ECO-PFAS(ACF)
FILTER
The world's first eco-friendly PFAS filtration filter based on upcycled oyster shell media.
Beyond long-chain PFOA & PFOS — now extending to short-chain PFHxS, PFHpA, HFPO-DA(GenX) & PFBS.
The industry-first filter with certified removal across all 6 PFAS compounds.
An Innovative Solution to Break the Limits
of Conventional Filters
Conventional activated carbon filters are effective for PFOA and PFOS, but are largely ineffective against
short-chain PFAS compounds such as PFHxS, PFHpA, HFPO-DA (GenX), and PFBS.
The WACO ECO-PFAS(ACF) FILTER overcomes this limitation using a proprietary oyster shell-derived ACF adsorbent,
achieving verified removal of a broader range of PFAS substances.
- PFOA — Removable
- PFOS — Partially Removable
- PFHxS — Not Removable
- PFHpA — Not Removable
- HFPO-DA (GenX) — Not Removable
- PFBS — Not Removable
※ Short-chain PFAS compounds are extremely difficult to capture through physical adsorption by activated carbon alone.
- PFOA — 100% Removal (Not Detected)
- PFOS — 100% Removal (Not Detected)
- PFHxS — 96.4 ~ 100% Removal
- PFHpA — 100% Removal (Not Detected)
- HFPO-DA (GenX) — 100% Removal (Not Detected)
- PFBS — 100% Removal (Not Detected)
※ All 6 PFAS compounds verified by KCL (Korea Conformity Laboratories) official test reports.
Oyster Shell–Derived ACF Material:
Dual Adsorption Mechanism

outstanding adsorption capacity.
short-chain PFAS through ion exchange and chemical bonding as the secondary stage — targeting PFHxS and
PFHpA that conventional filters miss entirely.
