Virus Trap

Introduction

A new filtering device can protect you from allergens, viruses and ultra-fine particulate matter in the air. Known as Soft X-ray Electrostatic Precipitator, the device uses soft X-rays to electrically charge airborne particles, which are subsequently drawn to an oppositely charged metallic collection plate and get destroyed there. Traditional air cleaners trap some airborne pathogens but are not very efficient at trapping those in the submicrometer and nanometre size range. The new device has overcome this limitation with the use of soft X-rays.
