In this article, we look into what wearable air purifiers are, how they work, and whether they can really protect against pollen, and other pollutants.

Wearable Air Purifier Necklaces: What Are They?

Wearable air purifier necklaces work differently from typical home air purifiers. They typically use ionizers and ionization technology as a means to filter out pollutants from the air.

Most non-portable home air purifiers, on the other hand, use HEPA filter technology to filter out pollution.

Wearable ionizer purifiers work by emitting thousands of ions into the air every minute.

These emitted ions adhere to pollutants in the air, giving them a static charge. Just like a balloon sticks to a wall when it’s been statically charged, the charged particles are then more likely to stick to whatever’s near them.
