- Does it actually clean the air?
- It emits negative ions, which can make particles settle, but it has no fan or filter and no rated clean air delivery. Treat it as a personal ionizer, not a substitute for a HEPA purifier or ventilation.
- How long does the battery last?
- The listing does not state a runtime. Expect a few hours per charge at most for a device this size, and plan to recharge over USB between uses.
- Is it safe to wear all day?
- It is a low-power consumer ionizer with no moving parts. People with pacemakers or respiratory conditions should check with a doctor before using ionizers regularly.
- Does it make noise?
- No. There is no fan, so it is silent apart from any indicator light or beep.
- What comes in the box?
- Typically the unit, a lanyard and a USB charging cable. Check the listing for the exact accessories.
- Can I use it on a plane?
- Yes, it is a small USB-rechargeable device with no lithium battery restrictions beyond normal carry-on rules. It will not replace cabin ventilation or a mask.
- Where is the Portable Neck Negative Ion Generator - USB Rechargeable Personal Air Purifier for Travel, Office & Commute cheapest?
- At SmartHomeValueHub, for $52.68, as of our latest check.
