Yes, we generally need a water test to determine what contaminants are in your water and what you want removed.
A whole house system not only provides better tasting, quality water, but can extend the life of your plumbing and water appliances like the hot water heater, dishwasher and washing machine. The KDF not only removes chlorine and heavy metals, it also removes hardness and scale.
Our standard systems will only remove part of the fluoride (about 20%). We make a dual housing system, CT-2KF or UC-2KF, with a special media in the first cartridge to specifically remove the fluoride at a rate of 90-100%.
They mostly use 2 medias; KDF copper-zinc alloy and high quality coconut shell carbon. Depending on your current unique water quality report, this may vary slightly. For instance, if your water source contains contaminants such as radiation you would choose an option for RN-1 Radiation Water Filter that has 4 stages of radiation selective resins.
The copper-zinc removes heavy metals, chlorine, reduces water hardness and creates a bacteriostatic environment. The coconut shell carbon removes organic contaminants like VOCs and polishes the water for great tasting drinking water.
Our drinking water systems last 8,000-50.000 gallons (depending on the model) before needing to be replaced. That means our systems can last from 1-6 years depending on model, number of people, water usage and water quality.
You might notice a change in the taste or smell of the water. Chlorine is usually the first contaminant to be noticed. You can use a chlorine DPD #1 test to measure free chlorine. Also, each system has an estimated amount of gallons of water it will filter before the media bed exhausts. You can calculate that by how much you consume each day from your counter top unit. For a Whole House Unit, contact your local water supplier and ask for the average yearly or monthly usage details. Sometimes this is located on your bill. Note: Some filters need to be replaced by a certain time period i.e. Sediment filters should be replaced no longer than every 6 months.
A CuZn Water system can last from 8-20 times as long as a carbon only unit and removes heavy metals which a carbon unit can not do. The CuZn systems are a perfect blend of high quality, long life and good value.
A CuZn system is less expensive to buy and maintain, leaves valuable trace minerals in the water, and doesn’t waste water like an RO system.
