What can I do to improve indoor air quality in my building/space?
Good indoor air quality is achieved through a combination of source identification and control, filtration of contaminants, and dilution of “dirty” indoor air with “clean” air.
Source control
Common sources of poor indoor air quality:
- People
- Cleaning products/practices
Strategies to address poor IAQ at the source:
- Identify contaminants
- Eliminate contaminants
- Mitigate introduction of contaminants
Filtration
Benefits/limitations of filtration
Types of filters
Recommended levels of filtration
- MERV ratings
Common filtration problems
- Dirty filters
- Filters that reduce airflow
Dilution
Natural ventilation
Mechanical ventilation
Unitary air cleaners/purifiers
- Fans
- Air cleaners (HEPA filters, etc.)
- Air sanitizers (ionization, UVGI, oxidization)
