Exposure to laser treatment involves a mixture of biological, cellular particles, which may also be gaseous or vaporous. In addition to papillomaviruses and multidrug-resistant pathogens, researchers have detected benzene, toluene and xylene, hydrogen cyanide (hydrocyanic acid), formaldehyde, acetaldehyde, acrolein, cresols, and phenol in laser smoke. Depending on the energy exposure, the particles can be larger than 200 microns or smaller than 10 nanometers. When the coolant sprayed on the skin during laser hair removal burns, highly toxic vapors are produced. The patented InLine filter, a pre-filter in the capture element, provides a high level of protection against these dangerous particles.
To minimize risk, thermal vaporization techniques, such as Nd:YAG laser, should be preferred for such treatments. Plastics used in the treatment may be flammable. PVC produces hazardous gases such as HCI. If these gases come into contact with mucous membranes, the hydrochloric acid produced can cause tissue burns and, if inhaled, collapse of the alveoli. Technical protective measures such as standard laser equipment, correct extraction of combustion products, use of activated carbon or HEPA filters, and safe handling of chemicals, are essential to protect personnel and ensure safety.
The InLine filter is placed in the extraction hood. Therefore, it catches most airborne particles directly before they can even enter the extraction arm and the filter system. This extends the service life of its main filters, as they have to be changed less frequently than without the InLine filter. In addition, the cleaning time of the system’s extraction arms is reduced as well.
Only effective collection and filtration in combination with cleaning and disinfection of surfaces protects against the spread of viruses/bacteria between patients. Keeping the system on between treatments allows it to filter all the air in the treatment room several times an hour, significantly reducing the risk of contamination and infection.
To comply with the TBH hygiene concept, we recommend:
- InLine filter 1x daily
- Change the HEPA-main filter in the system only every six months
