Which humidifier do I need?

If you want to find out if you need a humidifier
Buy a thermohygrometer. The ideal humidity for most normal situations is between 40-60% relative humidity. If the thermohygrometer reads below this you probably need a humidifier. If it reads above this you may need a dehumidifier.

If you need to humidify a single room
Select the Room humidifier for areas up to 85m2 or the Air Washer, Boneco 2055D for areas up to 50m2.

If you need to humidify a large area like a whole floor of a house
Select the Home humidifier for areas up to 110m2.

If you need to humidify an office or large commercial area
Select the AxAir LBV45 humidifier for larger areas up to 900m3. If you need a more permanent solution to your dry air problems then we also supply a range of industrial wall-mounted humidifiers for use directly in a room or in air handling units and ducts. However, these need expert installation and mostly require 3-phase power supply.

If you need to humidify an industrial area
Select the Mistifier for areas up to 2,000m3. This type of cool mist humidifier will produce small amounts of moisture on the floor near to the unit. For this reason it isn’t suitable for office type environments but is ideal for printers, textile manufacturers or for use in greenhouses. If you need a more permanent solution to your dry air problems select from our range of industrial wall-mounted humidifiers for use directly in a room or in air handling units and ducts.

If you need a very quiet system for use in a bedroom
Select the Air Washer or the Boneco 2055. All these systems run at under 25dB(a).

If you want something that has very low running costs
Select an evaporative humidifier like the Room humidifier, Home humidifier, AOS Combi, Air Washer or Boneco 2055. Other systems that heat the water to produce steam or warm mist will require higher levels of power.

If you want to avoid buying ongoing spare parts like filters or evaporative cartridges
Select the Air Washer or Boneco 2055 as they do not require any consumable parts. Please note all humidifiers still need to be cleaned and maintained.

If you want to relieve symptoms of Croup or other respiratory illnesses
Select a steam humidifier like the Boneco AOSS150 steam humidifier.

If you would like to purify the air as well as humidify
Select the Combi as it incorporates two HEPA filters and a carbon filter. Alternatively the Air washer and Boneco 2055 will also purify the air through washing it during the humidification process. You will see just how effective this is when you empty the unit – the dirt from the atmosphere will be in the unit’s water tank. By humidifying an atmosphere you will also suppress dust, further improving your environment.

If you want a unit that will automatically control the output and maintain a set humidity
Select either the Boneco 2055D humidifier or the Home Humidifier for small domestic areas as they incorporate internal humidistats and allow you to program in your desired humidity. For larger commercial areas the Defensor PH15 humidifier comes with built in digital humidistat. Alternatively select any of our humidifiers and use it with a plug-in humidistat, which will turn off the power to the unit when a set humidity is reached and reactivate it when the humidity drops. This is especially recommended for use with our steam humidifiers to avoid over humidification.
