Frequently asked questions

Below you can find the answers to the most frequent questions we receive.


How does UV water treatment work?

Living organisms in water are exposed to UV light during the UV water disinfection process when water flows through a UV water treatment system. UV radiation damages the microorganism’s genetic code and rearranges its DNA and RNA, rendering it incapable of functioning and reproducing.

How does UV air treatment work?

UV air purifiers are machines that collect air and pass it through a filter using UV light technology. The air is subsequently subjected to UV-C light after passing through a tiny interior chamber. The air is then filtered once more by several air purifiers before being returned to the space.

How does UV surface treatment work?

By lowering the carbon content to under 20%, UV treatment makes surfaces highly hydrophilic and cleans the polluted hydrocarbons.

Which wavelength of UV is optimal?

The strongest capacity to kill cells was demonstrated by UV light at 250 nm, with a median lethal dosage (LD50) of 120 mJ/cm (2). The LD50 progressively increased as the wavelength grew.

What happens when UV hits the water?

Some UV-C light penetrates the water and is absorbed by germs in the water, such as bacteria and viruses, when UV-C light is shone on water or if the bulb is submerged in water. These microorganisms are destroyed when UV-C light is absorbed by them, purifying the water.

How does UV affect air quality?

By eliminating mold and germs, UV lamps clean the air, which is then directed for circulation into the HVAC system. By producing a light that damages pathogens’ DNA, UV lamps eliminate pollutants. The contamination is no longer regarded as dangerous since it is unable to fix itself.

Does UV light eliminate dust?

Using UV light disinfection, you can control allergies, dust, mites, viruses, bugs, and infections without using any chemicals or harming the environment.

How do I know if my UV light is still good?

A UV lamp’s exposure dosage is expressed in joules per square metre (J/m2) or millijoules per square centimetre (mJ/cm2), respectively. According to the International Ultraviolet Association (IUVA), dose amounts between 10 and 20 mJ/cm2 will render bacteria, viruses, yeasts, and mould inactive (and their spores).

How long does UV lamps last?

After 9,000-12,000 hours or roughly every 12 months, we advise replacing your UV light. For people with allergies and other respiratory issues, a yearly replacement plan is also advised.

How long does UV take to purify water?

UV water purification happens quickly! Bacteria and other waterborne organisms are eliminated within 10 seconds of the water passing through the UV chamber. UV purification is one of the best alternatives to boiling if you need to eliminate pathogenic organisms from the water. While this form of water treatment removes germs, it is unable to remove any other contaminants that pose a threat to your health.

Are UV water, air and surface systems worth it?

Overall, UV treatment is a fantastic solution to address your company’s objectives for facility cleansing throughout the whole facility. It may be used for both point-of-use and whole-facility water, air, and surface treatment applications and has been shown to be one of the most dependable, economical ways for disinfection. UV lamps have a high potential for eradicating germs, mould, and viruses under the appropriate circumstances and with the right installation. As the two of them function together, your building will become a lot healthier.

Does UV clean water?

The majority of microbial contamination in water may be eliminated with a water treatment system that uses Ultra Violet (UV) radiation.

Does using UV lights waste a lot of electricity?

This will be according to the bulb’s wattage. The annual power consumption of a 100W UV lamp is 0.5 kWh. Thus, even though it does use some power, it’s still a wise investment. As opposed to standard bulbs, they save 30–40% on energy.

How can you tell if a UV bulb is blown?

Simply by looking at the ductwork area where your UV light is located, you should be able to tell if the bulb is still working. Tiny seams or openings in the ductwork around the light will allow you the opportunity to see the blue light operation.

How do you maintain a UV system?

Every year, replace your Ultraviolet lamp. Frequent lamp replacement is the most crucial component of UV system maintenance. The UV lamp, which powers the entire UV system, must be kept in good working order for the system to be able to keep harmful viruses and germs out.
