Filtrete 20x24x1, AC Furnace Air Filter, MPR 1900, Healthy Living Ultimate Allergen, 6-Pack (exact dimensions 19.81 x 23.81 x 0.78)

I feel these filters really help clean the air. I write the date I install them and the date I want to replace them on the filter so I can always know where I am in the cycle. I replace them every three months unless my dog is shedding and then I replace them more often.

These filters come in a great box that I would have thought a label could have been attached to the box, but instead this box of 6 24 in by 1 in filters arrived in a boxes that was 6 ft by 4 ft how crazy is that with the cost of shipping, this box was all smashed because it was basically empty, this is crazy a waste of money and materials

When mountain cedar is > 25k, these are the only filters our family trusts. Genuine filter, great quality.

Order these often for my home.

Noticeably less dust in living area.

Just as expected, works great.

i recently purchased these filters and it does an awesome job for people who have bad allergies. I would highly recommend this to anyone and everyone that i know.

It was the right size and so far so good

They catch everything in the air. As a result I have to change them often But I and my Sheltie have allergies and the difference the filters make is noticeable

Works well for our dusty area.
