I've been using this for alittle over a month and this is my assessment. Pros: I love how the light changes based on the air quality. Green for good yellow/orange for moderate and red for poor. I've tested this by placing it on a dusty shelf and then using a can of compressed air to clean the shelf, the light immediately turned red once I kicked up all the dust. I like how its portable and can use this anywhere from your bedroom to your car to even work. The air filters are reasonably priced at about $10 from LG website and $15 on Amazon. Although LG website is always sold out I was able to purchase a couple of new filters once they were back in stock but they quickly sold out abson within a couple days. Best Buy does not sell replacement filters. The filter is already full of dust after one month of use. There is also an app that you can use with it, its not necessary but it does keep track of the air quality and you can even change the fan speed through the app and even turn it off or on. The Puricare air filter has 4 fan speeds Auto, Low, High and Turbo. The low setting really dosent move alot of air but it does save the battery. Turbo works best but it only stays on turbo for 30 minutes then automatically switches back to its previous fan speed. High/Turbo fan speeds drain the battery pretty quickly, maybe around 2 hours worth of battery if left on high. The battery will last about 6-8 hours on low. The good news is you can plug it in using USB type C plug and keep it running all day no matter the fan speed. It has a nice leather strap for easy transportation. It retails for $200 wich is alittle high in my opinion but I got it on sale for $150. I have read other reviews that said they got it on sale for $100 which I think is a fair price. The indicator light is very bright so thats something to consider if you're planning on using it in the bedroom at night. All in all I am happy with the purchase and recommend this for anyone looking for a portable light air purifier.

It works! I like how the light changes depending on air quality. Wish Bestbuy sold the filters though, Lg has them on their site for $9.99 each with free shipping but they are sold out. Amazon has it for $13.19 each. Anyway, I like how you can also check the Air Quality via Bluetooth through your phone or tablet.

good quality! good design! good performance! highly recommend!

Bought this to take with me while driving around, and for summer fire season. Was on a deal of the day around the start of Jan, so I figured I'd try it out. Pros - It seems to be built well, the strap is nice, Auto mode changes the fan speed pretty quickly if it detects anything in the air. Pretty quiet, even in a bedroom. Fit into my Suburban's front cupholders pretty well. Cons - Maybe it'll work better in warmer climates or in an office, but it's been between -20F and 30F the last month, and I can only get maybe a little over an hour of operation at a time even on the lowest settings. Took me around 24 hours to charge it back to full afterwards, and that was using a decently powered Anker usb charger, so with that I can only use it every 2-3 days. LED lights are too bright for a bedroom if you're trying to sleep. I **really** wanted to like this, but since there's only 3 months of warm temps where I live, the battery life and charging time isn't going to work for me. Have to return it.

I love this, using it for my laundry room and bathrooms when I travel and stay in older homes. Seems to work well! I keep it plugged in. Yes you need your own cord/adaptor but most of us have those these days for our phones. I'm not sure how efficient it is, but so far it seems to be helping with my mold reaction in musty rooms I have to go in. It has a buzz, not loud, but also quiet enough for me to use next to the bed at night. Its a little pricey but hopefully that means its efficient!
