Premier Series AS-PR75AK Reverse Osmosis Water Filtration System with Chrome Faucet
Lower concern; RO systems typically use PFAS-free filter media.
Reverse osmosis membranes and activated carbon filters are inherently lower concern for PFAS. Chrome faucet coating and housing materials lack disclosed composition; no PFAS claims found.

What Premier Series AS-PR75AK Chrome Faucet is made of, ingredients and materials
This system uses a reverse osmosis membrane (typically a thin-film composite polymer) paired with activated carbon pre-filters. RO membranes are not applied as coatings to food-contact surfaces but function as a porous barrier inside a sealed housing. The chrome faucet is a metal plating over brass or steel base; chrome itself is not a leaching concern under normal use, but the underlying base material and any nickel in the plating warrant consideration if the coating degrades. No glazes, ceramics, or non-stick coatings are involved, so lead, cadmium, or Teflon-type coating fume risks do not apply to this appliance.
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.
Bacterial and biofilm growth in storage tank and membrane housing
RO systems store treated water in a tank where stagnant conditions favor bacterial colonization if filters are not replaced on schedule or the system sits unused. No UV sterilization stage is documented for this model, increasing reliance on chemical-free maintenance discipline.
Water stagnation if tank remains pressurized between uses
If the system's storage tank is not drained or flushed after extended periods without use, water can become a culture medium for microorganisms. This is a maintenance hazard, not a product defect, but systems without automatic shutoff valves require more user diligence.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Nickel leaching from chrome-plated faucet
Chrome plating itself does not leach; however, if plating wears or cracks, the nickel content of the underlying alloy (common in brass) may contact water. No corrosion or plating failure has been reported for this faucet model, but durability depends on water pH and mineral content.
Plastic housing and tubing off-gassing or degradation
The system uses food-grade plastic tubing and housings common to all RO systems; no formaldehyde resins, BPA, or phthalates are typically used in RO filter housings or membranes, and no recalls or contamination reports are on record for this brand.
Leaching from silicone seals and compression fittings
Silicone seals are generally inert; however, low-quality compression fittings can corrode or fail, potentially introducing metal particles or mold into the treated water. Maintenance and inspection of fittings are the primary controls.
How is this PFAS grade calculated?
The brand's record and disclosure
Aquasure is a subsidiary of iSpring Group, a manufacturer with no major documented product recalls, health violations, or safety certifications highlighted in public records for this model line. The brand does not publish detailed material composition or third-party testing for non-PFAS contaminant removal specificity. No prominent certifications (NSF, WQA) are listed for the AS-PR75AK in available product literature, though the RO membrane itself is a standard technology. Disclosure is minimal but absence of controversy does not indicate comprehensive transparency.
How it compares in its category
Reverse osmosis systems are among the most effective at removing broad contaminant classes (bacteria, heavy metals, dissolved salts, some organics) compared to simple carbon or pitcher filters. However, they require regular filter replacement and tank maintenance to prevent biofilm and bacterial colonization; this maintenance burden is higher than passive alternatives. Chrome faucets on budget-tier RO systems are common and generally durable, though they perform no filtration function and their longevity depends on installation quality and water hardness. Premium systems often include additional stages (UV, remineralization) not present here.
If you buy it
Replace the sediment and carbon filters every 6-12 months and the RO membrane every 2-3 years, or sooner if water pressure or output drops; unmaintained systems can cultivate bacterial biofilm in the tank. The chrome faucet should not be subjected to abrasive cleaners or high-impact contact; if plating cracks, cease use and replace rather than risk exposure to base metals. Store the system in a temperature-stable location (avoid freezing); the membrane can crack if water inside freezes. Flush the system monthly if it sits unused, and monitor for leaks around compression fittings, which are common failure points.
