5 Different Type of Water Filters

5 Different Type of Water Filters

There are so many different types of water filters available these days, and it can be hard to understand which one is the best fit for your home. What is the difference between Point of Use (POU) and Point of Entry (POE)? Is one type of water filter significantly better than the others? In this article, we will try to clear up some of the confusion with a brief overview of the most popular domestic water filters in use today.

1. Tap Filters

These are often referred to as faucet mounted filtration systems and they attach directly to your faucet. They are easy to install POU systems, and they are relatively inexpensive to buy. They use activated charcoal to reduce the levels of chlorine, improve the water taste and remove unpleasant odors. Their size and speed of use limit their usefulness and efficiency. A tap filter is useless at eliminating microorganisms, and they can typically process around 100 gallons of water before they need to be replaced.

2. Carafe Water Filters

These are filters attached to water jugs that are stored in the refrigerator. They are a cheap way to improve drinking water, but they need to be, and a single carafe would only be able to serve 1-2 people. Cooking using this filtered water is impractical as the pitcher cannot hold enough water to fill a pan. Frequent filter changes are required, and they cannot remove contaminants, such as microorganisms, fluoride or heavy metals.

3. Countertop Filters

These are water filtration systems that connect to an incoming cold water line. They provide adequate levels of cleaner safer water for cooking and drinking. As the name suggests they usually sit next to or under the kitchen sink, and they are a step up from tap and carafe filters. They can remove chlorine and reduce the levels of lead, mercury and some other contaminants. Because of their location, they are of no use in the rest of the home for bathing and other tasks.

4. Reverse Osmosis (RO)

An RO system filters water using high pressures to force the water through semi permeable membrane. They provide extremely clean drinking water because even tiny amounts of contaminants and dissolved solids cannot pass through the membrane. Because of their method of operation RO filters can generate higher than average level of wastewater.

5. POE Filtration Systems

This system will filter all of the water coming into the home prior to its entry into the plumbing system, hence the name. This provides clean and fresh water to every faucet in your home, reducing the level of contaminants, such as chlorine, chemicals, sediment and waterborne microorganisms. This system is the most expensive option of those listed here, but many people enjoy using a higher quality of water for drinking, cooking, cleaning, and bathing. The price of the filtration media is very reasonable, and the maintenance is quite simple.
