Capella reverse osmosis
System model RC250
Capella reverse osmosis uses RF-30, RF-50. Replacement cycles and source-specific performance limits are listed below.
Use the exact documented model and replacement configuration. Similar model names do not establish equivalent claims.

Replacement filters
Claims below apply to RC250 + RF-30 + RF-50 as a complete configuration. Physical fit alone does not establish certified performance.
300 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
No gallon limit in captured instructions / 24 months. The captured maintenance instructions specify a time interval for this stage; no stage-specific gallon limit was found. Capacity / component source
Carbon filters and the membrane have different replacement cycles. Pentavalent arsenic performance requires the stated feed-water chemistry. This entry preserves the older manufacturer PDS; verify current source revisions before purchase.
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
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
- RF-30 · 2 units / year$139.98
- RF-50 · 1 units / year$79.99
Some stages have only a published time or gallon limit. This estimate uses the captured limits; follow flow, indicator and other earlier replacement triggers in the instructions.
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.
Evidence & review
Reviewed 2026-09-21 · Codex document review. Document review, not independent laboratory testing.
Matched the exact system, replacement elements, claim-specific standard and operating limits against the archived source. This is an assisted document review, not laboratory testing or independent human certification.

One-time prices. RF-20 and RF-30 are complete three-filter kits, not three identical cartridges. Individual Cypress filter schedules take precedence over conflicting bundle teaser text.
