What Brita Basic On Tap Faucet Water Filter is made of, ingredients and materials
The Brita Basic On Tap uses granular activated carbon as its filtration medium, which does not contain PFAS and is a well-established water treatment material. The filter cartridge itself is designed to trap chlorine taste/odor and some dissolved contaminants. The faucet housing is plastic (polymer type unspecified by Brita), a cost-driven choice typical in budget faucet filters that avoids the metal corrosion risks of all-metal designs but introduces potential for plastic leaching under prolonged hot-water contact.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Plastic housing leachables (unspecified polymer)
Brita does not publicly specify the polymer type (polypropylene, ABS, etc.) used in the On Tap housing. Contact with hot water or prolonged stagnation could theoretically leach small amounts of BPA or other additives, though no reported incidents exist for this product.
Bacterial and mold growth in filter cartridge
Any activated-carbon water filter is susceptible to microbial colonization if not replaced regularly or if water stagnates in the cartridge. This is a maintenance issue rather than a manufacturing defect, but critical to prevent.
Reduced filtration capacity over time
Activated carbon filters have finite adsorption capacity; chlorine and organic contaminant removal decline after 2-3 months of typical household use. User may not detect degradation without testing, leading to false confidence in water safety.
Filter media escape (micro-particles)
If the filter cartridge cracks or housing seal fails, activated carbon particles could enter drinking water. This is rare but possible with physical damage; inspect cartridge before installation.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
This filter system does not address lead or copper in source water; it is designed for taste and odor only. If home plumbing contains corroded brass fittings or solder, this filter will not remove those contaminants.

The brand's record and disclosure
Brita has not made public statements specific to PFAS content in this product line or housing materials. The company holds NSF certification for some pitcher and replacement filter products, but certification status for the On Tap faucet system is not widely documented in accessible sources. No major recalls or contamination incidents specific to this faucet filter model are on record; Brita's general reputation in water filtration is established but transparency on polymer composition is limited.
How it compares in its category
Budget faucet filters like this one typically prioritize ease of installation and cost over material transparency. Most competing on-tap systems (PUR, Aqua-Pure, store brands) use similar unspecified plastic housings and activated carbon, making this a standard-tier product. Advantage over pitcher filters is convenience; disadvantage is less filterability per cartridge volume and higher per-gallon cost. Premium faucet systems sometimes specify housing material and include additional filter stages.
If you buy it
Replace cartridges every 2-3 months or per manufacturer guidance to prevent bacterial biofilm growth inside the filter and housing. Avoid prolonged exposure of the plastic housing to water hotter than 100F (38C) to minimize any risk of polymer leaching. Do not rely on this filter alone for water containing bacterial, viral, or heavy-metal contamination; activated carbon is primarily effective for chlorine, taste, and some organic compounds. Flush the system with running water for 5 seconds before use after cartridge replacement.
