Review on BATEERUN True HEPA Filter Air Purifiers - Ultra-Quiet Air Cleaner for Bedrooms and Large Rooms (2 Pack) by Elizabeth Morton

If I had known that this air purifier did not come with instructions I would not have bought it. You can't even find a guide online on the Revain website or anywhere you try to find this item on google. So basically I have a product that I can even open up to change the air filter when it comes time to change it out. This was a real disappointment but I will make sure to really research the product before buying in the future.
