Digital Hygrometer and Indoor/Outdoor Thermometer In One!
We have a bunch of these hygrometers scattered throughout our house as I like to make sure that the humidity level is being kept under control, preferably no more than 50% humidity. Above this humidity level is when both mold spores and dust mites can start to breed. By using these hygrometers I have peace of mind and so can you. Priced at $39.95 and it also features a thermometer and clock.
