Do You Need an Air Filtration System for Laser-Cutter Technology?

As a seasoned laser-machine user, you might be used to the smoke and odors that roil off the workstation during usage. If you’ve just purchased a laser machine, you might wonder if you truly need an air filtration system for laser-cutter devices in your home.

An air filter’s function is to eliminate fumes and particulate matter in the air, creating a safe environment for nearby workers. Whether these fumes are produced by a laser machine or some other unit, an air filtration system can easily turn toxic clouds into breathable air.

If you have a laser machine with built-in air ventilation, you most likely don’t need an additional air ventilation system. For example, the OMTech Polar is an all-inclusive, desktop laser machine that comes with an inline duct fan and duct tubes for ventilation.

The safety and comfort of our customers are paramount, so ensure you are utilizing your laser machine with an air filtration system. Whether this looks like purchasing a unit with ventilation or acquiring an air filter accessory, the only thing that matters is having a safe working environment.

Why Is It Important to Have a Filter When Using a Laser Cutter?

Having a filter when using a laser cutter/engraver is important for maintaining a safe and breathable environment while working. Just as you might need eye protection from the intense laser beam, it is also essential to protect your lungs from the fumes and particulates produced by the laser machine.

Cutting materials like PVC, artificial leather, and other materials can produce, at best, unpleasant odors, or; at worst, hazardous fumes that detriment your health.

For home users, you might be utilizing your laser machine wherever you have room; whether it’s a garage, bedroom, or storage space, having ventilation is essential. If you are unable to ventilate the fumes from your laser machine to the outdoors via an open window or exhaust fan, utilizing air filtration for laser engraving is paramount for maintaining your physical well-being.
