Tru Pro All-In-One Shower Filter w/ Extra Replacement Filter
Lower-concern shower filter, but Berkey makes no PFAS disclosure, standard activated carbon is unlikely to contain PFAS.
Berkey's shower filter uses activated carbon and mineral media, materials not typically associated with PFAS contamination. However, Berkey provides no public PFAS testing data or transparency claims. The housing material and any coatings are not clearly disclosed, leaving a modest gap in assurance.

The full breakdown
What it's made of and why it matters
The Tru Pro uses activated carbon as its primary filtration media, a porous material that adsorbs chlorine, some volatile organic compounds, and odor-causing substances through a process of molecular binding rather than mechanical sieving. The plastic housing is almost certainly polypropylene or a similar commodity resin common in filter bodies. Activated carbon itself is inert once manufactured and does not leach into water under normal shower conditions; the main durability concern is channeling (water finding paths around the media) once the filter becomes saturated or compressed after months of use.
The brand's record and disclosure
Berkey, known for its gravity-fed water pitchers, maintains a reputation for basic filtration without third-party certification or published material safety data sheets for this specific product. The brand makes no public disclosure of PFAS testing, material sourcing, or housing composition, which is standard silence in the shower filter market rather than a red flag. No recalls or safety complaints specific to the Tru Pro are documented in public records. Berkey's larger pitchers have faced criticism for lacking NSF certification and independent testing, but the lower complexity of this shower filter reduces those concerns.
How it compares in its category
Most shower filters use activated carbon, KDF (kinetic degradation fluxion copper-zinc media), or combinations thereof; this product is in the mainstream approach. Filters branded as 'all-in-one' typically offer modestly wider contaminant capture than single-media designs but still do not remove minerals or all disinfection byproducts. The inclusion of a replacement filter adds convenience and reduces the common mistake of extended filter use beyond effective life. Price-wise, it sits in the mid-market for residential shower filters, neither premium nor budget-bin.
If you buy it
Replace the filter every 6 to 12 months depending on water hardness and flow rate; most users notice reduced water pressure as a signal of saturation. Flush the new filter briefly before installation to clear any loose carbon dust. Store replacement filters in a dry location away from direct sunlight to prevent microbial growth in the media. Do not use if the housing shows cracks or the connection to your showerhead feels loose, as bypass reduces filtration effectiveness.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Bacterial regrowth in saturated filter media
Activated carbon, once saturated with water and organic matter, can support biofilm growth if filters are not replaced on schedule or if the filter remains damp between uses. Shower filters left standing in warm bathrooms face higher risk than other water filters.
Plastic housing leachables (BPA, phthalates)
Shower filter housings are not typically made from polycarbonate or vinyl and are unlikely to contain BPA or phthalates under normal formulation. No documented leaching from polypropylene shower filter bodies at tap water temperatures has been reported; however, Berkey does not disclose the specific resin type or additives.
Activated carbon dust inhalation during installation
Loose carbon particles may be released when a new filter is inserted, especially if not flushed first. Inhalation of fine carbon dust is a low-level nuisance exposure in a wet bathroom environment but not acutely hazardous in typical residential use.
Water quality claims beyond actual filtration scope
Shower filters marketed as 'all-in-one' or 'complete' sometimes imply removal of all contaminants, but activated carbon alone does not remove minerals, bacteria, viruses, or heavy metals effectively. This is a marketing practice issue rather than a chemical hazard, but may lead to false sense of water safety.
Filter bypass and reduced effectiveness over time
Once the activated carbon becomes compacted or saturated, water may channel around the media rather than passing through it, reducing contaminant capture while water flow may still appear normal. Users cannot visually detect this degradation without pressure monitoring.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
