How Do Water Filtration Systems Work?

Most drinking water systems filter the water into 1 to 6 distinct stages, and within these stages, the water is filtered using reverse osmosis or other techniques to produces water that is cleaner than what was started with. Each manufacturers filtering technique differs slightly, but they are very similar.

Top of the line water filtration systems will take away 50 pollutants or more, whilst some will only do away with a small handful of harmful pollutants. The level of filtration needed depends on local water quality and your personal preferences.

Additionally, most water systems install under the sink in a few short minutes and do now not require an expert, just follow the simple instructions yourself. However, your new water filtration system may be bulky and oddly shaped, thus soaking up big areas beneath your sink.

What to Look for in a Good Water Filtration System

Water filtration systems will always have a filter, and some can affect the pressure of the water. Look for systems that have a pressure range of 55 to 65 psi for this is the typical range for the water pressure in your home. If you have a system with water pressure that is too strong, it can damage your pipes and cause leaks.

We recommend a water filtration system that provides at least three separate stages to reduce pollutants from the water. Remember each stage will remove a different type of contaminants such as chemicals, residue, and sediments.

The best water filtration systems will reduce 10 or more contaminants, and have been NSF certified so that you know its filtration claims are accurate.

Don’t forget that some filters after some point will need to be changed. Six months is the average time before a filter change must take place, while some last up to 12 months. Filters should be easy to change so look for designs that simply twisting on and off.
