Reed sticks aka diffuser reeds are simply the conduits or carrier channels for your reed diffuser oil.
Think of a straw divided into a couple of dozen fibrous tubes.
Each 2.75 mm or 3 mm reed stick contains 20 or more individual cellular sections that run from top to bottom of the reed-like 20 micro-mini straws (cells, channels, microscopic tubes- whatever you want to call them).
The reed sticks’ cells are totally open to pull liquid from bottom to top. This wicks the fragrance from inside the bottle is an example of capillary action, carrying it to the top surface of the reed, and releasing the fragrance into the air naturally.
With their vibrant scents, reed diffusers are the best alternative to candles. There's no risk of fire. Reed diffusers have a wonderful aromatic scent while being flame-free and absolutely no heat is needed. This makes them safe for classrooms, offices, nursing homes, homes. Do keep them out of reach of young children and pets.
Remember to turn your reed sticks over when the scent stops diffusing. When they finally do not respond to turning, it’s time to replace them with fresh reeds. They’re inexpensive and a tube of 100 goes a long way.
