It’s tough seeking out the best air purifier because there are so many different kinds and so many factors to consider. But if you’re looking for the best personal air purifier, something to bring along with you on road trips or a plane, then you would do well to consider the Wein AS300.

Why We Like It – Wein AS300 Personal Air Purifier

Wein AS300 Personal Air Purifiers are powerful units for being so small. Their range covers what it needs to, your face, and it does a great job like it. The powerful air travel and astounding ion output protect against all manner of contaminants from dust to mold spores.

  • Long Battery Life
  • Protects Against A Wide Array of Contaminants
  • Very Portable and Lightweight
  • Only Protects, Doesn’t Destroy
  • Customer Reviews are Good but Scarce
  • Expensive


The Wein Air Supply AS300 propels cleaner fresher air to you at a rate of 75 feet per minute. At this rate, you’ll always have fresh air wherever you go. Further, the battery only takes three to five hours to charge and lasts a solid 28 hours. It may not be the best battery we’ve seen, that award goes to the Airtamer A310, but it should be long enough to get the job done.


It’s hard to establish the range of effects that a personal air purification device is capable of considering it just propels air into your personal breathing zone. And as long as you’re wearing it, it should do its job just fine. So whatever the size of your face, that’s the range. If you would like something a little wider, check out the Dyson Cool Me.


The AS300 Wearable Air Purifier protects your personal breathing zone from dust, mold spores, pollen, smoke, viruses, fumes, odors, and even allergens. It’s similar to the Oion Technologies air purifier, except you can’t wear this one around your neck. So for those looking to be healthier or who do have allergies, it works for both. It does protect against smoke, as I’ve said, but if you want something specifically for smoking. You may have to take a look at our Vornadobaby Purio Air Purifier review if you have a baby and need to have their room purified.


The AS300 weighs only about 5 ounces, so it should be no problem to wear around your neck while you’re on the go. It also comes with a strap to hang around your neck and a USB charging cable, which is similar to the Smoke Buddy air filter. Of course, if you’d like to set it close to you instead of around your neck you can. Its effectiveness may decrease if you do this though. The on/off button is located at the back and is a lot more durable than previous models too.


The Wein AS300 works by emitting 50 million ions per cubic centimeter. And these are negative ions. Truthfully, this is great ion output for such a small device. Customer reviews are positive if just a little scarce. It currently has a 4.5/5 star rating on Amazon based on 52 reviews. It is a little on the expensive side though so you must be sure this is the one you want.

Wein AS300 Personal Air Purifier Wrap Up

The Wein AS300 is a seriously powerful device for something so small. It’s long-lasting and should be able to last all day and then some on a single charge. It’s expensive, though, so make sure you know this is the one you want before buying. But if you do you’ll find a great friend in this little device.
