Air Filtration: Enhancing Indoor Air Quality
“Implementing effective air filtration measures is crucial for maintaining clean and healthy indoor environments.” – Anonymous
The air filtration credits of the WELL Building Standard focus on the importance of air filtration in enhancing indoor air quality. By implementing particle filtration strategies, buildings can significantly reduce the presence of airborne contaminants and promote a healthier indoor environment. Let’s explore the requirements and best practices associated with air filtration.
A12.1 Implement Particle Filtration
This credit emphasizes the use of media filters in the ventilation system to filter outdoor air supplied to the space. By implementing appropriate filtration levels, buildings can efficiently capture and remove particulate matter, improving indoor air quality. Compliance with the following requirements is essential:
Filtration Levels Media filters must be utilized in the ventilation system to filter outdoor air based on the annual average outdoor PM2.5 thresholds. The average air filtration efficiency for particles between 0.3 and 1 μm should meet the specified thresholds. The table below outlines the filtration efficiencies based on the PM2.5 thresholds:
| Annual Average Outdoor PM2.5 Threshold | Average Air Filtration Efficiency (particles 0.3-1 μm) |
|---|---|
| 23 μg/m³ or less | ≥ 35% (e.g., MERV 12 or M6) |
| 24-39 μg/m³ | ≥ 75% (e.g., MERV 14 or F8) |
| 40 μg/m³ or greater | ≥ 95% (e.g., MERV 16 or E10) |
These filtration efficiency levels ensure that a significant portion of particulate matter is captured, providing cleaner and healthier air for building occupants.
Filter Maintenance Regular filter maintenance is essential to ensure optimal performance. Evidence of filter replacement according to the manufacturer’s recommendation must be submitted annually through the WELL digital platform. This practice ensures that filters are changed at appropriate intervals, maintaining their effectiveness in capturing airborne particles.
