Airflow, Coverage, And CADR

HAPHID Plug In Negative Ion Generator fanspeed

As a filterless plug-in air purifier, HAPHID Negative Ion Generator has a very limited airflow output. It can only cover a small area and has to be placed close to the sources like near the hallway, bedsides, dorm, staircase, bathroom, and walk-in wardrobe. Given this is an ionizer, CADR is not applicable here.

Filters And Performance

HAPHID Negative Ion Generator emits up to 32 million negative ions per second with forest-like air quality. It cleans indoor air from harmful substances and odors such as secondhand smoke, mold, and pollen. The negative ions will negatively charge and attach to positive ion particles in the air. The attached ions will then fall on a surface and remain there until it is disturbed. If you have an air purifier next to it, the particles will be pulled and trapped inside the HEPA filter instead. The entire purification is safe, filter-free, and can be reused over and over again.
