I have this one from Amazon and it is great! It serves my entire living room. I probably only have to refill it once a week. For reference I have 15 plants in my living room including multiple Xmas cacti and a gigantic boston fern. I have a bromeliad that sits right next to the humidifier.
Awesome features of this humidifier:
Overall I can't say enough good things about this product.
1Gallon tank last all night with one fill and I refill in the morning and keep it going all day to make sure there is moisture in my room at all times. Totally worth the price
