Product review (5 stars): A good solution to keep out bacteria and mold.
If you use a filter-type humidifier then bacteria and mold will eventually grow in the device and especially the filter. When you run the humidifier, air is pushed through the filter and the bacteria and mold are pushed out into the air you breath. This can pose a health issue - particularly if you are prone to allergies. Bacteroistat solutions keep that from happening. The Sunbeam solution seems pretty simple, but seems to be pretty effective. The use of this kind of solution also helps keep the filters from hardening - making them useless. This product seems to be as good as others that cost more. Save a few $$$, extend your humidifier filters life and be a bit healthier.
