TOTALLY OFF THE SUBJECT WOODBURNER, but..... it sounds like you dig those Ionic Breeze things. I have bad allergies, the fiance smokes, I've been known to fire up a cigar on poker night, etc. They are pretty high dollar, are they worht the money? I'm not impressed with the HEPA type Honeywell filters I use now. I think there is a way to e-mail me privately with your comments, though I don't know how to do it. Since air filters are kinda off topic around a Q forum.
In an attempt to redeem this post as relevant, I would advise a new Cookshack user to use a wired probe thermometer, and a basic probe dial thermometer. You can pick a target temperature to hit with the wired digital probe, and not open the door until you reach that temp. When you hit that temp on the wired, use the basic dial probe therm to check the meat. Use the probe to test for tenderness. If it slides into and out of the cut easily, the meat is getting to the done or tender stage. For a new user, the reading on the probe can serve as a guide for future cooks, providing you take Smokin's advice and keep a journal. The reason I suggest the wired remote thermomter is that many folks feel the need to "check" on the meat being cooked. This can get excessive, and everytime you open that CS door, you increase your cook time and release humidity that keeps your meat moist.
As for the wireless units' reliability, I don't know. I use a wired model, with the Pyrex name. I would imagine that the name brand isn't so important, there is probably one factory overseas that makes these things, and the companies stamp their names on them. We use ours for cooking chicken breasts in a smallish commercial Cookshack. I think it's a model 70, but would not swear to it. Anyway, we've been using the wired therm for about 8 months now, and have had one probe fail. This is using it every single day. FWIW, it WAS the probe that failed. I bought a whole new unit 'cause I didn't want to mess around looking for replacement probes, and the old control unit worked fine with the new probe.
