Manufacturer's Warranty — Abatement Technologies

Abatement Technologies products are sold with the manufacturer's warranty. All warranty claims are handled directly by Abatement Technologies — HEPA Filter Sales, LLC does not administer or extend manufacturer warranties. Contact us if you need assistance reaching the manufacturer's warranty or support team.

Use of non-OEM replacement filters or parts voids the manufacturer warranty and all performance claims on Abatement Technologies equipment.

We want every order to go smoothly, and if something is not right we want to make it right. At the same time, for the health and safety of everyone — our team, other customers, and the facilities these products are used in — we cannot resell opened or used filtration and air quality products. Our policy below is built around that reality. If you have any questions about a product before ordering, please reach out — we would rather help you get the right thing the first time than deal with a return after the fact.
