The colored air entry surface indicates the use of the filter. The surface in the entry direction of air is colored green, yellow and pink. The paint holder-green filter binds the waste paint particles to itself and in this way prevents the discharge of paint into the environment. The dust collector-yellow filter is coated with an antibacterial, adhesive binder to bind dry powder types. The main usage area of the pink filter is water-based painting. Due to the increasingly frequent texture towards the depth, it is used not only for the surface of the material but also for holding the whole depth of paint and dust.
