The Mist under-sink filtration system is an effective, affordable and DIY way to filter the water that comes from your tap. The average American household uses 27 gallons of tap water a day (according to watercalculator.org). Filtering 27 gallons of water daily can be costly if the incorrect mechanism is utilized. The Mist under-sink filtration system will effectively filter up to 20,000 gallons of water, providing about two years of clean tap water at less than 10 cents a day, making our under-sink filtration system the most cost-effective way to filter water. Installation is quick and easy; once the initial installation is completed, the filter can be replaced with a new one when necessary. Because the filter has such a long life, there is no need to discard the plastic cartridge often, thereby eliminating as much waste as possible from the environment.
