I searched high and low for the right size of filter my house is older so it is harder to come by but these were wonderful! Great quality, the airflow is wonderful as well! Best value for the price as the filter functions just as it says and protects your house! My household noticed a difference within 24 hours! We do have a small dog and it works great with her!

My ac air filter has a uncomment size which is 17x20x1. I can't find this size anywhere in the local store. I am glad I found it online and it fits perfectly. This filter's quality is awesome because I can feel the difference without it. it traps most of airborne particles as small as microns, including dust, pollen, pet dander, mold spores, and even some bacteria. Within a week of installing it, I noticed a dramatic difference: less dust on my shelves and furniture, no more sneezing fits when the AC kicks on, and a noticeable reduction in pet odors. Read more

These were good but they sent me the wrong size they went in there, but it was awful tight. I would rather have the size I told him 20 x 25 x 4 1/4. They sent me 20 x 25 x 5. Read more
