How to Maintain a Fume Extractor for Your Laser Engraver
Keeping the air clean in your workshop isn’t just good practice — it’s essential when you’re running a laser engraver. A fume extractor plays a huge role in protecting your health, improving engraving quality, and keeping your workspace compliant with safe-use standards. With a little regular care, your fume extractor can run smoothly for years while saving you money on unnecessary repairs. In this guide, you’ll find a simple guide to understanding when your fume extractor needs attention and how to keep it performing at its best.

Signs Your Fume Extractor Needs Maintenance
Even the best fume extractors need occasional upkeep. Here are some common signs that it’s time to give yours a check:
- Reduced suction or weaker airflow — your extractor isn’t moving air as efficiently as before.
- Visible smoke in the laser bed — smoke should be pulled away quickly; lingering smoke indicates a blockage or full filter.
- Stronger odours during engraving — especially when cutting wood, acrylic, or leather.
- Increased noise or unusual vibration — often caused by clogged filters or airflow restriction.
- Dirty or discoloured filters — a clear sign that replacement is overdue.
If you notice one or more of these, a quick maintenance session will usually restore proper performance.
General Maintenance
To keep your fume extractor running efficiently, it’s helpful to follow a simple routine. Most manufacturers provide recommended maintenance intervals, and your user manual will outline the exact steps for your model.
For example, general maintenance for the OMTech 150W fume extractor typically includes:
- Always turn off and unplug the device before cleaning or maintenance. For best results, turn off and unplug the device between uses.
- Clean the device’s exterior and hoses as needed, using a soft cloth. Never allow water to make contact with electronic components. Never use caustic solvents or harsh abrasives.
- Replace the filter elements regularly. (See below for details.) Check the filter elements at other times if you notice the device’s suction is becoming weak. Do not attempt to continue use with clogged filters.
- Remove and replace the filters carefully, noting their order and direction.
- Mark the specific replacement date on new filters during replacement.

How to Replace the Filters Properly
Filter replacements are the most important part of fume extractor care. The user manual for your machine will specify the correct replacement method.
For the OMTech 150W fume extractor, you can follow the steps below:
Note: ALWAYS use PPE, including a N100 respirator, goggles, and nitrile or latex gloves before replacing the filter.
1. Remove the top cover by unlatching the cover on both sides and lifting it.
2. Hold the structured borders with both hands and carefully remove the used filter cartridge.
3. Install a new filter cartridge into the machine carefully.
4. Place the top cover back on and close the cover latches.
