Perfect airflow and perfect size

Solid, good fit, excellent filtration.

These filters are very solid, fit tight in the fikter housing, and don't seem to reduce air flow like others I've tried. I used the MERV 11s because they stop plenty of airborne dust and pollen.

Good filters, decent price

Good filters for the price, check MERV ratings for comparison.

Both filters were badly damaged

Cheaper than Honeywell

Good quality filter but does not fit as tightly as the Honeywell so I put two strips of duct tape lengthwise across bottom of filter works great.

Furnace filter

What I was looking for

The filter was compressed in 3 areas. I managed to use it.

AC Filter

Good product

Fine filter

It's a filter - it works 🙂

Fits perfect

Fits perfect

Glad ACE carries it

It's the only one that truly fits our system. Measure carefully

Good product but too large for my system

I expect these are a good product, but the width is actually a little greater than 4 inches, and did not fit my unit. ACE graciously exchanged them for a different brand which is a little smaller than 4 inches - even though both items are listed as 20x25x4 :)

So far the air filter works well. However the time frame in which we have to review that product isn't really a good time frame to test this product out. If there was more time we could see how long it lasts compared to other air filters.

Easy to install and good quality. They fit perfect with no gap, which makes a good value for the air filtration. Effective product! I highly recommend them.

I use the merv 4 version but decided to give this one a try. It works quite well! My heater does turn off on more frequently. Besides that, I see less dust to clean. My cats allergies are happy with the temp switch as is my dog.

I have four dogs who shed ALOT so I need a good air filter. This one works great and I really feel like the air quality in my home is so much better. I will buy these in the future

it fits

does the job

My filter was dirty and this was a much needed product to receive! The heating and cooling in my house has been working much more efficiently since changing it to this filter!

Wrong size filter delivered- TWICE

DO NOT ORDER THIS… the item description is for a 20x25x4 filter. THAT IS NOT WHAT IS DELIVERED. I have ordered twice thinking there was just a simple mix-up on the first order. Each time 20x25x5 filters have arrived. The bill of lading has the right order, but that is not what is in the box. Something is wrong in the system!

I did not get a chance to take a picture before my husband put this in. However he advised it is sturdy and seems like it will work well. Some filters in the past seem so flimsy and the bow up when putting them in. This one held its shape. So far no issues and it’s working great.
