Comparing Two Types of Water Filtration
Most homes have some water quality issue, whether on a private well or municipal water system. Virtually every home can benefit from water filtration. It’s the best way to improve your drinking and household water’s taste, quality, and health. However, there are various filters available on the market, which can make it confusing trying to determine which one your home needs. It boils down to two types of water filtration systems, reverse osmosis and whole house.
What is Reverse Osmosis?
Reverse osmosis is a convenient and efficient method for filtering and purifying tap water for drinking and cooking. The compact under-sink unit works automatically in the background to deliver clean, clear, and pure tap water that will rival any bottled water. It’s an excellent option for homeowners that want to improve the quality and taste of municipal or well water. An RO unit typically contains a storage tank, a one to three-stage filtration system, and a faucet for water dispensing. Reverse osmosis uses a semi-permeable membrane to remove metals, minerals, viruses, bacteria, and other pollutants in the water. It also eliminates arsenic, chlorine, copper, lead, and fluoride that many other types of filters are unable to remove from tap water. The micron spores in the membrane filter are so tiny at 0.0001 microns that virtually nothing other than pure water molecules can pass through, making it effective at trapping up to 99% of contaminants in the water. Many RO Systems also utilizes an activated carbon filter to catch any impurities that made it through the membrane before the water flows to the faucet. It also removes any bad tastes and odors. RO systems are low maintenance and only require a filter cartridge replacement, typically once a year.
What is Whole House Water Filtration?
A whole-house system connects to the main hot- and cold-water lines filtering every drop of water at the point-of-entry. Depending on the configuration, the multi-stage filtration system can remove up to 98% of contaminants, including legionella and norovirus, providing clean and healthy water to every faucet throughout the whole house. It’s an excellent option for homeowners on a private well or municipal water system with hard water or other water quality issues. A whole house water filtration system uses an ion exchange system to reduce hardness. As the water enters the home, it flows through a resin media tank that replaces the hard calcium and magnesium ions with soft sodium and potassium ions. The amount of sodium added to soften the water depends on the degree of hardness, but it is about the same amount of sodium naturally present in water. A whole-house system can be customized with additional media to solve other water quality problems like low pH and high turbidity, for example. Whole house filter cartridges require periodic replacement depending on water use. A whole-house system may also be combined with Reverse Osmosis filtration for a complete whole house water filtration
and purification system.
