Furnace filters can be pricey but they are a necessity. The more frequently you change them the better for your air quality. I live on a heavily wooded lot so I need the furnace to do a little extra because of dry leaves and dirt that add to the air quality. These filters seem to do their job. Not the most expensive but not some cheap off brand. Filtrate is a good, known brand.

Hoping these filters are providing some much cleaner air than what has been outside with all the wildfire smoke/haze...would not use any other filters and make sure to change them every 3 months...glad Sam's carries them and free shipping with Plus membership! They are not cheap but think they are worth it!

These filters at MERV 12 have more pleats than those of a lesser MERV value and therefore last longer in your unit, in spite of filtering the air better. Any air pressure increase is minimal and not a concern. As a retired mechanical engineer with HVAC experience, I believe that MERV 12 gives the best combination of filtration, pressure drop, and filter life. I live in Texas and my units run nearly all year, so I replace my 4" wide filters every 6 to 8 months.

I and my HVAC service tech love these long lasting hard working furnace filers. I recently put in a new system (replaced the 23 year old furnace and A/C units) and have already obtained the correct size filter for it to be put into use in about 6 months time!

First time I ordered a Filtrete 20x25x4 Air Filter. I was excited to get this because it was a rated MERV 12. The problem is that this was too big even though my current filter (and all the other ones through the years) was a 20x25x4. It would not fit. I ended up tearing up the packaging around the filter to get it to fit. Terrible. When I put this on top of my other filter it was not same dimension.

This was a replacement filter and was exactly what I needed.

Just wat I needed it

Great product

I’m sure they were good filters but the wrong size. Sams club took them back no questions asked.

We ordered the set and it came in damaged. Got with customer service to get a replacement, and the replacement arrived damaged as well
