Hi everyone,
I am acquiring/ trading for an NO2 from a friend, and had a few questions. I am gonna spend some time reading back through this thread, very informative (thanks to many), but had a few quick questions:
My friend has had the unit for ~6 months, and has been using it without a bottom screen for a while (he says he has used it pretty lightly over that time). The unit definitely still works, I have tried it several times, but I'm assuming continuing to use it with no bottom screen will shorten the units lifespan. Is there anything I should do to clean it? It looks in okay shape, but in the chamber there are a few small brown marks (next to the 4 holes).
Is there a suggested place to order more screens? My friend says he ran through the screens provided very quickly, and didn't reorder more and the shop he bought the unit from didn't have any. The top screen is still in, I am going to clean with with alcohol when I get it. Any advice on how to make the screens last longer? He said the fact that the bottom screen got dirty quickly was his only complaint with the unit.
The unit seems in pretty good shape, it heats quickly, and I have zero complaints of its efficacy when I've tried it. Should I avoid using it at all under I can get more bottom screens, is this going to break the unit? Thanks so much, in addition to this I have already learned a lot from reading part of the thread.
