Bests & Worsts Reviews from Amazon

Everything about it is perfect. I live in an apartment with open floor plan. The kitchen and living room are the same space and about 750 SF. I placed my unit somewhere centered (see photo and video). - SENSOR/AUTO MODE - it has a PM2.5 laser sensor as you should expect. it works! My in-law had something cooking in the stove (I didn't know) and as soon as the smell hit me, the unit was already in Auto mode during the day, and it turned itself on ramping up that fan to get rid of the thick cooking air. minutes later it went back to normal once the air in the kitchen/living room was filtered. - CHILD LOCK - My 2 yo can't mess with it like with the other ones. The filter is big so it does move a great volume of air through it. It does what it says it does. I would recommend. PS. I'm a photographer, so that's why the video and photos look like that. I didn't download these from the internet.
