Based on the specs of the carbon block filters I use and the chlorine levels in The Villages potable water, the carbon block filters, that I use, are good for approximately 40,000 gallons. This is essentially 2 years, rounding up a bit, for the amount of water we use. The 5 micron pleated sediment filter, in front of the carbon block filter, can be hosed off and is typically pretty clean at 2 years. I suspect the amount of sediment in the potable water in The Villages varies somewhat; our water is very clean now but it was pretty dirty for the first 2 years we were in the house (new construction area). I do occasionally measure the chlorine level to check and this interval has been fine. YMMV.

If someone has a better MEASURABLE metric, please share. Saying 2 years or 5 years is meaningless since every household has different usage needs. A home of 4 people that lives in TV year around is vastly different than a single person that snowbirds.
