Water Filtration Basics

Point-of-use water conditioning options include carbon filtration, ultrafiltration, ultra violet, and reverse osmosis (RO) options for under counter and countertop and pitcher filters for your home drinking needs.  Recent advances in technology also allow a post-RO stage to adjust mineral content and pH of the conditioned water in under counter systems.

Installing a carbon filter-based water filtration system is a great way to keep your water tasting great. Other advantages to installing a point-of-use water filtration include reduction of sediment and contaminants from your water source, whether a municipal water supply or well. Water4 Systems realizes that each locality’s and household’s water filtration needs vary, so your personal selection of the correct filtration for your needs is the key to you, you family, and your guests enjoying healthful water now and into the future.

Ultra Filtration uses a hollow fiber technology, a membrane filtration process which uses standard home water pressure to push water through its semi permeable membrane.  A .2 micron UF traps suspended particles and materials of high molecular weight, allowing only fresh clean water and dissolved minerals to pass through.

Some households want to add Ultra-Violet Filtration to pre-treat or post-treat the drinking water, both sterilizing and disinfecting the water by irradiating it with UV light. UV light, at wavelengths between 250 and 270 nanometers (UV-C or UVC band), non-chemically kills many species of bacteria, mold spores, viruses and other microorganisms that most people do not realize may be present in your water supply. The UV adapter for water purification systems relies on the movement of water through an enclosed vessel that contains a UV lamp.

Reverse Osmosis (RO) systems remove nearly everything from your drinking and cooking water, except the water. RO systems can be countertop or pitcher units, but many households prefer the RO water filter to be under the sink for a discreet appearance.  Residential RO systems have filter capacities from 18 to 100  gallons of water daily. The reverse osmosis membrane at the heart of the system reduces microscopic contaminants such as Arsenic, Lead, Percolate, Chromium, Copper, and Radium for safer and generally better tasting water for drinking and cooking.

A re-mineralization and pH stage adds to your drinking and cooking water what the RO removes, but that most people unknowingly want in their water.  Most RO filters remove calcium and magnesium from your water that your body actually wants and needs.  People who drink only RO water may find that they need to take a multivitamin or mineral supplement.  Some people also find that having calcium and magnesium in your cooking water improves the taste of your coffee and some other foods and beverages.

In addition, some claim health benefits to increased alkalinity in their drinking water.  A post-RO pH-adjusting stage may meet their desires.

Water4 Systems offers 2-stage, 3-stage, 4-stage, and 5-stage point-of-use filtration systems for your home drinking and cooking needs.
