AIR PURIFIERS
Nowadays, we spend up to 90% of our time indoors. According to the World Health Organization (WHO), the air inside is 2–5 times more polluted than outside. This means that even in enclosed spaces, air pollution can be a massive burden on the body. Symptoms of hay fever, dust allergy or dust mite allergy can be treated with medication or also alleviated through the use of alternative solutions such as air purifiers.
Good quality air for allergy sufferers
People with allergies suffer from poor air quality in particular. But so do children, pregnant women, the elderly, people with heart disease and people with existing respiratory disorders. Typical symptoms include: fatigue, an itchy blocked nose, the urge to sneeze, watery eyes, a scratchy and swollen throat, coughing and wheezing, tightness in the chest, hives, rashes and asthma attacks.
Physical reactions are often caused by breathing in pollen, dust, animal hair, dust mites or other contaminants in the air. These can be treated with medication and there is a wide range available for combating symptoms: from nasal sprays and eye drops to antihistamines or asthma sprays.
However, medication often also has side effects and that is why it is recommended – according to the severity of the allergy – to use home remedies and indoor alternatives such as air purifiers to alleviate the problem.
Better quality of life
Besides medication, there are also home remedies such as spicy ginger water, vitamin C, salt water nasal sprays, etc. as well as homeopathic remedies. For indoors, there is another recommended and highly effective solution: air purifiers. Air purifiers are devices which draw in the contaminated air and have a filter system which filters particles, pollen, allergens, bad smells and volatile organic compounds from the air. The purified air is emitted back into the room. With a Stadler Form air purifier, you can see a lasting improvement in your quality of life and finally start to breathe easy again.
Advantages of optimally purified air
- Better well-being – Pollutants are removed from the air and the burden on the human body is reduced – greater well-being in everyday life.
- Fewer allergic reactions – Allergic reactions are reduced or avoided completely – asthma or allergy sufferers can breathe easily.
- Fresh indoor air – The air indoors seems fresher and cleaner and is more pleasant to breathe – fresh air for a healthy life.
- Active and efficient – Signs of tiredness and lack of concentration are reduced – greater efficiency when working and pursuing hobbies.
- Get rid of bad smells – Bad smells from cooking and other sources are quickly removed effectively.
- Breathe freely – Symptoms of respiratory diseases are reduced.
Additional protection against viruses
The coronavirus pandemic proves again, that the quality of the air is very important for our health. Viruses such as the coronavirus SARS-CoV-2 attach to particles and remain airborne for quite some time. An air purifier can help to filter those virus particle packs from the air and thus reduce the viral load. It is very important to change the air purifier filter regularly to allow best filtration performance possible. However, an air purifier doesn't provide a 100% protection against viruses. Common rules such as washing hands regularly or social distancing remain mandatory and wearing a mask can make sense, too.
More about air purifiers and the coronavirus
So-called MS2 virus tests are carried out because these viruses are deemed representative of SARS-CoV-2. Measuring 25 nanometers, MS2 viruses are no less than 4 times smaller than SARS-CoV-2 which causes COVID-19. Stadler Form arranged for the whole family of Roger air purifiers to be tested in an independent laboratory by Airmid in the UK based on this procedure. Those tests confirmed that Roger and Roger little were able to remove 99.3% and Roger big 99.9% of the viruses from the air within an hour. It can be concluded from the results that the larger SARS-CoV-2 viruses would also be reduced at least to the same extent. So when used and maintained correctly, air purifiers can reduce the risk of you becoming infected with the coronavirus.
What is filtered out of the air?
4 tips for purchasing an air purifier
1. Know your room size
Not every device is suitable for any room size and that is why it is important to know the size of the room in which your air purifier is going to be used. The bigger the room, the more powerful your device will need to be. One way of telling how powerful a device is is by looking at the Clean Air Delivery Rate (CADR) value: this indicates the volume of pure air produced. So the bigger the room, the higher the CADR value will need to be. A lot of manufacturers also indicate the appropriate m2 number.
2. Choose your preferred technology
There are two different types of technology to choose from: HEPA filters and electrostatic filters. While both filter particles, viruses, pollen and a lot more besides from the air, the difference between them lies in the way they are maintained. The HEPA filter needs to be replaced regularly which can be done quickly and easily and with very little effort. The electrostatic filter itself can be cleaned, a task that will need to be done regularly. So it produces less waste but does involve a certain amount of effort.
3. Do I need an activated carbon filter?
Only activated carbon filters can remove unpleasant odours and gases from the air. An air purifier WITHOUT an activated carbon filter cannot remove unpleasant odours and gases from the air reliably and effectively. The more activated carbon there is in the filter, the more efficiently it will be able to remove unpleasant odours and gases from the air. The heavier the activated carbon filter, the more activated carbon it contains and the more gases and unpleasant odours it can adsorb.
4. Look at the noise level
Another important indicator is the noise level. No-one likes a noisy device and particularly if your air purifier is going to be used in a living room or bedroom, it is worth looking at the number of decibels it will produce. The important thing is for the device to operate quietly on a low setting. Air purifiers should be left on all the time as that is the only way that they can purify the air effectively. Therefore it is most important for them to operate quietly on a low setting so that they will not disturb you or stop you from getting a good night’s sleep.
Our devices ensure healthy air quality by reducing particles, viruses, bacteria, bad smells and other air pollution.

CADR stands for "Clean Air Delivery Rate", which helps when comparing air purifiers. The CADR is measured by a laboratory. The recommended room size for an air purifier can be derived from the CADR.
The more frequently the air in a room is circulated per hour, the cleaner the air becomes. For normal air pollution levels, it is enough for the air in a room to circulate three times (the room's entire air volume must circulate through the air purifier three times). For allergy sufferers, we recommend that the air volume circulated five times. The higher the speed setting the air purifier is set to, the more air is circulated per hour. Generally, we recommend running the air purifier continuously instead of just intermittently so that the air in the room is constantly being circulated and cleaned.
Stadler Form offers two different systems, which are partly comparable in their functions. Air washers are primarily used to increase the air humidity in a room (functioning as an air humidifier). Additionally, thanks to their technology, they can filter particles from the air with the help of the disc package (functioning as an air purifier). Thus, air washers offer two functions in one unit. Air purifiers, on the other hand, cannot humidify the air. Thanks to specifically designed filter technology, air purifiers can filter particles and gases from the air with much higher efficiency than air washers. Furthermore, air purifiers have filters which filter much smaller particles (respirable particles) from the air, and their cleaning volume is greater than an air washer's as a rule. Depending on the application, it makes sense to choose one device or the other. We will be happy to advise which device best suits your needs.
Passive/Minergie houses have a built-in ventilation system that circulates a room's entire volume of air several times per hour. The room in the air is drawn out and replaced with fresh air from outside. During this process, the heat of the room is recovered via a heat exchanger and so the potentially cooler air from outside is heated again. These systems do not always have adequate air-purification facilities, meaning air pollution in passive or Minergie houses is also a pressing issue. When using an air purifier in this setting, we recommend reducing the performance of the ventilation system to a minimum. This gives the air purifier the chance to clean the air effectively. To change the settings of your ventilation system, contact the manufacturer or your landlord. If you have any further questions, please do not hesitate to contact us.
