The patented Biow technology

The processes inside a Biow device are very complex. If you're not an expert in the field of molecular biology, you'll probably have trouble understanding them. However, we think it is immensely important to understand how Biow works and the impact its functions can have on your body. It pays to understand Biow's patented technology to the best of your ability so that you can best appreciate the individual effects of its system of action.


Biow works fully automatically. Through various sensors, it measures the concentration of harmful particles in the air and adjusts its working intensity accordingly. This creates an optimal indoor air quality. Besides cleaning the air, the device also helps maintain the temperature and humidity in the room at a healthy level. Inside a Biow device, various processes take place to remove particles from the air. These include:

  • Filtering
  • UV treatment
  • Ionizing the air
  • Sterilization


Hepa Filter Mode of Action

As soon as air enters the Biow device, it is gently filtered. All filterable molecules are removed from the room air with special filters like a HEPA H13 filter and a subsequent activated carbon filter process.

With the Hepa H13 filter (High Eefficiency. Particulate Air [filter]) is a pleated, mechanical filter. The high-efficiency filter has a filtration efficiency of at least 99.97%. This means that out of 10,000 particles that are passed through the filter, only a maximum of 3 particles leave the filter.

The subsequent cleaning by means of an activated carbon filter ensures the removal of odors and so-called volatile organic compounds (VOC). These compounds adhere to the charcoal and are trapped in microscopic pores on the surface of the charcoal.

Patented filter process

However, many molecules are so small that filters cannot catch them. Biow manages to do that with a special method called plasma ionization. The ionization of the air that is sucked in causes particles inside the device to become electrically positively and negatively charged. This causes the particles to combine and clump together, so to speak. This joining of particles makes them larger and therefore filterable.

Afterwards, UV light is used. This ensures that the outer protein coat and DNA of the allergens, germs, bacteria and viruses are destroyed. Without DNA, no organic material can survive and dies. For sterilization, the air can then be heated to over 200 degrees before exiting the device.

The best part is that you won't notice any of this. You generally don't feel any suction from the air being sucked in, you don't feel any airflow from the air coming out, and you don't notice any of the radiation or heat processing going on inside the patented device. In addition, Biow operates almost silently.

Biow and the effect on allergies

Allergens are by no means - as often assumed - mostly of natural origin and only seasonally occurring particles. Most allergens are molecules from industrial exhaust or other emissions caused by us humans. Biow's special filtration processes quickly capture allergens and render them harmless.

Biow and the effect on bacteria and viruses

Even though germs, bacteria and viruses are microscopic, they are living things. This means that these single-celled organisms can also reproduce. While bacteria are comparatively large, viruses are often so small that they cannot be filtered. Due to the ionization of the particles, viruses and bacteria join together to form larger clusters. In the process, they increase in size. This enables our special filters to pick up the "virus clumps". The pests are then rendered harmless by means of UV radiation.

Biow and the effect on deposits in the bloodstream

The various molecules and components in the air are drawn into our bodies through breathing. Many harmful molecules can be broken down by the body, evolutionarily the human body adapts to its environment. But in our fast-moving times, so many new dangers arise on a molecular level within a very short time that our bodies have no defence mechanisms against these pests. A good example is the fine dust pollution. While an increased concentration of fine dust was rather rare 50 years ago, it is now a common problem in most urban zones in our latitudes. Our body has problems with this permanent exposure. It can break down some of these particles, but not all of it. And when we are permanently exposed to increased levels of particulate matter, the molecules that are not broken down accumulate in our organism. This accumulation of harmful particles can lead to too much stress on the body - blood pollution. Biow ensures that the air you breathe at home is as free as possible from such harmful particles. This means that the body does not have to worry about fighting off "new" particles, but can instead break down the old, stored molecules. Thus, Biow helps you reduce blood pollution and contribute to a healthier body.

Biow and the effect on moisture and mold

Mold spores are among the most common causes of illness within the home. They circulate in the air and settle on damp areas on walls. Particularly treacherous are undetectable mold infestations between the wallpaper and the wall. To prevent such cases from occurring in the first place, Biow filters the aforementioned mold spores from the air, among other things, and helps to reduce room humidity and lower the risk of mold.

Biow and the effect on nanoparticles

Nanoparticles, as the name implies, are tiny particles that range in size from a few nanometers. They include fine dust, industrial exhaust fumes and abrasion from car tyres. They can only be broken down by the body to a limited extent and are thus deposited in our cells. This places an additional burden on the organism. The ionisation of the particles described above makes filtering possible. Biow does this effectively and removes nanoparticles from indoor air.
