- Noise Level: I wanted a quiet fan so it wouldn’t disturb the greenhouse environment or nearby spaces. Checking user reviews helped me find quieter options.
- Ease of Installation: A straightforward setup was important. I preferred fans that came with clear mounting instructions and necessary hardware.
