Better filtration is the first step in improving Indoor Air Quality. Pleated Panel Filters outperform ordinary furnace filters with higher efficiency and lower pressure drop allowing air-handling systems to stay cleaner and operate more efficiently. We achieve this with 100% synthetic electrostatically charged gradient density media, optimum pleat spacing and high initial and sustained efficiency, high dust holding capacity and very low pressure drop. The media is resistant to a wide range of chemicals, does not absorb moisture and will not support microbial growth.

I need a real 20X20X4
The actual size is not 20X20X4 and it is not a tight fit like it requires.

I use these filters in our AC unit, and I had a hard time finding the right size to fit for a 4X4, but these fit perfectly and seem to work great. I just bought them, so I'm not positive about long term quality, but they appear to be in very good shape so far

I love these filters without question! They are the best I've found in the price that offer perfect air cleaning. My son has allergies and since we've used these filters, he has not had as many problems. I recommend these filters and Discount Filter to everyone.

The main ingredient in almost all water filters is activated carbon, which is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for absorption of chemicals and impurities.
