The biggest challenge is an antique porcelain sink in which you have to drill a hole to install the long neck faucet. If you have a porcelain sink, please contact us and we will issue you special instruction.
The main unit is about 15 inches wide, 17 inches high and 7 inches deep. The 3.2 gallon capacity pure water reservoir tank is about 12 inches in diameter and stands about 14 inches high.
If you just don't have the space under the sink, are renting for a short time or traveling, our counter-top units are the answer. Model 463 (2.2 gallon reservoir), 445 (1.25 gallon) or 465 (1.0 gallon). Top
Reverse Osmosis is a process in which dirty water is forced through a special cellophane-like RO membrane under elevated pressure. The cold water inlet side must have a static pressure in the range of 40 to 100 psi for our Conqueror series and the tabletop models 460 and 465. The Gladiator series units are used when the inlet water has no, or not enough, pressure. They have a built-in booster pump which pressurizes water to the proper level.
The hole size in an RO membrane is no larger than 0.0001 microns. Water (H2O) happens to be nature's smallest liquid molecule at room temperature and it slowly seeps through the tiny holes in the membrane, while the contaminants consist of much larger molecules and are stopped. Oxygen dissolved in the water also passes through the membrane. That's why RO is used for aquarium where fish can live. The dirty water left behind is drained out at a constant rate determined by the capillary flow controller unit.
In constrast to the RO process, the hole sizes of mechanical and ativated charcoal filters are in the range of 1 to 5 microns in diameter. Aside from the electro-chemical adsorption process in the activated charcoal filter medium, lots of impurities and molecules can and will pass through these holes.
All our RO systems are configured with a combination of sediment, activated carbon and RO filters in series. Each is designed to optimize the system performance and component longevity. They are also equipped with an auomatic shut-off valve. It senses when the storage tank is full, and shuts off the RO process. Therefore the water is not wasted. Top
The RO membrane also removes:
Yes, RO removes bacteria and viruses
Viruses are in the range between 0.02 and 0.5 microns. They are still 100 to 2,500 times larger than the holes in the RO membrane and cannot get through.
Yes, bacteria can grow in the RO system
To insure the system is indeed free from bacteria and slime, we recommend that you disinfect an RO unit every year in warm locations and couple of years in milder and northern locations. We have a simple sterilization procedure using Clorox bleach.
We do not mean to imply it happens often, but there have been cases of bacteria in tap water adversely affecting people's health, sometimes even fatally (the 1993 outbreak of cryptosporida in Milwaukee). Lead, asbestos and nitrates, all bad for health, have often been detected. Cases of ground water contamination from ethylene glycol (anti-freeze) used in de-icing airplanes or from chemical plants have been reported.
Water from individual wells does not fare much better. We have tested extensively in New England towns where each house has its own well. It is often too acidic, too hard, contains too much iron, manganese or radon. In each case, water to the house is treated by a point of entry system that relies on inexpensive (read impure) chemicals to combat the condition(s). It is best to remove these added chemical impurities before drinking it.
We have detected in well water arsenic, radioactive radon (of up to 100,000 pico Curie/litre), pesticides, lead, copper, ecoli bacteria, nitrates, odor, color, you name it! The safest bet is to take out these impurities from your drinking and cooking water. And a competently designed RO system is most effective against the widest range of these pollutants. Top
Bottled water is expensive, inconvenient, and you don't quite know its quality. Distillers remove microbes and most minerals and metals, but they may not remove volatile organic chemicals (often toxic) that evaporate at lower than 100°C temperature, because they evaporate first and recondense. Boiling proces drives out oxygen, so fish cannot live in distilled water.
You can purchase numerous inexpensive carbon only filters in various configurations, but they all suffer from too large (relative to RO) filter mesh size of several microns and too short an adsorption cycle (time period in which water is in contact with activated carbon). Things like copper, arsenic, lead, cryptosporidia, giardia and radioactive radon can only be stopped by the RO filter.
Ceramic filters are only mechanical sediment filters with a very uniform hole size of about 0.8 microns in diameter. Since there is no electro-chemical adsorption process involved (as in carbon), chlorine and odor are not removed. The ceramic cartridge is washable.
If you are a person of discernment who wants nothing but the best quality water for you and your family, the answer is the RO purified water. Top
You are made up of about 28 trillion cells, which consist of more than 70% water. These cells constantly cleanse, nourish and regenerate to keep you alive and healthy. You certainly don't want to tax them with the added burden of cleaning out the industrial and natural contaminants found in water today.
Some people say, oh, but the minerals are important as well as making the water taste good. But what about some harmful ingredients that might be lurking in the raw water? Look at the spent cartridge above! It is safer to drink the RO purified water and then supplement minerals.
In this connection, we highly recommend a line of natural, organic, mineral- and vitamin-rich nutritional supplements. Latest medical research appears to show their efficacy in lowering the risk of cancer and heart disease. Call us and we will help you order products and get you going.
In addition to its being pure and safe, the RO water is absolutely delicious! Wait till you taste coffee, tea or the water itself! Top
