Review on RENPHO Large Room Air Purifier for Bedroom - Up to 720 Ft², True HEPA Filter Intercepts 99.97% Dust, Smoke, Odors, Allergens, Pet Hair - Quiet 26dB, CADR 170m³/h by Stacey Growe

Here is another quality product from Renpho. I never heard of the company until I bought their smart scale. That's incredible. This air purifier is very quiet. Has four speeds. Low, Med, Hi in normal mode and Super Low in night mode. Night mode is very quiet. It also has interesting light modes. Three white light modes, low, medium, hello. And has a color mode that has different colors and different intensities. There is also a breathing mode. It pulses with the intensity of the light, so you can use that rhythm to breathe. reassuring? To get different modes, either short or long press the light button. For example, to turn off breathing mode, press the light button for a few seconds until you hear a beep. Short press changes intensity or colors. The instructions aren't great on these features, so just play around. Obviously, when using this air purifier, there are fewer micro-dust particles in the air. Highly recommended.
