Frequently Asked Questions
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is disinfected for human consumption (such as drinking water), but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications.
Purifying water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, and fungi, as well as reducing the amount of a range of dissolved and particulate material derived from the surfaces that come from runoff due to rain.
The standards for drinking water quality are typically set by governments or by international standards. These standards usually include minimum and maximum concentrations of contaminants, depending on the intended purpose of water use. To find the water quality of your area, feel free to visit the EPA Consumer Confidence Report website for a searchable map.
The EPA allows certain levels of chlorine, ammonia, chloramines, lead, mercury, fluoride, and even arsenic (!) to remain in any city's drinking water. The water you drink, cook with, shower in and bathe in then runs through miles and miles of metal pipeline coated in years of contaminants before finding its way directly to your glass, measuring cup, pet's water bowl or bathtub. Do you really want to take the chance of prolonged exposure?
Chromium-6, popularized in the movie, Erin Brockovich, is a well-known cancer-causing chemical found in a vast majority of the country's tap water. (To find your county's chromium-6 rating, click on the chromium-6 interactive map). Although the chemical can be found naturally, industrial pollution is a major contributor. Even the slightest exposure to Chromium-6 can cause skin burns, pneumonia, pregnancy complications, and stomach cancer. A reverse osmosis system filters down to the micron level, effectively removing the chemical.
Like a car or an air conditioner, water filtration systems work best when the filters are changed regularly. When any filter isn't changed it begins to stop filtering correctly, and you wind up with contaminants making it through the barrier. You ever change an air filter? Yuck! Most of Dupure's systems need a new filter every 6-12 months. If you are unsure when your filter was changed last, please call 877-534-5837 and we can look that information up for you.
