Works for a year

Submitted by nodari - 1/26/2021

Had this device for more than a year. It worked fine 12 months or so and then humidifier part basically stopped working. It complains about cleaning but does not help. My coworker has the same problem with his too. Too expensive for 12 months use

Great Features

Submitted by Jenny O - 3/2/2020

We live in a very dry dusty climate and have been looking for a humidifier and air purifier in one. This product definitely does the job. I love the option of having a timer. It makes using this very convenient. Ive noticed a big difference since weve using it.

Awesome appliance

Submitted by Tammie222 - 2/24/2020

This thing amazes me. When you fill the bucket with tap water and turn it on the machine automatically does a UV light treatment to purify the water. You can choose to purify the air turbo speed or silent or purify and humidify. The humidifier does a rain show thats pretty neat and calming. There are lights that let you know the quality of the air. You can turn them off if you dont want lights on. The humidifier function lets you set it from 30 up to 70. There is a sleep timer on the machine also. You can set it for 2468or 12 hours. The WiFi function is easy and also really nice to have It tells you what the air quality in your home is and even averages by the day week or month. You can use the remote to adjust the settings or you can use your phone and control the device through the app. Im so happy to have this purifier Our last home had mold and mildew issues and we were always sick. We bought a new house last year and I dont ever want to live in those conditions again. Being able to control the quality of air in my entire home and not just a room is like having a pillow at night. Its More of a necessity than a luxury. We do have a humidifier on our furnace as well. I wanted a purifier. I dont really know if the humidifier on the furnace runs less or more or not but I do know the percentage of humidity and the quality of the air and the humidifier on our furnace wouldnt ever give me that info. I do highly recommend this product

Breathe again

Submitted by Ortizsca - 2/22/2020

I used to have a cat and my partner was always sneezing and coughing. Even though I washed everything The house just felt like it had dust in the air. The LG purifier is the brand you can trust for quality and durability. Also the purifier is something I needed to have clean air without Opening the windows. It is very easy to set up just plug and fill the compartment with water.

Great in performance as well as looks

Submitted by V795 - 2/20/2020

First and foremost this product is not only an appliance but for me more like a piece of art which has been so exquisitely crafted. we were literally floored by the looks of the product and this is quite compact. Coming to the review I live in a place where there are lot of trees around and which in turn lead to lot of unwanted bugs. Due to the bug problem we prefer to keep our windows closed and we rely more on air-conditioner to get the air. I know this is not the best thing but I guess the bugs kind of freak me out. So this is a perfect product for us. Apart from looks the product works in a really good way. It tells you about the air quality in the room and then do the job. It also keep the humidity levels maintained and one can see the thing in action. Although its tough for a non-expert to comment on the purification of air but somehow we felt better after its use for last 2 days. Afterall the air quality indicator seems to reflect the same also. Above all this unit works so silently that unless someone notices you wont even come to know. Another thing which I liked is that it sterilizes the water it sprays beforehand by using UV technology. Its definitely a piece of art which does a great job. I am particularly happy with the product and can safely recommend to anyone. PS: It has got so many features that I am in awe of them. You name it and possibly its already there like odor control dust sensor water level indicator etc etc. Love it
