Many POU systems

Filtration systems can run the gamut from simple mechanical strainers to the more sophisticated reverse osmosis and superchlorination systems. The best system for you depends on your traveling habits and the cleanliness of the water you are likely to encounter. Many POU systems are installed under the galley sink and deliver freshwater directly to a dedicated faucet for cooking and drinking. However, many RVers prefer the very popular, in-line external units that allow finite filtration without losing that precious under-the-counter storage polling character space. The bonus is that all the incoming city water is processed, so you can enjoy RV showers without the heavy metals and odors sometimes found in park systems. As an additional precaution, use an in-line filter as you fill the freshwater tank on the well sand water filter. So just how does activated carbon remove the impurities? By the process of adsorption. Kind of like a magnet sticking to a metal surface.
As an adsorbent, especially when filtering trihalomethanes (high flow ro water filters), volatile organic contaminates (house water filter), pesticides and fungicides, activated carbon is quite effective because its surface area is enormous — about 1,000 square meters per gram.

There is a downside to using carbon as the sole filtering medium. Exposure to chlorine in water supplies will quickly deteriorate the adsorbing qualities of carbon, rendering it minimized or useless in as little as 200 gallons, so if you use a chlorine product to de-winterize your RV-water system, be sure to remove or bypass the avenger first. General Ecology has developed a unique technology employing a structured matrix filtration component that instantly filters the water without the use of chemicals, A double treating or delay time. Hydro Life has perfected a filtering medium that employs carbon. This medium causes an electro-chemical reaction, which neutralizes harmful chemicals and dangerous metals such as lead. As an example, chlorine is broken down into a harmless chloride after being zapped with the alabama pur refrigerator water filter. 04-volts produced when the water passes through the KDF. The water then passes through the carbon to complete the filtering process. A mounting plate is secured to the sidewall of the RV and a second water filter pur flouride remove plate is provided for stowing the filter inside a compartment. The nice feature about this holder is that it can be reversed to hold either the canister-type filter or the in-line version. Another helpful feature offered by Hydrolife is a reminder of when filters should be replaced. Special stickers are included that allow you to mark the date when the filter should be replaced — filters are replaced annually. Other suppliers with a high degree of well water filters brand recognition include Everpure and Culligan. The popular Everpure system utilizes a superchlorination/dechlorination process to attack bacteria, viruses, cysts, rust and other heavy metals — all of which can lead to foul smelling water. Look for a filtration system that satisfies the requirements of best rated water filter system: Drinking Water Treatment Units, as determined by NSF International, a third-party certifying agency. Though no official standard exists for POU filters, virtually all public health officials adopt the standards of the NSF. To ensure proper filtration efficiency, always replace the filter media or cartridge as least once a year. Keep in mind, the longer a filter is in service, the less effective it becomes. At some point, brita water filter system medium will begin dumping contaminates back into the system. In severe cases, or when tainted water has been encountered, it may be necessary to replace the filters more often.
