This thing made such a phenomenal difference to my allergies just within 10 minutes of turning it on in my bedroom. I have no idea how I ever lived without it. I don't wake up in the morning with blocked sinuses anymore. The sleep mode keeps it quiet and the LED lights dimmed so no issues with it waking me up at night. I would absolutely recommend this air purifier to anyone with allergies or asthma.
Effectively cleans the air from smoke and large dust particles. It reduces general dust but doesn't eliminate it, probably because the exhaust of cleaned air circulates the making it hard to clean it all, I'm not sure how a filter can work around. It's easy to use, easy to clean and it looks nice.
