Perfect Solutions for Remote Locations

No electricity or water hook-up required!

Our small biofilters are designed as passive biofilters (without a fan) to treat small waste air streams contaminated with hydrogen sulfide (H2S) and other organic odors from sewer manholes, vent pipes and force main air release valves.

These biofilters are perfect for installations in remote locations as they don’t require water or electricity hook-ups and will perform without the need for maintenance for several years.
Stop odor complaints without adding maintenance!

These are the most cost-effective long-term odor control solutions for remote locations.

Bioteg Manhole Biofilter

The Bioteg Manhole Biofilter is a specially designed manhole insert to biologically remove odors and H2S from sewer manholes. The insert is custom-designed to perfectly fit in any manhole, while its stable HDPE and stainless steel construction will prevent it from breaking and falling into your manhole, minimizing risk for clogged sewer lines. The Manhole Biofilter can be installed easily within a matter of seconds and is just as easily removed for access to the manhole.

The filter also has a water reservoir at the bottom that can be filled manually to help maintain the proper moisture level in the biofilter.
