Premier Series Reverse Osmosis System with Chrome Faucet AS-PR75AK
Skip until brand discloses filter and membrane PFAS status.
Reverse osmosis systems use carbon and membrane filters unlikely to contain intentional PFAS, but chrome faucet coating and filter material sourcing lack public disclosure. No third-party verification found.

What Premier Series Reverse Faucet AS-PR75AK is made of, ingredients and materials
This system uses a reverse osmosis membrane (typically thin-film composite polyamide), activated carbon cartridges (porous coconut or coal-based), and a chrome-plated brass faucet. The membrane and carbon are contact surfaces for drinking water, so their manufacturing residues and leaching potential matter directly to what you consume. Chrome plating on brass faucets is standard in the category and poses minimal risk under normal use, but the polymer membrane and carbon quality determine whether contaminants are removed effectively and whether the filtration media itself sheds particles or chemicals into treated water.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Thin-film composite RO membranes and some activated carbon sources have been reported to contain or leach PFAS compounds. Aquasure provides no published test data or certification confirming PFAS absence, leaving this risk unquantified for this specific product line.
Source, ATSDR ↗Bacterial or mold growth in filter cartridges
If cartridges are not replaced on schedule or if the system sits unused for extended periods, stagnant water in the pre-filter or post-storage tank can support microbial growth. This is a maintenance issue rather than a material defect, but failure to follow replacement intervals increases risk.
Off-gassing or particle shedding from new cartridges
New activated carbon filters may release fine carbon dust or residual manufacturing solvents during initial use. Flushing the system for 5, 10 minutes before consuming treated water is a common best practice and is typically recommended in product manuals.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Leaching from chrome faucet plating
Chrome plating on brass is a standard, regulated finish in potable water faucets. No specific recalls or documented leaching events are on record for Aquasure faucets under normal use conditions. Risk is low if the faucet is not subjected to extreme temperatures or corrosive conditions.
Polymer degradation in membrane or housing under prolonged storage or temperature stress
Polyamide RO membranes are stable under normal operating conditions (cold water, neutral pH), but are sensitive to heat, chlorine, and extreme pH. No specific failure or leaching records exist for Aquasure units under home use, but improper storage or water quality can shorten membrane life and trigger degradation.
How is this PFAS grade calculated?
The brand's record and disclosure
Aquasure does not publicly disclose PFAS status in its membranes, carbon, or replacement filters, which is a significant transparency gap given that PFOA and other fluorinated compounds have been detected in some commercial RO membranes and activated carbon sources. The brand holds no known third-party certifications (NSF, WQA) that would independently verify contaminant removal claims or material purity. Without certification or direct PFAS testing data from Aquasure, buyers cannot confirm whether this system removes or potentially introduces PFAS into treated water.
How it compares in its category
Most consumer RO systems in this price range share the same material architecture (polyamide membrane, carbon pre-filters, chrome faucets) and similar disclosure gaps. NSF-certified competitors (e.g., iSpring, Watts) provide third-party verification of membrane purity and contaminant removal claims. Aquasure's lack of certification does not necessarily mean lower quality, but it removes an independent safety checkpoint that higher-scrutiny brands provide. Budget RO systems universally require regular filter replacement and maintenance; this model is typical in that respect.
If you buy it
Replace cartridges (pre-filters and RO membrane) on the manufacturer's schedule, typically every 6, 12 months for carbon and every 2, 3 years for the membrane, to prevent bacterial colonization in stale filter media and to maintain flow rate and contaminant removal. Do not expose the faucet or connections to temperatures above 50°C (122°F), as this can degrade seals and cartridge housing. Store replacement cartridges in a cool, dry place before use. If you have private well water or high sediment content, pre-filtration upstream of this unit will extend membrane life.
