Water Filtration

A standard canister system is the most versatile choice for RV water filtration.  There is some different terminology used with water filters I will explain that may help you in making your decision.  Microns are sediment filters rated by the size, in microns (one one-thousandth of a millimeter), of units they remove.  Microns are either related “nominal” for approximate and “absolute” for exact.  NSF Class refers to the National Sanitation Foundation’s rating system on the ability of water filters to eliminate chlorine from drinking water.  Class I filters are the best quality; as the Class numbers get larger, the ability of the filter to remove chlorine becomes less.  When a water filter cartridge’s life is referred to, it means the number of months of service the consumer should receive under standard conditions.  Flow rate is the gallons per minute a filter will allow.

Selecting an RV water filter for your water purification system will depend on your lifestyle, budget, and volume of drinking water.  A one-canister system catches sediment and removes some taste and odor problems as well.  A dual-canister system performs a higher level of taste and odor removal while also reducing chemicals, pesticides, lead, heavy metals, and possibly bacteria.  In a three-canister system, different filters will perform different functions.  Some filters focus on taste and odor removal while others perform elimination of mineral buildup.  Another possible factor for consideration when choosing your RV water filter is the locations you are planning to visit. Water in diverse geographical areas contains different impurities and may require different filtration to make the water safe to drink.
