D-Mark: The Carbon Filter Specialists
For over 50 years, innovation in the design and development of activated carbon filtration products has been our hallmark.
D-Mark is located at 130 N. Groesbeck Highway, Mt. Clemens, MI 48043, and can be contacted directly at 586-949-3610 or dmark@dmarkinc.com.
Founded in 1970, D-Mark has been a pioneer in molecular air filtration for over five decades. We manufacture our proprietary CarbonWeb® activated carbon media, an advanced adsorptive material engineered to remove odors, gases, vapors, and chemical pollutants with exceptional efficiency. Unlike loose-fill or pelletized carbon, CarbonWeb’s non-woven structure offers higher surface area, lower pressure drop, and longer service life, making it ideal for a wide range of HVAC, industrial, and commercial applications.
Improving indoor air quality has long been one of the HVAC industry’s greatest challenges — and D-Mark’s CarbonWeb technology continues to set the standard. While the Air Movement Industry has been very effective in the areas of human comfort and the removal of particulates – chemical pollution, obnoxious odors and harmful smoke must also be removed. From capturing harmful VOCs and diesel exhaust to mitigating wildfire smoke and nuisance odors, our products help create cleaner, safer, and more comfortable environments through improving indoor air quality.
In 2018, Rensa Filtration acquired Michigan-based D-Mark, enhancing access to leading molecular filtration technologies across its family of filtration companies. Today, D-Mark’s CarbonWeb filters are trusted in airports, research facilities, hospitals, laboratories, restaurants, and other critical environments where air quality truly matters.
Our mission is to provide a complete line of quality, thin bed adsorptive products for odor and pollution control plus the knowledge to apply them effectively.
Thank you for the amazing service! The last time we sent you a PO, you were able to get us all the filters 2 days later. You make us look like heroes. I always tell people that your operation is the most impressive I've seen with customer service and lead times.
