I am using a KX Matrikx +CR1 19-250-125-20 Carbon Filter (19-250-125-20)
for my home. The specification for this filter for Chlorine Taste & Odor Reduction Capacity @ Flow is >20,000 gal. @ 5.0 GPM. I use ~6,500 gallons per month. You site recommends changing every 6 months to 1 year. Based on my usage, how often should I replace this filter?
Does this / how does this correspond to the >20,000 gallon spec?
