Our most vital nutrient has an alarming tendency to carry harmful substances. According to the Environmental Protection Agency (EPA), there are around 316 contaminants in U.S. tap water, including different forms of bacteria, viruses, toxic metals, and numerous harmful chemical compounds[^1^]. Utilizing a water filtration system at home is essential to keep ourselves away from potential health issues related to contaminated water. This article offers a complete guide on the best water filtration systems designed for domestic use.
Why Do You Need A Water Filification System?
Before discussing the specific brands and types of home-based water purifiers, let’s first understand the reasons you might need to invest in one. A home water filtration system removes more contaminants compared to a regular tap filter, improving both the smell and taste of the water. Furthermore, water purifiers increase the general health of your family by eliminating various potentially harmful chemicals and metals from the water[^2^].
Home-based Water Filification Systems: A Comparative Study
There are several types of home water purifiers available in today’s market, including reverse osmosis, activated carbon, ultraviolet (UV) purification, and distillation systems. To aid you in making an informed decision, let us draw a comparison.
Reverse Osmosis (RO) Systems
RO systems have earned high popularity on account of their effectiveness. They work by applying pressure to force water through a semi-permeable membrane, thus filtering out contaminants. High-end RO systems can filter out up to 99% of contaminants, including lead, mercury, chlorine, and asbestos. However, they require regular maintenance and often waste quite a lot of water.
Some of the best RO systems in the market include APEC Water Systems ROES-50 and iSpring RCC7 High Capacity Under Sink 5-Stage Reverse Osmosis.
Activated Carbon Filters
Activated carbon filter systems are the most common type of water purifiers. They work by attracting and trapping contaminants as the water flows through. While they are excellent for removing organic compounds, chlorine, and improving the taste and odor of water, they are ineffective against metals, salts, and minerals.
Renowned activated carbon filters on the market include Brita Standard Metro Water Filter Pitcher and the PUR PFM400H Faucet Water Filtration System.
Ultraviolet (UV) Purification Systems
UV purification systems use ultraviolet light to disinfect water, by killing bacteria and viruses. They’re incredibly efficient, user-friendly, and do not need any chemicals or additional heat. However, these systems do not remove other types of contaminants such as heavy metals or chemicals.
Recognized UV purification systems include the HQUA-OWS-6 Ultraviolet Water Purifier and the ULTRAVIOLET Water Purifier Whole House Sterilizer.
Distillation Systems
Distillation water purifiers work by boiling the water and then condensing the steam back into water. This simple process effectively removes bacteria, viruses, heavy metals, and chemicals. However, they require a lot of energy and are relatively slow compared to other systems.
Reputable distillation systems include the Megahome Countertop Water Distiller and the CO-Z Water Distiller.
Factors to Consider When Buying a Water Filtration System
Before purchasing a water purification system for your home, you must consider a few factors such as the initial cost, maintenance cost, efficiency, and types of contaminants present in your water source. It’s worth investing in a water test kit to identify the contaminants in your home’s water, allowing you to choose a system specifically effective against those contaminants.
Conclusion
Always remember that the best water filtration system depends on your specific needs, as each system has its strengths and weaknesses. Irrespective of your choice, having a water filtration system in your home serves as a crucial line of defense against various waterborne diseases, ensuring safe and healthy water for you and your family.
