I actually had to purchase this from Walmart, because Amazon refused to ship it to me in California for some strange reason. I paid $34 for it, and it was an absolute steal at that price. I came here to tell everyone where to find the filters, because even the manufacturer refuses to give the slightest clue to this... Do an Amazon search for \"Pure Enrichment Mist Air Eva Humidifier filter\". I haven't bought a replacement filter yet, but they *seem* like they are the exact filter in this unit! Again, I have not validated this, but they are visually identical, and this is the closest I came to an answer after over an hour of poking around online. Attached are two pictures of the filter from the unit to help other customers. Overall, this thing is great for small rooms, though. My other humidifier is a $250 Levoit, and honestly this one really competes well with it. Just keep in mind it's for small sized rooms. It puts out a lot of water, though... if you use the max fan speed, you have to refill it every few hours, which is a good thing because it's got a decent sized reservoir.
