Review on Aprilaire 501 Replacment Electronic Purifier Appliances by Deejay Devarashetty

Model 5000 Air Filter did the job. The electronic part of the filter worked fantastic charged dust particles stuck to the metal mesh. I had to take a brush and brush away electrically charged dust from the screen's metal frame. I bought a Merv 16 filter because of a virus, next time I will go back to the Merv 12 filter and see if there is a noticeable difference. The Aprilaire filter box has detailed step-by-step instructions printed on the filter boxes. If you understand what you're reading and look at the charts, changing the filter shouldn't be a problem.
