Question: There is a powder discharge when I hook my filter up to a fan. Is this normal?

Answer: Yes, due to the fineness of our filtration medium, some loose particles may be discharged when hooked up to a fan initially. This should go away after 15 seconds. The particles are chemically harmless but avoid inhalation due to the potential for irritation.
