19 7/8 x 21 1/2 x 1 Carrier Replacement MERV 10 Pleated Air Filters by Glasfloss. Box of 6

it is good filter

Arrived intact and exactly what was ordered.

This is the same filter my A/C & Heating service company switched to for my Carrier A/C system some six months ago. The system is just over three years old; until about a year or so ago, I could no quality filter of this size for the unit, except a flimsy model. I, therefore, used custom-made filters with a high hypoallergenic rating, but they were denser and reduced airflow and no doubt made the A/C unit work harder. After installing the first filter from this Glassfloss package, in accordance with the airflow arrows on the filter, I noticed a fairly loud whistling noise--one which I have never heard before. I assume this noise is caused by airflow moving across the metal screen on the filter. I do wonder, however, if this will affect the filter's performance and whether or not this is a one-off. None of the filters previously installed in the air handler by the A/C service company made this noise. If the next filter from this package makes this noise when installed, I will update this review, as the whistling noise is annoying, especially when I am working in my garage.

Could not find this size at the location hardware store. These are correct and cheaper then buying from a contractor.

Received on time and in good condition at a reasonable price. It saved me about $10.00 in fuel costs.

Good value for the money

These filters came with my new HVAC install, so I was happy to be able to locate the exact filters for my system.

I use these in my furnace, my daughter has vary bad allergies, and they have made a big difference. And i can see it when I change the filter. The filter will be covers in dust and the inside of my furnace looks brand new and it is over year old
