Water Filters

If you're looking to improve the aesthetic qualities of your water, such as hardness, odor and taste, you may consider purchasing a water filter.

Before purchasing a filter, it is important to weigh the pros and cons of each type.

Types of Water Filters
  Description Pros Cons

Activated Carbon Filters

 

 

Activated carbon filters attract and hold certain chemicals as water passes through them. They are available in carafe units, faucet-mounted filters and models mounted beneath the sink.

Reduces chlorine odor and taste; can be inexpensive

 

 

Doesn't remove minerals associated with hardness; can require frequent filter changes; does not remove microbes

 

Reverse-Osmosis Filters

 

 

 

These systems use both a traditional (usually carbon) filter and a cellophane-like membrane to remove most organic and inorganic compounds. This is the only type of filter that will remove calcium and magnesium, the minerals that cause hard water. These filters are usually installed below the kitchen sink.

Removes minerals that cause hardness; highly effective

 

 

 

More expensive; may require a plumber; requires more storage space; many units waste water

The Water Authority doesn't recommend any particular brand or model. However, we provide Consumer ReportsŪ ratings of several brands and types of water filtration systems. Request a copy of the report.
