<p>The mounting secures an air filter and water trough to the central portion of a vapourisation-type air humidifier, whose bottom portion forms a water tank, while the central portion is situated between the latter and a cover. Water is delivered by the trough to the filter, which stands upright on the central portion. The filter and trough are secured by a number of bars, each fitting at one end vertically into the central portion, while the trough fits over their other ends. Two of the bars at least have fittings by which the filter is secured.</p> |
