Product review (5 stars): Great Product. Must Have.
This is a must have item and so cheap too. I used my Vornado evaporative humidifier a few  years but did have quick mold\gunk issues on the filter. Using this which is so easy i don't get that type of build up and feel safer on the air going in my master bedroom. I still  have a bottle which will last me a while but will buy another before it runs out. Smell is just normal so no difference there.
