This humidifier came right on time. My daughter and I suffer from seasonal allergies, and we both were congested. I plugged this baby up and it made it much easier to breathe. It cleared the air and made it fresh. I especially like the compartment for essential oils. I put in a little peppermint oil and that opened up our nostrils and made breathing even better. The best things about this humidifier are, it’s filter free, easy to clean, adding water is a breeze, and it keeps the air ideal for anytime of day, or when you’re congested. This is definitely a great buy and I highly recommend having it.
