How to Choose a Type of Home Water Filter
The quality of the water that comes out of your tap varies based on where you live and your plumbing. It is always a good idea to filter the water you drink and there are many different options for water filtration systems. Read this article to learn more about the available systems and decide which type of home water filter is right for you.
Activated Charcoal: A Popular Type of Home Water Filter
Activated charcoal filters come in the form of water filtration pitchers, faucet attachments, and built-in refrigerator filters. The charcoal attracts and absorbs toxins like chlorine, volatile organic compounds that come from pesticides and detergents, and sediment.
They don’t remove heavy metals and dissolved inorganic substances. If your water tests positive for substances like lead or mercury, an activated charcoal filter will not be sufficient.
Reverse osmosis removes 99% of all contaminants in water, including heavy metals and salts. Most reverse osmosis systems have a built-in carbon filter to remove chlorine. While this is a great type of home water filter for areas with lead and other heavy metals, the process wastes about 4 gallons of water for every 1 gallon purified.
A water distillation system brings water to a boiling point so that it evaporates, leaving behind pollutants that have a higher boiling point. This process separates water from contaminants and then condenses the pure water vapor into liquid in a separate container.
This type of home water filter removes most impurities except for certain pesticides and volatile organic compounds that have a lower boiling point than water. Like reverse osmosis systems, some water distillers have a carbon filter attached to remove the remaining pollutants.
UV Light Filter
If your home drinking water tests positive for bacteria or viruses or if that is a concern in your area, a UV light filter may be your best choice. UV light treats bacteria and viruses in water by making microorganisms unable to replicate. It does not remove other kinds of pollutants, so if you want to remove chlorine, VOCs, heavy metals, and other impurities, use it in conjunction with another type of home water filter.
