Get rid of smells in small/medium spaces 👌
With its unique stackable design you can add or remove layers depending of the smell intensity.
Growing plants tend to smell less than during the end of flowering.
You can change and refill with carbon pellets when needed.
Just cut the zipties, unstack layers, and change them for some fresh activated carbon pellets (easily findable in most petstores as they're used for aquariums).
