I bought the Miko air purifier a couple months ago. I could tell a huge difference in my air quality from the start. Nose bleeds have significantly been reduce! Headaches and coughing no more!
This little unit does a lot and keeps the air clean and free of dust and allergens. It is extremely quiet. It wouldn't even know it's there except for the soft glow of the blue light. I highly recommend it.
We have only been using it for a little over a week. It was very easy to set up, connect to app, and register. Very quiet operation. Only reason for four stars, is because we have only been using it for a short time!
