Replacement filters
Claims below apply to OB43 + OB06 as a complete configuration. Physical fit alone does not establish certified performance.

Dagger-marked claims included only for the ten models named in the page 2 footnote. Microplastics is not dagger-marked. Use model number on the base; retail names can vary.
Reduction claims
WQA 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
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.
Annual filter cost
- OB06 · 4 units / year$79.96
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.
