I bought a Brookstone Pure-Ion UV about 7 months ago that was working wonderfully night and day. Recently I noticed that there is no dirt collecting on the cylinders. I pulled them out and vacuumed/wiped off a lot of dirt that was inside the unit. I paid careful attention to the contacts at the bottom that supply the voltage to the cylinders. I've run it overnight and still there is no dust/dirt stuck to the cylinders. The fan runs, the UV lights, and it sounds the same. What else can I try? I have a multimeter. Are there ways to can check voltages, shorts, or opens?
I bought one a year ago and never thought it work well in cleaning the air. I get more dust on my counters than collects in the pure-ion. I recently got a letter from an attorney saying they are settling a class action suit on these purifiers because the are not effective. I called brookstone and they said they will refund my money because of the law suit. Good luck.

We had a problem with ours, it kept telling us the filter needed cleaning, though it had just been done and was actually fine. It would sound a high pitched alarm and "freak out" on us.
We found using a shop vac and cleaning it out all (while unplugged, of course) inside where there are intakes and general insides was greatly helpful. It was making a crackling noise as well, quite often.
We have asthma and allergies in the household and rely on this to help our family, it's a wonderful thing to own, we love it.
But, this one problem had us stumped. Do try to use a powerful vacuum and really get inside. We have cats and apparently cat hair as well as household dust was clogging it. You obviously need to do more than clean the filters, themselves, from time to time.
I just got one from some one that wash trashing it because it quit. The problem with this one was a bad power regulating transistor. $1.69 at Radio Shack. I also found that the board that supplies the voltage to the grid had several bad solder joints on it. Take the bottom/stand off: four screws. Take the next 4 screws you see out then the bottom should come off. The small board next to the motor energizes the grids. The transistor on that board needed to be re solderd. Also the flimsy black wire was loose too. Hope this helps.
