How do Whole-House Water Filters Work?

One of the best ways to provide a comprehensive solution for clean water for your family is to install a whole-house water filter. Before you determine whether to purchase a whole house water filter, you need to know a little bit about how the basic filter works. You’ll need to figure out what type and size of the filter meets your family’s needs.

A whole-house water filter system provides clean water for the whole house instead of just the kitchen faucets where drinking water is drawn. The water purifier system becomes the point of entry for the water. These systems work to prevent contaminated water from being used in the home for drinking, cooking, washing clothes and dishes, and bathing.

A whole-house water filter and purification system tends to use a four-step process.

1. Pre-filtering is the first step of most whole-house water filters. Through this step, water entering the home is put through a pre-filter to remove larger particulates, impurities, and contaminants in your tap water. This step traps anything that is about five microns in size. This step is important to the rest of the process of whole-house water filters because it prevents clogging later in the process.
2. Chlorine removal is the next step in whole-house water filters. The filtered water from the first stage is then put through a process to remove any chlorine and other contaminants comparable to chlorine. This step is important in the process of making the water look and taste better. While chorine serves a valuable function at the public water processing level to neutralize biological water contamination, the smell and taste can make your drinking water unpleasant when you draw it from the tap.
3. Activated charcoal is a method of whole-house water filtering that can eliminate the rest of the impurities that were missed through the first two steps. This process will also improve the taste quality of the water. The EPA recommends an activated-charcoal water filtration system for your whole house to give you that extra edge of protection from a wide variety of contaminants that might come in your water. Since the EPA is the agency responsible for the safety of the public water supply for this country, that recommendation means something.
4. Waste removal is the last step in a whole-house water filter system, where the remaining contaminants that have been removed from the incoming water in the previous three steps are flushed away. If a whole-house filter system uses a reverse osmosis system, it will produce the most waste. Using systems that rely on UV light and activated charcoal will produce less waste into the water.

    It is clear that a whole-house water filter that utilizes the activated charcoal methodology is preferable to other water purification methods.
