1 – Reverse Osmosis (RO) Filtration Systems
A whole home RO system entails the use of a semi-permeable membrane that separates and filters out contaminants. RO systems are considered to be among the most effective home water filtration methods because they produce remarkably clean drinking water. RO filtration removes roughly 99% of contaminants from your water supply, including volatile organic compounds (VOCs), some pesticides, solvents, and chlorine.
With a more intensive filtration process, you will likely need to spend more money to install it. Most RO systems will also require a pressurized water tank because filtration occurs at a slower rate. Although RO systems produce the cleanest and safest drinking water, they also create a lot of brine. They are still, however, an excellent option when it comes to ensuring that you and your family have reliable access to a healthy supply of water.
2 – Activated Carbon Filtration
Activated Carbon filtration systems involve a fine carbon powder that effectively removes (the taste and smell of) chlorine as well as other chemical contaminants. Some of those impurities include lead, VOCs, and microscopic cysts in water. The high porosity of the filter also allows it to absorb more contaminants in your water supply. Activated carbon is effective in preventing bacterial growths from taking place in your water supply.
Activated carbon filtration for your entire home is very affordable to install and is compatible with other filtration technologies. Most whole home water purifiers do not achieve the same flow rate and lifespan as activated carbon filters. We should inform you though that activated carbon cannot remove hard minerals and sediment. For this, you will need to install a separate filter.
3 – Distillation
Distillation is the process of producing evaporated water by boiling it via an electric heater. During evaporation, the steam is collected and condensed into distilled water. When you vaporize the water, you are discarding and eliminating most of the contaminants and minerals contained within your water supply. Distillation can be a slow and time-consuming process, which is not ideal for households of four or more people.
Distillation will remove the majority of contaminants from your water supply, making it a viable whole home water filtration system. This includes dissolved solids, excess minerals, and bacteria. However, the low output of distillation makes it unfeasible for larger families. The system will also consume a lot of electricity, which means that it will come with a higher operating cost.
