Filters do not last as long as advertised. Contacted Eco Four Twenty, still waiting on a reply.

If you have two filters, we recommend rotating the filters every week to extend the life of the filters.

I found the whole filter would leak when you exhaled into it
Aluminum Sound (store manager) –
Very weird, might be the filter stop by and ask for Dade, ill hook you up with a new one

Very discreet. It’s almost the size of a pencil sharper and it looks like one. No smell, no smoke. It does leak a little bit of smoke but not enough to stink up a room. That could also be from me not pushing my mouth on it hard enough.
