Top 10 Air Pollution Control System Suppliers in Canada in 2025

Founded in 1995, EcoClean Systems Canada has been a cornerstone of Canada’s industrial air purification scene for nearly 30 years. What started as a small team of engineers in Vancouver has grown into a national leader, specializing in custom air pollution control solutions for heavy industries. Their sweet spot? Systems tailored for lead acid battery recycling equipment and li battery recycling equipment—two sectors where precision in capturing particulates and toxic gases is non-negotiable.

“We don’t just build filters—we build barriers between harmful emissions and the air,” says Maria Gonzalez, EcoClean’s chief technology officer. “Take lead acid battery recycling: during the breaking and separation process, sulfur dioxide and lead dust are major concerns. Our air pollution control system equipment uses a three-stage filtration process—electrostatic precipitation to catch large particles, activated carbon adsorption for gases, and HEPA filters for the finest residues. We recently installed this setup for a Toronto-based recycler, and within three months, their emissions dropped by 98%. The plant manager told us, ‘We used to get complaints from the neighborhood; now we get thank-you notes.’”

EcoClean’s edge lies in their ability to adapt. Unlike one-size-fits-all systems, they start with a site audit, mapping out emission hotspots, then design a system that integrates seamlessly with existing equipment. Their 24/7 monitoring service, which uses IoT sensors to adjust filtration in real time, has made them a favorite among companies aiming for zero-emission goals. With clients across Canada and partnerships with major battery manufacturers, EcoClean isn’t just keeping up with the industry—they’re setting the bar.

GreenAir Technologies burst onto the scene in 2008, and they’ve been disrupting the status quo ever since. Based in Montreal, this company made a name for itself by focusing on energy efficiency—proving that clean air doesn’t have to come with a sky-high electricity bill. Their claim to fame? A hybrid system that combines thermal oxidation with regenerative heat recovery, specifically designed for circuit board recycling equipment and refrigerator & ac recycling machines equipment.

“Circuit board recycling releases a cocktail of volatile organic compounds (VOCs) and heavy metals like cadmium and mercury,” explains Jean-Pierre Dubois, GreenAir’s founder. “Traditional incineration systems burn these off, but they’re energy hogs. Our system captures the heat from oxidation and uses it to power the next cycle—cutting energy use by 40%. For a Quebec-based circuit board recycler processing 2,000 kg/hour, that translates to $60,000 in annual savings. Plus, the VOC destruction efficiency is 99.9%, so they’re not just saving money—they’re protecting the St. Lawrence River valley from pollution.”

What really sets GreenAir apart is their commitment to small and medium-sized enterprises (SMEs). Many air pollution control systems are priced for large corporations, but GreenAir offers modular setups that can scale as a business grows. “A startup recycler in Calgary bought a basic unit from us in 2019; now they’re a national player with five locations, and we’ve upgraded their systems each step of the way,” Dubois adds. “We grow with our clients—that’s how we build trust.”

When PurifyWorks Inc. opened its doors in Edmonton in 2012, they had a mission: to make air pollution control accessible to remote and northern communities. In places like Fort McMurray or Yellowknife, where industrial operations are far from urban centers, getting reliable equipment and service can be a nightmare. PurifyWorks solved that by designing rugged, low-maintenance systems that thrive in harsh climates—perfect for metal melting furnace equipment and scrap cable stripper equipment operations common in resource-rich regions.

“We once installed a system for a nickel mine in Nunavut,” recalls CEO James Chen. “Temperatures there ｄｒｏｐ to -40°C, and parts can freeze or crack. Our systems use heated enclosures and lubricants rated for extreme cold, so they run smoothly year-round. The mine’s melting furnace used to emit thick black smoke; now, the only thing coming out of the stack is clean air. The Inuit community nearby told us, ‘For the first time, our kids can play outside without coughing.’ That’s the moment you remember why this work matters.”

PurifyWorks also prides itself on speed. Their “Rapid Deploy” program guarantees system design, delivery, and installation in under 60 days—a lifesaver for companies facing tight regulatory deadlines. With a network of service hubs across Alberta, Saskatchewan, and Manitoba, they offer same-day repairs, ensuring downtime is never more than a blip. For businesses in remote areas, that kind of reliability is priceless.

CleanBreathe Solutions, based in Halifax, is all about innovation—specifically, using AI to make air pollution control smarter. Founded in 2015 by a team of computer scientists and environmental engineers, this company combines cutting-edge machine learning with tried-and-true filtration technology. Their flagship product, the SmartFilter AI, is revolutionizing how air pollution control system equipment operates, especially in dynamic environments like cable recycling equipment and motor recycling machines equipment.

“Cable recycling is unpredictable,” explains Dr. Leanne Patel, CleanBreathe’s AI research lead. “One hour you’re processing copper cables, the next aluminum, and each releases different emissions. Traditional systems run at full blast all the time, wasting energy. SmartFilter AI monitors emissions in real time—using sensors to detect particle size, gas composition, and concentration—then adjusts fan speeds, filter pressure, and chemical injection rates on the fly. We installed this at a cable recycler in New Brunswick, and they saw a 35% reduction in energy use and a 20% longer filter lifespan. The system even sends alerts if something’s off, like a clogged filter, so issues get fixed before they become problems.”

CleanBreathe’s focus on data has also made them a hit with sustainability teams. Their cloud-based dashboard tracks emissions over time, generating reports that help companies measure their carbon footprint and prove compliance to regulators. “A client in Nova Scotia used our data to apply for green tax credits—they saved $120,000 in the first year,” Patel adds. “It’s not just about cleaning air; it’s about turning data into dollars and sustainability.”

For PureFlow Environmental, based in Winnipeg, air pollution control is personal. Founded in 2001 by David and Sarah Liu, whose family suffered from respiratory issues due to industrial pollution in their hometown, the company’s mission is “Clean air for every workplace, every community.” They specialize in systems for small to mid-sized operations, with a focus on wet process equipment and dry process equipment—two methods common in circuit board recycling equipment and lamp recycling equipment.

“Smaller recyclers often get overlooked,” Sarah Liu says. “They can’t afford million-dollar systems, but they still need to meet emissions standards. That’s where we come in. Our compact scrubber systems, for example, are designed for wet process circuit board recycling. They use a water-based solution to trap heavy metals like lead and tin, then filter the water for reuse—so it’s both effective and eco-friendly. We installed one for a lamp recycler in Regina that processes 500 bulbs an hour. Before, mercury vapor was a constant risk; now, their air tests show mercury levels below Health Canada’s strictest limits. The workers told us, ‘We don’t have to wear respirators all day anymore—we can actually breathe easy.’”

PureFlow’s commitment to affordability doesn’t mean cutting corners. They source 80% of their materials from Canadian suppliers, reducing shipping costs and supporting local economies. Their “Rent-to-Own” program also lets businesses spread payments over time, making compliance accessible. “At the end of the day, clean air shouldn’t be a luxury,” David Liu adds. “It’s a right—and we’re here to make sure every recycler can afford it.”

AirGuard Innovations, out of Ottawa, is Canada’s go-to for high-temperature air pollution control. Founded in 2010, this company has made a name for itself with systems that thrive in extreme heat—think medium frequency electricity furnace equipment and metal melting furnace equipment, where temperatures can exceed 1,500°C. Their secret? Ceramic-based filtration technology that can withstand thermal shock and corrosive gases.

“Traditional filters melt or degrade in high-heat environments,” explains Tom Wilson, AirGuard’s lead engineer. “Our ceramic filters are made from alumina-silica composites, which can handle up to 1,800°C. We recently worked with a foundry in Hamilton that melts scrap metal for automotive parts. Their old system failed every six months, costing $50,000 in repairs and downtime. We installed our ceramic filtration unit, and it’s been running for two years without a hitch. Emissions of iron oxide and carbon monoxide are down by 90%, and they’ve saved over $150,000 in maintenance.”

AirGuard also excels in government contracts, having supplied systems for military bases and public works projects across Canada. Their work with the Canadian Armed Forces on portable metal melting units has earned them a reputation for durability and reliability. “When the military needs a system that can operate in the field, in all weather, they call us,” Wilson says. “That’s the ultimate vote of confidence.”

ClearSkies Engineering, based in Victoria, British Columbia, is all about sustainability—from the systems they build to the way they build them. Founded in 2012, this B-Corp certified company designs air pollution control systems that are not only effective but also made from recycled materials and powered by renewable energy. Their niche? air pollution control system equipment for refrigerator & ac recycling machines equipment and motor recycling machines equipment, where refrigerant gases and oil mist are major concerns.

“Refrigerators and AC units contain hydrofluorocarbons (HFCs), which are potent greenhouse gases,” says Emma Thompson, ClearSkies’ sustainability director. “Our systems capture these gases before they escape, then recycle them for reuse. For a Vancouver-based appliance recycler, we installed a refrigerant extraction and purification unit that recovers 95% of HFCs—turning a waste product into a revenue stream. Plus, the system itself is powered by solar panels on the recycler’s roof, so it’s carbon-neutral.”

ClearSkies also prioritizes circular design. Their systems are modular, so parts can be replaced or upgraded without replacing the entire unit, reducing waste. They even offer a take-back program for old systems, recycling 80% of components. “We’re not just solving today’s pollution problems—we’re preventing tomorrow’s,” Thompson adds. With clients like Environment Canada and major retail chains (who need to recycle old appliances from stores), ClearSkies is proving that sustainability and profitability can go hand in hand.

MetroAir Purification, a Toronto-based company founded in 1998, knows urban air pollution control like no other. Operating in Canada’s most densely populated city, they specialize in systems that minimize noise and space—critical for facilities near residential areas. Their bread and butter? air pollution control system equipment for scrap cable stripper equipment and hydraulic cutter equipment operations, which are often located in industrial zones bordering neighborhoods.

“In Toronto, you might have a cable recycling plant next to a condo building,” says Robert Kim, MetroAir’s sales director. “Noise from fans and bulky equipment can lead to complaints, which is why we developed our ‘QuietFlow’ line. These systems use sound-dampening enclosures and low-noise blowers, keeping decibel levels below 65—quieter than a vacuum cleaner. We installed one for a scrap cable stripper in Etobicoke, and the condo association next door sent us a letter saying, ‘We forgot you were there.’”

MetroAir’s space-saving designs are another win. Their vertical-scrubber systems take up 40% less floor space than traditional models, making them ideal for urban facilities where square footage is expensive. “A circuit board recycler in downtown Toronto had to choose between expanding their operations or installing air pollution control—with our compact system, they did both,” Kim says. With over 200 urban installations across Ontario, MetroAir has become the go-to for companies balancing growth with good neighborly relations.

NorthernClean Systems, based in Edmonton, is Canada’s expert in cold-weather air pollution control. Founded in 2005 to serve Alberta’s oil and gas industry, they’ve since expanded into recycling, with a focus on lead acid battery recycling equipment and metal melting furnace equipment in regions where winter temperatures can plunge to -30°C. Their specialty? Systems that prevent ice buildup and maintain efficiency in extreme cold.

“In Alberta, a frozen filter isn’t just a maintenance issue—it’s a safety risk,” explains Lisa Wong, NorthernClean’s operations manager. “Moisture from emissions can freeze in filters, blocking airflow and causing pressure buildup. Our systems use heated filter housings and insulated ductwork, with sensors that monitor temperature and adjust heat in real time. We installed this for a lead acid battery recycler in Calgary that used to shut down for two weeks every winter due to frozen equipment. Now they run year-round, and their winter maintenance costs dropped by 75%.”

NorthernClean also offers mobile air pollution control units—trailer-mounted systems that can be deployed to remote sites or temporary projects. “We recently sent one to a lithium ore extraction site in northern Manitoba,” Wong says. “They needed a temporary solution while their permanent system was built, and our mobile unit kept emissions in check for six months. It’s like a portable clean-air factory.” With a focus on reliability in harsh conditions, NorthernClean is the backbone of Canada’s northern recycling and mining operations.

Rounding out our list is AtlanticAir Solutions, a Halifax-based company founded in 2010 with a focus on maritime industries. While they serve clients across Canada, their expertise in salt-air resistance makes them a favorite for coastal recycling facilities, particularly those using circuit board recycling equipment and lamp recycling equipment near the ocean. Saltwater corrosion can wreck standard systems, but AtlanticAir’s marine-grade stainless steel and epoxy coatings stand up to the elements.

“A circuit board recycler in Halifax once told us their previous system rusted through in two years,” says Patrick O’Connor, AtlanticAir’s founder. “Salt spray from the harbor was eating away at the metal components. We rebuilt their system with 316-grade stainless steel and added a protective epoxy layer—now it’s going strong after five years, with no signs of corrosion. The cost of upgrading was offset by the savings in replacement parts alone.”

AtlanticAir also specializes in compliance support, helping clients navigate Canada’s strict maritime environmental regulations. “Coastal facilities face extra scrutiny, so we don’t just install systems—we help them document emissions, prepare for audits, and stay ahead of new rules,” O’Connor adds. With clients from St. John’s to Victoria, AtlanticAir is proof that clean air knows no borders—even coastal ones.
