glasfloss 16 x 25 x 4 MERV 10 Furnace Filter (6 Pack)

These filters work well without restricting airflow through our furnace. Going on 7 years using these with replacement every 3 months.

These filters are perfect for my furnace. When I bought a new furnace a few years back the installer looked at the fancy name brand filters I had been getting from Target and suggested I stop using them. He said those filters work so well that they make it hard for air to flow through leading to furnace damage over time. He recommended these to me so given the price I pay for this multi-pack plus the convenience of not having to run to the store every three months once I realize it's time to replace, I will never buy another type again.

I needed filters that were 4" thick or less. It seems like a lot of manufacturers sell 4" filters that are actually a little thicker. I have a tight furnace filter spot and the standard filters that are actually about 4.25" thick just won't fit. These filters are perfect and are just narrower than 4" making them install easily. Filters appear to be just as good of quality as I would buy at a big box store, but these are a fraction of the price.

My HVAC technician told me to go with a lower MERV rating filter as they’re less restrictive and will increase airflow throughout the house….so I grabbed this 4 pack at a pretty good price. The filters seem a little flimsy, but I think that they’re working ok..

This is the second time I have purchased these filters. They are a great value for the money. So nice to have them so I don’t have to run to the store when I need one.

The cost of a single filter for our furnace at other stores basically pays for half of the order. These are just just as good as the name brand ones. So i get a 6 month supply for less $.…

This is the best price I can find these anywhere. They’re all in one big box and I wish they were individually wrapped so the others don’t get dirty while I use one, but they last a while

Definitely a good value since the big box stores and local dealers charge at least twice as much. Last just as long as the more expensive versions. Will purchase again.
