How to fix poor air flow in my Lifebreath 200MAX Fan?
- Mmarissa18Aug 8, 2025
To address poor air flow in your Lifebreath Fan, start by cleaning the exterior hoods or vents. Next, remove and clean the filter and core. Ensure grilles are open and unobstructed, and adjust dampers as needed. An electrician should check the supply voltage at the house. Also, verify the duct installation. If issues persist, consider increasing the speed of the HRV/ERV or consulting a contractor to balance the HRV/ERV. Also locate the grilles high on the walls or under the baseboards, install ceiling mounted diffuser or grilles so as not to directly spill the supply air on the occupant (eg. over a sofa). If supply air is ducted into furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably.
