2016 brings the roomiest humidifier lineup

The former type are designed for easy operation and engineered for outstanding energy savings and quiet operation. The latter models achieve one of the highest levels of energy efficiency among products of their type, and they are also the only humidifiers in the industry equipped with a function enabling sequential operation with an air-conditioner.

Among the five fan-powered steam type humidifiers, the two with a humidifying capacity of 350ml per hour (ml/h) consume a maximum of only 250w and operate at 27dB, making them the most energy-efficient and quietest humidifiers of their type.

They will be available in two colour variations: black and red. Their operating unit display panel has been further improved for easy viewing. The lineup will also include two 600ml/h models, the only humidifiers of this capacity offered by the major Japanese manufacturers, and one 1,200ml/h model.

All models in the fan-powered steam humidifier lineup, including the newly added 1,200ml/h unit, come with a standard-equipped ion filter that curbs scaling, for easy overall maintenance. As with earlier models, they feature ‘double plasma bacterial removal’ functions: one suppresses viruses and airborne bacteria through the release of plasma ions, and the other uses a special filter to capture bacteria and mould. The 350 and 600ml/h models also come with retractable handles convenient for carrying the unit, replenishing or removing water, etc.

All fan-powered steam humidifier models adopt MHI's proprietary system in which vaporisation is achieved simply by heating the water absorbed by the vaporisation cloth, so there is no worry of possible scalding even in the unlikely event the unit were to topple over, as there is no spillage of boiling water. All systems kick in swiftly, requiring only about one minute after operation start.

Also, because with this type of system humidifying capacity is only marginally affected by temperature or humidity, dependable moisturising is provided even in low-temperature ambient environments normally difficult to humidify. Maintenance is simple, and an ‘ECO’ operating mode is provided to reduce the humidifying capacity.

The three hybrid evaporative warm-mist humidifier models offer humidifying capacities of 500, 700 and 850ml/h. They integrate two systems; a vaporising system in which a moist humidifier filter is fanned to induce humidification, and a warm-mist vaporising system in which a moist humidifier filter is placed in a warm air current to induce vaporisation. When humidity is low, humidification is swiftly achieved by warm-mist vaporisation; then, when the pre-set humidity level is reached, the unit switches to vaporisation mode and adjusts the amount of humidification. As changeover between the two modes is automatically carried out depending on the humidity level, unnecessary electricity costs can be significantly curbed. When the unit is set to ‘ECO’ operating mode, the heater is shut off and power consumption is reduced by roughly 90% compared to during normal operation.

All hybrid evaporative warm-mist humidifier models are equipped with a function enabling sequential operation with MHI's SRK-ST series room air-conditioners. Employing a humidity sensor on the air-conditioning unit, signals (ON/OFF) are sent to the humidifier to control the pre-set humidity level. All models of this type also offer superlative ease of maintenance. Their pleated humidifying filter lasts a remarkably long eight seasons (SHK50NR) before replacement is needed, and the standard-equipped silver ion antibacterial agent suppresses water putrefaction and growth of bacteria and mould.
