How Whole House Water Systems Work
Whole house filtration treats all water in the household by filtering it from the main water line, which is considered the “point of entry.” Not all water filtration systems are created equal, especially when it comes to a whole house water system versus an undersink water filter. While they both have their benefits, for those that have city water, there is a clear winner.
How Undersink Water Filters Work
Undersink water filters treat water for the faucet they are hooked up to, which is considered the “point of consumption.”
Which is Best for City Water?
When it comes to city water, a whole house water system always trumps an undersink water filter. Municipalities often use chlorine, chloramine, or both to eliminate bacteria from the city’s water supply. While it’s true an undersink water filter can remove these chemicals from a specific faucet, they can still be found in your bathing water, leaving you exposed through skin absorption and vapor inhalation. And, according to the American Journal of Public Health, “up to 2/3 of the harmful effects of chlorine is due to inhalation and skin absorption while showering.”
In addition to being linked to certain types of cancer, skin and inhalation exposure to chloramine from bathing water can also cause:
- Eye, throat, sinus and skin irritation
- Lung aggravation and other respiratory issues
- Free radical exposure
- Digestive problems
- Dry skin and hair
Other City Water Contaminants
And, sadly, chlorine and chloramine aren’t the only unsafe elements that may be lurking in your city water. While municipalities treat and disinfect water for city residents, it is often left with other chemicals and metals, including:
- Water-soluble lead
Exposure to water-soluble lead while bathing or showering isn’t all that troublesome because it can’t be absorbed through the skin. And, iron is more of cosmetic issue as it can cause rust. Nickel and mercury, however, can be absorbed through the skin when bathing in water contaminated with them.
Nickel exposure can cause allergic reactions for those who are sensitive to it. And, according to the Agency for Toxic Substances and Disease Registry, 10-20% of the population is sensitive to this element.
- Kidney problems
- Skin rashes and dermatitis
- Mood swings and mental issues
- Muscle weakness
At the end of the day, filtering just your sink from city water isn’t enough. A whole house water system is truly the way to go.
