Looking for a water treatment device, but confused about how to ensure you are selecting the right one? Here are three tips to help make the process of selecting a home water treatment system easier.
Identify your main water quality concerns. Does the water taste funny or have an unusual odor? Is the water discolored or leaving scale deposits? Or, did a water test or community water quality report indicate the water contained high amounts of any contaminants?
Listed here are five common technologies and their potential uses:
Filter medias - May reduce chemicals, some metals, parasites and, sediment.
Cation exchange softener - Help reduce hard water; some also reduce barium and radium.
Distillers - Help reduce heavy metals, minerals, and non-volatile chemicals.
Reverse osmosis - May reduce some metals, minerals, and parasites; post-filter may also reduce some chemicals.
Ultraviolet disinfection - Help protect against bacteria and viruses.
Pour through - Water drips via gravity through a filter. Pros: no installation required. Cons: frequent filter changes.
Faucet mount - Mounts on kitchen faucet. Uses diverter to direct water through filter. Pros: easy to install. Cons: frequent filter changes.
Counter-top connected to sink faucet - Filter connects to existing sink faucet via a hose/tubing. Pros: easy to install and longer filter life. Cons: uses up counter space.
Plumbed-in to separate tap - Installs under a sink; filtered water is usually dispensed through an auxiliary faucet. Pros: longer filter life. Cons: may require professional installation.
Point of entry - Installs where the water line enters home. Pros: treats all water entering the home. Cons: may require professional installation.
