PUR PPT111W (PUR PLUS 11-Cup, PPF951K filter)
Pros
- Certified for Total PFAS under NSF/ANSI 53
- 97% total PFAS removal in lab testing
- Removes lead, arsenic, uranium and microplastics
- Moderate annual filter cost
- Leaves minerals and pH alone
Cons
- Slow, about 30 to 34 minutes per gallon
- TechGearLab had the flip-top lid break
- Small fill opening

The strongest mix of certification, lab results and running cost in this group. It is slow and the lid is a weak point, but it is the pitcher most households should buy.

Pros
- Same Total PFAS-certified filter as our top pick
- 30-cup capacity
- Spigot dispensing
- Moderate filter cost
Cons
- Not lab-tested for PFAS on its own
- Some listings describe only lead and microplastics
- A 40-gallon filter goes fast in a big household
A sensible high-capacity alternate. Buy it for convenience, not because it filters better than the pitcher.
