How to Properly Dispose of Paint Booth Exhaust Filters to Protect the Environment
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.

Filter Conversion to Eliminate Overspray
Overspray in industrial finishing applications is one of the most common causes of parts being rejected by quality control inspections. This can result in constant costly reworks and low-quality finish on parts. In this case study, Air Power proposes a solution that completely eliminates overspray for this customer.
Manufacturer of plumbing and water-related fittings and valves
This customer was experiencing paint buildup on their booth due to overspray. This was caused by inefficient airflow through the booth. This customer was using an old baffle style booth that uses offset layers of metal to catch the initial overspray and then redirects the overspray into the second layer of filters. As a second layer of filtration, the customer used Styrofoam baffle filters that allowed a high volume of bypass of a mixture of tacky and dry overspray. This type of baffle filter works better with wet paint overspray.
Without proper airflow collecting the overspray in the booth, this customer experienced a higher number of rejected parts, a lower quality finish on products, and paint buildup on their spray booth and surrounding areas.
Air Power Solution
Air Power proposed a solution that updated the filtration system to a more efficient style. This solution included completely removing the metal vertical baffles that were the first stage of filtration. The second stage Styrofoam baffle filters were then removed and the 20×20 grid was scraped clean of all the overspray buildup. Then we installed Kem-Wove P3 20×20 panel filters in the second stage, installed snapper bars on the front of the filter wall, and added RP 3252 paper/poly blankets (RTT Engineered Solutions / Col-Met) as the first stage of filtration to improve overspray capture and airflow.
This customer was amazed by the change in airflow and overspray capture in their spray booth. This new filtration system collected all the overspray in the booth and allowed nothing to bypass for the first time. These changes improved the painting conditions for operators in the booth, allowing for a higher quality finish on products. This customer is currently in the testing stage with this system to determine the length of life for one layer of filtration to ensure this system is cost-efficient and establish best practices for their finishing operation.
