How to Improve Air Quality and Ventilation in Veterinary Clinics

Air quality in veterinary clinics is far more complex than in a typical commercial building. Veterinary facilities care for sick, stressed, and often contagious animals, making clean air a critical component of both patient care and staff safety. Poor ventilation can contribute to disease transmission, odor issues, humidity problems, and uncomfortable working conditions.

A Holistic Design Approach to Air Quality

At Design Learned, these challenges are a core consideration in every veterinary facility project. Our animal care experts and building engineers approach air quality not as a standalone system, but as a critical component of the overall facility design. Improving air quality requires a holistic design approach. No single system or product can solve indoor air quality concerns on its own. The veterinary facilities our team of designers supports combine ventilation strategies, air movement, humidity control, filtration, and surface sanitation into one coordinated system.

Start with Fresh Air Dilution

Fresh outside air is one of the most important tools for improving indoor air quality. Bringing outside air into the building helps dilute airborne contaminants, odors, and pathogens. However, using 100% outside air is not always financially feasible. We also know that conditioning large amounts of outdoor air can significantly increase operational costs, particularly in climates with extreme temperatures or humidity. Our building care experts work to balance healthy air exchange with long-term energy efficiency.

Focus on Air Distribution

How air moves through a veterinary clinic matters as much as the amount of air supplied. In animal housing areas, strategic air distribution helps prevent contaminants from spreading throughout the room.

One highly effective approach is to use linear diffusers at the fronts of kennels or cages. These diffusers create a “curtain” of air that moves downward and pushes airflow from the front of the enclosure toward the back, where exhaust air is removed. This directional airflow helps contain odors, dander, and airborne pathogens while improving overall cleanliness within the space.

The team at Design Learned incorporates these types of airflow strategies early in the design phase, coordinating with enclosure layouts and facility workflows to ensure air movement supports (not works against) daily operations.

Place Exhaust Systems Strategically

Exhaust systems should be carefully designed to remove the dirtiest air from the most critical locations. Exhaust grilles that are poorly located may leave contaminants trapped within the space or fail to perform effectively.

Strategic exhaust placement allows the ventilation system to capture airborne pollutants efficiently before they spread to adjacent rooms or public areas. This is especially important in isolation rooms, treatment areas, and animal housing spaces where contaminants are more concentrated. Through our integrated design approach, our team ensures that exhaust placement aligns with both clinical risk zones and real-world staff movement, helping facilities maintain cleaner air where it matters most.

Create Logical Mechanical Zones

Mechanical zoning is another essential part of maintaining good air quality. Veterinary clinics should not operate as one large, shared air system. Instead, HVAC zones should be small and logically separated based on room function and species type. For example, dog housing, cat housing, surgery, isolation, and public areas should each have independent or carefully controlled zones.

Proper zoning reduces cross-contamination risks and allows each area to maintain ventilation rates appropriate for its specific use. The Design Learned team of designers and mechanical engineers creates zoning strategies that reflect how the clinic actually operates - supporting both infection control and staff efficiency.

Invest in Advanced Air Filtration

Air filtration technologies continue to evolve and can play a major role in animal health. One increasingly common strategy is ultraviolet germicidal irradiation (UVGI), which helps neutralize airborne pathogens within the HVAC system. Advanced filtration systems can significantly reduce bacteria, viruses, and other contaminants circulating through the building. When combined with proper ventilation and airflow design, these technologies help create a healthier environment for animals, staff, and visitors.

Design Learned helps clients evaluate these systems within the broader context of their facility goals, ensuring that technology investments align with both clinical needs and long-term maintainability.

Don’t Overlook Dehumidification

Humidity control is often the most overlooked aspect of indoor air quality in veterinary facilities. Fresh outdoor air introduces moisture into the building, and veterinary clinics also generate significant humidity through cleaning, washing, and animal care activities. Excess humidity contributes to odor problems, microbial growth, and disease transmission. Effective dehumidification is essential to maintaining a clean, comfortable, and healthy environment.

The design team at Design Learned prioritizes moisture control as part of its integrated design approach, recognizing that ventilation strategies must work hand in hand with humidity management to improve air quality truly.

Support Air Quality with Surface Cleaning

Air quality extends beyond the air itself. Advanced surface cleaning technologies and sanitation protocols also help reduce airborne pathogens. Clean surfaces minimize contaminants that can be reintroduced into the air through daily activities and movement within the clinic.

We reinforce this connection by designing spaces that support effective cleaning protocols - selecting materials, layouts, and finishes that make sanitation easier and more consistent.

Creating Healthier Spaces

When ventilation, humidity control, filtration, and cleaning strategies work together, veterinary clinics can create healthier spaces that support animal recovery, staff wellness, and long-term operational success.
