There was no issues with the sizing and fits perfectly, especially the 4in width. Item came good condition and looks quality made. It catches the dust and whatever dirt on there well by the time I changed it. This came in one only but for the price paid for it, felt got good value from it. Don't know what more to say.

Fits and works as intended!

[This review was collected as part of a promotion.] The filters are the ones that my AC company recommended.  Walmart was selling them at a REDICULOUS price.

When I first started using these filters I immediately noticed a reduction of dust in the house. I went from having to dust once a week to about once a month or longer depending on the room. If you suffer allergies from dust, pet hair etc., you will notice a significant improvement. We use Filtrete Allergen Defense 1200 MPR.

Gets the dust

filtrete.com

It was in a perfect-appearing undented box plenty big enough with plenty of bubble wrap, but it was smashed to smithereens inside.  I worked out the dents and was able to make it work anyway.  With 5 cats, remodeling construction, and living on a dusty dirt road, this filter does great for 1 to 2 months.

Good filter!  clears the air of cat hair!

Too restrictive does not allow enough air flow. My 5 ton unit is sized correctly for my home. My return is 1024 sq in Unit struggled to cool with these in higher temperatures. Unit is less then a year old as soon as we put a less restrictive filter in the air flow was better and unit was quieter.

Too restrictive.

The image on the website says there are FOUR filters in each package. In truth, there is only ONE.

Deceptive advertising

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.

Size Not As Advertised

Do not buy from seller, it's a fake product and no where on the filter it says MERV 11 as they show in their pictures.

Fake product

These do NOT fit. The card board case wrinkles when inserted, THEN you get about half way and cannot remove it due to the cardboard wrinkled up and it locks the filter in place about half way and you must rip the cardboard packaging to get it out to remove and try re-inserting it. (Yeah the system was turned off while doing this, no need to post telling me to try turning off the unit forst.)
