Flexible and Affordable Modular Cleanroom Solutions

Cleanrooms come in all shapes and sizes incorporating many attributes depending on the applicable industry. Historically, these rooms were large and “stick built” making expansion, retrofitting or HVAC modifications complex and disruptive to on-going operations.

The Modular design has been well received and especially by startups or smaller companies needing an affordable option to the high square footage price of conventional Cleanroom construction. Modular Cleanrooms are also used at larger manufacturing facilities for a myriad of ancillary operations where less critical tasks still needing a clean or controlled environment are performed.

Modular designs offer a wide variety of options similar to stick-built cleanrooms but can be easily installed, expanded, retrofitted or moved offering a high degree of flexibility and value.

While One Source Environmental does not directly manufacture these products we work with exceptional manufacturers with proven track records and work as an intermediary and to provide our own branded FFUs, design assistance and construction services.
