Independent laboratory tests

Professional air purification systems from ETS Products Group

Independent laboratory tests

The air purifier market is currently confusing. Due to the lack of regulations, every supplier offering "HEPA filters in a housing with a fan" becomes a specialist - most systems are untested.
A reference to an approved study or CE declaration, which in most cases is a self-declaration, says nothing about the effectiveness of the system in terms of the safe removal of pollutants.

An institute for aerodynamics, for example, cannot replace a laboratory that carries out real tests with viruses and bacteria. It can only prove the air distribution and circulation in rooms.

Therefore, only air purifiers whose effectiveness has been proven by independent testing laboratories testing with viruses, bacteria and pollutants should be used in public areas.

The tests should refer directly to the respective product. Comparative assumptions or the reference to the standard of a filter says nothing about the real performance of the respective device! In the event of a problem, the operator should be able to provide evidence!

When comparing air purifiers, the first question should therefore be a device-related test for viruses, bacteria, dust and odours as well as a test of the air volume!

The effectiveness of the ETS air purification systems was tested in test cycles in independent laboratories with viruses, bacteria, dust and formaldehyde (= odour).

The specified air volume (CADR - Clean Air Delivery Rate) has also been confirmed and documented in tests.

SGS certificates air purifier

SGS, headquartered in Switzerland, is the world's leading inspection, verification, testing and certification company. The SGS network consists of more than 2,600 branches and laboratories worldwide and more than 89,000 employees.

Guangdong Institute of Microbiology Certificates Air Purifier

The state-supervised institute in China has international recognition among microbiologists. The institute conducts research and testing in the fields of microbiology, environmental science and materials science. It was founded in 1964 and is one of the leading institutes in these fields.

All test results of the ETS air purification systems can be queried and verified for validity by dealers and consumers at any time on the online portals of the testing organisations.
Valid CE declarations are available for all systems: The complete systems comply with international standards and meet all current standards and regulations.
All HEPA filters used are approved according to EN 1822 or ISO 29463.


Test Note: H1N1 and H3N2 viruses were used for the test as SARS-CoV-2 viruses are not yet available as inactive test viruses. H1N1, H3N2, SARS-CoV-2 belong to the RNA virus class and have the same structure. The bacteria used are DNA based. The determined killing and air purification results are completely transferable to all viruses and bacteria in the air. UV and plasma destroys the cell envelope, RNA and DNA of each virus and bacterium equally.
