Dustless Technologies D1606 True HEPA Shop Vacuum - Wet/Dry Commercial Vacuum Cleaner for Contractors & Professionals | Home & Workshop Use

I purchased this to clean up after asbestos was found in my house. I learned that conventional wet / dry vacuums, and household vacuums are NOT capable of safely cleaning up fine particles like lead and asbestos, even if they mention HEPA. This is not a typical wet / dry vacuum, it actually comes with a certificate indicating its level of filtration and performance. The vacuum is well designed, and the price is reasonable.The only design weakness I've noticed so far is the little yellow clips that secure the motor into the lid, and the lid onto the canister; they actually send an extra, as if it's assumed you're going to break one at some point. I'm fairly careful with equipment, so don't really expect this to be an issue.Like any powerful vacuum, it does discharge a lot of air. I mention this because the exhaust will move dust around the room, so you'll still need to ventilate accordingly and wear the proper high filtration respirator if hazardous substances are present. I ordered the 25ft extension hose to reduce this issue by setting the vacuum away from the work area.The vacuum uses three filters: A bag filter, a filtering cover that goes over the final filter, and a certified HEPA final filter. Replacing the final filter will be expensive (around $150) but the manufacturer says you won't have to change it often if you use the filter bags (around $13ea) which hold up to 40lbs of stuff. The machine and filter costs are higher than regular wet /dry vacuums, but not as costly as potential health issues or hiring someone to clean up.I am satisfied with this purchase, and would recommend to a friend.
