We want you to understand what our UV technology and device are all about. If you have any questions, search for them below. In case you cannot find your answers here, please get in touch and we will be happy to help you out.

As of now, the straps are not replaceable. However, they are made of high-quality thermoplastic rubber and are expected to last for the lifetime of the product.

No, currently the batteries are integrated and not replaceable. Please do not attempt to separate the batteries from the casing or replace them.

Yes, the device can be used while charging when using a compatible 18W fast charger. See the Charging section of the user manual for more information.

Yes! The filter can simply be cleaned from the outside by using a vacuum cleaner or be rinsed under a running faucet and air-dried. We recommend cleaning it once a month.

The filters are replaceable and can be bought from our website. To replace the filter, follow the steps outlined in the maintenance section of the user guide. This should be done around once a year.

Our device comes in one-size-fits-all with adjustable straps. It is designed to be comfortable to wear for most people over the age of 12.

Yes, the device has a built-in filter to keep dust and larger particles away from the disinfection module.

The device can be cleaned using a soft, damp cloth. Medical alcohol may also be used to disinfect the surface of the device. Make sure to turn off the device before cleaning it and be careful not to get water inside the product.

The device should be stored at room temperature, low humidity, and away from direct sunlight.

It uses UV-C light to inactivate airborne pathogens (viruses, bacteria, fungi, etc.)! UV-C is a specific range of invisible light that has been known to have disinfectant properties for decades. UV-C radiation destroys the genetic material of the pathogens to the point where they are unable to reproduce or multiply.

The UV-C LEDs in our device are expected to last for around 3.5 years with frequent use.

The device takes around 4 hours to fully charge when using a 18W fast charger. To preserve the batteries, we recommend charging the device for 8 hours before initial use.

The battery lasts for around 8 hours with normal usage.

At maximum speed, the device purifies 55 litres of air per minute, which is around 4 times more than an average resting person breathes.

Running at the lower speed, our device produces around 43 dB of noise, which is around as loud as light rain or a quiet office setting.

Not at all! As our device supplies sterilised air to the space in front of your face, it does not restrict breathing or restrict the visibility of your face in any way.

The Respiray wearable air purifier has passed successful tests with alphavirus, that is a similar single-stranded RNA-genome virus to SARS-CoV-2 and both viruses are comparable in size: approximately 70-100 nanometers. There are many studies that show how coronavirus acts similar to other viruses and bacteria that UV-C light successfully inactivates.

A large amount of research has shown that UV-C is extremely effective since it inactivates pathogens in different ways. For example, for all known coronaviruses it has been shown that UV-C breaks the RNA chains rendering the virus unable to reproduce. It also disintegrates the membrane of the coronavirus virion and on top of it all breaks the structure of the famous spike proteins of the coronavirus. UV-C LED manufacturer Crystal IS, whose LEDs our device uses, presents research that demonstrates the effectiveness of germicidal UVC LEDs against SARS-CoV-2.

Another UV-C LED manufacturer has run tests comparing necessary light intensities to inactivate 99.9% pathogens and found that a similar UV-C light dose was needed to inactivate both E. Coli bacteria and SARS-CoV-2 at 265 nm. Further tests have also shown that UV-C light is effective at inactivating SARS-CoV-2 (COVID-19).

The effectiveness of our disinfection module has been independently tested for S. aureus and E. coli bacteria, resulting in around 2.5 and 2.6 log reduction respectively (99.68% and 99.89%) at 30 l/min throughputs. Our device has two of these disinfection modules built-in.

Please note: Respiray’s air purifier is not medical-grade Personal Protective Equipment (PPE), and in circumstances where medical-grade Personal Protective Equipment is recommended, you should consult a health care professional. Please remember that the use of our wearable air purifier does not replace the recommended measures to stop the spread of COVID-19. Follow the latest guidelines and rules of your local authorities and health care professionals.

Due to the size of the device and the inherent risk of UV-C light and batteries, the device is not meant to be used by children under the age of 12.

Our device is not water-resistant and is not meant to be used in humid or wet environments.

We recommend wearing the device with the face shield in most situations, as the shield provides direct protection against coughs and sneezes. In lower-risk and stationary situations, such as sitting alone at an office desk, the face shield might not be necessary.

Direct exposure to UV-C light is dangerous to humans. However, in our device, the UV-C light is completely sealed inside the device, so no UV-C light is exposed to humans. We have very serious protective measures in place to ensure the safety of our device including a double UV-C resistant plastic enclosure around the UV-C emitting LED. We have conducted various tests including drop tests to ensure the design is robust and does not break easily.

Our parent company AS LDiamon has over a decade of experience with optics and UV-C, and also meets the standards for an ISO 13485:2016 certificate, meaning they are internationally certified to manufacture and handle medical devices. Additionally, we have added numerous protective measures to ensure the safety of our device.

Absolutely not. While at some wavelengths the energy of UV light is able to produce ozone, this only happens at below 242 nm (Scientific Committee on Health, Environmental and Emerging Risks). The LEDs in our device emit a very narrow range of UV-C light at 265 nm, which will produce no ozone, atomic oxygen or any dangerous radicals. Furthermore, at wavelengths of 242-315 nm, ozone is broken back into oxygen molecules instead, reducing the ambient ozone in the air. We have also thoroughly measured our device with ozone meters to ensure that there are no ozone emissions.

For additional safety, we have carried out ozone tests with a laboratory affiliated with Tartu University and the results showed no indication of ozone production.

Our device is a wearable UV air purifier that creates a clean air zone around the wearer’s face without covering their face or restricting their breathing.

The casing is made out of high-quality PC/ABS plastic.

It has a USB Type-C charging port.

Most cars are airbag-equipped vehicles. Should a traffic accident occur, the airbag will launch, which could potentially cause further injury to the wearer.

At the moment our device is currently available in Dark Grey and White, but we are considering adding more options in the future!
