WHAT IS RELATIVE HUMIDITY?
Humidity is the proportion of water vapour in the air. The relative humidity provides information on the saturation of the air with water vapour in the form of a percentage – always as a function of the temperature. That means: if the relative humidity is 100%, the air is completely saturated and if it is 50%, it is half-saturated with water vapour. You can measure the relative humidity using a hygrometer.
WHAT IS AN OPTIMAL INDOOR CLIMATE FOR YOUR HOME?
An optimal climate for the home and office is a room temperature of 20-23 °C and a relative humidity of 40-60% as recommended by doctors and medical experts. In the bedroom in particular, these values can noticeably improve your nightly rest.
WHAT DO POLLUTED INDOOR AIR AND POOR AIR QUALITY ACTUALLY MEAN?
According to the World Health Organization (WHO), the air indoors is 2 to 5 times more polluted than the air outdoors. The level of pollution has a direct effect on air quality: the higher the level, the poorer the quality. Pollutants such as fine dust, animal hair, pollen, viruses, bacteria, mould spores and smoke can contaminate the air.
CAN A HUMIDIFIER OR AIR PURIFIER PROTECT AGAINST CORONAVIRUS?
Both devices can help but won’t provide 100% protection against the virus. The humidifier creates an optimal indoor climate in which viruses find it much harder to survive.
Air purifiers can remove some viruses from the air using a HEPA or electrostatic filter. However a conventional domestic air purifier won’t be able to completely eliminate all viruses from a room. In addition, viruses can survive in a filter for a long period of time. That is why it is very important for filters to be replaced and cleaned regularly.
WHAT IS THE DIFFERENCE BETWEEN HUMIDIFIERS, AIR WASHERS AND AIR PURIFIERS?
A humidifier ensures optimal humidity in the air by adding water to it, i.e. humidifying the air. There are various systems: evaporators, vaporisers and ultrasonic nebulisers.
An air purifier reduces the air pollution indoors. Particles such as fine dust, pollen and viruses as well as unpleasant odours will be removed from the air. There are various systems for these too (HEPA filters or devices with an electrostatic filter). The air purifier does not affect the humidity in the air.
The air washer is a 2-in-1 device that washes pollutants from the air and humidifies the air at the same time when it is too dry.
