Fiberglass insulation holds up quite well to UV-C. The UV-C will not affect the “glass” component in the insulation, it can affect the binders in the insulation, but overall we tend to not worry about insulation if it is glass based. Same think can be said for filters, i.e. synthetic filters will get eaten up by the UV-C, but glass-based filters (e.g. HEPA) hold up to UV-C.
Thank you for your question. We will add this to our FAQ’s for other consumers.
If it is mounted in the return duct, how far from the filter should it be placed? Do you only need to avoid light from the bulb hitting the filter directly or is it more based on distance? I use a large 6+ month pleated filter.
When installing your UV-Sanitizer we ask that the bulb be placed 20″ away from any filter system. This will assist in preventing direct UV damage to your filter.
Will the UV-C light degrade fiberglass insulation inside the AC duct housing next to the coils?

Where is the best location for the light on an N shaped AC coil?
