Comments about Solid Air Freshener - Citrus - 20 oz:

With two Siberian Huskies who stay indoors during much of our blistering Louisiana summers, odors can be a problem. This product has been the most effective of any of the many items I've tried. With the large size, I place it in the central air
return and it works for the entire house without being overpowering. You don't even notice until you come in from outside and smell a subtle citrus
scent.
It doesn't last as long as claimed, but that may
be because of how I use it (in the a/c vent). I did get two solid months of use, which I'm satisfied with. I would recommend this if you have strong odors to deal with. I have reordered and plan to continue using it.
Wag.com's service was VERY fast. I think I've found a new source for my pets' needs.
