In this video, we go through the different fan speeds on our Corsi–Rosenthal Box so you can hear how noisy this DIY air purifier can get.

As the Corsi–Rosenthal Box is a device you can build yourself, you might find that your CR Box generates more or less noise than ours. But this is a good approximation.

Our CR Box was built on the base of a Hurricane Box Fan (20" Classic Series), so this video shows how a CR Box using that specific fan will sound like when moving through the different fan speeds available.

Our CR Box ranged between 49 – 54 decibels.
