How can UV-C light, a natural product of the sun, help purify indoor air? It all has to do with the UV-C light’s ability to destroy cells. UV light harms cells by destroying nucleic acids and disrupting their DNA, which either kills them or leaves them incapacitated. After prolonged exposure to UV light, cells are unable to perform their vital functions.

With an air purifier with UV-light technology, the air is pulled into the appliance and then passes through an internal filter chamber where it is exposed to UV light. The UV-C light is not released into the room, so you won’t see it nor will you be exposed to it. The air will then go through another filter before being released into the room.

Because UV light is effective in killing cells, it is therefore effective at eliminating living airborne organisms. Namely, mold and mildew.

Mold reproduces through spores that are released into the air, much like pollen from a flower. The mold spores float in the air and eventually land in places where they can grow into new mold.

With the use of germicidal UV-C light in air purifiers, you not only trap mold spores, you effectively destroy them, keeping the spores from forming new mold.

UV light is extremely effective at destroying airborne contaminants such as mold spores, but if mold has already taken hold, it will need to be cleaned by direct methods.

Air purifiers can only eliminate the spores floating through the air, they can’t do anything about the mold hiding in walls or underneath carpet.

Another use for UV light is the elimination of viruses and bacteria. While more research and development is needed, it is clear that UV light, when properly utilized, can reduce or even eliminate the amount of viruses and bacteria in the air.

While bacteria can often be trapped by filters, viruses are so small that they literally slip through the gaps. With UV light air purifiers, the viruses are exposed to harmful light, killing them before they escape. This included threats such as Corona Virus Covid-19.


After the air passes through an internal UV Light filter, where all Viruses and Bacteria are removed, it then goes through Pre-filter.

Prefilters mainly used to trap large particles in the air. This strategy, is extremely effective for removing large particles, such as dust, pollen or pet dander and saves other filters from clogging up too fast.


High efficiency particulate air (HEPA) filters are becoming more commonplace in the household market. In the past these filters where used primarily in the clean room and biosafety technology markets, however, today HEPA filters have become a household name as consumer product manufacturers market HEPA filters to
improve home air quality.

Generally, HEPA filters are 99.97% efficient at the 0.3 micron particle size and are therefore very effective on sub­micron particles.

HEPA filters control particulates to protect the product, personnel, and environment or all three. We are using only the highest quality HEPA filters to achieve the desired Air Filtration effect.

High-efficiency HEPA filters used by Castellex effectively trap hazardous bacteria and viruses to provide full protection. Although an individual virus particle ranges in size from 0.005 to 0.1 micron, larger viruses such as CORONAVIRUS covid-19 only survive to travel through the air as part of larger particles (0.3 micron or larger), for example, attached to mucous particles. Because it is difficult to disperse or aerosolize single viral particles and because
of the particle collection mechanisms of HEPA filters, particles larger and smaller than a filter’s most penetrating size are collected with greater efficiency.


This is an advanced type of filter that uses highly-porous charcoal to trap gases like odors or smoke. Because of all the pores, activated charcoal has a massive surface space, which can be utilized to hold large amounts of gases. The key function of carbon filter technology in smoke removal. This type of filter is an absorbent filter that will retain certain vapors passing through it to control odors or chemical smells.
