Next to pitcher filters, faucet (or tap) water filters are an economical, quick and an
easy way to get filtered water in the home and a convenient way to replace bottled
water. Just attach the filter unit to a kitchen faucet
and enjoy filtered water directly from the tap. Installation is simple and usually no
plumbing or tools are required. There are several kitchen faucet water filter brands on the
market with some even having 5-stage filtration capabilities.
The advantages of a faucet filter are low cost, space-saving, easy access, quick and easy to
install and use, attractive designs (some with chrome look) and of course convenience.
Models with multi-stage filtration can effectively reduce hundreds of contaminants from tap
In the most designs, a turn of the switch is all it takes to get filtered or unfiltered
water. Clean filtered water comes out from the bottom of the filter unit for drinking.
Unfiltered water flows through your regular faucet as before for washing or when filtered
water isn't required.

Most faucet filters have been tested and certified for chlorine reduction and improved water
taste/odor. In most models, Granular Activated Carbon (GAC) within the filter cartridge is
used as the basic filtration medium which reduces bad tastes, odors, chlorine, pesticides
and other chemicals that are often linked to cancer risks. The flow rate of the filtered
water depends on the faucet water pressure which in some cases could be slow. However, the
resulting fresher tasting healthier water is worth the wait.
Some advanced models like the
Chrystal Quest CQE-0501 utilize a five stage filtration process. In
Stage 1, water passes through a pre-filter one-micron filter pad which reduces suspended
particles such as silt, sediment, cyst, sand, rust, dirt, and other un-dissolved matter. In
Stage 2, water passes through Granulated Activated Carbon (GAC), which reduces chlorine, bad
tastes and odors, pesticides and chemicals like benzene, TCE, toxaphene. In Stage 3, Ion
Exchange Resin reduces heavy metals such as lead, copper, aluminum, and water hardness (pH).
In Stage 4, water passes through a combination of KDF 55 and KDF 85 to reduce iron, mercury,
copper, nickel, chromium, cadmium, aluminum, lead, other dissolved metals and hydrogen
sulfide, and prevents growth of bacteria, algae, fungi, scale, and other microrganisms. In
Stage 5, water passes through a post-filter one-micron filter pad which again reduces any
remaining suspended particles or other un-dissolved matter.
As another option, the next generation
PUR RF-9999 replacement cartridge (which fits all the PUR faucet filter
systems) now offer the MineralClear™ filter which additionally filters the water over
natural minerals for a crisp, refreshing taste. The premium carbon filter is certified to
reduce chlorine (taste and odor) and many contaminants including 99% of lead and microbial
cysts. It also helps reduce trace levels of pharmaceuticals.
Good Basic Filtration
In most faucet filters, the simple filter cartridge within the faucet is based on carbon
filtration, which provides chlorine removal and sediment reduction. However as in pitcher
filters, it is not a complex filter system and provides only basic filtration. A faucet
filter does a better job than a pitcher filter in reducing chlorine, taste/odors, particulates and contaminants like copper, lead, mercury, zinc
and microrganisms but most would have difficulty with complex chemicals like volatile organic compounds (VOC's) or
A faucet filter also requires regular filter changes. The most common styles use an
activated carbon filter cartridge which needs to be changed regularly (typically from 3-12
months depending on the manufacturer and model).
However, a faucet filter is a low cost investment and a convenient, easy solution in order to
have healthier, better tasting water.
