WetAir knowledge base
Practical climate guides for your home
Start with the room and the problem you want to solve. These guides explain the trade-offs, safety limits and equipment details to check before choosing or using a product.
Humidity and clean air
Measure first, then decide whether to add moisture, remove it or clean the air.
- How to find the cause of excess indoor humidity Match measurements to where and when moisture appears, correct the source, then decide how the remaining airborne moisture should be controlled.
- How to match a dehumidifier to the load and routine Room volume sets the scale, but temperature, moisture source, air exchange and the way the appliance will be used change the capacity needed. A practical choice must also account for water removal, maintenance, placement and noise.
- How to care for a humidifier Fresh water, regular cleaning and complete drying help keep the appliance suitable for everyday use.
- How to choose a humidifier for a room WetAir humidifiers are ultrasonic; the models differ in tank size, coverage, controls and extra features.
- How to choose an air purifier for your home Room size, filter composition and regular filter replacement decide the result more than the number of buttons.
Heating and hot water
Estimate heat loss, compare heater formats, work out running costs and size a water heater.
- How to choose a heater for the cold season Choose from the room's heat loss and intended routine, then check the format, controls and safe placement.
- How to match heater output to room size Area gives a first estimate; ceiling height and heat loss decide whether that estimate is realistic.
- Convector or oil-filled radiator: which to choose A convector usually responds more quickly; an oil-filled radiator takes longer to warm up and cool down. Both heat the surrounding air by natural convection.
- How much an electric convector costs to run The bill depends on the heater's power, the time its element actually heats and your electricity tariff.
- How to choose a storage water heater for a flat Tank volume decides how many people can shower in a row; power decides how quickly the water reheats.
Cooling and air movement
Separate true cooling from air circulation and plan the setup before hot weather.
- How to cool a room in summer Reduce heat gain first, then choose true cooling or air movement according to the result you need.
- How to install a portable air conditioner Correct routing of the supplied exhaust hose, an adequately sealed window gap and clear airflow are central to portable cooling.
- How to organise air movement in a room Use fan position and airflow direction to improve comfort without confusing circulation with refrigeration.
Food preparation
Plan drying from product-specific preparation and safety through doneness checks and storage.
- How to dry vegetables, fruit, herbs and meat at home Reliable drying starts with uniform preparation, clear airflow, a product-specific doneness check and a separate safety plan for foods of animal origin — not with a promise from the timer.
- Dehydrator temperatures and drying times Food safety sets the temperature; slice thickness, humidity and tray loading set the time.
