Rensa Filtration acquires carbon filter specialist D-Mark

Rensa Filtration (formerly known as Air Filtration Holdings LLC) has bought Michigan-based D-Mark Inc, a manufacturer of molecular filtration products and proprietary owner of CarbonWeb® media and OdorGuard® products used in odour, gas and particulate removal applications.

D-Mark’s products include panels, pads, pleats, pleat inserts, rigid cells, ring panels, CarbonWeb roll media, “filled” filters for v-banks, bulk carbon and other filters for appliances and air cleaners.

“D-Mark’s ability to manufacture nonwoven carbon filled filter media is exciting and allows us to continue to expand the innovative product portfolio of Rensa Filtration,” said Brandon Ost, CEO of Rensa Filtration. “D-Mark founder and president, James Kasmark, has built an exceptional company with a reputation for advancing carbon technology to address customer needs with molecular filtration.”

“I knew that when it was time for me to sell my company I wanted the new owners to have a passion for filtration. I have known Brandon for many years and it is an excellent fit,” said Kasmark. “Combining the patented CarbonWeb process and technology with Rensa’s energy and spirit for innovation, along with a proven track record of the management team to introduce new products to the filtration market provides D-Mark the tools necessary to reach new levels.”

This is Rensa Filtration’s fourth acquisition in the last 15 months. Previous acquisitions include Viskon-Aire, Permatron and RoboVent.

Rensa Filtration, which was founded in 2017 by industry veteran Brandon Ost and private investment partners, says that it will continue to look to grow through acquisitions.
