What pollutes the air?

In simple terms, the air is polluted by solid particles and gases. These include various allergens, pollen, bacteria, viruses, molds, dust, dust mites, fumes from cooking, furniture, pets, cleaning products, toners, markers, glues, fireplaces, emissions from cars, factories, manufacturing plants, ironworks... .etc.

Why do self-inflammatory processes occur in the body?

The body can eliminate solid particles that are captured by microphages in the human body. If the body is too flooded, the macrophages do not have time to protect the organism and eliminate them from the body. They enter the body, causing inflammation that enters the bloodstream and floods the body. Thanks to the AIR+, which captures particles up to 0.1 PM, you can reduce the risk of self-inflammatory processes.

What maximum and minimum outside temperature can I put it at?

It is advisable to place the BUBBLE in a comfortable temperature environment (in spaces between 18-25º), avoiding direct exposure to the sun since heat accumulates inside. If it is placed outdoors, the minimum temperature that the material supports is -30ºC.

We have decided to provide our customers with a safe environment and therefore clean and healthy air. For this purpose, we chose the AIR+ 430S. It is a unique device, probably the only one in Slovakia that I know of that can effectively fight viruses, toxins with a filter that is more effective than HEPA filters. I recommend it to any establishment if you want customers to feel safe and come back.¨

Why buy an AIR+ purifier?

We spend between 80% and 90% of our time in the interior spaces that are highly harmful to the body, where chemical pollutants are produced, either by inadequate ventilation or existing sources of contamination (tobacco, insecticides, paints, concentrations of organic gases, cleaning products, furniture, heat sources...). Typical components of the indoor air we breathe are: environmental smoke made up of NOX, SOX, chemicals emissions, VOCs, biological pathogens (viruses, bacteria, molds) and inert particles. Airborne particles are a complex mixture with a variable size ranging from 0.005 to 100 μm.
In general, the smallest particles have the most toxic elements in their composition, such as heavy metals, viruses, bacteria or organic compounds with a carcinogen capacity. hat's why the AIR+ air purifier is needed wherever people hang out, restaurants, cafes, but also waiting rooms, libraries, business centers, or meeting rooms, .


AIR+ is a certified device subject to European standards. Zonair3d products and all their components have been certified by entities with international recognition. All our production departments have obtained ISO 9001: 2008 and ISO 14001 certificates.

Zonair3d filters have been tested in laboratories with the current European EN779: 2012 certification and the corresponding US ASHRAE 52.2 certification, thus certifying the absolute efficiency of the filter.
