The sole purpose of a water purifier of any kind is to remove contaminants from water the flows into a home that is to be used for drinking or cooking purposes. Although they all serve the same basic function, there are in fact a number of different types of water purifier that can be used in a home, everything from the simplest faucet filter to whole home systems that purify the water as it enters the home.

What Contaminants Might Be in my Drinking Water?

We would all love to think that in the 21st century, with all technology that exists, that the water that flows into our homes is nice and pure. Sadly that is really not the case. Whether your water comes from a well or from a water treatment plant it may contain disease-causing pathogens, waste from landfills and septic systems, toxins from the careless disposal of hazardous household products, residues of agricultural chemicals that leach into water through the soil. Not a very appetizing thought at all is it?

Different homes may have different contamination problems and, somewhat confusingly, different water purifiers are designed to remove different contaminants. In order to ensure that you are making the right choice when it comes to buying a water purifier it may help to have your home’s water analyzed first.

How do Water Purifiers Work?

There are actually several different methods that are utilized by the various different water purifiers that are available, but they all work on the same basic principle – filtering out the contaminants to produce cleaner, purer – and better tasting – water.

The best way to understand just how this is achieved is to look at the different types of water purifier that are most commonly available for homeowners to choose from:

Whole-Home Water Purifiers Whole home water purification systems are the most expensive option available to homeowners. These units are installed directly to the main water line entering a home and primarily remove larger sediment particles and rust. Their downside is that although they do a relatively good job they are not always able to remove the more microscopic water contaminants and some homeowners still find that for drinking water they need a separate in home water purifier as well.

Undersink Purifiers: There are a number of different water purifiers available and which a homeowner chooses may depend upon the specific contamination problem they have. Some remove odors and bad taste only. Others use several different filter cartridges to remove lead, bacteria and small sediment particles as well.

Many people opt for undersink water purifiers because they are really not interested in pure bath water, or pure water to run the washing machine with (although some people are) just in getting clean, pleasant tasting water from the taps in their kitchen and bathroom.

Tap-Mount Water Purifiers: These less expensive devices fit directly to a tap and do not require any plumbing connections or additional hook ups. The most basic models simply filter the water to make it taste and smell better while others do a better job of removing other contaminants.

Countertop or Pitcher Water Purifiers: These are the least expensive and simplest devices available. They are basically simple countertop appliances. They range in size from simple gallon pitchers to larger models that look like a regular bottled water dispenser, complete with spigot. They are limited of course in that they can only process a few liters at a time but if you want to ‘try out’ the idea of water purifiers before making a bigger investment they are a great idea.
