01 / THE EXACT CONFIGURATION

Replacement filters

Claims below apply to WD-G3P800 + G3-N1CF + G3P800-N2RO + G3-N3CB as a complete configuration. Physical fit alone does not establish certified performance.

G3-N1CFSediment and carbon prefilter · Sediment and carbon prefilter

550 gallons / 6 months. Replace at the earlier of the documented volume or time limit; follow source instructions for any earlier replacement triggers. Capacity / component source

G3P800-N2RORO membrane · RO membrane

2,200 gallons / 24 months. Replace at the earlier of the documented volume or time limit; follow source instructions for any earlier replacement triggers. Capacity / component source

G3-N3CBCarbon finishing filter · Carbon finishing filter

1,100 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

The certified configuration uses the base CF, RO and CB filters. An alkaline add-on sold in some bundles is not established as part of that certification here. Page-2 microbial and NSF 401 tests are not presented as certified claims. The advertised 800 gpd is production, not a verified instantaneous service flow or household daily-use ceiling.

02 / DOCUMENTED PERFORMANCE

Reduction claims

IAPMO certification stated in the manufacturer document. The registry was not independently checked. Only captured source-supported claims are shown; laboratory performance is not a guarantee for your water.

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.

REPLACEMENT BUDGET

Annual filter cost

$229.96365 gallons / year · all 3 replacement items
  • G3-N1CF · 2 units / year$59.98
  • G3P800-N2RO · 1 units / year$139.99
  • G3-N3CB · 1 units / year$29.99

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.
