01 / THE EXACT CONFIGURATION

Materials & structural scope

No separate materials-only record captured. This does not mean the system lacks materials certification.

Unlisted contaminants have no captured claim here. An absent catalog claim does not prove absence of certification.

REPLACEMENT BUDGET

Annual filter cost

$79.90365 gallons / year · all 1 replacement item
  • OB03 · 10 units / year$79.90

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.
