Our verdict on the PUR Faucet Mount (PFM/FM)
The PUR PFM400H is a 0.52 gpm point-of-use faucet filter with a 100-gallon or three-month cartridge cycle, but it fits standard faucets only and does not filter microbes.[1][2]
Best for
- Homes that want point-of-use filtration directly from a faucet
- Cold-water supplies that stay within 20-100 psig and 34-82°F
Not for
- Pull-out or handheld faucets
- Microbiologically unsafe or unknown-quality water without adequate disinfection

Sources and data report: PUR Faucet Mount (PFM/FM)
Every figure above is taken from the highest-trust source that carries it and re-derived from that source by a separate check. How we verify product data.
What we could not establish, and why
| Field | Why it is blank |
|---|---|
| mechanism.treatmentMethods | PUR identifies activated carbon and ion exchange for faucet filters, but the product page and current performance data sheet do not publish an ordered treatment train; no stage order was inferred. |
| fit.bathroomsServed | PUR's product page, support material, manual, and performance data sheet do not size this point-of-use faucet device by bathroom count. |
| fit.householdSize | PUR publishes a 0.52 gpm service flow and filter capacity but no supported household-size range for PFM400H. |
| fit.roOutputGpd | PFM400H is a faucet-mount adsorption/ion-exchange product rather than a reverse-osmosis system, so PUR publishes no RO membrane output. |
| fit.roTankCapacity | PFM400H has no reverse-osmosis storage tank; the product page and manual publish no tank capacity. |
| fit.connectionSize | PUR supplies three adapters and offers additional adapters, but its current product page, support page, manual, and performance data sheet do not publish one nominal connection size for PFM400H. |
| fit.requiresElectricity | The system has a battery-powered filter indicator, but PUR does not publish this field in a way that cleanly distinguishes internal battery power from an external electricity requirement; no boolean was inferred. |
| fit.requiresDrain | PUR's installation steps show direct faucet attachment and no drain connection, but the manufacturer does not explicitly publish a requires-drain boolean; the record leaves it unasserted. |
| cost.msrp | PUR's product page does not publish an MSRP; only live retailer prices were found, so MSRP was not substituted with street price. |
| cost.wasteRatio | PFM400H is not a reverse-osmosis system and has no wastewater connection; PUR publishes no waste-to-product ratio. |
| cost.moneyBackGuarantee | PUR's warranty/registration page and product materials describe a limited warranty but no separate money-back guarantee with a stated term. |
| install.estimatedHours | PUR describes the attachment as tool-free and provides installation steps, but no official elapsed-time estimate is published; retailer review summaries were not converted into a manufacturer install time. |
| comparisons.familyCertNote | Live certifier listings support individual model entries, including PFM400H, but do not support extending one model's listing scope to every variant grouped in this record. |
| seo.cluster.primary.kd | The approved build-list row supplied no keyword-difficulty value for the primary query, and S2 did not replace the build-list metric with an estimate. |
| seo.verification | The verification loop stamps this field after independent verification; the initial research stage must leave it null. |
