Hey yea, thats a nice kit there.realy nice, i have been looking for one like that.Do you know a price?

but look at what crag6928 said. It is possible to build a box like that at a fraction of the price.And you can get 3 stage filters that filter a 15m2 per hour for something stupid like £20. It does need
strong DIY skills though because that of the way the air needs to processed. That box you linked to uses double cycle air filtration and compression.
--
1 cycle (hepa+ioniser) cleaning process where it ionises the intake and pressurises the air
*in between i suspect there is like a inverted tube or spiral where the ionised air passes and all the ionised particles get refiltered or wasted
2 HEPA to remove another 99.9% of particles from the already 99.9% filtered air and some sort of sponge to distribute the air in a uniform and calm way downwards and out- preventing particles from entering where you put your hands.

But you dont need to build a double cycle like this.
More ideal would be to build a larger closed box like comparment with sealed gloves. build it in such a way that the air inside recylces at 15-20 times per hour. Then we are talking about some pretty darn clean air even if small containments are introduced via device or anything else. You would need positive pressure here to just in case there are leaks. but its not critical.
I am planning to do a project like this next year and test it out. I shall be posting tutorials and outcomes of how good it is. Many people think im stupid- but i just like exploring.
