Question: does this product have a glass bowl or plastic?
Document: First of all, I own a Goodsphere. It's the exact same product, but by a different company. This type of item, I first noticed, was being sold in Europe and I bought mine after doing an exhaustive search for some type of aromatherapy diffuser that would have a glass bowl. I had originally owned a Homedics Brethe machine and the plastic bowl would become stained with the scents added to the plastic bowl.
A stained up plastic bowl of swishing water is hardly attractive. I also noted that some of the essential oils were also degrading the plastic bowl, fearful I would eventually end up with a hole in the plastic, I needed to find a glass bowl that would neither stain or degrade. So...my search resulted in finding the Goodsphere. My machine looks exactly like the one pictured here, except my lid is white.
It works well. I have been using it with essential oils, which makes me wish that is was made from glass.
Recieved this product and it does not work as a humidifier.. It just spins with pretty lights..I do not recommend if you want a cool water humidifier.
The air purifier is loud but  cleans our room of dust.It would be perfect otherwise .I would recommend this product if you are not sound sensitive.
I was  little reluctant to purchase this product after reading some of the reviews. But it works well, it's quiet and makes the air in my daughter's room smell good. I have had it running for 4 days and just had to add more water today.
it doesnt make it smell better for long. It works well for purifying I think but not for aroma. but worth it.
Yes it was just what I had been lookingfor, it's great and easy to use. Will recommend to friends.Thanks
Wow the reviews on here are fasle, they didn't buy this item, for one thing it doesn't have lights, it works perfect, i love this thing, and the best part of it, it catches alot of mosquitoes, we are going to buy another one for the living room.
This is a great room air freshner. It does trap some dust and pollen as well. Water needs to be changed out twice per week, but overall it is a great buy
Answer: Plastic, if you want a "humidifier" dont buy this.. I brought this because of "aroma theraphy" and with that it serves its purpose (but only for 10mins) until it became defective... still waiting for sellers response
