To reduce the dust getting into my cheap quality (but still enjoyable) projector.

Does anyone have experience with either of these?

Since apparently my LED projector is actually halogen and other fake products I have bought on Ebay, I wanted to know if these actually generate negative ions?

The real question you should be asking are ionizers any good to start with (and might be downright harmful to health). Tests have shown over and OVER again that these things do a really poor job at cleaning air and produce ozone that can harm the respiratory tract.

Want clean air? Get a HEPA filter.
