JINPUSAir Purifier Small Portable Air Cleaner for Bedroom with HEPA Filter, Upgraded Low Noise Home Air Purifiers GL-2103 (Powered by 4.9 ft USB Cable, No Adapter)

Placed this next to my bed for a week and then placed it farther away. After having a very stuffy night sleep I put it next to to my bed again. Definitely noticed a difference. This air purifier is only for small rooms. Works great for those who have allergy problems while they sleep. The blue light and noise doesn't bother me because it's so soft. But if you're really sensitive to noise or light, it might bother some.Update: 7 months laterStill works but with an annoying quirk. If it drops or you pick it up and move it to a different location it automatically turns off. The USB cord connecting to the unit - If it's loose it turns off. This is definitely only for very small areas. I have it in a micro apartment next to my bed. I would say that it covers half the space of a micro apartment. Good for desks and bed tables.

Picture shows how the filter looks after 3 months (running practically 24/7). I'm so impressed! It really is catching a lot of dust!I don't have any solid proof if I really have less mold particles in my air, but there is certainty proof it's catching the dust. I just got this filter because my college apartment has some mold issues. I use this filter in a small bedroom that also has a bathroom connected. I have indeed had less headaches since getting this, but I'm still not sure if that's a coincidence or not because headaches never were a huge problem for me, just something infrequent - but they still happen less now.I saw people complaining about the light, and it's true it doesn't go completely off, but there are 2 settings. Personally I like how dim it gets but if it's still a problem for you, you could always hide it under a chair or something so the light wont go across the whole room while still leaving room for air to come out on top. The dimmest setting has never disturbed my sleep though. It's a very nice nightlight actually - beautiful blue shade, so this is like a 2-in-1 for me!It's extremely quiet, I can only hear it if everything else in my room is turned off, and even then it's still quieter than the AC. Still, when I hold my hand over the outgoing air, it's more/faster than I expected from this little guy.This thing is a tiny little beast and I hope to use it for many more years. Buy it! You just plug it in and it's ready to go!

This air purifier is small, quiet, and seems to do a good job (the impact isn't hugely noticeable, but I'm not sure it would be with any system, as we're focused on allergens vs. odors). A couple things to note, though:1) It comes with a USB cable but no plug, so you need to have an available plug or place to connect it (and it's not entirely obvious what wattage it requires - I'm using a 2W plug, which seems to work). Given how cheap usb chargers are these days, it seems odd to me that they wouldn't include the plug.2) When it says the night light can be dimmed, that's what it means. Not turned off, but reduced. If you're looking to put this in a bedroom for use at night, be prepared to have a blue LED on all night. And it can't be covered, as it's inside of the vent, so covering it would block the airflow.Besides those caveats, it seems like a nice product at a good price.

5-2-2023 New updateUnbelievable but it is still working great. I run this filter 24/7 and have since I purchased it.Nothing else needs to be said - Upgrading to 5 stars.Love it and highly recommend it now.----------------------------------------------------------------------------------------------------------------Update 7-5-2021The company is shipping a new unit to replace the broken one. I was offered my money back or a new Air purifier. Since I really did like the Air purifier, when it worked, I am giving it one more try and getting a new one.===============================================================================I liked it until I realized there was no filter. I contacted the Company thru Amazon and finally after arguing with them received a filter. Then the darn Machine stopped working and Amazon says to contact the company but offers no way to do so. It is less than 45 days since I ordered this POS and I am out the money I paid. I do not trust the company, the manufacturer, or Amazon for help. I am willing to bet Amazon refuses to publish this review.

Technically it works, but practically it does almost nothing. I got it to clean the air in an enclosed shower where the cat box lives, and apparently this 9 sq/ft area is a struggle for it. Looks cool, low noise, nice blue nightlight...but the main feature is lacking. Off it goes to Goodwill.

I’m a pothead, and I live with a cigarette smoker, and though some parts of the place may have more of a smell, believe me when I say my room (where it’s kept) has no smell in either direction. It may be small but it’s mighty. It has a cool blue color, which doesn’t change at all to let you know about air quality which is a con but it is a calm bit of light at night, has a bit of white noise to it but I like that to sleep with and it’s never rlly too loud

I can’t even tell if this thing is working. It’s VERY SMALL, I wouldn’t say it’s 360* air purifier. There’s almost ZERO AIR coming out of this thing. It’s super small, and may purify a room no bigger than a small closet. THAT IS IF IT EVEN WORKS..... there SHOULD be some air coming out of it, but there’s literally none. I did all of the troubleshooting- made sure nothing was blocking the filter (which is on the bottom of this contraption) anyone who says this thing is great, is either being paid to say it-or they’re flat out lying..... this filter is no bigger than a tea cup plate..... DONT WASTE YOUR TIME WITH GETTING THIS, bc I can tell you, you’ll return it as soon as you open it up. I WAS EXTREMELY disappointed with the description of the size .....**DON’T WASTE YOUR MONEY”
