Our municipalities work very hard to provide safe, disinfected water for their customers. This is quite evident when you consider the difficulties involved in providing safe drinking water through a vast distribution network. If you use water that comes from a municipal water supply and wish to provide your family with added “peace of mind”, then we believe a UV system acts as an inexpensive insurance policy against the possibility of drinking bacteriologically contaminated water.
Yes, Aquasana recommends you have a licensed plumber install the system for you, to ensure that the system is installed properly. Since most licensed plumbers carry insurance to cover any damages caused by an installation error, having a licensed plumber install the system for you will give you the security that the work was done properly and that the installation is backed up by the plumbing company’s insurance plan. Not having the system installed by a licensed plumber will void the warranty of all our whole house filter systems.
Disinfection is recommended for all water supplies that are not protected by a municipal water source. Unfortunately, due to the uncertainties that exist with our current water supplies, we can no longer rely on the fact that our water supplies “may be safe”. By providing your own disinfection, you are taking the responsibility of ensuring the safety of your water supply for you and your family.
City water is pre-treated to make sure it is free of bacteria, viruses and common contamination sources. City water is regulated so that the contaminants regulated by the various Kenyan Regulatory Authorities fall within or below the recommended guidelines. Well water is untreated water from an underground aquifer that is pumped into a house. Well water may contain higher than average levels of iron or sulfur, or other contaminants.
The filtration system is installed at the point where the main water supply enters the home, delivering filtered water to all subsequent outlets.
Hard water contains a higher than average amount of dissolved minerals (primarily calcium and magnesium), and a higher concentration of multivalent cations (Ca2+ and Mg2+). Hard water is mostly a nuisance as these dissolved minerals can clump together to produce scale, which can harm your internal pipes, plumbing, and home appliances.
No, hard water is more of a nuisance than a health issue, and is not considered contaminated. Most water sources in the Kenya are considered hard. Is hard water safe to drink? Yes, hard water is healthy enough to drink.
Yes, hard water is healthy enough to drink.
The most recognizable trait of “soft” water is how much more soap lathers, as opposed to hard water, in which soap lathers less due to the higher concentration of minerals. Water softeners reduce the negative effects of dissolved minerals in water that can clump together and produce scale buildup.
Soft water does not mean clean water. Your water can be soft and still have contaminants present in the water.
Yes, soft water is considered potable as long as the water has not passed through a sodium-based water softener. Drinking water from a sodium-based softener increased your daily intake of sodium, which can lead to health problems in sodium-sensitive individuals.
The top tank contains a KDF-55 medium (A mixture of 55% copper and 45% zinc mineral alloy) for the reduction of chlorine and certain heavy metals, as well as a crushed mineral filter stone to enhance the water’s pH and control scale on internal plumbing. Both media are bacteriostatic, which means they prohibit bacteria and algae from growing or developing within the system.
A salt-based water softener is a system designed to remove/reduce calcium and magnesium from the water by exchanging it with sodium. This is done through an ion exchange resin that alters the molecular structure of the calcium and magnesium from a divalent ion to a univalent ion, making the water “softer.”
Softeners do not remove chemical contamination themselves, but softeners sometimes have a carbon filter working in conjunction with the softener to treat contamination.
The EQ-WELL-UV top tank contains a KDF-85 medium (A mixture of 85% copper and 15% zinc mineral alloy) for the reduction of hydrogen sulfide and heavy metals like iron, as well as a crushed mineral filter stone to enhance the water’s pH and control scale on internal plumbing. Both media are bacteriostatic, which means they prohibit bacteria and algae from growing or developing within the system.
KDF stands for kinetic degradation fluxion, which is a redox filtration medium. KDF uses a unique combination of copper and zinc that creates an electrochemical reaction. During this reaction, electrons are transferred between molecules, creating new, harmless molecules and compounds. Free chlorine, for instance, is changed into benign, water-soluble chloride, which is then carried harmlessly through the water supply. Similarly, some heavy metals* such as copper*, lead*, mercury* and others, cling to the medium’s surface, thus being effectively removed from the water supply.
The bottom tank contains a carbonized coconut shell medium that reduces synthetic chemicals and VOCs.
The EQ-WELL-UV bottom tank contains a carbonized coconut shell & catalytic medium that reduces synthetic chemicals, hydrogen sulfide gasses and VOCs.
Our whole house filters do not remove calcium. To reduce calcium or other hard mineral buildup, we offer whole house filter + salt-free conditioner combo systems.
The EQ-600 is certified by NSF International to reduce >97% of chlorine for 600,000 gallons or 6 years. The EQ-1000 is also tested to reduce chlorine by >97% for 1,000,000 or 10 years.
All Aquasana Whole House Systems perform at 7 gallons per minute (gpm).
As long as your home is less than 3500 sq. ft. and you have 3-1/2 bathrooms or fewer, you should not experience any noticeable drops in pressure. If you have a larger home, we can build a custom system to deal with the typical water capacity of your home.
Chloramine is a disinfection agent comprised of chlorine + ammonia used as an alternative to chlorine in some city water treatment facilities. They use chloramines for two big reasons: (1) chloramine is less reactive, so it does not create as many disinfection by-products as chlorine, and (2) chloramine is more persistent, and remains in the treated water through the distribution network all the way to the taps in the homes the treatment facility serves. For customers with chloramine in their water, we offer the EQ-400. The EQ-400 features upgraded catalytic activated carbon media , which has a higher surface point and is able to handle the aggressiveness of the chloramine for a longer period of time than the standard coconut shell carbon used in the standard whole house systems.
Our EQ-WELL-UV Well Water Whole House Filter comes standard with the Aquasana Sterilight UV Filter specifically designed to kill bacteria and viruses. For our city water whole house systems (EQ-600 and EQ-1000) that do not come standard with the UV filter, we offer the Sterilight UV Filter as an add-on item that easily attaches to any of our whole house filter systems.
Yes, as a result of recent findings by academic researchers, it has now been proven that UV is the best available technology to treat these protozoan cysts. In addition, the dose levels required to inactivate these cysts are actually quite low: less than 10 mJ/cm2 for 99.9% reduction of both Cryptosporidium parvum and Giardia lamblia.
Yes, E. coli requires a UV dose of between 6 to 10 mJ/cm2 to achieve a 4-log (99.99%) disinfection. This is well within the capabilities of our UV systems which actually deliver a minimum of 30 mJ/cm2.
UV disinfection typically offers a 4-log reduction (99.99%) for both bacteria and most viruses. UV is more effective than chemical disinfection processes at destroying a wide range of viruses.
