Car Air Purifier Ionizer, 12V Plug-in Car Air Freshener Gadgets with Dual USB Charger Removes Cigarette Smoke, Pet and Food Odor, Ionic Ozone (Silver)

Some people are saying this device doesn’t work; I don’t know whether they got defective ones or whether they just don’t know what to expect from an ionizer, but I can tell you mine works. I know what a functioning ionizer feels and smells like, so I plugged this in and immediately got close to it and took a whiff. Not only did I smell the negative ions but I started feeling unwell within a minute or two, which is a risk with ionizers. Their proper functioning involves the emission of ozone (that’s what you actually smell when they’re working), and exposure to too much ozone can cause health problems (I didn’t realize this when I conducted my little test). This is not a mark against this device; my having felt that way after getting right up to it and snorting the ozone (a not-very-bright move on my part, I guess) simply proves that the one I got works. I’m also more sensitive than many people are to various physical stimuli, so what makes me feel yucky probably won’t have that effect on a majority of people. Exposure to negative ions/ozone in moderation is a good thing; running water gives off negative ions, which is a major reason waterfalls are so exhilarating to be around.As with all ionizers, you’ll want to use this one with care, and not more often than necessary. But 4WDKING generally makes good stuff, and provided the device you receive is not in some way defective, it will do what it says on the tin.I’ve only used it for a few hours so far so I can’t speak to its longevity, but it did do a nice job of cleaning food smells out of my car. I’m a vegetarian, more or less, and I drive for DoorDash, so I bought this device primarily to eliminate meaty and other unwelcome food smells from my car, and it does seem to do the trick.Not all cigarette lighter sockets (and things designed to go in them) are created equal so I can’t know how it will behave in other people’s cars, but while some other inexpensive devices have exhibited the problem reported by at least one person of not staying in the socket, this device does stay put and functions just fine in the lighter socket of my 2019/10th-generation Honda Accord, even while traveling over bumpy roads.One person talked about metal construction while in fact all the external parts of this device are plastic. But the grille thingy on the business end is chromed and could reasonably be mistaken for metal. The blue light is kind of bright, but it blends perfectly with the blue factory lighting in my car and I don’t find it distracting at all; quite pretty in fact.In summary, I’d say, based on my limited experience, that if you’re looking for an effective air purifier for your car, giving this one a try is worth your while.

My son bought a truck that had a lot of smoke smell. He tried a lot of other things but this seems to work great! It’s small, makes no noise and it lights up at night. He loves that this is working and is going to buy another for the back seat since it is so small and doing a great job.

I couldn’t tell a difference at all in the air quality. The light is semi distracting at night while driving so it would be best to put it someplace the driver can’t see. Not all vehicles have that ability

I smoke and it's made my car smell so much better.

I have this in the cab of a pick up truck, with only a bench style front seat. Not an extended or crew cab. I'm not really impressed with it.The USB charging ports seem to work well though, and the blue light helps me see if tye cords have come unplugged.

Purchased this for my son who just got a used car with no USB ports. This small plug-in cleans the air (no odors!) and provides helpful USB features. The blue light on it is kind of annoying, but you get used to it. I do recommend it!

let me start by saying i bought a couple different brands of this same item to hopefully find one that can actually get rid of stale ciggarette smoke smells from my car interior. This is literally the only one that worked from the first time i plugged it in and it continues to work just as well weeks later. hooray

I do not notice a difference and for the money- don’t bother.
