|Ask The Expert: ice maker filters
Q small residential 1/4-inch ice maker filters should be changed out every six months, correct? Does that also hold true for pre-filters on an RO system?
Raymond Balderas Casiano
A For this question, we went to Leigh DeGrave at Watertec right here in Tucson, where RO systems are a significant part of the residential water market. He advises that the frequency of filter replacement has many variables. Overall feed water quality plays a role, as does the quantity and quality of the carbon within the filter. These types of filters typically should not be used on water that is not microbiologically safe, or of an unknown quality, without adequate disinfection before the filter, according to DeGrave. That said, he noted that, “filters typically will last no longer than six months or up to 750 gallons, and many consumers will determine that replacement is necessary when taste changes or odor appears.”
