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 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 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.
How do I measure humidity correctly?
You can measure the relative humidity in a room using a hygrometer. For measurement to be accurate, it is important for the hygrometer to be positioned correctly: set up the hygrometer on a raised surface in the middle of the room, away from windows and doors. Wait a few minutes for the sensor to adjust to the room temperature.
What is water hardness and how can I test it?
Water hardness is a measure of the quantity of minerals in water. The higher the percentage of those minerals, the harder the water. The device you need will depend on the hardness of your water. If you don’t know the hardness of your mains water, you can ask your local water supplier or contact us to send you a test strip.
How do I determine the size of the room?
It is important to know how big the room in which you are going to be using the device is. If the doors to other rooms are open, the area of those rooms must also be included. Room area is calculated by multiplying the length and width of the room (e.g. 5 x 6 metres = 30 m2). To get the room volume, you multiply the room area by the ceiling height (30 m2 x 2.5 metres = 75 m3).
The room size should be doubled for minimum energy houses with controlled ventilation.
Choose a device that is recommended for at least your desired room size/area.
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.
Where are Stadler Form products manufactured?
Our products are - as usual in the industry - manufactured in China. What is different with us: firstly, all development and design work takes place in our offices in Zug, managed by our founder and CEO Martin Stadler. Secondly, we work closely with our producers in China. This has resulted in partnerships, some of which have existed for over 20 years.a
