Yes, they do. The UV-C radiation emitted by the ozone-free bulbs built into the germicidal lamps destroys all microorganisms, including viruses.

UV-C radiation acts on the surfaces that it can reach, therefore it is impossible to clearly define the validity of such a solution. Rotating objects during exposure may be risky for humans due to the harmful effects of UV-C on the skin and eyes.

No, it cannot. A direct radiation germicidal lamp should be used additionally to disinfect the surface.

For air disinfection in the presence of people, you should choose UV-C flow germicidal lamp (NBVE, ASEPTOR Basic, GERMIPROTECT series). 

For surface disinfection in the absence of people, choose a direct radiation NBV lamp.

Air and surface disinfection is provided by the dual-function germicidal lamps NBVE 60/30 and NBVE 110/55. The first function disinfects the air in the presence of people. The second function directly disinfects the surface in the absence of people. Both functions can work separately or simultaneously.

Check the technical data table so as to choose the appropriate model for your room. You can find the technical data in catalogues of germicidal lamps - downloadable in pdf at ultraviol.pl

The best bet would be a flow germicidal lamp for air disinfection. Viruses are mainly transmitted by air. The single purpose UV-C flow germicidal lamp can work in the presence of people, for instance: ASEPTOR Basic or NBVE series. These lamps are 100% safe for use around people. 

A dual-purpose flow germicidal lamps with an external UV-C bulb NBVE 110/55 or NBVE 60/30 are also a good choice. Remember, the 2nd function (direct radiation, external bulbs) can work only when people are not around.

You can also apply a direct-acting NBV lamp for disinfecting surfaces in the absence of people. It is worth bearing in mind that long-term exposure to direct UV-C radiation may lead to discoloration of the equipment and degradation of plastics.

The best bet would be a flow germicidal lamp for disinfecting the air being a carrier of microorganisms.  The single purpose UV-C flow germicidal lamp can work in the presence of people, for instance: ASEPTOR Basic or NBVE series. We strongly recommend ASEPTOR Basic series, because it is silent, perfect for home conditions. 

There is no need to use the remote control. Germicidal lamps can be turned on with a switch located on the housing or the lamp (mainly mobile versions) or can be connected to the electrical installation. 

The switch can be placed on the wall inside or outside the room (wall-mounted, ceiling-mounted types). It is worth taking under consideration the type of lamp. Direct-radiation lamps or dual-purpose lamps turned on by the switch located on the wall, should be protected from accidental switching. 

SARS-CoV-2 is killed very fast by UV-C lamps. For the reduction of microorganisms to be at the highest level, the single-purpose flow germicidal lamp by Ultraviol should work as long as possible (it is intended for continuous operation, especially in rooms such as corridors, locks, vestibules due to the high level of the air exchange - entry and exit).

Check the scientific research of our UV-C lamps here.

Direct radiation UV-C germicidal lamp NBV series should irradiate the surface during the absence of people. Already several minutes of irradiation leads to the significant reduction of microorganisms. Our experience shows that the 100 % reliable confirmation of the disinfection effectiveness can be achieved by the tests before and after using the germicidal lamp. The further the irradiated surface is from the UV-C light source, the weaker the effect. Exposure time should be extended when the distance between the lamp and the exposed surface is greater.

Mobile lamps (with the letter "P" or “M” in the symbol) have a power cord ended with a socket plug. Wall-mounted (“N” or “W”) and ceiling (“S” or “W”) have cables terminated with a junction box to be connected to the electrical installation.

No, both devices can work simultaneously in the room.

The filter should be replaced when it is dusty. We recommend doing this at least once a quarter.

No, they do not. Renowned manufacturers of UV-C light sources declare that the UV-C bulbs do not emit ozone.

Yes, there is such a risk. This is due to the very strong biocidal activity of UV-C radiation. Plastics can discolour just as they do when exposed to sunlight. Also, the rubber elements and gaskets can get more inflexible and crack.

We should protect the areas we are concerned about by covering them. UV-C radiation has an effect only on the surface and does not penetrate deeper. The surfaces that are not supposed to be irradiated should be disinfected with chemicals.

In the flow germicidal lamp, the light sources should be changed every 8 000 / 9 000 hours of operation. Depending on the power, their cost ranges from several EUR to several dozen EUR. The cost of a simple filter that protects the interior of the lamp against dust and insects is 0.80 EUR / pc.

No, it is not. The smell is associated with "burning" by UV-C radiation of dust particles as well as chemical compounds in the air.

It depends on the particular series of the device. Generally, we can assume that: wall-mounted lamps (N) and ceiling-mounted lamps (S) have ca 1 m power cable while mobile lamps (P) have ca 3 m power cable.

You can buy the RC set for a wall-mounted lamp (N) and a ceiling-mounted lamp (S).

No, they do not. Loudness is highly subjective and depends on the background against which it is measured. Direct radiation germicidal lamps NBV series do not emit any sound. NBVE flow-through germicidal lamps may be audible depending on the power.
If you care about the silence we can highly recommend the ASEPTOR Basic UV-C flow lamps.

There is no such requirement.

Yes, you can come in right away. There is no need to wait.

Industrial germicidal lamps are made of materials adapted to the harsh conditions prevailing in the rooms of the food, cosmetics, pharmaceutical industry, etc. They are equipped with light sources generating the same UV-C radiation as the germicidal lamps of the NBV and NBVE series. They are also more powerful. NBV and NBVE lamps are recommended for doctor's offices, beauty salons, or houses and flats. GermiProtect GP4x55 flow germicidal lamps are recommended for large volume rooms, approx. 250 m3, communication routes, production halls, etc.

The single-purpose UV-C flow germicidal lamp disinfects the air (one function). 
The dual-purpose UV-C flow germicidal lamp is a flow lamp equipped with an additional external UV-C bulb for surface disinfection. The first function disinfects the air in the presence of people, the second directly disinfects the surface during the absence of people. You can use both functions at the same time, provided that there are no people, animals, or plants in the room.

The lamps do not differ in anything apart from the presence of a counter. You can purchase a lamp without a working-time counter. It is not required for the proper functioning of the lamp. However, it facilitates to indicate the moment of UV-C bulbs exchange (after each 8 000 / 9 000 hours).

Both counters count the lamp operating time. 

In NBV UV-C direct radiation lamps the “L” digital counter is located on one side of the lamp body. It has two diodes and enables acoustic signalization of the moment to replace the UV-C bulbs.

In NBVE germicidal lamps the “L” mechanical counter (s) is/are located on the lamp body. It shows the operation time of the lamp (no acoustic signaling).

The LW counter has a LED display and can be added to NBV and NBVE lamps, it signals the moment of replacement of the UV-C bulbs with acoustic signaling.

The air purifier traps alive microorganisms on the filter (it works passively). The NBVE flow germicidal lamp produced by Ultraviol with the use of UV-C radiation irreversibly destroys (kills) microorganisms and their spore forms (it works actively).
