The Odorknocker Model RX is a great choice as an alternative to the Parson Odoreater Manhole Insert and is available to fit almost any manhole. Our media deals with H2S by chemical reaction instead of absorption making it easier to dispose of. Our media continues to work when wet and its OSHA and EPA approved.

Likewise the Rainstopper is a great choice as an alternative to the Parson Manhole Insert for situations that require the prevention of inflow.
