The box stated 750sqft not the 1375 posted in the listing. No option to turn on off individual features. Also no option to keep uv on night mode. The top light is too flashy and over the top, I want to just turned the light off but kee UV feature on. Also no option to display temp n humidity all the time. Tech specs not listed anywhere. I am returning n getting something else for a unit in this price range I can get better features elsewhere

This HEPA filter has been phenomenal. It tells me the air quality, and I love the range in the fan settings- when it's on low it's almost silent, or I can turn it all the way up and have the airflow very high. This week my niece came to stay for a couple days despite having some kind of bug she had picked up from her friends, and it's been priceless knowing that the air is clean. The unit is well designed and unobtrusive, and it has a useful handhold in the back to make moving it easy. I'm very, very pleased with it.

This product has worked wonders for my household. We have a dog and my son is constantly sneezing and coughing because of his allergies. Every since we've started using thus product he now barely sneezes and cough. The air seems much cleaner in our home. The quality is great and we just love it. The style is also nice where it fits in with out decor.
