Unwinding the Complexities: Air Purifier Technology

Air purifier technologies are not necessarily new to the human lifestyle, since patrons of these innovative devices are reaping the benefits both in the workplace and at home. Now that pollution is present practically anywhere, having an air purifier is evolving to be a necessity in order to keep the air people are breathing safer, thus healthier.

However, as the technology is being reinvented over time, most people are uninformed about how this cutting-edge design actually works. Knowing the machineries that make up air purifiers can help one better appreciate its avant-garde design, and its composition that makes it effective.

Filter Technology

There are a variety of types for air purifiers, and each present unique pros and cons. They are distinguished in types, decided by the filtering technology it uses.

The mostly used type today is called HEPA (High Efficiency Particulate Air) Purifiers. Many studies in the industry suggest that it is the best type of air purifier, since it removes up to 99.97% of particles that pass through it. In addition to being the best air purifier for allergies, as well as being used worldwide in medical cleaning rooms, advanced HEPA filters are used by the nuclear power industry because of its efficiency.

Another type of air purifier is the Ionizing Purifier. This type of purifier makes use of a method called corona discharge in order to generate ions.The corona discharge’s small yet intense electrical field can make molecules either positively or negatively charged. Although it only removes 30% of particles in the air, the advantage is that it does not need air filter replacement.

There are also Ozone Generators that alter oxygen molecules into ozone, deodorizing and disinfecting the air around it, making it free from bacteria and other microorganisms.

Complementary Technologies

Since filter processes is not limited to a single stage, there are other technologies that manufacturers use to improve their product in terms of performance. One good example is the pre-filter. Even though HEPA filters have a large number of pleats to maximize their surface area, they can fill up quickly if larger particles are not pre-filtered out. A pre-filter captures the largest particles before they reach the more expensive HEPA filter. Most of the particles in air are large particles like dander and dust, not tiny ones like pollens and microbes.

Elements like activated carbon, zeolite, or potassium permanganate are added to air purifier filters to increase efficiency to the filtering system. These elements work to absorb smoke, gases, chemicals, and odors that are present in the air.

Ultraviolet light (UV) technology is key to neutralizing viruses and bacteria that accumulate in air purifier filters. It is important to use the UV technology in combination with HEPA air filters and possibly activated carbon.

Assessing the best Technology that fits

The best kind of purifier actually depends on the need of the aspiring user. As these technologies are continually being improved, people may have a hard time assessing what they need.

It boils down to various factors that need to be considered.

Atop the list is checking for performance. It is advisable to look for a unit that removes a high amount of particles from the air, including smaller-sized pieces. The next thing to consider is the air volume capacity of the device. It is best to look for a unit that fits your room size so it would not be a problem on your spacing.

Since air purifiers also differ in the type of molecules they filter, it is best to evaluate what particular substances to be removed. Purifiers can filter smoke, germs, bacteria, and other microorganisms in the air.
