Some of Our Best Units


The Millennium Drinking Water System reduces contaminants and turns tap water into clean, refreshing water for better health—all for only pennies per day. A four-stage system filters water to the molecular level, resulting in healthier, safer and better-tasting water.

The Millennium system provides an array of benefits, including:

  • Delicious, clean and clear water on demand
  • Removes up to 99% of contaminants
  • NSF Certified for reduction of many contaminants, including cysts, lead and radium
  • Equipped with an attractive faucet
  • Compact design can be installed in multiple locations
  • Environmentally sound water treatment
  • Cost-effective and convenient, making fresh, clean water ready at your tap to end your dependency on bottled water


Drinking water, including bottled water, can be expected to contain a small amount of contaminants. Whether you receive your water through a municipal water source or through a private well, contaminants inevitably exist in your water.

However, the presence of contaminants does not necessarily indicate that your water poses a health risk. The EPA (Environmental Production Agency) regulates disinfection byproducts and aims to limit homeowners’ exposure to them. However, the EPA estimates that more than 260 million individuals are exposed to disinfection byproducts, which can cause cancer or other reproductive and developmental health risks.

The Always Fresh System is tested, certified & approved to protect your family’s drinking water from:

  • Methyl Tertiary Butyl Ether (MTBE). A gasoline additive found in ground water.
  • Volatile Organic Chemicals (VOCs). These include gasoline, solvents, industrial and household cleaners, pesticides and other chemicals that can leach into your water supply.
  • Trihalomethanes (THMs). Chlorine and/or chloramine disinfection byproducts.
  • A heavy metal causing anemia (damage to the gastrointestinal tract and nervous system).
  • Parasite Cysts. Giardia and Cryptosporidium found in 97% of all surface water.
  • Bacteria and Bio Film. Shortens cartridge life due to a buildup of a bio film on the surface of the filtration system.


Changing the 5-gallon bottles each day gets old. With the bottle-less “Point of Use” Drinking Water System, you can enjoy a continuous supply of pure, fresh water—without the hassle.

Whether you want to cool off with a refreshing drink or unwind with a warm beverage, this system fulfills your every need.

With this purification system, you will discover:

  • Premium-filtered drinking water
  • Purification technology that effectively removes pollutants, chlorine and odor-causing chemicals
  • Different systems and features to choose from, including advanced multi-stage filtration, micro-filtration, in-tank UV disinfection and reverse osmosis filtration

  • A treatment that does not alter water chemistry, taste, odor or color
  • Low operational costs—equivalent to energy used in a 40-watt light bulb
