What our pitchers are made of
Your water sits against the pitcher all day, every day, so the material is not a footnote. Epic pitchers and dispensers are crafted from BPA and BPS free, medical-grade Tritan. Here is what that means, how it has been tested, and where NSF certification actually applies.
The quick picture
Old-school clear plastic (polycarbonate) is literally built from BPA. Many BPA-free replacements quietly swap in cousins like BPS. Tritan, a copolyester made by Eastman in Kingsport, Tennessee, takes the third path: no bisphenol of any kind is used as a raw material, and none is formed as a manufacturing byproduct.
Eastman reports that BPA and BPS have never been used as raw materials in Tritan and are not formed as byproducts, that Tritan contains no ortho-phthalate plasticizers, and that it is not on California's Prop 65 list of chemicals requiring a warning.
After a 2011 paper reported estrogenic activity from many stressed BPA-free plastics, Tritan went through a third-party program spanning computer modeling, cell assays, and animal studies, published peer-reviewed in 2012 with no estrogenic or androgenic activity found. In 2013 a federal jury found the challengers' Tritan claims false and misleading, affirmed on appeal in 2014.
A pitcher is a system: the vessel and the filter inside it. The vessel is named materials, BPA and BPS free Tritan plus food-grade polypropylene with no ABS anywhere. The certified part is the filter: Pure XP and Nano XP are NSF certified to NSF/ANSI 42 and NSF/ANSI/CAN 372.
Why certification belongs on a materials page
Resin testing tells you about the plastic. Certification covers the filter doing the work: Pure XP and Nano XP are NSF certified to NSF/ANSI 42 for chlorine taste and odor plus material safety, and to NSF/ANSI/CAN 372 for lead-free materials. The vessel is the named-materials part, Tritan and food-grade polypropylene with no ABS, so nothing on this page asks you to take anyone's word for it, including ours.
The simple checklist
Inside the build
Tritan is a copolyester: clear like glass, shatter-resistant, and stable through daily use, which is why it also shows up in medical devices and baby bottles. In an Epic pitcher it pairs with food-grade polypropylene components and the CoreXchange filter media doing the actual contaminant work.

Fast decision guide
Every Epic pitcher and dispenser is crafted from the same BPA and BPS free medical-grade Tritan. The decision left is the format your kitchen will actually use.
Quick answers
Tritan is a BPA-free and BPS-free copolyester that is widely used for drinkware, food storage, and medical devices. Its maker reports that no bisphenols are used as raw materials or formed as byproducts, that it contains no ortho-phthalate plasticizers, and that accredited third-party labs found it free of estrogenic and androgenic activity. It is accepted for food contact by regulators, and it is the material we chose for Epic pitchers and dispensers.
No. Many products labeled BPA-free are made with substitute bisphenols such as BPS, which raise similar questions. Tritan is different: no bisphenol of any kind is used in its chemistry. If a label only says BPA-free, it is worth asking what the material actually is.
Yes, and the dispute was resolved in court and in the literature. A 2011 paper reported estrogenic activity from many BPA-free plastics under stress. Eastman responded with a third-party testing program spanning computer modeling, cell assays, and animal studies, published peer-reviewed in 2012, finding no estrogenic or androgenic activity. In 2013 a federal jury found the labs' claims about Tritan false and misleading, and the verdict was affirmed on appeal in 2014.
Tritan as a material tolerates dishwashers without warping, but our care guidance is simpler and safer for the whole product: hand wash the reservoir, pitcher body, and spout in warm soapy water and air dry. The lid with the digital timer should never go in the dishwasher or be soaked; wipe it with a damp cloth.
Certain Tritan formulations are supplied for use in medical devices, where materials must meet demanding standards for contact and durability. Epic pitchers and dispensers are crafted from this BPA and BPS free medical-grade Tritan for the parts your water touches.
No. Epic pitchers are built with BPA and BPS free Tritan and food-grade polypropylene components, with no ABS plastic. The Pure XP and Nano XP filters inside are NSF certified to NSF/ANSI 42 and NSF/ANSI/CAN 372. The vessel itself is not NSF certified; its materials are named instead.
The filters. Pure XP and Nano XP filters are NSF certified to NSF/ANSI 42 for chlorine taste and odor reduction and material safety, and to NSF/ANSI/CAN 372 for lead-free materials. The pitcher vessel itself is not NSF certified: its story is named materials, Tritan plus food-grade polypropylene. Named materials on the vessel plus certification on the filter is the combination worth looking for.

Tritan material background is summarized from Eastman's published Tritan safety testing documentation (no BPA or BPS used as raw materials or formed as byproducts; free of ortho-phthalate plasticizers; not listed under California Prop 65; third-party tested free of estrogenic and androgenic activity). The 2012 peer-reviewed monomer study is Osimitz et al., Food and Chemical Toxicology. The litigation history is summarized from the Fifth Circuit's 2014 opinion in Eastman Chemical Co. v. PlastiPure. NSF standards background is summarized from NSF consumer resources. Tritan is a trademark of Eastman Chemical Company; Epic Water Filters is not affiliated with Eastman. Product material and certification claims are based on Epic Water Filters published product information. NSF certification and independent contaminant-reduction testing are not the same thing; review each product page and testing documentation for exact standards, claims, and contaminant lists. Product performance can vary by water quality, usage, and filter replacement schedule. Last updated August 2026.
