Calmly’s breathing devices are made using additive manufacturing technology, with specialised coatings. We are designing our devices to last, so the only thing you’ll need to replace regularly is the aroma round (once the aroma has been expended). Our Company is deliberately avoiding the use of disposal/one time use devices, to minimise our impact on the environment.
The aroma rounds (being made of terra cotta clay) can be disposed of without guilt, given they are simply baked earth. Please be mindful where you leave the rounds, especially when young children are present, to avoid a potential choking hazard.
