Advantages of Nano-Flow air purifiers


THE ONLY AIR PURIFIER on the Czech market with confirmed efficiency AGAINST VIRUSES

The efficient photocatalytic destruction of viruses is in principles described in peer reviewed literature and is also supported by number of experiments.
In the case of our product the virucidal function of the LED UVA illuminated TiO2 surface on the metal panels inside the air cleaner, it was confirmed by a study conducted in the National Health Institute – Centre for epidemiology and microbiology. This is the system which is inside all NanoFlow air purifiers
The study proved antiviral effect after just 1 hour and virucidal effect after 3 hours of LED UVA light exposure. 


LOWERING the risks of transfer by AEROSOLS and hypothetical VIRAL INTAKE thanks to safe to being used AROUND PEOPLE without the need to vent the air

Absolutely crucial advantage of our technology is that it can function in public areas populated with lots of people and all this for 24 hours a day. Unlike UVC lamp or ozonisers after which use it is necessary to vent the area for several hours, our technology can work in a continuous mode and lower the risk of a viral infection through aerosols at all times. The lowering of the potential concentration of virus in the air is essential with respect to how severe the potential illness after acquiring COVID-19 may be. Continual purifying is key for all public spaces.

Even wearing a face mask won’t stop the viral transfer via aerosols, for the transfer it is enough when the infected person is just breathing and not talking. The latest research of institutions such as WHO is showing that the virus can survive in deposited aerosols on surface for couple of hours. This all leads to a conclusion that it is essential to clean the air in the continuous mode. The air purifier is therefore lowing the probability of spreading the virus as well as the dose of the potential infection. UVC lamps or ozonisers cannot stop the transfer and can be switched on only when the public areas are without people i.e. when they are closed. Infection through aerosols is today considered even more dangerous than through surfaces.


DESTRUCTION of the viruses not just CAPTURING, and on a NANOMETRES scale

Most air cleaners on the market is capturing the pollutants via physical filters. With regard to this point it is urgently needed to mention following facts.
Firstly, as a consequence of using filters there is the necessity of replacing them, this is increasing the running costs of up to hundreds of dollars a year. If there is a lack of minding the replacement, the filters will become saturated and stuck and become source of pollution and microbial growth. The air purifier becomes polluting its surroundings.
Secondly, even the best filters on the market are only capable of capturing particles larger than 0.3 micrometre. That means that the current air purifiers are incapable to capture coronavirus, because coronavirus is much smaller, measuring only about 0.050 to 0.140 micrometre. 


low MAINTANANCE + very low RUNNING COSTS + exceptional LONGEVITY

The absence of physical filters has yet another great advantage which is that unlike all the other air cleaners there are no extra maintenance costs. The impurities are destroyed on a molecular level and the final product is just CO2 and H2O.

With this in mind, it is obvious, that you don’t have to spend money on replacing filters. Our product consumes minimum electricity (ca. 5 cents a day) and there are the lowest possible running costs. Because the coating is not consumed during the reaction the expected longevity of our products are superior. 


WORKS against VIRUSES and all the other POLLUTION

As mentioned above the biggest advantage of Nanoaircleaner air purifier against other air cleaners is its confirmed efficiency against viruses. Air purifier Nanoaircleaner effected against all the other impurities such as bacteria, moulds, acari, dust particles or allergens. In general, it is true that, air cleaners improve the air quality and help prevent asthma for instance. But only photocatalytic based air purifiers can also reduce carcinogenic gases like formaldehyde, toluene or NOx.



It is worth noting that RETAP s.r.o. is not the only manufacturer that is using photocatalysts in their air cleaners. Although, only RETAP is using photocatalysis as the main and sufficient solution. The others are using set of filters and they need more energy to pass the air through which is increasing the energy consumption and noise. RETAP in its Nanoaircleaner product can enlarge the area of the surface coated with photocatalyst and in a sense that is how RETAP can increase the efficiency. It is important to make sure that the quality coating is certainly coming from our factory. Be aware and check, fake products can be harmful to use.


Zero OZONE production

There is a common argument against the photocatalytic based air cleaners that there is ozone produced as a side product. We have consulted this with researchers in the field and were assured that the ozone is formed in case of ozonisers (different kind of technology). Our air purifiers produce no ozone.


DESIGN and ANTIBACTERIAL surface of the air purifier

Our air cleaning solution is not revolutionary just in the technology but also in its design. Nanoaircleaner offers and alternative look, unlike a typical white-goods, the heart-core is encapsulated in a nature-like envelope like wood, glass or stainless. Our air cleaner is a perfect match with modern interiors and will become a non-disturbing part of the interior rather than another plastic box.


INNOVATIVE approach regarding the air cleaning - PORTABLE or CONFERENCE TABLE model

Nanoaircleaner brings on the market innovative products not just with respect to the technology but the whole concept is innovative. Our customers can now choose between different designs and also a wall-mounted version. There is also a portable luggage-style type, glass and stainless or one with a magnetic white board intended for education centres like schools.


CZECH product and know-how

Market with air purifiers is an example of a saturated and fragmented market. This means that there are still new companies entering the market and there is no major player. The biggest players are big brands such as Philips, Xiaomi, Rowenta, Dyson, Sencor or Sharp. So how is it even possible that a small Czech company can succeed?

Czech Republic is a world leader in nanotechnologies, which are at the core of manufacturing our photocatalytic based air purifiers. Air cleaners Nanoaircleaner were developed together with the best Czech scientists in the field. TiO2 photocatalyst is coated onto metal panels in a form of a nanoparticulate film. This coating is done in several steps at various temperatures and thicknesses, so the coating has the desired ideal properties.
