Pentek WS-20BB Water Softening Filter Video Transcript

Hey everyone, Tony the Filter Doctor here. Today we’re looking at the Pentek WS-20BB. Now, the WS-20BB is an industry standard size cartridge, approximately 20 inches in length and 4 ½ inches in diameter, which means it’s going to fit into a vast selection of industry standard size filter housings, like for example the one that you see here. Now the WS-20BB is a 20 by 40 mesh; sodium form cation exchange resin. It’s a water softening filter, and it’s designed to remove minerals and it exchanges the minerals with sodium that’s found on the cation resin in this cartridge. Now, it is not a whole house water filter and I’ll explain why. You see, the resin inside of this cartridge has a total capacity of 4,500 grains of hardness. Well, if you have 10 grain per gallon hard water, do the math; you’ll only get 450 gallons of water through this filter. In some houses, that’s only a day or two so it’s a very low capacity filter. It’s great for selective applications, perfect for laboratory settings where low volumes of softened water are necessary for specific purposes. And a great example in a residential setting is for those of you with a humidifier. You may have discovered humidifier dust; it’s when the mineral content of your water precipitates out of the water and ends up in the air and then lands on everything in your home. You can eliminate that or minimize it to some extent by using softened water. Now, your humidifier’s probably only using a gallon or two gallons of water per day, so a filter like this that gives 450 gallons of softened water, is a great choice for that specific application. You might also use it if you were filling a hot tub for a one-time thing, where you just wanted soft water in the hot tub and you didn’t want to have a whole house water softener. So, select applications, low volumes of water or one-time uses up to 450 gallons of water in 10 grain per gallon hard water. Again, this is the Pentek WS-20BB, and I’m your host Tony the Filter Doctor. Thanks for watching.
