Water filters can improve the smell and taste of water by reducing sediment, pollutants and other contaminants. Adding a system to filter your water doesn't have to require a major renovation or big investment of time and money. There are many systems from which to choose, from economical pitcher filters to more comprehensive reverse osmosis units. This guide will explain the different types of systems available and how to determine which will meet your individual needs, so you can feel confident you're selecting the right filter system for your home.
Types of Filtration Systems
Water filter
devices can be installed in a number of ways. The most basic filters attach to
a carafe or pitcher while more elaborate point-of use and whole house systems
provide filtration for a greater volume of water. A household pre-filtration
system is the simplest and most comprehensive solution for filtered water
throughout your home. However, when this isn't feasible, various types of
filtration systems can be used to create a cost effective solution. Consult
the table below to learn more about options for filtration systems.

Match the System to Your Need
While
municipal water has been thoroughly cleaned and tested to meet Environmental
Protection Agency standards, even water that meets government standards can
have unpleasant smells, tastes, or trace amounts of bacteria, chemicals or
gritty sediment. Well water may contain harmful chemicals, nitrates and
coliform bacteria and have unpleasant tastes and odors.
Identify the problems with your water you want to correct then select the system that provides the best solution by referring to the table below.

Features to Consider
NSF Ratings
Filters with NSF/ANSI standard 53
certification have been independently tested to show that they can reduce
levels of certain pollutants under specified conditions.
Ultraviolet Light
Kill viruses and bacteria in water, but they
don't filter out chemicals. They can be used in conjunction with carbon
filters.
Filter Change Indicator
Look for a water filter that has a
flashing light or color-changing indicator that lets you know when it’s time
for a new filter.
