24″ x 24″ x 4″ High Capacity Wire Backed Pleated Pre Filter (6 Pack)
Total Filtration Services Filters Pleated Air Filter MERV 8 Low Initial Resistance for Energy Savings Quality Engineered Pack of 6 Filters Used filters must be disposed of properly, since they may be classified as a hazardous waste. The federal law that covers disposal of waste is the Resource Conservation and Recovery Act (RCRA).
Lead captured by the filter may be recycled. Recycling activities are exempt from RCRA regulations. If you do not recycle the lead in the filters, the filters should be tested using the Toxicity Characteristic Leaching Procedure (TCLP). If the TCLP results are less than 5 parts per million (ppm), the filters can be disposed of as normal solid waste (trash).
If the TCLP results are above 5 ppm, the filter must be disposed of as hazardous waste through a licensed hazardous waste company. You should keep all test results and shipping manifests in a file so you can demonstrate that the waste has been disposed of properly.
