Animal Husbandry & Biosecurity Solutions
Why animal husbandry and biosecurity are hard on air filtration
Dust is how pathogens travel
PRRS, swine influenza and other viruses attach to aerosol particles and move between barns on the air. Filtering the incoming air is the barrier.
Ammonia and hydrogen sulfide are always present
Livestock buildings produce corrosive gases continuously. They affect animal health, staff comfort and the service life of equipment.
Most barns run under negative pressure
Ventilation pulls air in through every available opening. If the inlet is not filtered and sealed, unfiltered air simply finds another path.
The environment destroys ordinary media
High humidity, washing cycles and ammonia attack many filter materials. Media and frames must be chosen for a barn, not for an office.
Recommended filtration system
Biosecurity filtration is normally two stages on the incoming air, with a positive-pressure arrangement for the highest-value barns such as boar studs and SPF herds.
| Stage | Typical class | What it captures | Recommended product |
|---|---|---|---|
| Pre-filtration | G4 / ISO Coarse | Coarse dust, feed, feathers | Pre air filter media |
| Main filtration | H13 HEPA | Pathogen-carrying aerosols ≥0.3 µm | HEPA filter |
| Optional gas stage | Activated carbon | Ammonia, hydrogen sulfide, odour | Activated carbon filter |
Key control points
- 1Filter the incoming air, then control the pressure. Positive pressure inside the barn means air leaves through leaks instead of entering through them.
- 2Two stages, minimum. The pre-filter takes the coarse load so the H13 stage can hold efficiency for a full production cycle.
- 3Seal the building envelope. Filtration is only as good as the weakest gap. Door seals, fan shutters and cable entries all matter.
- 4Choose moisture-tolerant construction. Standard paper separators and untreated frames do not survive wash-down and ammonia.
- 5Change on pressure drop. A wet or overloaded filter reduces airflow, raises ammonia concentration and stresses the animals.
Frequently Asked Questions
Does air filtration really reduce disease in a pig farm?
Yes. Because several major viruses travel on aerosols between barns, filtering incoming air reduces the airborne challenge. It works alongside, not instead of, conventional biosecurity.
What is the difference between negative and positive pressure filtration?
Negative-pressure barns exhaust more air than they supply; filtered inlets still admit unfiltered air through leaks. Positive-pressure barns supply filtered air in excess so the envelope leaks outward — the arrangement used for SPF and boar stud units.
What filter class is used in a livestock barn?
A G4 pre-filter followed by an H13 HEPA stage is the common configuration. The pre-filter protects the HEPA; the H13 stage removes pathogen-carrying aerosols.
How do we handle ammonia and odour?
Ammonia and hydrogen sulfide are gases and pass through particle filters. Control them with ventilation rate, management practice and, where needed, an activated carbon stage.
How often should the filters be changed?
On measured pressure drop rather than a fixed date. In a finishing barn the pre-filter may be changed several times per HEPA cycle; in a breeding unit the interval is usually longer but must be checked.
Key Takeaways — Filter the air coming in, hold the barn under positive pressure, and protect the H13 stage with a proper pre-filter. Dust control becomes disease control.
