What spot‑exhaust strategies fix negative pressure (range hoods, bath fans, make‑up air) in tight homes?
Big exhaust fans in a small house can cause problems like sucking in bad air. Keep things balanced by using smaller fans or adding air ducts. You can also link fans to bring in fresh, filtered air when exhausting. HRVs/ERVs in boost mode can do this too.
To fix negative pressure issues in tight homes caused by spot-exhaust devices like range hoods and bath fans, consider these strategies
Make-Up Air Solutions
-Make-Up Air (MUA) Systems: Install a dedicated MUA system that provides a controlled amount of outside air to replace the exhausted air.
-Passive Make-Up Air: Use passive vents or grilles that allow outside air to enter the home when exhaust fans are operating.
-Balanced Ventilation: Implement a balanced ventilation system that provides both supply and exhaust air, ensuring a neutral pressure environment.
