The curtains themselves are fine. They are sheer enough to let light through, but you still need a shade behind them to keep people from looking in. We use them in our spare bedroom where my fiancee hangs his ice hockey pads up  to dry, Not that I was expecting a miracle but I'm not sure these really do much of terms of odor neutralizing. I would still by them again for the quality and hope that they actually do neutralize odors. I just think the odors in our room are a little too excessive!
