The Covid-19 pandemic has made many of us a lot more wary of viruses and bacteria – not just the novel coronavirus.

Sales of portable UV light sterilizers have skyrocketed in recent months, with hundreds of thousands of people across the world looking to these relatively new devices to keep their homes and cars germ-free and safe.

What is UV Light?
Ultraviolet light is a type of electromagnetic radiation. UV-C light (the radiation emitted from such sterilizer wands) is essentially UV light and has a wavelength of 200 to 280 nanometers.
What is a Portable UV Light Sterilizer?
A portable UV light sterilizer is a small device that emits UV light (of a specific wavelength) to kill germs and disinfectant surfaces. They can be great for disinfecting toilets, phones, laptops, parts of your home and car, plus much more.
The ultraviolet light – specifically, UV-C light – these devices emit is the same kind of UV light that causes sunburn and can also lead to skin cancer. So it’s imperative to follow the instructions the manufacturer provides so you can safely use your UV light sterilizer.
Ultraviolet germicidal irradiation (UVGI) is one of the most effective ways to kill germs, according to numerous scientific studies, so it’s not surprising that the popularity of devices that use such technology has spiked in recent months.
How Do You Use a UV Light Sterilizer?
Different UV light sterilizing devices are used in different ways, so you should make sure you read the instruction manual before trying out the device.
As a general rule, you need to leave the room as soon as turning a UV lamp on – and research suggests that germs need to be exposed to UV-C light for about 30 minutes to be extinguished.
As for other UV sterilizers, such as wands, you simply need to press down the activation button and hold the wand over a surface for a matter of seconds.
There are also UV sterilizer boxes, in which you place a device you’d like to disinfect and leave it for the specified period of time (usually around 20-30 minutes.)
How Much Do UV Light Sterilizers Cost?
UV light sterilizers cost anywhere from $30 to over $200 depending on the exact type you’re looking to buy. It is possible to purchase an unbranded one for even less than $30. Still, we strongly advise against purchasing such products, as they may be defective or not manufactured and tested to the required safety standards.
Do Portable UV Light Sterilizers Kill 100% of Germs?
UV light wands kill germs, such as harmful bacteria and viruses, by destroying the bonds between their DNA, causing them to disintegrate and die.
As with other disinfecting tools and mechanisms, portable UV light sterilizers don’t kill 100 percent of germs; they kill around 99.9 percent of bacteria and viruses on a surface after the germs are exposed to the UV-C light rays for a certain period of time.
Despite not killing 100% of germs, they are still highly effective and have long been used by hospitals to disinfect surfaces thoroughly.
Are UV Light Sterilizers Safe?
UV light wands are safe to use as long as you carefully read and follow the instructions the manufacturer has provided.
If you are exposed to UV-C light rays, you are putting your health at risk, so we urge everyone – boomers and other users – to be very careful when using a UV light sterilizer.
Most UV light sterilizers have auto-off features to prevent the user from being exposed to the harmful radiation, but it’s still important to be as careful as possible.
How Can I Find a Trusted Manufacturer or Seller?
All of the products listed in our Top Picks section towards the top of this guide are sold and manufactured by trusted, established brands, so you should certainly give our Top Picks some consideration.
When evaluating whether or not a manufacturer or seller is trustworthy, you should check how long they’ve been in business. If they popped up during the Covid-19 pandemic (and were therefore seemingly launched to quickly profit from the increased demand of such devices), it’s probably best to exercise caution and steer clear of them.
Look for certified by FCC or CE. This shows the item has been cleared for sale in the U.S. and EU.
Another red flag is retailers aggressively promoting their product on their listing or landing page and making use of things such as countdown timers or trying to emphasize scarcity in other ways.
A UV light sterilizer can be effective to thoroughly disinfect your house and devices which harbor thousands of different types of germs – regardless of whether or not we’re amid a pandemic.
They should always be operated with the utmost care, and you should always read the manufacturer’s instructions manual before trying to use it.
Due to recent health issues including Covid-19, numerous companies have cropped up trying to profit from the pandemic by selling low-quality in-demand products, such as UV light wands and face masks, at huge margins. It is therefore strongly advised to stay away from new, unestablished brands of such products. Instead, stick to established manufacturers whose products have been tested and reviewed by a third party.
