A personal air purifier is a compact device designed to cleanse the air in an individual's immediate vicinity, usually covering a small area like in a room or a car. Unlike larger air purifiers that serve entire homes or large spaces, personal air purifiers are portable and can be worn around the neck, placed on a desk, or kept in a car. These devices utilise various technologies to filter out pollutants such as:

• Dust particles
• Pollen
• Smoke
• Microorganisms like bacteria and viruses
• Other airborne allergens

They are especially beneficial for those living in urban areas with higher pollution levels or for individuals with allergies or respiratory concerns. By ensuring cleaner air intake, personal air purifiers can assist in improving overall well-being and reducing exposure to harmful airborne particles.

Personal air purifiers have garnered attention for their promise of delivering cleaner air directly to the user. These devices work by utilising technologies like ionisation or HEPA filters,to capture or neutralise airborne contaminants. The efficacy of a personal air purifier often depends on:

• The type of technology used
• The quality of the device
• The size and concentration of particles it's designed to target
• Environmental factors such as air flow and pollutant levels

While many personal air purifiers can reduce certain pollutants effectively, they might not offer complete protection against all types of airborne contaminants. For best results, it's essential to choose a reputable brand and understand the specific threats you want to mitigate. It's also worth noting that while these devices can complement larger air purifying systems, they aren't a replacement for them in spaces with high pollutant levels.

A Necklace Air Purifier, such as the AirTamer, is a wearable device designed to create a clean air zone around the user's face. The primary mechanism behind the AirTamer and similar devices is negative ion generation. When switched on, these purifiers emit a stream of negative ions. Here's how they function:

• Negative Ions Emission: The device produces and releases millions of negative ions into the air.
• Particle Attraction: These negatively charged ions attach themselves to airborne particles like dust, pollen, smoke, and bacteria which are generally positively charged.
• Particle Neutralisation: Once bound to the negative ions, these particles are attracted to positively charged surfaces which removes them from the air, away from the user's breathing zone.

It's important to understand that while necklace air purifiers can reduce the number of particles you breathe in, their efficiency also depends on factors like the surrounding air quality, the number of ions emitted, and potential interference from clothing or hair, and whether they are used indoors or outdoors.
