We provided you a list of best air purifiers in 2021. But the question is, why do you need to buy an air purifier? Do these air cleaners work effectively to clean our indoor environment? Or do you need it while sitting at home or sleeping in your bedroom?

Good air quality is essential for our health, like food and water. I am sure your answer will be yes if I ask you, do you invest in time and money in diet and exercise? Similarly, we need to invest in cleaning our air to save ourselves from numerous diseases.

With the population growth and advancement in technology and the industrial sector, the polluted air is impacting all of us. According to the World Health Organization (WHO), every year, 4.2 million people are dying because of polluted air.

Now I want to grab your attention to the point of how air purifiers clean our air? Why we need the help these air cleaning machines.

How does Air Purifier work?

Air purifiers consist of multiple air filters made by fiber, paper, and mesh. These filters help to circulate air through intake and outlet systems so they can remove airborne particles like cigarettes, led, and arsenic from the air.

Use of Activated Carbon Filter

If you look for the best air purifier in the market 2021, you will find out that many air cleaners use Activated Carbon Filters. These filters use carbon in granular or powdered form to act as an absorbent and captures particles like dust, pollen, and odors.

These filters are good to remove hazardous compounds, but their efficiency is restricted to gaseous pollutants like VOCs and radon.

You may be thinking about how you can clean air by using a chemical? Now let me explain how Activated carbon Filter works. You need to put activated carbon in the filter of air purifiers like HEPA filter.

Polluted air enters in the filtration system by intake grills of the air cleaner, and passes through the active carbon. The small absorbent pores start the absorption process and then air leaves the filter by outlet grills. If you enable the HEPA filter with Activated Carbon Filter, then it will help to capture the large airborne particles like dust, lint, pet hair, and mold spores.

Activated Carbon Filter is highly effective to clean the polluted air. If your filter is more activated than then the capacity of removing impurity, filter life and absorbing pollution will increase. The combination of carbon filter with magnesium dioxide and copper oxide helps to remove harmful pollutants from the air like monoxide and ethylene oxide and bacteria.

True HEPA Filter

In our list of best air purifiers in 2021, you may be noticed that most of the air purifiers used the term True HEPA Filter. All modern air cleaner brands are using Ture HEPA Filter to enhance the performance of their product.

Now we will talk about widely used High-Efficiency Particulate Arresting (HEPA) filter in air purifiers. Before buying any air cleaner, we will recommend you to focus on those air purifiers having certified HEPA filter that can remove 99.97% airborne particles as small as 0.3 microns.

We are unable to visually see anything less than 10 microns

When the polluted air passes, these filters capture the larger particles and the smaller particles which try to pass through fiber trap by the edges of the fiber. Now the smallest particles (0.3 microns) have free random movement destroy by diffusion.

The True HEPA filters are different from each other because of their fiber density and quality. You will find many terms in the market like HEPA-type or HEPA-like but always go for Ture HEPA Filter because only this filter can capture the polluted particles size of 0.3 microns.

UV-C Light Filter

The UV-C light filter is an air sanitizer commonly used in high-end and affordable air filters to destroy the germs, including mold spores, bacteria, and viruses. The True HEPA filter works with a UV-C light filter to collect the bacteria and viruses and kill them.

You cannot see UV-C light by the naked eye. It uses electromagnetic radiation effectively to prevent the DNA reproduction of the microscopic particles like germs from the air that cause many diseases. Then with the help of True HEPA filter, it removes other allergens like dust, pollen, and pet dander.

If you think that UV-C light is harmful to humans, then there is no need to be a worry. It usually causes no harm plus the light bulb is placed inside of the air purifier so you will not be exposed to ultraviolet rays.

The problem form UV-C light is that it emits ozone which is irritating for asthma, breathing issues, and many other allergens. Most air cleaners introduced turn off and on function if it causes breathing problems. It is necessary for you to buy certified air purifiers.

Ionizer

Some air purifiers use an ionizer instead of True HEPA filter to kill germs by high voltage electricity to charge the air molecules. The airborne particles are as small as 0.1 microns attract to the negative ions and fall on charge collector.

The air ionizer plays an effective part in cleaning air with the replacement of the filter. In the air purification process, it emits ionized air which can be harmful to lungs with unwanted ozone. But the good news is there is a turn-off, and on function if ionize air or ozone start irritating for asthma and other allergens.

PlasmaWave Filter

In PlasmaWave filtration, the air in the plasma state strike water to release the oxygen and hydrogen. Oxygen and hydrogen create unstable molecules, hydroxyl radicals, by taking atoms from airborne pollutants like germs, odors, bacteria, and volatile organic compounds (VOCs) and destroy them.

PLasmaWave is one of the core filtration processes in air cleaners. There is no ozone emission in this process so we can say that the PlasmaWave filter is not irritating for asthma and allergens. But we will still recommend you to purchase only CARB certified air purifiers.
