Replacement filters
Claims below apply to H-300 + H-300 as a complete configuration. Physical fit alone does not establish certified performance.
300 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 · Time-limit source
Mechanical claims do not carry a capacity rating. NSF listing footnotes require date codes from 1C38 and 1C48; confirm on your unit before relying on this record. Replace at least annually; change sooner at rated capacity, reduced flow or other manufacturer replacement indicators.
Reduction claims
Checked against the public NSF listing. 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
- H-300 · 2 units / yearPrice or schedule needed
An annual total is shown only when every replacement item has a price and at least one verified replacement limit.
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.
Checked model list, exact replacement identifier, certification statement, table columns and applicable footnotes against archived source. Mechanical claims do not carry a capacity rating. NSF listing footnotes require date codes from 1C38 and 1C48; confirm on your unit before relying on this record.
H-54, H-104, H-300, H-300-NXT and H-1200: replace annually or earlier at capacity/reduced flow. H-1200 requires both cartridges.
Public lookup permitted by robots.txt on access date. H-300 date-code conditions 1C38 and 1C48 apply. 372 addresses lead content, not contaminant reduction.
H-300: Price not verified. Pentair publishes distributor purchasing options rather than a direct-sale price. Enter a distributor quote for this exact genuine cartridge.
Manufacturer lists genuine replacement and distributor purchasing options, with no numeric direct-sale price. Different item numbers printed on the page are not silently treated as new certification aliases.
Follow the source document’s water-quality limits and conditions of use. Household filtration does not replace required disinfection.
