Restore your sense of calm, relaxation and overall well-being with Zadro’s Aromatherapy Personal Oxygen Bar. It’s quiet, compact, portable, and modeled after oxygen bars found in luxury resorts and spas that help increase self-care and overall well-being. Zadro’s oxygen bar produces oxygen-enriched air through a quadruple air filtration system and French-imported molecular membrane that increases oxygen concentration up to 90% (compared to 21% oxygen concentration of normal air*). Adjustable oxygen concentration from 30% oxygen up to 90% oxygen lets you control your relaxation experience. Choose to add essential oils to the oxygen for instant spa-like aromatherapy at home (lavender essential oil included)**.
