Review on Large Room Air Purifier 3-in-1 True HEPA Filter - Air Choice Smoke Filter - Reduces Pets Dander, Household Odor, Smoke, Dust - Sleep Mode, Auto Mode - Quiet Operation - White by Nina Lucero

I've been wearing this air purifier for several days because my new roommate was a smoker. I had enough smoke so I tried to find a suitable air purifier. Luckily I have this one. The coverage area of this air purifier is large enough for my 160 sqm. Feet so it can freshen the air in every corner of my room and I don't have to smell smoke anymore. It has improved the quality of the surrounding air and improved my quality of life. Besides the main function, it has different fan speeds and can automatically adjust the fan speed according to the surrounding air quality. At least I don't have to think about which mode to be in. And its sleep mode really surprised me because it was so quiet that I could read without any distracting noises. When using it, I could also see the sleep button flashing when the filter needed to be changed, and the step to change the filter was pretty simple. So far it has exceeded my expectations. I will try again if necessary.
