In a class of its own when it comes to diluting the virus concentration

Not just a “Corona-era” phenomenon, even though in a class of its own when it comes to diluting the virus concentration.

 

Up to four times quicker than the closest competitor

UniqAir removes viruses, aerosols and contaminants from a space up to four times quicker than the closest competitor.

With the Technical Research Centre of Finland (VTT) we have tested the ability of our technology in lowering the viral load. The aerosol used in testing was removed from the test space in half an hour.

The result is far superior when compared to a result of two hours achieved by a competitor. Half an hour to purify the test space is a result that can be seen to function believably also in a real-world use-case.

Not just a “Corona-era” phenomenon

  • UniqAir removes all the health threatening contaminants from the breathing air. In addition to the viruses this includes also other particles and gaseous compounds
  • The superiority of UniqAir is based on an innovative circulation of air combined with unique filtration technology
  • UniqAir is a proven effective and safe choice

 

Choose a safe filtration technology – avoid electrical filter technologies

It is also important to pay attention to the safety of the used purification technology. UniqAir filters impurities, including gaseous harmful substances, safely from breathing air. UniqAir does not produce any by-products from the filtration process.

Independent studies report about the risks related to competing technologies

Competing technologies such as cold plasma, plasma, UV-C, ionizing and photocatalysis are prone to produce different harmful by-products during the purification process. These by-products include for example ozone, nitrogen oxides, aldehydes, secondary organic aerosols, hazardous charged particles, and powerful oxidisers such as hydroxyl-ions. All the forementioned substances can in the worst case increase the risk of cellular damage and oxidative stress in the body.

 

Independent studies tell the following on problems related to different air purification and filtration technologies:

The disadvantage of some air purification methods is the secondary compounds which are harmful to health. Photocatalytic oxidation produces formaldehyde and acetaldehyde as secondary impurities (Hodgson et al. 2007; Mo et al. 2009). The plasmafiltration process, in turn, generates nitrogen oxides and ozone. The ozone concentration depends on the humidity. Van Durme et al. (2007) found that the ozone concentration ranged from 26.6 ppmv (RH 45%) to 49.9 ppm (dry air). Ragazzi et al. (2014) found that using the plasma method, only 2-4% of the methyl-ethyl-ketone was converted to carbon dioxide, with methyl nitrate and 2,3-butanedione being formed as by-products. Similarly, treatment of toluene and limonene as formic impurities generates formic acid and carboxylic acids (Hoe-ben et al. 2012). The use of electrofiltration can generate dangerous charged particles and new impurities such as ultra-smallparticles and ozone (Guieysse et al. 2008). Waring & Siegel (2011) investigated an ionizer installed in a 27 m3 living room. This ionizer emits 3.3 ± 0.2 mg/h of ozone. The research team found that the use of an ionizer increases the concentrations of both ultra-fine particles and ozone.Ozone itself is harmful to health (EPA 2013; WHO 2005). When using separate ozone generators, the concentrations are usually high and harmful, in which case precautions must be taken – ozonation should never be used in the presence of humans or animals (Leppänen 2017). As a general rule, ozonation is not recommended for indoor use as a solution to mold problems, as a mold cleaning effect or to prevent mold growth. Ozonation should only be used in special situations, for example for deodorization (Leppänen 2017). Oxygen radicals formed by ozone react with chemical contaminants to form harmful secondary impurities and radicals such as aldehydes, ketones, organic acids, hydroxyl and nitrate radicals, primary and secondary ozonides, α-hydroxyketones, and α-hydroperones. Ozone is also generated in an air purification method based on ultraviolet radiation (Zhang et al. 2011). Zhao et al. (2013) found that many secondary impurities, including aldehydes, are generated by UV irradiation. UV light with wavelengths of over 300 nm are known to promote the formation of SOA (Secondary Organic Aerosol) particles.(Presto et al., 2005), (Kroll et al., 2006). SOA can cause or enhance negative health effects in humans.(Poschl, 2005), (Joe L. Mauderly & Judith C. Chow 2007), (Hallquist et al., 2009), (Wolkoff, 2012). In particular, toluene and other light aromatic compounds have been found to form dominant SOA precursors (Hildebrant et al., 2009). SOAs are formed from the oxidation products of VOCs, and therefore the degradation of the VOCs may result in the formation of fine particulate matter (Choi, 2017).
