FAQ

There are several distinct differences:
  1. A Brita filter is a single carbon filter used to remove Chlorine, Taste and Odor that may be present in tap water. Our multiple stage water filtration system uses several carbon filters, sediment filter and membrane filter. The use of multiple filters enables our system to filter out more of what you don’t want in your drinking water such as dirt, rust and chlorine just to name a few thereby providing you with higher purity drinking water.
  2. The life span of our filter also has a longer useful life of up to 12 months when compared to the 4 month replacement schedule of the Brita filter.
  3. Brita filters utilize single cartridge filtration whereas our system uses reverse osmosis purification, a higher level of water purification.
  4. Fridge filters are similar to Brita filters because they utilize a small carbon filter to remove Chlorine, Taste and Odor that may be present in tap water.
There are several ways to look at this comparison:
  1. From a water process standpoint, if the bottled water you are purchasing is purified by reverse osmosis, then they are processed in the same manner.
  2. From a cost standpoint, when you’re purifying your own tap water, you are saving in the cost per serving when compared to the store purchased bottled water.
It should be noted that bottle water is not all processed the same way. Some bottled water companies simply bottle naturally filtered spring water. Take a moment to read the label and if it says the water is purified by reverse osmosis, then a higher level of water purification was used to filter the water.
As water passes through the atmosphere in the form of rain, snow, sleet, hail, dew, or fog, it picks up impurities and gases. Because water is the universal solvent, it also picks up impurities as it travels through the earth as ground water. Water will dissolve whatever substances or minerals it comes in contact with.
Water hardness is caused by calcium and magnesium in ground and surface water. If high concentrations of these minerals are present in your drinking water, the water is considered hard. These minerals come from sedimentary rock such as limestone that dissolves into water. The result of hard water is difficulty making suds for washing and buildup of minerals on taps and other fixtures. Water containing low concentrations of calcium or magnesium is called soft water.
Water hardness shows up as scale in water heaters or on plumbing fixtures, soap deposits on dishes and fabrics, and soap scum in sinks and bathtubs.
