Review on 🔍 High-Grade HDX4CF4 Carbon Filter for Optimal Compatibility (CFS) by Richard Counts

I have used several of these filters over the past year and they seem to work well. These units fit all of my homemade HDX filters that I purchased from Home Depot. I usually change them every 6-8 weeks. The last one I installed failed after 3 weeks (see picture where the filter collapsed) and I emailed the company (Complete Filtration Services, Inc.) with no response after 3 weeks . I tried calling their number but it doesn't work so maybe they went out of business?
