Water Filtration Systems

Water filtration systems come in two types: Point of Use (POU) and Point of Entry (POE). 

Point of use systems are generally installed at the kitchen or bathroom sink. The point of use systems can have one, two or threefilter housings with each housing containing an individual filter with a system flow rate of approximately 1/2 – 1 gallon perminute. A point of use system can be installed on the counter top or under counter.

Point of entry systems are installed where the main water line enters the home. The point of entry system is commonly referred to as a whole house system, as the filtration it offers treats the water for the entire home. Like a point of use system, the point of entry allows for one, two or three filter housing with a system flow rate of 5 -20 gallon per minute.

A wide variety of filters manufactured to treat a wide range of water related contaminants are available for both the point of use and the point of entry systems.

Under counter filtration systems require them to be plumbed to the main cold water supply.
