The WaterChef WCG-18 refrigerator filter has a certified capacity of 300 gallons or up to 6 months under typical usage and water conditions.
Every filter has a limited amount of capacity for contaminant reduction. Even though water is still flowing through it and may still taste fresh, there comes a point when it is no longer providing the performance it had when new. Therefore, it is important to change the filter on time to get the best performance from it. There is nothing wrong with changing it ahead of time if you notice a return of off taste or odor similar to the tap water. A sudden or temporary change may be normal with seasonal factors or activities of the municipal water provider.
In an industry riddled with unvalidated and misleading performance claims, having a trusted, independent “third party” organization like WQA, NSF and IAPMO evaluate a water filtration system against an "official" standard or protocol that has been developed by industry experts, public health officials and consumer representatives, gives you the ability to make a sound and informed choice about the performance claims of the system.
Some water filter manufacturers base their performance claims on internal test results from their own laboratories, but you would have to know them very well to trust whether the performance claims they make for their products are true or misleading. Having a trusted testing organization “validate” performance claims gives you the peace of mind you are looking for when it comes to selecting the right system for you and your family.
NO. Beneficial minerals (such as calcium and magnesium) pass freely through the filter, leaving you with water that is both great tasting and naturally balanced.
NO. TDS is a poor measure of water quality. TDS in drinking water is usually attributed to the amount of calcium, potassium, and magnesium that is present in your water supply. These are beneficial minerals that are known to support good health. WaterChef systems have been specifically designed to reduce unwanted contaminants while leaving these beneficial minerals in.
