A whole house water filter treats all the water flowing into every area of your home, ensuring that everything from the faucet, to laundry, to the shower is filtered. Clean water will be found everywhere you need it. A whole home water filtration system classifies as just about any water purifier, softener or carbon filter. The long-term benefit is that a water filter system for your entire home will remove all contaminants that come through your plumbing system. Whether for cleaner water to drink or for your everyday use, having that purification will leave you feeling fresher.
