This kit includes replacements for all four types of filters for the Beam Air Fume Extractor:

• Pre-Filter: This is the first layer of defense! The pre-filter is positioned on the top of the Beam Air, so it is the first filter that will be preventing particles from passing through – coming from the laser cutter which is connected via a tube. Because this filter is the thinnest and the top layer, this filter will need to be replaced after every 10 – 30 hours of use.
• Medium Efficiency Filter: Just below the pre-filter, the medium efficiency filter provides a buffer and further filtering out particles which managed to get through the pre-filter. To ensure the Beam Air is eliminating as many particles from passing to the outside environment, this filter will need to be replaced after every 50 – 150 hours of use.
• H13 HEPA Filter: The third section of the Beam Air is known as the H13 HEPA Filter and as it is near the center of the Beam Air, it filters out the few remaining particles that may have penetrated past the other two filters. This filter will need to be replaced after every 100 – 200 hours of use.
• Activated Charcoal Filter: This is the bottom filter, or final filter, of the Beam Air. Particles have to make it past three other filters to reach this one. This filter can eliminate almost all of the particles at this point, allowing for the Beam Air to be a proficient fume extractor. This long-lasting filter will need to be replaced after every 300 – 600 hours of use.

Please note that filters are not returnable after having been opened. If there is a problem with the packaging or damage during shipment, please refuse package or contact our team immediately for RMA procedures.
