I use ozone quite often in the rentals I clean for cigarette,reefer and curry. Those Maxblasters looked good for the money but I never knew anyone who had one and I've known alot of people who had constant problems with their machines breaking.
The 3 brands I see often are Bridgepoint,Sonozaire and Totalzone. My distributor carried all three and now only sells Totalzone. He and several restorers said they were far
superior in durability. I've used mine dozens of times with no problems.
I fpound the treatment times to need much longer than claimed. Bought a 2nd (both TZ2) and usually treat a 2000 ft home for 72 hrs.
Many people are loving the new Hydroxyl generators which work the same as ozone but are safe in occuppied areas. They are also made by Totalzone. I might get one but dollar for dollar on the investment they claim to treat a lot smaller area.
