gave as bday present for aunt who has allergies. As soon as we turned it on, air feels so refreshing and clean. It is easy to install. Not 5 stars as we just started using it.
I've had my Ibuki+ for almost a year. I can definitely tell the difference in how I wake up in the morning. Before, I always had dryness and sometimes a sore throat, but since using the Ibuki+, I've slept better without irritation in the morning. I also appreciate the My Miko app as it allows me to register my device and order the correct filter without second guessing which one is the correct one.
