Household Filters for Cleaner Drinking Water
Written by: Quintin Bentley Crevling
Water is the single most important resource for all life on earth. The human body consists of 60% water, and is designed to expel roughly 2.5 liters of water each day. For this reason, humans need to drink 2-3 liters of fresh water each day to avoid dehydration which can lead to headaches, fainting, and other psychological maladies. To remedy these potentially fatal conditions our society has installed clean running water in all homes. For some communities this water is not as clean as advertised, or may have a strong taste of chemicals used in the water treatment process. Many homeowners opt to install water filtration systems to avoid these potential hazards. There are two types of water filters: point of use and point of entry (also known as whole house). The most common filters are whole house filtration, under sink filtration, and countertop filtration systems.

Whole house water filtrations systems are installed at the point the water enters the home. These filters typically have a four stage filtration system that is designed to remove debris larger than five microns in size, remove chlorine, charcoal filter to improve taste, and lastly the water may undergo some form of reverse osmosis, or another stage of contaminant removal. Since these filters are attached at the point of entry they will provide filtered water for all of your needs including showers, and watering plants. These points of entry systems can filter as much as one million liters of water before they need to be replaced. These systems vary greatly in quality and price ($50-1,500) so be sure to do your homework before purchasing.
Under the sink water filtration systems are a common alternative to whole house filters. Many people don’t care if they shower or water their plants with water that has some contaminants, but most people want clean water to drink and cook with. Under the sink filters use a reverse osmosis system which removes more contaminants than any other type of filters. This form of filtration is so effective that it is how major water bottle companies treat their water. These filters are typically $200-300 dollars and will last about six months. If you are someone who constantly buys water bottles, this could save you hundreds of dollars by providing the same quality of water straight from your faucet.
A less expensive alternative to an under the sink filter is the countertop filtration system. A countertop system rests on the sink’s ledge and has a hose with a diversion valve that connects to the aerator on the faucet. You will be able to choose when your water will be filtered with a diversion valve. All you have to do is turn the valve and water will be diverted to the filter and will pour out of a faucet that’s attached to the filter.
