The First Prototype
I build the first prototype built and the secret is what's inside. Smells and odours are trapped and stored in side carbon traditionally, we added a secret element to stop the smell seeping out when the device is not being used.
To be effective, a large area and deep bed or carbon is required otherwise air flow is restricted. This was physically large, a flat square shape until we figured out to wrap the flat square filter around into a cylinder shape. One end blocked off, fan sucking through the other end.
As a base, we use the best carbon we can get, Australian RC412 carbon.
The fan and motor assemble we have sourced again is the best quality we could find, German engineering at it finest.
As the Smell Away® SA1 unit is designed for continuous use, power consumption was also a key focus, 14 Watts is the power consumption which is very low.
