Atmosphere, purified atmosphere

Difficult to measure the performance of such a device without professional measurement tools. The ionizer used in a room of 40 square meters seems to give some fresh air with a program on one hour of operation.
It can be used against bad smells (kitchen and tested in a room with cat odors but it can also be effective against tobacco odors) or to purify the air of rooms for allergy sufferers.
Operation is simple, programmable with a remote control. The object is easily transported from one room to another. For better distribution, it should place it high on furniture for example. Pretty square and bulky, yet it integrates easily into the background, with a good design.
The noise level is that of an air conditioner or fan midrange. Not really silent but a pattern that can be forgotten.
