The quick fix for hygienically clean air.
Continuous ventilation is one of the most efficient measures during the current COVID-19 pandemic to prevent the accumulation of pollutants such as aerosols (viruses, bacteria). Air purifiers are an effective and flexible quick fix, especially during the colder part of the year and in rooms that cannot be ventilated effectively.
The AirPurifier has been developed especially for retrofitting in rooms requiring additional air purification. The appliance is designed to handle rooms up to 120 m2 in size (4x air filtration rate) and uses a high-performance HEPA filter H14 (DIN EN 1822) in combination with an activated carbon filter (AirPurifier) or a particulate matter/pollen filter (AirPurifier max). Its range of possible applications includes classrooms, preschools, restaurants, conference rooms, offices, medical practices and fitness centres.

Funding for air cleaners & temporary financial assistance
Conditions, amounts and applications?
We have the answers:
In Germany, funding for school equipment is the responsibility of the federal states. This overview shows which states currently provide funding for air cleaners.
Temporary COVID-19 financial assistance
for small and medium-sized enterprises
The acquisition and operating costs for hygienic measures are eligible for funding. This includes the cost of investing in air filtration systems/air cleaners.
We have answers to the most important questions concerning COVID-19 financial assistance:- What are the conditions?
- What amount of funding is available for air cleaners?
- Where, how and when should you apply for funding?
- 5-point checklist for funding applications.
Ideal where ventilation alone is not enough
Regular ventilation is vital in indoor areas occupied by large numbers of people, particularly in light of the current COVID-19 pandemic. It ensures that stale, virus-laden air is constantly replaced with fresh, clean air. Air cleaners can be used wherever thorough ventilation is not possible. Good air purifiers must be capable of completely circulating and filtering all air in the room at least four times (ideally six times) per hour.
HEPA, activated carbon & more
The core of the AirPurifier is the filtration system. It cleans dust, particulate matter, bacteria, viruses and other pollutants from the air. The prefilter removes large particles, such as dust and hair, from the indoor air. A prefilter collects volatile organic compounds (VOCs) from the air and the activated carbon in the filter even binds unpleasant odours. The HEPA filter (H14) cleans particulate matter from the indoor air and also removes pollen, mites, animal allergens, mould, viruses and bacteria from the air.
AirPurifier facts
AirPurifier reduces the concentration of aerosols in the air
Scientifically verified
Real measurements confirm the outstanding efficiency of the AirPurifier. Average readings show that this air cleaner reduces the concentration of a test aerosol by 80%, and locally by up to 90%, within 30 minutes. A recognised hygiene institute confirmed that airborne viruses were reduced by 99.995%.A good air cleaner must meet four main requirements.
- Good air purifiers must be capable of completely circulating and filtering all air in the room at least four times (ideally six times) per hour. With lower air exchange rates, only fine dust or pollen can be removed from the room air; the aerosol concentration cannot be sufficiently reduced at lower rates according to the current understanding.
- Genuine HEPA fine filters in line with the DIN EN 1822 filter standard: The term HEPA filter is not protected, meaning that many supposed HEPA filters do not deliver what they promise. A true HEPA H14 filter separates up to 99.995% of the aerosol particles and is certified according to DIN EN 1822.
- Noise levels: An appliance that does not create a disturbance won’t be switched off (e.g. in the classroom, where an atmosphere of concentration is required). According to VDI 6040 and DIN EN 15251, the maximum allowable A-weighted sound pressure level in classrooms is 35 dB(A), which corresponds roughly to the volume in a library or a quiet bedroom.
- Designed in compliance with VDI 6022: In order that air purifiers and air handling systems do not themselves become a source of air pollution over time, they must be designed and built appropriately. The use of suitable, long-lasting and easy-to-clean materials is especially important. It is therefore always important to look for an air purifier designed in conformity with VDI 6022.
