NBC Air Filtration

Make your Panic Room safer by filling it with clean air

     A safe (panic) room, bunker, or bomb shelter only goes part of the way to protecting your family and possessions. In the event of a nuclear, biological, or chemical attack, you need to be able to control the environment inside your protected space. Castellex NBC fallout shelter ventilation systems are built to give maximum peace of mind. They will operate efficiently in critical situations, and provide permanent protection for everyday installations such as homes in areas with a high allergen or pollution count.

     Air filtering systems clean the contaminated air and make it clean and fresh. If cleans typically about 99.9% of particles in the air in which it is placed. They are commonly marketed as being beneficial to sufferers of asthma and allergies. It claims to remove even tobacco smoke or smoke produced from fireplaces.

     Commercial air filtering systems are made as either small units that stand-alone or larger groups that can be attached to an AHU (air handler unit) or an HVAC that can be found in industrial and commercial industries.

     Air filters depending upon the size can be used for the entire house or a single room. Air purifiers are made of many different sizes and types. The most common one seen is the one with a HEPA filter. People purchase these air filters to purify their home or office air. There are a lot of air filters available in the market which work differently.

 Types of air filters:

1. HEPA filters. The HEPA filter is the one that is commonly seen in households. It uses a cloth filter that traps about 99.9% of dirt particles that are .3 microns or larger and uses a fan to circulate air throughout the machine. HEPA filters are effective in removing any harmful dust particles in the air and make the air cleaner. The filter can be replaced and depends upon where the or purifier has been placed. It is a very effective unit but uses a lot of energy.


2. Carbon filters. This type of air purifier is very effective in cleaning dust and odours, and it is the most sold air purifier after HEPA filters. Carbon air filter contains small pores that are very absorbent. As the odour particles pass through the purifier, it gets attached to the carbon which absorbs it. This air purifier does not work against allergens or micro-organisms and thus not very effective for people who have asthma or sensitive people.

3. Ozone filters. Ozone is a reactive oxidant that can destroy some chemicals and bacteria. When it reacts with some substances in the air, those substances are broken down into materials that are pollutants. An Ozone purifier fights those pollutants. It is also very effective in fighting odours, but, it also does not work in killing allergens.

4. Ionic filters. This type of filtering system ionises the air, causing particles to gain either a positive or negative charge. The ionic air purifier has a collection of plates that contain an opposite charge from the air particles; therefore, the particles are attracted to the plates. The charged particles will attract other particles with the opposite charge to them. An ionic air purifier can remove very fine particles in the air like dust particles, even from several feet away, but it does not work on odours or kill germs.

5. UV Light Filters. 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, mould and mildew.

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

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

UV light is extremely effective at destroying airborne contaminants such as mould spores, but if mould 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 mould hiding in walls or underneath the carpet.

Another use of 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 number 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 - Covid19.

 It is quite challenging to choose the perfect air purifier, but, doing complete research on the product surely helps.
