Unfortunately it’s not one with an easy answer. Life of each filter is greatly dependent on your application(s), materials being processed and hours of daily use. 

Heavy wood processing (cutting or engraving) will have a greater impact on the pre-filter life. Due to the sticky residue / particles from wood processing, the pre-filter tends to get saturated quicker whereas the oxy-carbon may last 2 years. 

No. Filtrabox pre-filters and HEPA filters are designed to maximize capture efficiency for ultrafine laser particulates. Compressed air, cleaning agents or other cleaning methods may result in a damaged or inefficient filtration. Our oxy-carbon filters contain a mixture of coconut shell activated carbon and potassium permanganate The adsorption and chemical reactions that take place between the contaminants and the media are not reversible.

It starts with reading through our short but complete owner’s manual. If you don’t have a copy, you can download the latest version here. Our 3-steps to maximize filter life document, found here is also recommended. The owner's manual will get you familiar with your specific Filtrabox model, filter location and provide instructions on how to check a few things.

What isn’t noted in the owner's manual is that the Filtrabox air-flow range and filter life remaining feature operates on a scale of 1-100%. If your air-flow setting is set to 40% and if you do a filter check test, you’ll get roughly 60% life remaining, even with brand new filters installed. If the air-flow is set to 60%, filter life remaining will be approximately 40%, even with new filters installed. 

The filter check feature is very useful in gauging how much life you have remaining in your filters before replacements are required.
