Mechanical Ventilation
Mechanical ventilation refers to the use of mechanical systems to replace or supplement natural ventilation in a building. It intentionally introduces outdoor air while removing indoor air. Systems can be exhaust, supply, balanced, or energy recovery ventilation, and they help maintain indoor air quality, control humidity, and remove contaminants.

Did You Know?
Mechanical ventilation can integrate with HVAC systems to improve energy efficiency and air quality.
FAQ
Is mechanical ventilation only for commercial buildings?
No. Many homes use mechanical ventilation, especially newer, tighter homes that need fresh air.
What is the difference between ERV and HRV systems?
Both recover energy from exhaust air, but ERVs also transfer moisture while HRVs primarily transfer heat.
How often should filters be replaced?
It depends on the system and usage, but most filters should be checked every 1-3 months.
