2. Particle Removal & Collection
Certain technologies have little effect in removing solid particles from the air. UV purifiers or ozone air purifiers without a separate ionizer (such as needlepoints, many only produce small amount of ions as byproduct) and/or a Hepa air filter will not be able to remove dust and other allergens from the air, the most common types of airborne pollutants people want removed.
Ionizers without a filter can remove solid particles, but do not actually collect much of the particulate. Hepa air filters, such as the filter used on the New-Aire Air Purifier, capture allergens and other particulate, removing them from the environment, while preventing them from re-entering the air.
