The filters may last as long as you want them to, but they definitely become less effective after their suggested filtering limit. It is recommended
to change the filters once the limit has been hit. However, if your filters for that little thing are over $100, I would suggest getting a better
water filter, something like reverse osmosis, as I got one not long ago, and the replacement filters are only $27.00 every 6 months, or 1000 gallons.
This is the system I have for under the counter,
