How to Choose The Best Whole House Water Filter

Unwanted chemicals, minerals, sediments, lead and even rust can be found in many municipal water supplies by the time it reaches your home. Depending on your local supply, you may have safe, drinkable water but it has a bad taste. Perhaps it causes dry or irritated skin after you bathe. In some places, the water in your house is completely undrinkable, not suitable for bathing and not even clean enough to wash your clothes in.

Contaminated water can also lead to limescale crust in the water pipes throughout your house. Not only is this unhealthy but, just 1 mm of this build up can increase your monthly energy consumption by 10%.

So, what are some things that you should consider before buying the best whole house water filtration system for your needs?

  • Find out what is in the water that flows through your house – in order to know what type of filter you need, you’ll need to know what chemicals and minerals are in your municipal water that comes out of your taps. Your water utility company should have an annual report for your area. There are also home tests that you conduct yourself.
  • Choose whether you want a POE or POU filter – POE (Point Of Entry) filters are installed at the main water line, POU (Point Of Use) filters are installed closer to where the water will be used like the kitchen or bathroom sink. A POU filter can be helpful if you want to filter water coming out of a specific source (like the kitchen sink), but if you want to filter all of the water running through your whole home then a POE filter is what you need.
  • Make sure that any whole home water filter you choose is NSF or FDA certified. This will ensure it will actually do its job. A cheap, non certified filter will not stand up to the test.

Once you have these things determined, then you can narrow the filter type, brands and models to consider.
