TAAV Vaporaire Steam Vaporiser increases moisture in the air to soothe nasal and respiratory passages promoting better sleep. Assists with the relief of croup, head colds, sinusitis and bronchitis. Our bodies are up to 60% water and the respiratory system needs moisture to operate effectively - if not, it cannot do its job of trapping cold and flu viruses and keeping the airways clear. Warm steam from a TAAV Vaporiser helps loosens phlegm, helps clear congestion from the chest and nasal passages and allows easier breathing.
