If you found that there are contaminants in your water and that a professional water filter system
will get rid of them, use this guide to help you select the right water filter
system for your home. Household water filters generally fall into one of two categories:
point-of-entry units (whole house water filters), which treat water before it gets distributed
throughout the whole house; and point-of-use units, which include countertop
filters (e.g. filter pitchers), faucet filters, and under sink
units. Some filters use more than one kind of filtration technology.
choosing a filter, make sure it is certified as meeting NSF/ANSI
standards 42 and 53. NSF-certified filters have been independently tested to
show that they can reduce levels of certain pollutants. Those that meet standard 53 are geared toward treating water
for health, not just for aesthetic qualities.
Consult the list below to determine which type of filtering system will remove the contaminants in your water:
filter will give you good performance over the long term unless it
receives regular maintenance. As contaminants build up, a filter can not
only become less effective, but may actually make your water worse, by
starting to release harmful bacteria or chemicals back into your
filtered water. To keep your filter working properly, follow the
manufacturer's maintenance directions. Most water filters only require a
periodic water filter cartridge change. We offer annual replacement auto-ship programs for most of our water filter products. Before buying any water treatment system,
compare not only filter prices, but also operating and maintenance costs
for the different units.
