Why Do You Need an Air Purifier?
The air we breathe indoors can be filled with various pollutants, including dust, pet dander, pollen, smoke, and even microscopic particles like bacteria and viruses. Inadequate indoor air quality has the potential to result in various health concerns, such as triggering allergic reactions, exacerbating respiratory conditions, and contributing to a host of other health-related issues.

How Do Air Purifiers Work?
Air purifiers employ a variety of mechanisms to purify the air, each with its unique approach to enhancing indoor air quality:

High-Efficiency Particulate Air (HEPA) Filters: HEPA filters are highly effective at trapping particles as small as 0.3 microns. They are particularly useful for capturing dust, pollen, and pet dander.

Activated Carbon Filters: This filtration system excels in the removal of odors, gases, and chemicals from the air, making it highly effective in maintaining a fresh and clean indoor environment.

Ultraviolet (UV) Light: UV-C light is used to kill bacteria and viruses, rendering them harmless.

Ionic Purifiers: These generate negative ions that attach to particles in the air, making them too heavy to remain airborne. The particles then fall to the ground where they can be vacuumed or swept away.

Breathe clean. Live healthier.

The trigger of Asthma

Asthma is a long-term inflammatory disease of the airways of the lungs, that can be caused by a variety of factors, including allergies, exposure to irritants, and genetics. If you or your family have a history of asthma or allergies, you may be at a higher risk for developing the condition as well. Additionally, young children are especially vulnerable to developing asthma due to respiratory infections. Air purifiers is capable to help removing allergens, irritants, and toxins from the air, which making them an important tool for asthma sufferers.

There are many different things that can trigger an asthma attack. Some common triggers include air pollution, dust mites, exercise, mold, pests, tobacco smoke, strong chemicals or smells, and certain occupational exposures. If you or someone in your home has asthma, it is important to be aware of these triggers and take steps to avoid them. Air purifiers can help to reduce the triggers and thus reduce the risk of an asthma attack in close environment and reduce the probability of developing asthma from allergic rhinitis.

Allergic to dust?

If you’re allergic to dust, you’re not alone. Up to 130 million people suffer from dust allergies. But these allergies are caused by tiny particles, body fragments and waste from house dust mites, such as mattresses, pillows, or carpet. While it’s hard to get rid of these pests, there are measures you can take to get rid of dust mites living in your home textiles. Since dust mite particles often become airborne, by using an air purifier with a high-efficiency particle air (HEPA) filter would help removing these and other allergens from the air.

Air purifiers could remove dust mites and other allergens from the air, making it easier to breathe for allergy and asthma sufferers. Air purifiers has also the ability to help prevent sickness by killing harmful airborne germs.

Corona pandemic at schools: air filters should reduce risk of infection – not all devices are suitable

Air purifiers against corona: reducing the risk of infection?

Researchers at Goethe-Unversity Frankfurt have investigated various mobile air purifiers. To do this, the team led by Joachim Curtius,

Professor of Experimental Atmospheric Research, set up four air purifiers in a school class of 27 students for a week. The air purifiers had a simple pre-filter for coarse dust and lint, as well as a class H13 HEPA filter and an activated carbon filter.

The result: air purifiers can reduce aerosol concentrations in a classroom by 90 percent in half an hour. “An air purifier reduces the amount of aerosols so much that in a closed room even the risk of infection by a highly infectious person, a superspreader, would be reduced very significantly,” Joachim Curtius sums up after a model calculation based on the measurement data. (Colds and Corona: Regular ventilation in winter helps prevent infections)

Air purifier against corona: sensible technical solution

A study by the German Federal Armed Forces in Munich also came to a similar conclusion. In the Munich study, Christian Kähler of the Institute of Fluid Mechanics and Aerodynamics tested a device with a large volume flow and high-quality H14 filters. According to the study, the room filter had a filter combination that ensures that aerosol particles with a diameter of 0.1 to 0.3 micrometers are separated from the room air by 99.995 percent. (Corona in asthma, COPD and diabetes: How dangerous is the condition for high-risk patients?)

“The results show that aerosol concentrations in a room 80 square meters in size can be reduced to low levels anywhere within a short period of time,” the authors conclude. Accordingly, certain air purifiers are a sensible technical solution for greatly reducing infection risks  from aerosols.

Air purifier against Corona: It depends on the filter

But not all air purifiers are equally suitable. Who plays with the idea of acquiring such a room air filter, should therefore inform themselves sufficiently before the purchase. For example, filters installed in ventilation systems tend to be less suitable. This is because the classic fine dust filters only separate about 50 percent of the aerosols.Better are so-called H13, H14 and ULPA filters. According to aerosol researcher and head of the Hermann Rietschel Institute at the Technical University of Berlin, Martin Kriegel, these filters clean the air almost particle-free.

Air purifiers against corona: also suitable for schools?

The filters could also be a possible alternative for schools. Hesse’s state government, for example, has already announced that it will support school authorities with ten million euros for the purchase of air purification devices. “These are to be purchased in particular for classrooms where it is not possible to ventilate sufficiently because, for example, windows cannot be opened,” explained Education Minister Alexander Lorz (CDU).

Experts from the Federal Environment Agency take a rather critical view. Hence, the Commission for Indoor Air Hygiene continues to advise classic ventilation. In a detailed statement, it says: “The highest possible supply of fresh air is one of the most effective methods of removing potentially virus-containing aerosols  from indoor spaces.” The conclusion: mobile air purifiers in classrooms or at home cannot replace active ventilation, but at best act as a supplement in individual cases. (Ventilation against coronaviruses: Can air purifiers reduce the risk of infection?)

Experts take a critical view of air purifiers

The cold half of the year is approaching and with it, air purifiers are being massively advertised. They are supposed to rid the indoor air of corona viruses. Experts say: Active ventilation is usually a better alternative.

Expensive model of air purifiers for private use are supposed to remove up to 99.99 percent of possible corona viruses from indoor air. Such devices are just massively advertised. The consumer magazine “Super.Markt” of the Rundfunk Berlin-Brandenburg (rbb) has scrutinized four products and asked experts about them. These doubt the sense of such an investment and point to crucial gaps.

Thus it is possible to achieve a purification from Corona viruses in the air with built-in high quality filters. The crucial factor, however, is the amount of air that a single device can filter. Professor Martin Kriegel of the Technical University of Berlin , who has been studying the spread of airborne particles for years and, since Corona, also studies viruses in the air we breathe, takes a skeptical view: “One hundred cubic meters is nothing. If the device can do 100 cubic meters, then maybe I can get 0.5 percent change in overall risk, but not really make an impact.” Even if 400 cubic meters are cleaned, thorough and regular ventilation has the same effect as expensive devices, whose prices vary from several hundred to over 1,000 euros.

Low ionizer effect

Other devices advertise with a so-called ionizer. This is supposed to ensure that the air particles attract each other, clump together and thus become larger. This is supposed to make them easier to filter or cause them to sink to the ground more quickly. Professor Martin Kriegel is skeptical about this, too: “This effect, according to our studies here in our institute, is so small that it is actually negligible.”

Other manufacturers advertise UV-C rays for disinfection. That UV-C light neutralizes viruses has been known for a long time and is used in the disinfection of surfaces or to sterilize swimming pools. When cleaning air in indoor areas, however, it should be noted that UV-C rays are harmful to health when exposed directly to the skin and eyes. Professor Heinz-Jörn Moriske of the Federal Environment Agency therefore emphasizes “…that it must be prevented that any children play around with the devices and come into contact with the UV lamp.”

Conclusion of the rbb research

If you want to buy an air purifier, you have to pay attention to high-quality filters and the largest possible amount of air to be processed. Under this aspect none of the devices tested by the rbb could convince – despite the high purchase costs. Professor Moriske of the Federal Environment Agency sums up: “These air cleaners make sense as a supplement or in rooms where I simply cannot ventilate via windows… In individual cases, this can make sense. But please do not use it as a substitute for active ventilation.”
