Hello there,
We have a new air purifier to be released, before that, we want to test the functions of this item to see weather all of the fuctions are good or not.
For this program, we need a report about your using feeling (including the item’s function, usage experience, and your advice about this item)
Please contact with me if you are in United States and used air purifier before :)
Hello, Hope you are doing well. I have used them before specially in high pollution zones. I m currently in west coast and can give you a detailed feedback.
