Comparing Different Water Filters for Your Home

various home water filters

Water quality can be greatly affected by the water filters in your home. With that being said, you may want to consider different water filters to bring water quality up to your standards. If you get your water from a municipal facility, it likely meets federal and local criteria for purity. However, while those water quality standards may be high enough for the agencies that set them, do they meet your standards for the health of your family? For example, the amount of chlorine in your drinking water may strictly comply with government specs yet still be higher than you’re personally comfortable with, given some research about possible long-term health effects of chlorine byproducts. Maybe the taste and visual appearance of your water simply do not meet your expectations—though it doesn’t present any sort of health hazard.

Water filters for the home can be generally divided into two types:

  • Whole house filters install in your main water line at the point where it enters the house. These may be multiple inline filters of different types that treat all the water distributed throughout your home to every fixture.
  • Point-of-use filters are typically installed at an individual fixture such as a kitchen sink. Other fixtures in the house may still dispense unfiltered water.

Whole house filters are usually an array of several inline filters. A standard pre-filter may contain a basic mechanical filter element that removes common sediment such as sand and grit that causes cloudiness and other aesthetic issues. It may also remove high levels of naturally occurring iron that discolors water and affects taste.  Another type of canister filter in a whole-house system is an activated carbon filter to remove a variety of chemicals — the most common being chlorine and pesticides.  A whole house array may also include a sub-micron filter to remove toxic microorganisms, like Giardia and cryptosporidium, that are resistant to the sterilizing effects of chlorine. A UV light unit incorporated in the whole house filtration system can provide further protection against pathogens and viruses by exposing water to disinfecting ultraviolet light rays.

Point-of-use filters are usually under-sink units that utilize reverse osmosis to purify water at that specific fixture only. The device passes water through a membrane, utilizing pressure to extract chemicals and microorganisms. Reverse osmosis is a highly efficient process and water filtered through these units is generally the same purity as commercially-available bottled water.
