Odor Control Products

Filtration and neutralization products that keep mercaptan odor contained, on site and in the field.

EZ Carb activated carbon filter drum used for odorant vapor capture at MRR odorization stations

MRR manufactures the consumables that keep mercaptan odor contained and neutralized at odorization stations, in maintenance bays, and out in the field. EZ Carb activated carbon filters and EZ Carb™ passive filters capture odorant vapor before it reaches the atmosphere, in active (blower-driven) and passive (vent-line) configurations. DEOmer neutralizes mercaptan chemically at the source, while Mask-O covers the smell with an orange scent when full decontamination isn't required. Both liquids work across the same temperature range year-round, with no separate winter formulation to stock. Every product ships in sizes from a single spot treatment up to a full drum for larger cleanup or replacement.

Complete Odor Control

Capture

Activated carbon and passive filters trap odorant vapor before it reaches the atmosphere. Both configurations use the same carbon media, sized for active or vent-line service.

Neutralize

DEOmer reacts with mercaptan to break it down chemically, eliminating odor at the source. It works across the same temperature range year-round, with no winter formulation to stock.

Mask

Mask-O covers the smell with a fresh orange scent when full neutralization isn't needed. It's a lower-cost option for routine maintenance and field work where speed matters most.

EZ Carb™ Activated Carbon Filters

Active, blower-driven filtration pulls odorant vapor through activated carbon media before it's released to atmosphere. Sized for continuous duty at odorization stations and compressor sites where airflow needs to be controlled.

EZ Carb™ Passive Filters

Passive, vent-line filtration captures odorant vapor with no blower required, ideal for smaller relief and vent points. Uses the same carbon media as the active units, sized for lower-flow applications.

DEOmer

A liquid neutralizer that reacts with mercaptan to eliminate odor chemically at the source, rather than masking it. Works across the same temperature range year-round, so there's no separate winter formulation to stock.

Mask-O

An orange-scented liquid that covers mercaptan odor for routine maintenance and field work where full chemical neutralization isn't required. A lower-cost option that still keeps odor complaints down on site.
