If you are in the market for a new water purification system, there are some things you may want to consider. If a residential system is what you are looking for, then you need to decide if you are needing point of entry water filtration, point of use water filtration, specialty water filtration, or drinking water filtration. Point of entry water filtration systems normally sit outside of your home or out of view to filter your water, while point of use water filtration systems are designed to be connected to specific household appliances including refrigerator, shower head, bath faucet, and washing machine. Specialty water filtration systems are specially designed for boating, camping and RV's, and drinking water filtration systems are designed to clean drinking water specifically, and give it the best taste possible. Commercial application systems include water softeners, water coolers, and reverse osmosis. Water softening filtration systems reduce the hardness of water and eliminate calcium and magnesium to prevent build up and clogging pipes. Water coolers are designed to keep drinking water cool and refreshing for a commercial or office setting. Reverse Osmosis filtration systems remove unwanted minerals to produce a higher grade of pure water.
