“The Sterra Moon does what it says!! It keeps my room cool, removes odors from the air (especially smoke from cooking!), it has removed dust from my bedroom, and with the app, I am able to monitor my filter, schedule on/off times,etc. The only thing I have not been able to monitor is the daily electricity use! Maybe someone can help me out with that one! LOL! Overall, I am very pleased with my air purifier!! I would definitely get another one if it was needed!! Thank You!!”
