Description Part No: IFA3PT – Filter Kit for BV500 Mist Extractors – pack of 3 Set of 3 tanning mist replacement filters for BV500 (S500) tanning units. What’s in the pack: 3x IFA3 particle/solution filters 3x PRE495 pad filters These are high volume replacement filters, with each filter gives up to 70 Tans. The SolarEx filters use high volume spray capture media to ensure all the overspray is contained within the filter. No messy filters to clean each night We do not use washable filters as we feel that they are not suitable for grease based products.  By virtue that tanning solution is a liquid, then the efficiency of a filter that can be cleaned in a liquid is limited.
