The greenhouse structure uses saltwater to provide evaporative cooling and humidification. Indirect solar desalination by a form of humidification/dehumidification is in use in the seawater greenhouse. This system is often used with air-entrainment nebulizers to provide humidification and oxygen therapy. More specialized retailers might sell&colon; ashtrays, humidification devices, hygrometers, humidors, cigar cutters, and more. Analgesic medications, oxygen, humidification, and ventilator support currently constitute standard therapy. Respiratory gas humidification allows the high flows to be delivered comfortably via the cannula. General measures to relieve symptoms of laryngitis include behaviour modification, hydration and humidification. Benefits include humidification and exponentially improved root exposure to oxygen. The two methods currently available for this purpose are active or passive respiratory gas humidification. The higher the flow, the more important proper humidification and conditioning of the flow becomes. UPW is even sometimes used as a humidification source for the cleanroom environment. Solar humidification takes place in every greenhouse. Condair Group AG is a Swiss manufacturer of commercial and industrial humidification devices and systems. Surgical humidification therapy may also minimise the incidence of adhesion formation. For humidification units, cleaning of the water container is imperative for several reasons.
