Air Purification Systems Market Types and Functions
Air Purification Market value was at USD 5060.0 Million in 2018 and is expected to grow by USD 8997.74 Million by 2023 at the CAGR of about 12.2%. The automotive industry has the largest share for help developing the market.
Introduction:
An air purifier or air cleaner is a device that removes pollutants from the air in a room to improve indoor air quality. These devices are generally marketed as being beneficial for people with allergies and asthmatics, as well as for reducing or eliminating tobacco smoke. Commercial air purifiers are manufactured in the form of small independent units or larger units that can be connected to an air handling unit or heating, ventilation and air conditioning (HVAC) unit in industries medical, industrial and commercial. Air purifiers can also be used in the industry to remove impurities from the air before treatment. Alternating pressure absorbers or other adsorption techniques are generally used for this purpose. One of the main advantages of air purifiers is that they remove dirt particles that are bare insight.
Air filtration technology:
There are two types of air purifiers, active and passive. Active air purifiers use ionization to purify the air. This means that they release negatively charged ions in the ambient air, thus causing the adherence of contaminants to the surfaces. During the work, their operation poses a problem: they can release Ozone as a by-product. Passive air cleaning units, on the other hand, use air filters to remove contaminants. They are more efficient because all dust and particles are permanently removed from the air and collected in the filters.
Types and functions of air filters:
To be effective, air purifiers need a multi-stage air filtration system. A multi-stage air filter product generally has three types of filters.
Prefilter:
The prefilter acts as the first line of defense and removes PM10 contaminants such as dust, smoke, hair, pet dander, large pollen, etc. The prefilter also helps extend the life of the secondary filter by not allowing it to drown before. Due to the difference between the type of contamination and this one, the prefilter is not used in air purifiers in the United States and Europe; however, it is becoming of paramount importance in countries such as India and China.
Charcoal filters:
This filter is used to remove volatile organic compounds (VOCs), gaseous substances, and air odors. Some brands use their own patented filters instead of these filters, such as the HiSiv filter used by Honeywell air purifiers.
Filters in-car air purifiers
Cars usually have a prefilter installed in their fan, so car air purifiers can only operate with HEPA and charcoal filters.
The best home air purification systems available
HEPA filtration
- HEPA (high-efficiency particulate air) is a common way of filtering air particles. This technology can trap approximately 99.97% of particles larger than 0.3 microns, including dust, pollen, viruses, mold, and bacteria.
- The main advantage of HEPA air purifiers is that they do not cause by-products and do not damage Ozone.
- What are the HEPA filters made of? They are built with fine fiber-like materials that repeatedly bend over themselves to create a series of barriers that require the passage of air.
- When air enters the air, HEPA filters stop and retain all airborne contaminants. Only fresh air comes from the other side.
- Although HEPA filters are the most effective for trapping particles, sometimes they need to be replaced. Note that the types of air purifiers equipped with HEPA filters eliminate odors, chemicals, and gases.
Negative ionization
- Negative ionization is one of the most common types of air purifiers and uses the ionic emission process to purify the air.
- These air purifiers take into account that airborne particles contain positively or negatively charged ions. These devices can magnetically attract airborne particles and remove them from the air. Common things removed include pollen and dust.
Activated carbon filtration
- Activated carbon technology is another type of air filter. It uses carbon (also called carbon) that is extremely porous to absorb airborne particles.
- With chemical bonds and high absorption rates, activated carbon is very effective in trapping the elements that HEPA eliminates badly. In particular, they know how to neutralize gases, tobacco smoke, odors, and chemical emissions.
UV illumination
- UV technology is a popular option and is often used with other types of air purification systems.
- UV rays do not use a physical filter to aspirate and trap harmful particles in the air but use a special technology that perfectly eliminates germs, viruses, and bacteria.
- UV technology works by using a lamp installed in an air purifier. When the microorganisms pass in front of the UV lamp, the structure of the DNA separates. The resulting cell damage kills microorganisms.
Ozone generation
- Ozone air purifiers produce Ozone to clean contaminated air.
- Although many people think that these types of air purifiers are safe for indoor air quality control, their use poses a number of problems.
