Replacement filters
Claims below apply to UC300 + UF-35 as a complete configuration. Physical fit alone does not establish certified performance.
600 gallons / 12 months. Replace at the earlier of the documented volume or time limit; follow source instructions for any earlier replacement triggers. Capacity / component source
UF-35 is the complete three-filter kit; do not price it as one of its individual stages. The PDS cyst row contains rounded percentages; consult the original data. No percentage claim is extrapolated here.

Materials & structural scope
NSF/ANSI/CAN 372: Lead-free plumbing materials. This does not establish contaminant removal from water.
Unlisted contaminants have no captured claim here. An absent catalog claim does not prove absence of certification.
Annual filter cost
- UF-35 · 1 units / year$79.99
For each item: round up the larger of annual water use ÷ capacity and 12 ÷ replacement months, then multiply by quantity and unit price. This conservative full-year budget does not credit the filters supplied with a new system. Multi-pack prices are allocated per filter; buying whole packs can cost more. It excludes system purchase, hardware, optional upgrades, shipping, tax, labor, water and electricity. Editable prices are your assumptions.
