There are different contaminants found in water supply systems in residential buildings. The exact pollutants will depend on the primary source of the water in the plumbing network. However, you will find common and potentially hazardous elements such as bacteria and pesticide residue in both metropolitan and well water supply. You can purchase bottled water for your drinking requirements to avoid ingesting the pollutants in the supply.
However, this is an expensive and, at best, temporary solution. You can resolve this issue by purchasing an undersink filtration product for your home. As implied, the filter is installed under your chosen sink and incorporated into the plumbing system. This will clean the water flowing through the tap, allowing you to obtain safe drinking water. Here are the different filtration systems to consider choosing when purchasing an undersink water filter.
Reverse Osmosis Filter
Reverse osmosis filtration systems are highly effective, so they are popular in undersink products. This technology uses a semi-permeable membrane, a fine filter which allows only selected elements to cross the surface. It can remove most contaminants from your water supply, making your regular water perfect for drinking. Common contaminants that will be removed if choose this system include metals, minerals, asbestos and general organic chemicals. It is prudent to purchase an undersink filter with a pre-filter component. This will remove larger particles such as sediments, minimising the risk of premature failure of the water filter assembly.
The reverse osmosis filter is perfect for removing most of the obvious contaminants and improving water safety. Unfortunately, if your primary concern in your potable water is odours, consider selecting an undersink filter with a carbon filter. This system uses activated carbon to eliminate the pollutants through chemical absorption of the elements. If your water has a chlorine smell, activated carbon will eliminate it, unlike the reverse osmosis alternative. This is also an ideal choice for dealing with herbicides, pesticides and even radon in your home water supply. Unfortunately, carbon filters are limited when it comes to removing metals such as lead. You can achieve best results by combining the reverse osmosis and carbon filter.
Ultraviolet products are not per se filtration devices, but they are designed to improve the drinking water quality. As implied, a UV purifier utilises ultraviolet radiation to eliminate contaminants. It is ideal for incorporation into your undersink system if you are concerned about viruses, fungi and bacteria in your supply. It is prudent to choose systems that also have reverse osmosis or carbon filters.
