Compare the first 36 months
Adjust checkout prices, replacement intervals and installation quotes. The estimate uses included initial filters and counts replacements due before month 36. It excludes tax, shipping, water, electricity and repairs. The APEC complete kit includes prefilters, so a coincident prefilter purchase is counted once.

Filters can reach their rated volume before the calendar interval. Shorten the interval if your water use warrants it. Waterdrop’s N2RO cartridge page lists both 2,200 and 2,900 gallons. The 24-month default is a calendar estimate. Confirm the volume limit for the exact cartridge. If you reach it sooner, use a shorter interval. For APEC, the starting point is 12 months for prefilters and 24 for the complete kit within the published ranges.
