Seriously? So out of all of that only newbie9 is the only one to even attempt to offer any type of advice whatsoever. So thank you i really appreciate that. And I agree growindank about the writing, but apparently the formatting does not come through. I also apologize for writing so much, I'm used to writing longer educational speeches, which I now see is not needed here. All I asked for was information because of my ADMITTED IN-experience. Never once did I try to sell anything. I have 192 commercial, residential and industrial IAQ products in my catalog, each doing something slightly different. So I thought, hey maybe some nice stoner (apparently not the friendliest) "friends" could help me narrow it down a little because, like I said, again, I am IN-EXPERIENCED. I never once claimed to know anything 100% (except for IAQ). I believe I even said, I wasn't sure it was even a problem. And yes you are correct, if I could get something that worked better then yes I would make it available for people to purchase, just as I will have to purchase, and I will add extra money to the product, for me, for said product. If you can find someone giving away equipment or materials and not making any money on it, please let me know so I can start purchasing from them. Look, all anyone had to say was everything we use for air quality works well enough, there are no problems. Which I know is not true, from reading posts. Sorry, I'm being long winded again. Appearantly I have nothing to offer here, so thank you for your time.
