The effects of nanoeX have been recognized by experts
Various types of moulds enter houses along with people and air. Even if preventive action is taken in our everyday lives, it is often very difficult to inhibit the growth of mould, especially in humid environments. With nanoe™ X, we have experimental results1,2 that show we can inhibit the growth of the types of mould and bacteria commonly found in various places in the house.
1The results of experiments show that nanoe™ X is effective in inhibiting the growth of the following types of mould and bacteria commonly found in homes:
Mould: Trichophyton, Cladosporium, Malassezia furfur, Sporothrix schenckii, Exophiala jeanselmei, Absidia corymbifera, Rhodotorula rubra, Neurospora sitophila, Schizophyllum commune
Bacteria: Methicillin-resistant Staphylococcus aureus (MRSA), Listeria monocytogenes, Bacillus subtilis, Mycobacterium smegmatis, Nocardia asteroids, Neisseria gonorrhoeae, Salmonella enterica subsp. enterica, Haemophilus influenza, Campylobacter jejuni
2This verification was designed to generate basic research data on the effects of nanoe™ X on mould and bacteria in laboratory conditions, which are different from those found in actual use environments. It was not designed to evaluate product performance.
Verification of nanoe™ in Collaboration with an Independent Research Institute
Four types of viruses were inhibited by 99% in 6 hours
Viruses, either human- or animal-derived, are generally classified in four types. These four types of viruses were selected based on a virus clearance test, and the effectiveness of nanoe™ technology in inhibiting them was verified. The results indicate that nanoe™ has the potential to inhibit most highly resistant and unknown viruses.
Test Outline
The test was conducted in collaboration with Charles River Biopharmaceutical Services GmbH, a research laboratory that complies with German Good Laboratory Practice (GLP) standards.
The test was designed to predict inhibition effect against highly resistant and unknown viruses. In light of the likelihood of new viruses being discovered and becoming widespread, we classified the viruses following criteria (presence of envelope, genome, and size) based on a virus clearance test. Four types of viruses classified based on their physiochemical resistance were selected for the test. A comparison of nanoe™ exposure and non-exposure for these four types was carried out according to GLP standards.

Good Laboratory Practice (GLP): Standards to show that testing was carried out accurately and properly, with strict provisions for testing procedures, etc.
Verification of nanoe™ X effects with residential air conditioners
ODOURS
nanoe™ X reduced odours absorbed by fabrics such as curtains and carpets.
