You need to reset it, unplug the unit and take out both filters. Then, plug it back and and simultaneously and firmly slam both filters into the back of it at the same time. Before putting both filters back inside the until, also vacuum out the insides in case there is hair/dust inside of it that has accumulated.
Also, make sure your filters are 100% dry before every putting them back inside the unit.
Good luck!

we are also expierencing the same crackling problem. This machine is only a year old.....

anyone find anyway to resolve the crackling? I have not contacted Brookstone, but it doesn't sound too promising anyway.

These air purifiers are not cheap and they should back up their products.
