A HEPA vacuum is a vacuum cleaner with a High Efficiency Particulate Air (HEPA) filter as the last filtration stage. This filter captures very small particles, including asbestos fibers. The vacuum is built with seals to ensure all intake air goes through the filter, stopping fine particles from being released back into the air. HEPA vacuums must be used and maintained according to the manufacturer's instructions.
Under §296.21(45) of the Texas Asbestos Health Protection Rules (TAHPR), “HEPA” is defined as a high-efficiency particulate air filtration, capable of trapping and retaining 99.97% of mono-dispersed airborne particles that are 0.3 micron or larger in diameter.
Yes. Under §296.212 of the Texas Asbestos Health Protection Rules (TAHPR), asbestos abatement activities are required to be performed using work practices that prevent the release of asbestos fibers in public buildings. This includes the use of HEPA-filtered equipment for cleanup and dust control.
Household or shop vacuums not built for proper HEPA filtration are not suitable for asbestos cleanup in public buildings. Just adding a HEPA filter to a standard household or shop vacuum may not be acceptable. A vacuum modified with a HEPA filter may have issues with its seal or design, which means it will not filter all air through the HEPA filter. This makes it unsuitable for asbestos cleanup in public buildings. Asbestos abatement companies should use vacuums specifically designed for HEPA filters.
Equipment used during asbestos work must follow the Texas Asbestos Health Protection Rules (TAHPR) work practices. This helps prevent the release of asbestos fibers.
Yes, disposable HEPA filters may be acceptable if they meet all the following requirements:
The filter meets the HEPA definition under §296.21(45) of the Texas Asbestos Health Protection Rules (TAHPR).
The filter is used according to the manufacturer’s instructions.
The filter is used following all applicable asbestos work practices.
After use, the filter is disposed of as asbestos waste.
