For collision repair centers and industrial manufacturers who own a paint booth, one of the easiest ways to protect the environment is to properly dispose of paint booth exhaust filters.
Since most paint that is sprayed contains hazardous compounds and is potentially flammable, extra care must be taken when it is time to dispose of your paint booth filters. At this time, it is not possible to recycle paint booth filters. Proper paint booth filter disposal not only ensures your business is following the law, but it is also what is best for the environment.
Here are five steps for proper paint booth filter disposal:
1. Determine If Your Used Paint Booth Filters Are Hazardous
Before disposing of your paint booth exhaust filters as general waste, you need to verify your filters have not been exposed to any of the hazardous compounds that are frequently found in paint. You must perform a Toxicity Characteristic Leaching Procedure (TCLP) laboratory test to determine if the paint you sprayed contains specific compounds. Your filters are considered hazardous if a certain amount of any of the following compounds are present in your filters:
Paint booth intake filters are designed to remove dust and other small airborne particles to supply a contaminant-free environment for painting. As long as the intake filters have not come in contact with paint, they are not hazardous. This means the intake filters can be disposed of in your normal trash.
2. Properly Dispose of Hazardous Paint Booth Exhaust Filters
If your paint booth exhaust filters are deemed hazardous, they should not be disposed of as standard waste. Instead, they must be properly stored and sent to a hazardous waste disposal facility. Store them in a non-leaking container marked with the words “hazardous waste” and a description of the waste, such as “waste paint booth filters.” Then, use a licensed hazardous waste transporter to ship the container to a hazardous waste disposal facility.
Before disposing of hazardous paint booth exhaust filters, you should always let them dry. Allowing your paint booth exhaust filters to dry typically eliminates the chance of ignitability. It is safest to subject the filters to the same curing process you use for painted products to accelerate drying of the filters and ensure they are completely dry before disposal.
3. Contact Trash Collector Before Disposing of Non-Hazardous Paint Booth Filters
Even if your paint booth exhaust filters are not deemed hazardous waste, you should notify your trash company that you are disposing of the filters as standard waste. Your trash collector may ask you to provide proof that no hazardous compounds are present in the filters. Make sure to retain documentation of the safety data sheets (SDS) of the materials you are spraying, lab test results and any other pertinent information your state recommends you keep on file.
4. Do Not Spray Gun Cleaners Into Paint Booth Exhaust Filters
Many spray gun and wand cleaners contain solvents that are classified as F-listed hazardous waste, including methylene chloride, methyl ethyl ketone (MEK) and toluene. This is indicated on the SDS of the solvent as F001, F002, F004 or F005.
Spraying solvents into the exhaust filters during gun cleaning can cause your filters to be considered hazardous waste. When cleaning your spray gun, make sure to keep solvents away from the paint booth filters. It is best to spray solvents into closable hazardous waste collection containers or use a gun washing system.
5. Test Filters Whenever You Make a Change to Your Paint Process
Determining whether your paint booth exhaust filters are hazardous waste can be an ongoing process, depending on how often you introduce new paint into your operation. Testing is required whenever parts of your painting process change.
Any time you add a new paint, you need to evaluate the paint to see if it contains hazardous compounds. Since testing can take some time, you should give yourself a buffer before you intend to spray the paint.
Regulations regarding paint booth filter disposal vary from state to state and sometimes even from county to county; your local authorities can tell you the requirements for your area. Since you cannot recycle paint booth filters, considering them hazardous waste and coordinating with a hazardous waste disposal company to dispose of them properly is the safest thing for the environment.

Compressed air is readily available and simple-to-use, but it can be the most expensive form of energy in your application. Air leaving a compressor can also be dirty, and depending on the outside temperature, can contain moisture. The presence of moisture in the air line can damage and shorten the life of downstream equipment, such as pneumatic tools and Liquid/Powder spray equipment. Unregulated or improper air pressure can result in increased compressed air demand, which results in increased energy consumption. Excessive pressure can also increase equipment wear, resulting in higher maintenance costs and shorter tool life. Before compressed air can be used it should be Filtered, Regulated and in some applications, Lubricated.
Filters clean compressed air. Compressed air can carry condensed water, oil carryover from compressors, solid impurities (dirt and rust) generated within the pipelines, and other wear particles from the ambient air. These contaminants can cause problems at every point of use, and should be removed by installing suitable filters.
Regulators reduce and control pressure in compressed air systems. They are used to control pressure to: air tools, such as impact wrenches and sanders, liquid and powder spraying devices and many other pneumatically powered manufacturing applications. Optimally, a pressure regulator maintains a constant output pressure regardless of variations in the input pressure and downstream flow requirements. Downstream equipment flow and pressure requirements must be determined to properly size the correct regulator for the application.
Lubricators add controlled quantities of oil into a compressed air system to reduce the friction of moving components. Most air tools and other air driven equipment require lubrication to extend their useful life. The use of an airline lubricator solves the problem of too much or too little lubrication that comes with other methods of lubrication such as a grease gun or oil, as well as supplying the right kind of lubricant for the tools being used. Once the lubricator is adjusted, a metered quantity of lubricant is supplied to the air operated equipment and the only maintenance required is a periodic refill of the lubricator reservoir. Adding lubrication to a system can also prevent synthetic compressor oil build-up on system components.
Clean air is a key ingredient that enables effective and efficient operation of tools, equipment, and machinery in almost every industry. As such, the use of air preparation devices, such as filters, regulators, and lubricators (FRLs) is an excellent way to keep your air supply in top condition, as well as enabling your tools and equipment to operate at their peak performance. Air Power can help you identify the cause of your airline issues and find a solution to keep your airlines clean and controlled.
