Frequently asked questions

No, a compressor dehumidifier typically draws 200 to 400 W, roughly 0.2 to 0.4 kWh per hour of running. At an example rate of 10¢ per kWh, that's 2¢ to 4¢ an hour; your rate depends on your province and utility, so check your bill. It cycles off once the humidistat reaches its target, usually 50% to 55%. Compare wattage, litres removed per day and whether it has auto shut-off; desiccant models generally use more power.

An indoor relative humidity of 40% to 60% is generally considered comfortable and healthy. Below that, dry air irritates your airways; above it, mould and dust mites thrive. Heated homes often drop below 40% in a cold winter. A hygrometer or smart weather station lets you track each room and trigger a humidifier or dehumidifier automatically.

Yes, a purifier with a true HEPA filter reduces pollen, pet dander and some airborne dust. It does not replace ventilation or cleaning. Check the filter grade (H13 or higher), a clean air delivery rate (CADR) suited to the room, and the running cost of replacement filters.

Pick a purifier whose clean air delivery rate (CADR, in m³/h) matches your room; a common rule of thumb is a CADR of at least two thirds of the floor area in m² for standard ceilings. Aim higher for allergies. Also check the noise level on night mode.

Portable air conditioners cool a room without installation, but they're less efficient than a ductless mini-split, especially single-hose models that exhaust room air outdoors. Compare the cooling capacity and efficiency rating on the spec sheet (European listings show the EU energy class). A dual-hose design, a well-sealed window kit and a timer cut consumption.
