I just picked one of these up. There is very little written on these units so I thought I would write a short blurb. I looked for a long time at Jet and this unit. The jet had very high reviews so I was on the fence
The SuperMax Tool unit, in my opinion seemed looked like a great deal of care was taken on appearance and finish. I decided to go for this unit. It came packed in a fully enclosed styrofoam clamshell in the case. To further unpack it, the two filters are removed to remove the additional styrofoam blocks on the top and bottom of the motor and fan unit. This air cleaner is very quiet right out of the box in my subjective opinion. I can't judge cleaning but very impressed with fit and finish, as well as noise levels compared to other models I looked at. It is at ground level now, will be ceiling mounted tomorrow. Any issues with mounting I will update this post.
There is not much to write about these units when they run like they are supposed to out of the box. Hope this is helpful to anyone considering it.
