Just to add one more point on the whole wood stove and air quality topic. It is also a good idea to have your home tested for radon. If it is over a certain amount you need to have it mitigated. Too much radon exposure is very bad for the lungs and they say even as bad or worse than smoking. When we finally had ours tested it came back very high. Once it was mitigated it now tests as lower than the radon levels outdoors! Anyway just another air quality point. Sorry if this opens up a new can of worms!
