After a big storm the air moisture load but if the camera was turned on it continues to add more ..
Good out of it, the operation is tolerable (in my opinion) than low speed.
Then size and aesthetic level it is not terrible for the 2.
Using workplace "polluted" to clear the air is can not be its primary purpose, of course some people think that this can be agreed. For my part I say attention to the filtration: it remains sketchy and does not really purify the air.
While the moist air side will perhaps avoid having too much dust in suspension. but the filter will also be quickly replaced if the unit is operating in dusty environments. These filters are sold at about 10 item, then distrust.
In short, the product is good, but I am not convinced by its usefulness. I'm sure by against those who heat with old electric heaters or wood stoves find this useful device.
