Taking a deep breath and enjoying the fresh air should be possible in every home – and not just in the Swiss mountains. Air purifiers keep the air free from particles, pollen, allergens, bad smells and volatile organic compounds (VOCs).
Allergy sufferers know the restrictions on their everyday life when the air isn't as clean as it should be. With a Stadler Form air purifier, you can see a lasting improvement in your quality of life and start to breathe easy again.
There are various systems with the same aim: removing particles from the air. HEPA filters or electrostatic filters can be used for this; carbon filters are effective in dealing with odours. Air purifiers can be effective in bedrooms, kitchens, living rooms and offices.
Alternatively, an air washer can keep the air clean and humidify it at the same time.

We spend up to 90% of our time indoors. According to the World Health Organization (WHO), the air inside is two to five times more polluted than outside. It reports that, in 2014, approximately 92% of the world's population lived in places where the WHO's pollution level targets were not met.
We inhale 12,000 liters of air every day, that's approximately 15 kg – far more than our intake of food or water. The air we breathe directly influences our wellbeing and health.
Unfortunately, more and more people are suffering from allergies and heart and respiratory diseases caused by air pollution. Today, 20% of the world's population already suffers from allergic diseases, and the trend is growing. Smog alerts (summer and winter smog) are being reported in an increasing number of cities, and the legal limits of particulate pollution are increasingly exceeded.
There are various impurities in the air indoors, which basically fall into one of two categories: particulate and gaseous pollution. Below is a list of possible indoor air impurities:
- Bad odors (cooking, wet clothes and shoes, pets, etc.)
- Volatile organic compounds (VOCs)
- House dust mites and their feces
- Smoke and tobacco
- Bacteria and viruses
- Pet hair
- Mold (mold spores)
What are the causes of the different factors of air pollution? It is very important to know the possible sources in order to avoid them as much as possible and to reduce the related pollution. Pollution sources:
- Cleaning supplies (floor cleaners, household cleaners of all kinds)
- Furniture and household textiles
- Air freshener sprays
- Adhesives and paints
- Paint strippers
- Body care products
- Printed materials
- Electronic devices
- Candles and incense sticks
- Combustion of fuels for cooking and heating
- Furniture and building materials
- High humidity and lack of ventilation
There are various medical conditions that occur as a result of poor air quality and indoor air pollution. Typical medical conditions are: asthma, irritation of the throat, nose, and eyes, chronic and acute respiratory diseases, lung cancer, heart disease, and reduced fertility.
The following groups are particularly susceptible to air pollution: children, pregnant women, seniors, people with heart disease, and people with existing respiratory problems. Various factors can also further increase the risk of disease: genetic predisposition, an erratic lifestyle, and unhealthy eating habits.
People with allergies suffer from poor air quality in particular. Typical allergy symptoms are: an itchy and congested nose, urge to sneeze, watery eyes, scratchy and swollen throat, coughing and wheezing, tightness in the chest, hives, rashes, and asthma attacks. An air purifier can help allergy sufferers to breathe easily and sleep deeply and restfully, free from symptoms. Allergies can occur for a variety of reasons. Typical allergies (related to air quality) are explained in detail below.
An allergy to pollen is often inherited and is a reaction to one or several types of pollen. The immune system reacts to the proteins in the pollen. Upon inhaling or coming into contact with pollen, the body releases histamine, resulting in an inflammation of the conjunctiva of the eyes or nasal mucous membrane. If a pollen allergy is left untreated for a long time, it may develop into allergic asthma. A physician can make a diagnosis with skin and blood tests. There are various medications to treat the symptoms as well as special desensitization therapies. An air purifier helps to quickly reduce the levels of allergens in indoor air, allowing you to breathe more easily.
House dust mites live in every home and belong to the arachnid class. There are 150 different known species of this type of mite, and the creatures are invisible to the human eye. One mite produces up to 40 fecal pellets per day, which contain allergy-inducing components, and which lead to allergic reactions when inhaled. Regular cleaning of mattresses, pillows, and sheets helps to combat this. There are also mite-proof covers that can limit the problem. Additionally, dust in the house should be reduced as much as possible. If necessary, medications help to deal with the symptoms. Of course, a regularly maintained air purifier also helps to sustainably improve the air quality.
Asthma is not an allergy, but allergens are the most common trigger of bronchial asthma. And not every airway constriction is asthma. A diagnosis must be made by a specialist, i.e. a pulmonologist or allergist. Avoiding contact with allergens can, of course, provide relief. In addition, a drug therapy can be discussed with a doctor. In the case of asthmatic conditions, an air purifier helps to reduce the level of allergens in the air and so alleviate the symptoms. An air purifier cannot, of course, replace a specialist, which is why we recommend an air purifier as a supplement to medical treatment.
Volatile organic compounds (VOCs)
Volatile organic compounds (VOCs) are organic substances that occur in gaseous form in the air. Typical sources of VOCs indoors are bacteria and molds, plastics, building materials, furniture and carpets, as well as cleaning products, and the waste products of smoking. VOCs can trigger a range of symptoms in humans such as headaches, tiredness, sleep disorders, irritation of the respiratory tract, and hypersensitivity reactions. Their symptoms are also summarized under the term "sick building syndrome". Air purifiers like Roger and Roger little can filter these VOCs out of the air. However, the activated carbon filter must be regularly changed as it will eventually become saturated with pollutants. Alongside the use of an air purifier, it is recommended that you determine and eradicate the source of the pollutant.
Particulates come in a range of different sizes. Typically, their size is measured in micrometers (μm). One micrometer or micron is one millionth of a meter, i.e. 0.0001 millimeters. The expression "PM" is usually used to define particle size. PM stands for "particulate matter" and is based on the U.S. standard for particulate matter. Imagining particle sizes is not very easy. They are divided into the following rough categories.
- Large particles: PM 10 = Dust, pollen, mold spores
- Medium particles: PM 2.5 = Fine dust, large spores, and other organic contaminant particles
- Small particles: PM 1.0 and smaller = Very fine dust, combustion particles, nanoparticles, bacteria, viruses, and small spores
Important: Particles measuring PM 1.0 or smaller are respirable, meaning they can penetrate the cell membranes of the alveoli (small air sacs in the lungs) and so enter the bloodstream. From the bloodstream, these particles enter vital organs (e.g. the heart), where they can accumulate and make you sick.
Six advantages of optimally purified air
- Pollutants are removed from the air and the burden on the human body is reduced: greater wellbeing in everyday life.
- Allergic reactions are reduced or avoided completely: people with asthma or allergies can breathe easily.
- The air indoors seems fresher and cleaner and is more pleasant to breathe: fresh air for a healthy life.
- Tiredness and lack of concentration are reduced: greater efficiency when working and doing hobbies.
- The risk of respiratory diseases falls: breathe safely.
- Used, sticky air is purified: the air feels fresher, healthier, and no longer smells stale.
Stadler Form is a specialist for indoor climate and healthy air at home and the purity of indoor air is an important issue to us. We have been working intensively on the purification of air for years. The results of our research and efforts are the air purifiers Roger and Roger little, which can remove particle and gas pollution from the air with the help of the Dual Filter™. What's special, is the air quality display that is integrated on the front of the air purifiers. It shows the current air quality in the room at a glance. Blue signifies good air quality, orange means medium air quality, and red stands for poor air quality. If Auto mode is activated, Roger and Roger little control the intensity of the fans themselves so that the air always remains perfectly purified. The life span of the filter is 8–12 months and a necessary change is indicated via the integrated filter display. Both air purifiers are manufactured to high quality standards and are easy to clean. The powerful motor ensures great air circulation and thus an excellent cleaning performance.
The Dual Filter™ from Stadler Form is a combined particle and gas filter. It has a multilayer construction. A special fleece filter or HEPA filter is responsible for removing particles. A layer of activated carbon absorbs various gaseous pollutants from the air. The advantage of the filter is that both filters have an even flow-through and thus high quantities of particles and gases are removed. The handling is also very simple: just one single filter needs to be replaced after 8–12 months.
The air purifier Viktor dispenses with a classic HEPA filter and cleans the air using an electrostatic filter. The advantage of this is that it is not necessary to purchase a new main filter, and only the prefilter and activated carbon filter need to be replaced. The main filter (in this case the HPP filter) can simply be cleaned with water and hand soap.
Here some important points to consider when buying an air purifier.
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.
