The pre-filter is a relatively wide-angle filter that captures the largest airborne particles in diameter. This process also protects the main True HEPA filter from these particles and thus increases the lifespan of the HEPA filter.
Silver nanoparticles have excellent antimicrobial properties. When in contact with bacteria and fungi, nanosilver affects the structure of bacterial cells and prevents their growth.
HEPA Type 13 Filter [True HEPA]
The True HEPA (High Efficiency Particle Arresting) air filter is made of tiny glass fibers, which have been turned into a densely woven paper. This creates a filter consisting of a multitude of very small "sieves" that can capture extremely small particles, including some biological elements. Once pollutants and particles are trapped in the filter, they are not able to be re-released into the air due to the high absorbency pores of the filter. The True HEPA filter removes over 99% of microscopic particles (less than 0.3μm in size) such as pollen, dust mites and spores of fungi and other particles such as bacteria, etc. The HEPA filter should be cleaned frequently outside the room. We do not want captured particles to be re-released into the air.
Activated carbon filter
The activated carbon filter of AERO is granulated activated carbon and has a large total area and a high degree of efficiency. The pores are highly absorbent, forming a strong chemical bond/attraction to odors, gases and polluting liquids. It is the best type of filter in the retention and neutralization of chemicals, gases, odors, volatile organic chemicals (VOC) and cigarette smoke, which the HEPA H13 filter cannot retain.
Kullhaus Ionizers Air Purifiers have an ionizer. The air ionizer produces negatively charged ions. Charged particles tend to adhere to polluting particles of smaller particles in the air of the room and charge them statically. The charged particles then tend to accumulate with other particles and form larger clusters, which can then be more easily absorbed by the air purifier filter.
