Are air purifier effective?
The answer to this is simply yes air purifiers are adequate, although there are some on the market that aren’t exactly worth your money, and would do little to clean up your air. The qualities of a proper air purifier would be discussed.
A good air cleaner should contain a true HEPA filter, which is designed to filter 99.97% of particles as small as 0.3 microns, removing pet dander, dust, allergens, smoke, and odor from the air, preventing allergic reactions.
The working principle of air purifier
A good air purifier generally should contain at least three stages of filtration, i.e., a pre-filter, a HEPA filter, and an activated carbon filter. The pre-filter helps in removing large particles from the air, therefore allowing only tiny microns particles go through which is then captured by the HEPA (high-efficiency particulate air) filter.
The activated carbon filter is a porous material that can absorb molecules of volatile chemicals, not affecting larger particles. It is simply a process of changing contaminants from gaseous to solid state, majorly dealing with smells and odors in the air.
In basics, the pre-filter removes the large particles in the atmosphere, while the carbon filter absorbs the molecule responsible for that foul smell, and the HEPA filter removes 99.97% of particles as small as 0.3 microns in the atmosphere.

Different types of air purifiers
By types, we mean the different kinds of technologies by which the air purifiers works. There are five major types of air purifiers out there, with several advantages, depending on your preference and the condition of your atmosphere you should select the most suitable for you.
Sometimes manufacturers combine more than one of these technologies in a single device for better performance and efficiency. These technologies are
1) HEPA technology
The HEPA type air purifier, makes use of a specially designed type of filter in trapping Allergens. It must meet the minimum qualification of trapping at least 99.97% of particles less than 0.3 microns. Most of these particles caught in the HEPA filter cannot be seen by the human eye, due to their size, and are they are safest to use due to their ability to trap the molds or bacterial, not generating ozone or another type of harmful byproduct.
The HEPA filters are mostly designed with foam, cotton, fiber-like or any other active particle trapping material, effectively creating a surface for air to be pushed through by a fan. On the other side of the filter, the air comes out clean, free from all allergens and particles, while the device repeats this process over and over again, effectively reducing contamination in the atmosphere each time.
Eventually, the filter would accumulate more than it was built for, and depending on the design, a need for it to be cleaned or replaced would arise. An average HEPA filter should last about 2 to 4 years.
There are three primary mechanisms by which the filter captures particulates, firstly particles when forced in by the fan could come in contact with the trapping material, and get stuck to it. This is called an interception. Also, another mechanism called impaction occurs as the name implies when particles collide with the filter material, embedding into them. The last is diffusion which occurs with gas molecules when they clash with the particle trapping materials, making them move slower and either undergo interception or impaction.
Although these HEPA filters are very active, they are helpless when faced with odors, chemicals or gases, which brings us to our second type of air purifier.
2) Activated carbon technology
The specialty of this type of air purifier is in dealing with odors and smells in the atmosphere. It contains a form of carbon that is very porous and has a large surface that helps in efficient absorption. They comprise of several molecular sized pores with high absorbent ability and chemical bonding tendencies, making it effective for capturing chemical pollutants and gases which are then held by the filter.
This type of purifier is best for people with high chemical sensitivity, preventing against chemicals like formaldehyde that is mostly released by new plastics and furniture. The best air purifier for formaldehyde make the environment more conducive especially for those with asthmas. For most patients, pet dander, dust, and pollen are the major particles irritating, but for some gases (VOCs especially) acts as riggers too.
These filters greatly tackle volatile organic compounds (VOCs) like smog, ozone, cooking smoke, pets, tobacco smoke, could be healthy for anyone generally, not just asthmatic patients, but do very little against removing particulate allergens.
3) UV (ultraviolent) Technology
The UV technology air purifier specializes in killing germs like bacteria and viruses; it makes use of a UV lamp that emits ultraviolet rays, effectively destroying microorganisms in its range. It is mostly used alongside other filters, especially the particulate filter type and can convert molecules of oxygen in the atmosphere to ozone and hydroxyl.
While the air purifier with UV technology for germs works wonders against bacteria and viruses, you should be careful to note that it doesn’t generate ozone. This is so because ozone isn’t needed for cleaning and can be harmful to pollutants. Therefore a functional unit that gets air particles filtered using the UV technology should minimize or eliminate ozone.
How effective the device depends on the wattage of the UV light and the duration of exposure to the light, with time the UV bulb deteriorates just like every other electrical device, therefore it should be monitored and replaced accordingly. Generally, this air purifier type is best used with a filter system placed ahead of the lamp. This prevents microorganisms from forming a shading layer on the UV bulb that could reduce the impact of the rays it emits, which is why most manufacturers combine this technology alongside the HEPA and carbon filter.
4) Negative Ion
They employ a technology that releases ions into the atmosphere in order to clean the air. Ions are either positively or negatively charged, becoming so by gaining or losing an electron. The Negative ions are atoms that have gained an electron, and when they are released into the atmosphere, they can magnetically attract most airborne particles that are neutrally or positively charged like pollens and dust. This process goes on till the new particles (negative ions and contaminants in the atmosphere), becomes too heavy to remain in the atmosphere, eventually dropping to the floor, furniture or a window.
Air purifiers that employ this technology are generally not as effective as other types. This is so because the negative ion merely holds down the allergens temporarily and it could be released back into the atmosphere eventually. They don’t absorb and retain the pollutants as other filters and technology do.
5) Ozone generator
They operate by releasing a gas called ozone, which is meant to work by inhibiting the growth of biological components in the atmosphere. However, this is most unlikely, because studies have shown that the ozone level needed to deal with allergens effectively, are significantly higher than public standards and cannot be used by the device.
Ozone is unsafe and not effective in cleaning the air, and exposure to it might cause irritations and even damages to the lung while elevating asthma symptoms. Ozone generating devices do not clean the air, and the ones coupled with UV technology just ends up masking instead of reducing the contaminant level.
