UV-C light is your next business idea

So why is UV-C such an amazing innovation in itself and how it can revolutionize our household cleaning?

First, let's present the problem. We do not have time, me, you, the bystander at the bus stop. We are all busy, be it by viewing TikTok or saving the world. If you are on my team, you would want to take some nice shortcuts to speed up the weekly chores. Ideally, the house gets clean on its own. One of my daily frustrations is the bathroom, mouldy grouting and anything in between. Any invisible bacteria sitting on my toothbrush or sleeping in my second-day-used towel. It has been weeks and months since I was contemplating a household cleaning innovation using UV-C light. You can either scroll all the way down to read about it at the bottom of the article or first learn more about UV-C light.

How many germs there are on a toothbrush and how long does it take to kill toothbrush bacteria with UV-C light?
Studies have shown that toothbrushes can harbour a wide variety of bacteria, including some that can cause oral infections such as streptococcus, staphylococcus, and candida. The amount of time required to kill toothbrush bacteria with UV-C light can vary depending on factors such as the intensity of the light and the type of bacteria present. Some UV-C toothbrush sanitisers on the market claim to kill 99.9% of germs and bacteria on toothbrushes in just a few minutes, while others may take longer. It's always a good idea to follow the manufacturer's instructions and use the device as directed. It's worth noting that while UV-C can be effective in killing bacteria on toothbrushes, it's also important to keep toothbrushes clean and store them properly to prevent contamination and in addition, to use them properly with good oral hygiene. Regularly rinse toothbrushes with hot water and store them in an open space after use. And, replacing toothbrushes every 3-4 months.

What intensity of UV-C light do I need to kill bacteria within 10 minutes?
The intensity of UV-C light required to kill bacteria within 10 minutes can vary depending on the type of bacteria and the distance between the light source and the surface. However, in general, a UV-C light intensity of at least 40mW/cm2 is typically considered to be effective for killing bacteria in this amount of time. It is also important to note that UV-C light intensity alone is not the only factor that determines the effectiveness of UV-C light in killing bacteria. Other factors such as the duration of exposure and the distance between the light source and the surface also play a role. Additionally, the type of bacteria is also important to consider, as some strains of bacteria can be more resistant to UV-C light than others.

How long can you be exposed to UV-C light?
The U.S. Occupational Safety and Health Administration (OSHA) has set a permissible exposure limit (PEL) for UV-C light at 0.1 milliwatt per square centimeter (mW/cm²) for an 8-hour workday, 40-hour workweek. Additionally, the American Conference of Governmental Industrial Hygienists (ACGIH) has set a threshold limit value (TLV) for UV-C light of 0.01 mW/cm² for an 8-hour workday.

Is ozone a byproduct of UV-C light?
Ozone (O3) can be a byproduct of UV-C light, specifically when UV-C light is used to disinfect air or water. Ozone can be generated when UV-C light interacts with molecular oxygen (O2) in the air or water, causing the oxygen atoms to recombine into ozone. UV-C light is a wavelength of light between 200 and 280 nanometers, and when it strikes oxygen molecules (O2) in the air or water, it causes them to dissociate, forming two single oxygen atoms. These single atoms can then combine with un-dissociated O2 to form ozone (O3). It is important to note that while ozone can be a byproduct of UV-C light, it is not always the case, and not all UV-C light sources generate ozone. Also, the amount of ozone generated will depend on factors such as the intensity of the UV-C light, and the amount of oxygen present.

It's important to note that the safe levels of ozone in indoor or outdoor air are defined by different governmental agencies and organizations and that the levels of ozone considered safe for human health are usually very low, usually around 0.05 - 0.1 parts per million (ppm) for indoor air, and it is not intended to be inhaled by humans.

What are the benefits of UV-C light over using bleach for cleaning?
  • UV-C light is more effective in killing microorganisms: UV-C light is able to disrupt the DNA of microorganisms, making it difficult or impossible for them to reproduce and survive, while bleach can only kill some microorganisms on contact. 
  • UV-C light is more versatile: UV-C light can be used to disinfect a wide variety of surfaces and objects, including air, water, and personal protective equipment, while bleach is mainly used for cleaning hard surfaces such as countertops and floors. 
  • UV-C light is more convenient: UV-C light does not require any physical contact with the surfaces to be cleaned, which can be a benefit when cleaning items that are hard to reach or that would be damaged by bleach. 
  • UV-C light does not leave any residue: UV-C light does not leave any chemical residue on the surfaces that it disinfects, unlike bleach, which can leave a strong smell and residue behind. 
  • UV-C light does not generate harmful by-products: UV-C light does not generate harmful by-products, as it works by disrupting the DNA or RNA of microorganisms and it is not toxic to humans, while bleach can produce chlorine gas and other harmful by-products if mixed with other cleaning products. It's worth noting that each cleaning method has its own advantages and disadvantages, and UV-C light disinfection should be combined with other cleaning methods to achieve the best results. Additionally, it's always a good idea to follow safety guidelines and consult with professionals in the field of UV-C light disinfection to ensure that the UV-C light is being used appropriately and safely.

Recent Creative Ideas for UV-C light usage in households: 

1. Self-cleaning toilets that use UV-C light (whenever you do not use it, that is): 

2. Water bottles with UV-C light to make sure you are not drinking some nasty bacteria. 

3. UV-C light in robotic vacuum cleaners, so your floor is being cleaned and disinfected at the same time. this can be useful, especially when mopping vacuum cleaners cannot use any chemicals. 

4. UV-C to clean tooth-brushes

5. UV-C for smartphone & other small items santisation 

+ Two new bonus ideas for UV-C light in the household & public spaces:

1. Automated night light that is light sensitive
As the UV-C light is not the nicest for your beautiful skin, it should turn on only during the night (imagine someone is working on removing mould and nasty bacteria from your bathroom while you are sleeping). What's more, it should only turn on when the bathroom light is off. The moment the bathroom light is on or the door opens with external light coming in, a photo-sensitive switch would the blue light off. 

2. Public bathroom (and showers) light 
The idea is very similar, the UV-C light goes on plus the public bathrooms use also a quick round of steam with a fan to ensure every little piece of nasty is gone. 

3. Wardrobe with UV-C light
In this case, the light would only be on during the night & when the wardrobe is closed. The moment it opens, the light switches off. The idea is to have this sold separately so one can install it in any drawer, closet, wardrobe or kitchen cabinet as needed. This system would be handy in greatly humid countries, where one's clothes mould easily in wardrobes. It could also prolong the time until the laundry is needed.
