Laguna Pro X Spray booth requires 1 set of 2 filters. The aluminum holds up much better then the styrofoam.
Laguna Clay Company offers two types of filters for the Pro-V or Pro X Spray
Booth, styrofoam filters or long-lasting aluminum filters. Both filters are baffle design and should be washed after each spraying session. A set of two filters is required for the Pro V booth, and one filter for the Pro X. Some filters are not reversible and must be positioned as indicated by air-flow arrows on the side of the filters.
