Simple Guide to Home Water Filters
Home water filters are most often used to reduce chemical
exposure from municipally treated water supplies. Most water
filters for household use employ an activated carbon media which
reduces many impurities including chlorine, lead, mercury, cysts,
pesticides and other impurities. Here is a simple guide to some of the
most common household water filters on the market today.
or carafes with built in water filters provide cold, filtered water.
Simply refill the pitcher through the top, and the water flows down
through a filter into the main canister at the bottom. There are many
different styles of pitchers that can fit neatly into your fridge or on
your tabletop. These typically use a carbon filter media that reduces
bad taste and odor caused by chemicals like chlorine and its
byproducts, along with lead, mercury, sediment and dirt. Some pitcher
water filters may also remove microbiological cysts and agricultural
and industrial pollutants. The filters should be changed every 2-3
months, and many pitchers come with an electronic filter life indicator
that lets you know when it's time to change the filter. One
disadvantage of pitcher filters is that they hold limited quantities of
water and are therefore best used in smaller households.
How to Buy a Water Pitcher Filter
water filters attach directly to your sink's faucet. These allow you to
switch back and forth between unfiltered and filtered water for cooking
and drinking, extending the life of your filter. Many faucet filters
also have an electronic filter life indicator to let you know when it's
time to change the filter. Faucet filters will reduce many of the same
contaminants as pitcher filters. The advantage to these is that they
don't take up as much space as other filters do. But if you like your
water ice cold without the cubes, you may be better off with a pitcher
filter - at least during the summer months.
How to Buy a Faucet Water Filter
top filters also fit directly onto the faucet. They take up more
counter space than faucet mount filters, as they sit directly on your
counter top. However, they allow you to filter larger quantities of
water without modifying any plumbing, and they are less likely to clog
than pitcher or faucet filters. Countertop filters remove many of the
same impurities as pitcher and faucet mount filters, providing you with
fresh, clean drinking water straight from your tap.
How to Buy a Countertop Water Filter
water filters require some minor plumbing modifications to install.
These fit directly inside the cabinet under a kitchen sink and come
with a separate dispenser that fits through a drilled hole in
or countertop. Like countertop filters, these are also able to filter
large quantities of water.

osmosis filter uses household pressure to force water through a
semi-permeable membrane. These filters reduce a large number of
contaminants including pathogens, dissolved solids and volatile organic
compounds. These are some of the most effective water filters on the
market. However, they are significantly more expensive, and their
filtration process produces large amounts of wastewater.
How To Buy a Reverse Osmosis Water Filter
water filters are installed directly into your water line and provide
filtered water throughout your whole house. These are beneficial for
homes with very poor water quality, or very hard water that needs
filtering for uses other than drinking or cooking. These reduce
sediment, rust, and in some cases, chlorine. However, since they are
not designed to remove many other contaminants (i.e. microbiological
cysts or VOC's) they will likely need to be used in combination with
other filters for clean drinking water. Fortunately, they are
inexpensive and the cartridges have a long filter life.
How to Buy a Whole House Water Filter
refrigerator water filter is a space-saving filter option if you desire
cold purified water and ice straight from the fridge, but don't have
room inside for a pitcher. There are two types: push-in filters install
directly into your refrigerator's water filter compartment; inline
filters are attached to your house's water supply line on one side and
to your refrigerator's water line on the other.
How to Buy a Refrigerator Water Filter
water filters attach directly to your shower head. These reduce
chlorine and may aid in preventing dry skin and respiratory problems
caused by prolonged chlorine exposure and inhalation. Some shower
filters come with their own adjustable shower heads, giving you several
different options for water flow and pressure.
