  • Awesome lil machine

    I had A humidifier from Walmart and then I ordered this one. I had the old one in my bedroom and the new one in the living room. The one in my bedroom died so I had to move the newly purchased one in my bedroom. Im in the living room a majority of the day and my nose is stuffy and dry. But when I go to bed and wake up I feel great. Im going to order another one for the living room right now. I love the indication light but its low on water and it seems to run forever before you have to refill it. I would recommend buying a product to mix in with the water so that fungus algae doesnt grow.
