Rated 5 out of 5 by from VERY GOOD AIRPURIFIER I bought this 2 weeks ago, and i feel the difference before and after purchased. It functions very silently to remove bad odor and dust! When i go sleep, i don't even feel that its functioning! I like their filters inside becuase it can be washed after 6 months so very economic for me!

Rated 5 out of 5 by from This sits in a room that gets a lot of dust daily and works like a champ! I used to have to dust daily and now I only need to once a week! It's super quiet and keeps the air clean.

Rated 5 out of 5 by from Great feature and silent!! I bought two of this air purifier due to new paint and new dog. It works very well, and very silent. And always I can monitor the current air quality including dust level with the light color. I'd like to recommend this one to everybody who has dogs or want some fresh air in their room.

Rated 5 out of 5 by from Excellent Air Purifier product My boy is 2 years old, and he runs a lot in the basement a lot. Our basement floor is a carpet, so I always felt dust in the air. I decided to purchase a purifier. I purchased this product a couple of months ago, and it works great. Before my boy is running, it displays "green: means air condition is good," and it runs slowly. While my boy is running, it displays "red: means air condition is bad," so I can recognize the air is not good, but the purifier cleans air quickly, and I don't feel dust in the air. As well, it doesn't have noise, so my boy is not scared of it. I feel my choice was right. Thanks LG~

Rated 5 out of 5 by from Best purchase ever for an Allergy Sufferer I am a Spring Allergy Sufferer in Georgia I purchased the tower for my bedroom. I have to say it was the best purchase ever !!!. I am able to sleep at night without the stuffy nose and burning eyes. It is so quiet, I forget that it is the room. When I have the indicator light on, even when I walk around the bedroom, I can tell it is working hard catching the carpet fibers in the air. I borrowed the smaller one from a work colleague to put next to my desk. I will definitely purchase one of my own to keep the air clean around my work environment.

Rated 5 out of 5 by from Sleek Design & Whisper Quiet Air Cleaner We received the unit as part of the Product Review Sampling Program and we've used it for several Weeks. We're very pleased with the results the unit delivered and the styling of the unit. Although we haven't had the unit long enough to go through the maintenance of the filters, it appears to be simple to clean and/or replace based on the instructions. We initially placed the unit in our master bedroom and really noticed the improved air quality with less dust and 'cleaner' smelling air. We currently have it in our rather large open great room where the benefits are not quite a noticeable which is expected. We loved the LED glow that it provides that works well as a night light. However, it can easily be turned off if desired. The unit is extremely quiet such that it did not disturb our sleep when it was in the bedroom. PROS: - Easy setup with clear instructions with lots of pictures - Sleek design that blends to any decor - Whisper quiet operation - Solid performance delivering cleaner air CONS: - Wished it came in colors other than white - Unit is relatively large if one is trying to conceal it

Rated 5 out of 5 by from Sleek, Quiet and Amazing Air Purifier I received my air purifier and have been using it for a couple of weeks now. We have a dog and my wife and 2 boys have a lot of allergies. I leave the purifier on automatic and it seems to do it's job very well. My wife and boys have been telling me they are able to breath better since we got the purifier. Since receiving the product we have had much less allergy symptoms and we all sleep better during the night now. When any type of odor happens, the purifier quickly removes it from the air and the house always smells fresh. I have the purifier located in the living room, which is a central location for most activity. I have to say I was shocked on how well it really cleans the air in the house. i have not yet had to clean the filters, but even that seems very easy to do. Great product, very quiet, and with it being a tower, does not take up a large space! Highly recommend it!
