What people are saying

Rated 2 out of 5 by from Works for a year 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

Rated 5 out of 5 by from Great Features! 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. I’ve noticed a big difference since we’ve using it.

Rated 5 out of 5 by from Awesome appliance! 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 that’s pretty neat and calming. There are lights that let you know the quality of the air. You can turn them off if you don’t 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 2,4,6,8,or 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. I’m 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 don’t 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. It’s More of a necessity than a luxury. We do have a humidifier on our furnace as well. I wanted a purifier. I don’t 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 wouldn’t ever give me that info. I do highly recommend this product!

How many square feet of a room can this air purifier handle effeciently? I cannot find the specs anywhere on the site and want to know if it can handle my 1150sqft house or if it is only for a small bedroom size.

OK so help me understand. If I’m using this in a bedroom, let’s say, would I be better served by keeping the windows open? Or closed? Referring to the carbon dioxide issue. Does it help any that there is a good size plant in the room? 

Asked by: Gmd833
The LG SIGNATURE Smart wi-fi Enabled Air Purifier, Model # AM501YWM1 should not be placed near a window or near the air intake or outlet of an air conditioner or heater. Doing so may cause the humidity sensor to malfunction. Regrettably, we are not aware of the "carbon dioxide issue" that you are referring to and will need some clarification. The air purifier's watering engine rotates at high speed spraying 18L water in an hour to infuse moisture in inhaled air. Atomized water is dispersed from the air purifier to create a comfortable humidity level. It generates an ozone level of less than 0.001 ppm. The 2008 ozone standard is set at a level of 0.075 ppm averaged over an 8-hour period...^IFV

One of the LG responses states: " avoid high carbon dioxide levels, you should not use it for long periods in a tightly enclosed space". What does this exactly mean? Is LG suggesting that this machine emits carbon dioxide into my house?

Asked by: Anonymous
That would be a correct interpretation of the response for the LG SIGNATURE Smart Wi-Fi Enabled Air Purifier, Model # AM501YWM1. It is recommended that you close outside doors and windows during use, so to avoid high carbon dioxide levels accumulating, you should not use for long periods in a tightly enclosed space. Much the same way you should avoid using a gas range oven in a tight space to avoid the accumulation of carbon monoxide while cooking. The point here is that since the doors and windows are closed, there is no airflow that removes an accumulation of carbon dioxide in a tight space as opposed to a more open space where the carbon dioxide is dispersed. Keep in mind that the global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years. The percentage of carbon dioxide in inhaled air is 0.04%...^IFV

I’m an artist and the fumes from my oil paints and mediums that I use can be strong in my studio where I’ll have to close windows in winter. Will the filter clean fumes?

Asked by: Artsea Lady
We are not familiar with what fumes your oil paints and mediums give off, but the LG SIGNATURE Smart Wi-Fi Enabled Air Purifier, Model # AM501YWM1 should not be used to remove toxic gases such as carbon monoxide. The unit has a Humidity Sensor that detects the humidity level, an Odor Sensor that detects odors in the air. It features a Dodarizing Black Filter that filters out unpleasant odors such as strong food odors or cigarette smoke, a PM 1.0 Black Filter that filters out super ultra-fine dust particles like fine sand or cigarette ash. You need to close the outside doors and windows during use, if possible, but to avoid high carbon dioxide levels, you should not use it for long periods in a tightly enclosed space. The air purifier's deodorizing Black Filter is designed to remove odors from the air. If the deodorizing Black Filter is exposed to excessive odors for long periods, it may need to be replaced more often. In this case, the filter itself may produce an odor. To rid the indoor air of strong odors, ventilate the area by opening windows or doors, then use the product to remove any odors remaining after ventilation...^IFV
