Point of Use (POU) Drinking Water Filter Guide – 3 Must-Know Facts Before Buying a System

One of the biggest boosts for point-of-use drinking water filter systems was the revelation by the NRDC (Natural Resources Defense Council) that “An estimated 25% or more of bottled water is really just tap water in a bottle-sometimes further treated, sometimes not.” Many studies have shown the real figure to be higher than 25%.

This realization is only one of the many strikes against bottled water. People are now thinking twice twice about paying 1,000 times more for something that is not safer than filtered water and is so damaging to the environment.

Choosing the right point-of-use (POU) drinking water filter can be daunting, but if you simply read the 3 facts below, you’ll easily pinpoint the right system. The first thing to know is that POU water filters can be positioned on or in a refrigerator, under your sink or on your countertop. The opposite of POU is point-of-entry (POE). A POE water filtration system is attached to your water line and filters water as it enters the home. These whole house filters provide healthy water to the entire home.

Let’s look at 5 facts that will help you find the best point of use drinking water filter:

1. Price – Point-of-use drinking water filters can produce better than bottled water quality for less than 10 cents a gallon. Many of the best water filter systems have an initial cost that is less than $100.

When looking at prices, consider how often replacement filters have to be replaced. A high quality system should only need replacing about every 6 months and should be able to filter around 10,000 gallons. Watch out for water filter pitchers or small brita spraying out of filter POU faucet-mounted filtration systems that have to be replaced frequently. They appear to be a great price initially, but you can find better POU systems that are less expensive in the long run.

2. POU vs POE
One of the advantages a point of use system has over a point of entry or POE unit is that it removes or reduces contaminants just before you drink the water. This means that P.O.U. systems can eliminate water-borne contaminants like lead or vinyl chloride that could leak into your water from the plumbing. The best option is to use both. While a whole house filter provides many benefits because it sends filtered water to every outlet, a point of use system ensures the safest drinking water.
