Numhew 22 oz. Water Filter Pitcher
Skip until brand discloses filter composition and pitcher polymer type.
Numhew/NewWays provides no public information about PFAS use in this pitcher or its replacement filters. Water filter pitchers often use activated carbon (lower concern), but the pitcher body material and any proprietary filter coatings remain undisclosed.

The full breakdown
What it's made of and why it matters
The Numhew pitcher is plastic housing (polymer type unspecified by brand) with a replaceable activated carbon cartridge. Activated carbon itself is inert and safe, but the pitcher's plastic composition determines whether it can leach chemicals into filtered water, especially if exposed to heat or acidic water. Without disclosure, you cannot confirm whether the housing is polypropylene (safer, stable) or a lower-grade plastic prone to degradation.
The brand's record and disclosure
NewWays has not publicly disclosed the pitcher's polymer material, cartridge composition, or PFAS testing results for either component. No major recalls or safety controversies are on record for this model. The brand's silent stance on filter composition is a red flag in an industry where PFAS-laden activated carbon and non-compliant housing plastics have been documented in competing products.
How it compares in its category
Pitcher filters like this occupy the low-cost, low-maintenance segment. Compared to brands like Brita or PUR (which disclose BPA-free housing and publish cartridge testing), the Numhew offers no third-party certification or transparency. It performs standard mechanical filtration (chlorine, taste, odor reduction) but cannot remove all contaminants or confirm safety margins for long-term daily use.
If you buy it
Replace cartridges every 2-3 months or 40 gallons (whichever comes first) to prevent bacterial growth and carbon saturation. Do not fill with hot water or store near heat sources, as plastic degradation risk increases with temperature. Rinse the pitcher weekly and inspect for cloudiness, cracking, or discoloration, which signal polymer breakdown. Request polymer and filter composition from NewWays before purchase if possible.
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.”
Plastic leaching (unknown polymer)
Pitcher material is not disclosed; if it is recycled or low-grade polycarbonate, BPA or other bisphenols may leach into stored water over months. Polypropylene (safer) is standard but unconfirmed here.
Activated carbon cartridge contamination or saturation
Pitcher-style filters rely on user memory for replacement; overused cartridges harbor bacteria and algae, especially in warm environments. NewWays provides no automated alerts or shipping reminders.
Housing degradation over time
Plastic pitchers crack, cloud, or leach microplastics after 1-2 years of daily use, particularly if filled with chlorinated or acidic tap water. No durability testing or warranty data from NewWays is published.
Bacterial regrowth in filter housing
If pitcher sits unused for days or stored in warm kitchens, stagnant water in the cartridge chamber encourages microbial growth. Activated carbon does not sterilize; it only adsorbs contaminants.
Filter composition unknown (including PFAS risk in cartridge)
Activated carbon cartridges from some manufacturers have tested positive for PFAS carryover or use PFAS-coated filter media. NewWays' silence prevents assessment of this hazard class, elevating category-wide risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
