If the source of asbestos contamination is still within the home, a HEPA filter will not be able to remove all particles over 0.3 microns in size. Professional asbestos removal must be done by a professional, then any remaining asbestos particles must be removed by a HEPA filter. It is not advisable to try to discard asbestos-contaminated material on your own, since any movement or jostling will release the particles into the air you breathe. You should not attempt to handle asbestos on your own, according to Occupational Health and Safety codes in Alberta. If you are working in an area with asbestos, you have to complete a training program before handling the material.
When you are concerned about asbestos in your home, you should stay away from the area, do not disturb it, and contact a professional asbestos worker to remove it. An asbestos HEPA air purifier will be able to remove any remaining particles during and after the process.
