Pentek GAC-20 Carbon Filter Video Transcript

Hey everyone, Tony the Filter Doctor here. Today we’re looking at the Pentek GAC-20. This is an industry standard size cartridge, approximately 20 inches long by 2 ½ inches in diameter, which means it’s going to fit into a vast selection of industry standard size filter housings, like the one you see here. Now, the GAC-20 is a 20 micron, granular activated carbon, axial flow filter. Now by axial flow we know that the water enters the bottom through these slots then rises through the entire bed of media and exits at the top. Now, this axial flow design is great for contact time with the water, which equals greater contaminant removal. However, it also causes significant pressure loss and flow restriction; making this filter a bad choice for whole house filtration. However, you could use it as a drinking water filter. Now I know that a filter housing like this will probably not install underneath the kitchen sink, but there’s no reason why you can’t install this in another location and then use this filter and run the water line to your drinking water faucet. It’s going to create a scenario where you have a very long lasting filter requiring significantly less maintenance. In fact, Pentek internal testing certifies the GAC-20 to be good for 10,000 gallons of chlorine reduction. And, of course, granular activated carbon removes a long list of organic and inorganic contaminants that you simply don’t want in your drinking water. Again, this is the Pentek GAC-20, and I’m your host Tony the Filter Doctor. Thanks for watching.
