The Honeywell 16x25x4 Ultra air filter replaced an Electrostatic Air filter that wasn't living up to all the hype that came with it. Before installing the Honeywell unit I had my ducts professionally cleaned,I could not believe the amount of junk that came out of my system. So far the new Honeywell Ultra is doing a fine job, there is a noticeable difference in the air we breath and no dust anywhere. I will inspect the filter on a monthly basis and replace as needed. So far, so good.
