However, people are free to do whatever they want, regardless of whether it makes any sense.

Nova recommends changing the filters every 26,000 gallons. I asked how they determined that figure and the answer was basically that they are dirty enough at that point to be icky and inefficient.
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.
