Size Not As Advertised
on December 7, 2025
Posted by: CWDJR
The actual dimensions of the 16 X 25 X 4 are advertised as 15.88 in x 24.56 in x 4.31 in. However, the actual depth of the filter is only 15.44 (15 7/16) in as seen printed on the filter. This leaves a gap on top of the filter that the air can circumvent rendering the filter fairly worthless.

Better Air Filters

We have been using Filtrete Better Air filters for sixteen years. They provide the best filtration of any product that we have tried. We also save some money, since we don't have to use the Best Filters. If there is a downside, it is that the filter is effective for only about one month rather than for the longer period shown on the wrapper. An additional plus is that the filters come in the non-standard size required by our system, so we don't have to alter them or jam them in.
I would recommend this to a friend!

Filtrete Filter Micro Allergen Reduction Filter

I moved into an adult community where they put the furnace in the attic. The only way to get to the furnace to change the air filters, is to climb up drop down steps that are in the garage. This is extremely difficult for my husband and I to do. My son has created a part time job by changing the air filters for over 20 families who are not able to climb up these steep steps. He uses the Filtrete 3 month filters. It is totally amazing what these filters look like when he removes them. The filter is absolutely covered with such thick dust and G-d knows what else! I mark it on my calendar when to change the filters, and my son has everyone on an automatic visit from him within 90 days.Your filter performs better than any other filter that we have tried.

Filters well.

We use this as an auxiliary to an electronic air filter and notice it gets out dirt and particles the other filter misses. I can tell when it needs to be replaced by the dust in the air.

Suitable filter

The filter has enough rigidity to withstand the strong blower from my AC unit without deforming.
