What Purafil does

Purafil is a United States-based environmental services and specialty manufacturing company that designs, produces, and supports gas phase (molecular) air filtration systems for industrial, commercial, healthcare, electronics, and municipal customers globally. Founded in 1969 and headquartered in Doraville, Georgia (USA), the company operates 9 manufacturing facilities and has been a subsidiary of Filtration Group Inc. since 2015, following earlier stints inside Kaydon Corporation (from 2005) and the SKF Group (from 2013).

The company's core technology is a proprietary chemisorption process in which spherical, porous pellets impregnated with reagents such as potassium permanganate convert targeted gaseous pollutants (including hydrogen sulfide, sulfur dioxide, nitric oxide, formaldehyde, chlorine, and ammonia) into harmless solids trapped inside the pellet. This chemistry underpins a portfolio of more than a dozen molecular media products (Purafil SP, SP Blend, Puracarb, Puracarb AM, Chemisorbant, CP Blend, Select CP Blend, Purafil Select, Purakol, AC Pellet, OdorCarb Ultra, Purafil CSO, MUA) protected by patents including the chemisorption process and Posi-Track module technology. Building on these media, Purafil offers drop-in filters (PuraGRID, MERV 13 PuraFilter, AOC PuraFilter), disposable modules (PK-12/PK-18, CK-12/24), capital equipment (Deep Bed, Tub, Parallel Bed, Vessel, Drum, Emergency Gas, and Chlorine Drum Scrubbers; Corrosive Air Systems; Positive Pressurization Units; Compressor Intake Filters; Side Access Systems), and monitoring products (OnGuard Smart with Modbus, CCC and CCC+ coupons). The offering is augmented by an ISO 17025:2017 accredited laboratory (A2LA certificate 4971.01) running 20,000+ analyses per year in 12 languages for coupon analysis, media life analysis, and room surveys, plus an ISO 9001 quality system.

Purafil generates revenue primarily through hardware sales of consumable molecular media (replacement cycles tied to application conditions) and built-to-order filtration equipment, supplemented by laboratory services and monitoring hardware. Pricing is quote-based rather than publicly disclosed, reflecting a consultative, application-engineered go-to-market model executed through a global network of 250+ factory-trained representatives and distributors serving approximately 70 countries, alongside direct enterprise phone and website sales (including a Pay Now option). The company is positioned as a category leader in gas phase filtration for corrosion control, odor control, and toxic gas scrubbing across electronics (data centers, semiconductor fabs, telecom), healthcare (hospitals, IVF labs), commercial and residential buildings (including museums), industrial and transportation settings (airports, refineries, pulp and paper), and water/wastewater treatment plants.
