When a box fan isn't enough
The free Box Fan is a fan on low: soft airflow and a gentle hum. Metal Fan is the other end, a shop-style fan pushing a lot of air, with more presence in the mids and a broader, fuller sound.
It's the one for thin walls, city streets and partners who snore. Keep your volume reasonable; loud sound for hours isn't good for anyone's ears, and the app's loudness matching means it doesn't need to be cranked.
Part of Deeper Nights
