FilterONE services

FilterONE USA™ is a division of Parkson which specializes in maintenance, installation, turnkey refurbishments and service contracts for municipal and industrial water and wastewater treatment equipment. With in-house design, engineering and installation capabilities, we can provide customers with a lower cost alternative to a complete system replacement. We provide site visits and estimates to get your system running like new and can provide original equipment manufacturer parts and components. 

Established in 2003 and with hundreds of years of combined experience in the water and wastewater industry, we have a wealth of experience and industry knowledge. FilterONE is staffed by service engineers who have completed hundreds of on-site rebuilds and refurbishments on all types of equipment. It is our philosophy that specialized work must be completed by experienced professionals who can complete a complex mechanical task with the least amount of supervision and so we do not utilize personnel from labor pools or temporary labor. 

We can assist you with completing rebuilds on-site, instead of shipping equipment back to the factory, as it greatly reduces equipment downtime and minimizes labor needed by plant personnel while equipment is out of service.

Looking for service assistance? We’re here to help.
