3M DP01DC-4 Filtrete Ultra Allergen Healthy Living Electrostatic High-Performance Air Filter, 16-inches x 25-inches x 4-inches

Filter size is not 25 x 16 x 4. It is 25 x 16 x 4.5. It doesn't fit at all.

It fits perfect

Have used these filters in the past and found them to be quite good. I don't use them for the year that they claim you can. I swap them out between 6 and 9 months depending on how dirty they look. The delivery time from my latest purchase took 2 days longer than promised.

No problems yet

This is the allergy filter for my furnace, it helps keep this dust levels low in my house which is imperative for allergies and also means less housework. I put one of these in my furnace every fall.

Does a nice job

great price keeps the dust down now that cold weather is here

The box was damaged and one corner of the filter was crushed. I'm still able to use it but I expect it to be in perfect shape when it

I buy this size Filtrette filter all the time, but this one is actually the width of one marketed as "slim profile 5-in" in some stores ...just a few millimeters too wide for my 4" case. Shame cause it is MERV12, according to the box. The filter wrapping was also slightly damaged, but i do not think significantly enough to have damaged the product beneath. I would definitely try this if my box was at least 12 cm wide.

Great filter, but be very careful as the dimensions are greater than 4" wide. They are 4 and 5/16". Unfortunately this did make a difference for our furnace and it was too tight.

The product is just what we were looking for, however we were not pleased at having to go pick it up at a depot rather than having it delivered to our door. If we wanted to go out and pick it up we could have gone to a big box store!

It fits good! The price is cheaper compare to other stores and hard to find them. Will recommend Filtrete definitely!
