Product review (2 stars): Stick with the "older" version of this product.
This product is listed as a newer version of a product I've purchased in the past. The "new" product contains only 1/20th of the active ingredients of the "older" version. The ingredients are exactly the same, just much much less of each in the "newer" version.
 I highly recommend purchasing the earlier version by Holmes. The bottles look exactly the same but rather than the "Sunbeam" logo in red the superior product has the logo "Holmes" logo in black.  The prior version is about 50% higher in price but one would have to use twenty times as much as the newer version to equal the strength of the of the Holmes version.

As always Amazon handled my concerns superbly with the most amazing customer service.
