Since I have put my XJ 2000 ionic air purifier in I have noticed an absense of dust on all of the CRT monitors, and surface dust on the console. A few years ago when we had the fires here in So Cal. is when I got these machines. Outside there was ash all over the ground. For about 2 weeks, I had to clean the plates on the purifier every day in the studio. It was after that, that a client with cat alergies asked if I got rid of the cats. The cats have never been in the studio, but previously, it still used to affect him. Since getting these machines everything is fine.
As far as cats on the console? Highly not recommended. Cat hair and dander getting into the faders and pots will eventually result
