How do I choose between an under sink or countertop water filter? Under counter systems are the most popular choice for people who own their own home because the filter housing can be mounted on the cabinet wall below the sink where it is out of sight. The filter draws water from the cold water supply line below the sink. Filtered water is delivered via a dedicated filtered water faucet positioned on the countertop at the side of the sink. The filtered water can also be diverted to a refrigerator or instant hot dispenser. Countertop filters are great for people who are renting their home and who do not want to drill a hole through the countertop to install a drinking water faucet to connect to a water filter installed under the sink. Countertop systems are portable and easy to move. A faucet diverter valve hooks the filter up to the end of your kitchen tap so that you can get filtered water without interfering with the normal use of your kitchen tap. You must have a standard faucet that is compatible with attaching a faucet diverter valve.
What is NSF Certification? NSF® is an internationally recognized, not-for-profit, third-party testing organization that tests and certifies products to ensure they meet strict public health standards. Certified water filtration products are tested to verify that they meet certain standards for health and aesthetics. Certification by NSF® assures the consumer that:
Claims of contaminant reduction are true.
The system does not add anything harmful to the water.
The system is structurally sound.
Advertising, literature and labeling are not misleading.
Materials and manufacturing processes do not change.
To ensure that manufacturers continue to meet these requirements, NSF® conducts unannounced inspections of manufacturing facilities at least once a year.
Is the stainless steel CB-VOC water filter certified by NSF? Yes. Your CB Tech Drinking Water System (CB-VOC) has been tested and certified by NSF® International under NSF/ANSI Standard No. 53 (Health Effects), NSF/ANSI Standard No. 42(Aesthetics Effects) and NSF/ANSI Standard 401 (Incidental Contaminants/Emerging Compounds). See the Performance Data for details.
What is the CB Tech warranty? The CB Tech CB-VOC drinking water filter (formerly known as Multipure™) includes a Lifetime Warranty on the stainless steel housing (provided that the filter be changed at least once a year) and a 1-Year Warranty on the accessories.
What makes the stainless steel CB-VOC filter system so effective? Nationally recognized standards established for the drinking water treatment industry confirm that the most effective systems for the removal of both aesthetic and harmful contaminants are those that utilize solid carbon block filters. Solid carbon block filters contain millions of microscopic pores which micro-strain every molecule of water passed through the filter. Carbon blocks are dense, compact and stable with millions of enormous interior surfaces which allow water to be in contact with the carbon for a longer period of time, providing greater adsorption of the many different chemicals, pesticides, herbicides and certain heavy metals. Contaminants with a physical size are removed when water passes through the pre-filter, which helps keep the carbon block from clogging prematurely.
Does the CB-VOC drinking water filter remove healthy minerals from my drinking water? CB Tech drinking water systems (formerly known as Multipure™) do not remove healthy, naturally occurring minerals from your drinking water.
How are chemicals and lead taken out while healthy minerals remain in the filtered water? Minerals dissolved in water are in solution and do not have dimension. They pass through the filter unchanged. The materials used in carbon block filters are specifically selected for their ability to react with the chemicals in the water but not with healthy natural minerals. Specialized carbon block can be activated to target specific dissolved impurities such as lead, VOC’s and chemicals. These contaminants are adsorbed and adhere to the interior surfaces of the carbon block rather than remaining in the water which passes through the filter. This occurs because of a chemical reaction called adsorption.
What is the difference between reducing chlorine and THMs in drinking water? Chlorine is easily removed from drinking water. However, chlorine is a highly reactive substance which forms hundreds of chlorination by-products when chlorine comes in contact with organic material. Chlorination by-products have a different molecular structure than chlorine. The largest known group of these chlorination by-products are called THMs (trihalomethanes). Unlike chlorine, THMs are difficult to remove from drinking water. Exposure to THMs is linked to various cancers. They are significantly more toxic than chlorine.
Does the CB-VOC drinking water filter remove Trihalomethanes (THMs)? CB Tech Drinking Water Systems (formerly known as Multipure™) have been tested and certified by NSF to reduce chlorine and trihalomethanes for the entire service life of each cartridge - a benefit that most other drinking water filters cannot honestly claim. Chlorine is relatively easy to remove. However, trihalomethanes (by-products of chlorination, also called THMs) are a different story. Although formed from chlorine, THMs have a completely different molecular structure than chlorine. THMs are extremely difficult to remove, especially on a sustained basis. Many water filter companies lead you to assume that their product will protect you from THMs for the service life of their filter when, in fact, it is only the reduction of chlorine that their cartridges can fulfill for this period of use.
What is the difference between Adsorption and Absorption? Adsorption happens when molecules adhere to the surfaces of a substance with which they come in contact. This is how carbon cleans water. Absorption happens when molecules are taken up by or enter a substance. This is how a sponge soaks up water.
How do I know when to change out my CBTVOC drinking water filter cartridge? Cartridge life will vary in direct proportion to the amount of water used and the type and level of impurities in the water being processed. It is recommended that the cartridge be replaced when the first of the following occurs: a) 750 gallons of use b) 9 – 12 months of use c) the flow rate diminishes (which occurs when the cartridge becomes clogged with particulate matter) or d) the cartridge becomes saturated with bad tastes and odors. DO NOT EXCEED ONE YEAR OF USE. The cartridges cannot be back flushed, or rinsed and used again. Even if your cartridge is still white and the flow rate is still high, once your cartridge has been wetted it should always be replaced within a year, regardless of remaining capacity. watermatters™ offers a free automated email reminder service to help you remember when to change out your cartridges.
Why should hot water never be run through a carbon filter? Running hot water through a carbon block cartridge can cause the carbon to dump adsorbed chemicals and contaminants into the finished water. Hot water (below 212 degrees) should not alter or damage the raw materials of the cartridge itself. If you accidentally run hot water through the filter, immediately turn off the hot water and run cold water through until the filter cools and then flush the filter for about 3 minutes. The filter then will again perform effectively. Don’t drink the hot water.
What should I do with my CB-VOC water filter when I go on vacation? Do not allow water to sit in the drinking water system for extended periods of time (10 or more days) without being used. If the system is to be left unused for more than 10 days, drain all the water from the system and remove the cartridge. The best procedure is to install a new cartridge when you return from your vacation. If you choose to keep the same cartridge, store it on a clean, dry surface in a well ventilated area while you are away. It can be covered loosely with a breathable cotton cloth (cheese cloth). When the cartridge is reinstalled and the system is put back into use, the cartridge will need to be saturated again by letting water run through the system for approximately 15 – 20 minutes. Do not enclose the wet cartridge or place it in a moist environment (refrigerator) as the moisture could cause bacteria to grow on the filter. Never expose your filter to freezing temperatures.
What does ‘inline’ mean? ‘Inline’ describes a water filter that is positioned between the source of water to be filtered and the device that will deliver the filtered water. This device could be a dedicated drinking water faucet, a fridge, an ice maker, an instant hot water dispenser, etc.
How can I connect the filter to a fridge, ice-maker or hot water dispenser? The CB Tech stainless steel drinking water filter (CB-VOC) is very versatile. By purchasing a few extra parts, it can be converted from a counter top filter to an under counter filter (or vice versa) and it can be used as an inline filter to a fridge or instant hot water dispenser. By using a Tee-connector, your drinking water filter can supply filtered water your dedicated filtered water faucet as well as to another water dispensing device.
