these particulate filters catch all the small paint particles that you would other be dealing with on your vapor filters, they'll save you from buying more vapor filters so you save money in the long run, keep in mind though good ventilation is a must have when spraying automotive paint, you can quickly clog these filters up while spraying.
excellent value, good particulate filters excellent service also.
