The Compact Kit is able to neutralize a space of 20m3, or 710ft3*. The oils also last between 4- 6 weeks with 24/7 use. 1 hour activation as standard. Comes with a zip tie so you can attach this to your grow tent easily.
The Neutralizer works in a specified amount of space, and the number of units required will be determined by the density of smell or smell sources in the room.
Like with an AC unit, and as an example, an office of 4 people may require 3000BTU output to cool it. However, an output of 3000BTU would not be sufficient if there were 25 people in that room.
The Neutralizer functions in the same way. So if you happen to notice unwanted smells in the correct sized space, it may be the odour density is too strong for 1 unit; add an extra Neutralizer to your space.
