20" x 4.5" Filter Overview Video Transcript

Hey everyone, Tony the Filter Doctor here. Today we’re looking at the 20 inch by 4 ½ inch industry standard size filter category. Now, all of the filter cartridges that you see here in front of me are approximately 20 inches in length by 4 ½ inches in diameter, which means they’re going to fit into a vast selection of industry standard size filter housings, like the ones you see here. But there are also many other filter housings manufactured by dozens of manufacturers that receive the same size filter cartridges. It is a very popular industry standard size. And as I indicated there are dozens of manufacturers producing thousands of cartridges and hundreds of filter housings all in this industry standard size category. What that means for you is this category provides you with a great many options and a great deal of flexibility when dealing with your particular water problem. Nearly every water problem that exists can be dealt with by a filter cartridge or combination of filter cartridges from this industry standard size category. There are pleated cellulose, there are pleated polyester, polypropylene spun, polypropylene string wound, carbon block, granular activated carbon, KDF/carbon combo filters, and a whole list of unique specialty filters that are designed for your unique circumstances. Whatever problem you have with your water can be dealt with by this size category. Now, in my opinion this size category is the best possible choice for whole house, point of entry filter applications. You could go wrong installing too small a filter housing; like for example, a 10 by 2 ½ filter housing in a whole house application. But you can’t go wrong with these large housings and these filter cartridges with their massive surface area and the large amount of filter media that they provide. They will give you excellent flow rates, extremely low or no pressure loss at all, and long intervals between filter cartridges; which basically means, long filter life and very little maintenance work for you. It’s the best choice to filter the entire volume of water to your entire home. There’s no need to have filters at every point of use when you have one big filter at the point of entry, and that’s what this size category is designed for. Again, this is the 20 inch by 4 ½ inch industry standard size filter category, and I’m your host Tony the Filter Doctor. Thanks for watching.
