EPI Air is on the cover of National Hog Farmer!

EPI Air is on the cover of the November issue of National Hog Farmer!  New research by Dr. Gil Patterson (Swine Vet Clinic) and U of M Researchers points to EPI Air having an impact on reducing PRRS.  Read all about it.


It just makes sense…clean air is better!

EPI Air and PRRS

Here is what Dr. Gil Patterson of Swine Vet Center has to say about EPI Air and PRRS.  Dr. Patterson has conducted research evaluating EPI Air’s effect on the PRRS virus:


“The PRRS virus is one of the most challenging diseases that affect swine.  It is especially difficult to contain and control because of its ability to travel through the air. Recent research has demonstrated that EPI air helps reduce the quantity of aerosolized PRRS virus both within and outside of commercial swine barns. This helps to improve the health and performance of PRRS-challenged pigs, and reduces the threat of transmission to neighboring herds.”

Air Filtration System adding $3.16 per pig

FeedstuffsFeedstuffs, March 25, 2013

By Krissa Williams, Industry Insider

By Murphy-Brown LLC, North America’s largest hog producer, has generated an additional $1.896 million in five months at its commercial nurseries in Milford, Utah, thanks to a new air filtration system. Based on 194,000 nursery spaces, an enhanced environment created by EPI (electrostatic particle ionization) Air is adding $3.16 per pig placed (Table), according to the company. EPI Air is the patented product of Baumgartner Environics Inc. (BEI) of Olivia, Minn. The technology generates electrically charged ions that clear the air of dust and other harmful emissions such as ammonia and hydrogen sulfide. In February, Murphy-Brown released system-wide pig performance data comparing pre-EPI versus post-EPI technology and involved 600,000 nursery pigs. With a fi ve-week nursery period, the net value per turnover feed cost was $5.318 million for the pre-EPI environment and $5.932 million for the post-EPI regime. Bob Coffelt, business development director at Murphy-Brown, said the company is pleased with the results and noted that they were better than projected from initial trial runs. He also believes the company will be installing the technology into all of its grower/fi nishing facilities as well. Murphy-Brown markets 17 million pigs annually. “We’re tremendously excited about these results and thankful that Murphy-Brown continues to be visionary in this entire cleaner air issue,” said Matthew Baumgartner, general manager and head of development of the EPI technology for BEI. “They recognize the ongoing value of EPI Air and are now reaping significant economic benefi ts of the technology.” Next on the horizon is an improved version of the original EPI technology that positions the corona points (discharge points) 50 in. above the fl oor level and concentrates cleaner air in the “pig breathing zone.” The new generation also reduces dust accumulation on the ceiling and lowers capital costs. “This will likely increase the overall efficiency because you are placing this blanket of ions closer to the pigs. Plus, inside walls and ceilings may stay cleaner because the dust collection process will be at a lower level. Making ‘nuisance dust’ less prevalent is a good thing for employees,” Coffelt said.

The original system provides ionization for about 6,000 sq. ft. per unit; the new generation system will handle 15,000 sq. ft. of fl oor space per unit. Baumgartner said his firm will be marketing turnkey packages, meaning his recommended crew will be doing the installation. For a 60 ft. x 100 ft. nursery structure, the installation time would be about eight hours. Operating costs are comparable to the cost of running a 100-watt bulb for 24 hours, he said. The air system has proven to improve the environment and increase profits, but it may also reduce the threat of porcine reproductive and respiratory syndrome (PRRS), which continues to be the most costly disease plaguing the swine industry. Current estimates indicate that PRRS costs swine producers $650 million per year. “It continues to be the disease that shakes the industry,” according to Coffelt.

Is it possible that cleaner air may lessen the PRRS threat? While Coffelt’s theory has not been confirmed, Dr. Montserrat Torremorell, Leman chair in swine health and productivity at the University of Minnesota, is currently researching this very issue for EPI Air and non-EPI Air environments. Additional PRRS research using EPI Air is also being conducted by Dr. Qiang Zhang at the University of Manitoba. “It will be most interesting to see if these tests do reduce the overall level of PRRS virus density. Logic suggests that as you move the dust particles out of the air, you are removing bacteria also, so perhaps this might be a positive result, but I certainly wouldn’t make that claim at this time,” Coffelt said.

New technology could improve confinement livestock efficiency

It’s called electrostatic particle ionization and an Olivia, Minn., company says the technology can help confinement livestock producers be more efficient.

As published in AgWeek. Monday, March 18, 2018

It’s called electrostatic particle ionization and an Olivia, Minn., company says the technology can help confinement livestock producers be more efficient.

Put simply, EPI “scrubs the air” to create healthier air for pigs to breathe, says John Baumgartner, president of Baumgartner Environics.

His company manufactures and sells EPI Air, a patented dust reduction system that generates electrically charged ions, which clear the air of dust and other harmful emissions such as ammonia and hydrogen sulfide.

The system recently received high marks from Murphy-Brown LLC, the world’s largest pork producer. Murphy-Brown used the technology at its commercial nurseries in Milford, Utah. The project, which involved 600,000 pigs in what EPI Air calls a “system-wide commercial performance,” not merely a test, found that the system reduced swine mortality and increased daily weight gains at the Utah plants.

“Yes, we are indeed pleased; 600,000 pigs don’t lie,” Bob Coffelt, Murphy-Brown’s business development directors, says in a news release.

His company plans to install the technology in all its grower and finishing facilities, Coffelt says in the release.

David Newman, North Dakota State University Extension Service swine specialist, says he’s heard of the EPI technology and the Murphy-Brown tests, but isn’t familiar with the details.

Nonetheless, the basic concept appears sound, he says.

“It’s about reducing dust and improving air quality. We know that if you can improve air quality, you’ll improve efficiency in your pigs. That’s been scientifically proven,” Newman says.

USDA roots

The Olivia company’s product builds on research conducted by the U.S. Department of Agriculture’s Agricultural Research Service in Athens, Ga., Baumgartner says.

Baumgartner Environics licensed an ARS patent for the technology to use in agriculture. The company further developed the technology, making improvements and taking costs out of the system.

The Olivia company has submitted several patents of its own to reflect improvements it’s made, he says.

EPI Air is a modular system. One power supply for the system can treat about 15,000 square feet, at a cost approaching $1.70 per square foot, Baumgartner says.

The system installed at the Murphy-Brown facilities in Utah paid for itself in just 75 days, according to Baumgartner Environics.

The cost of operating the system is roughly the same as the cost of running a 100-watt light bulb, Baumgartner says.

No special outlet or wiring is needed, he says.

‘Healthy skepticism’

Baumgartner started Baumgartner Environics in 1989 as an environmental consulting company.

Later, it became an environmental products company, focusing on providing systems to agriculture that address environmental issues and contribute to profitability.

Baumgartner Environics’ next product is EPA Air II. Billed as an improved version of the original technology, it will be released in April. The next version will, among other things, concentrate on providing cleaner air in the “pig breathing zone,” according to the company.

Some people have what Baumgartner calls “general healthy skepticism” to the product.

“The commercial data is so good that most people find it hard to believe.  That causes skepticism. You can’t see these ions. It’s like ‘How can this possibly work? It doesn’t cost much to operate. How can this work?’” he says.

In time though, “It’s going to become understood that this is a technology everyone producing confinement livestock in the future will adopt in their operation,” Baumgartner says.

“I think it’s game-changing technology,” he says.

The Value of Clean Air – $3.16 per Pig

The world’s largest hog producer, Murphy-Brown LLC, recently installed EPI Air in its Circle Four commercial nurseries in Milford, Utah. After only 5 months, 600,000 nursery pigs treated with EPI Air generated an additional $1,896,000 in profit. Based on 194,000 nursery spaces, the enhanced clean air environment created by EPI Air added $3.16 per pig placed.
