10 Surprising Advantages of Air Purifier

According to EPA (Environmental Protection Agency), indoor air pollution is one of the most environmental dangers we face today. Most people spend around 90 % of their time indoors. Hence, the quality of the air we breath should be a major concern for us. 

Air purifiers are one of the easiest and simplest methods to deal with indoor air pollution. Air purifiers can create a clean and refreshing environment, reducing the chances of respiratory diseases.

In this article, we’ve discussed the advantages and benefits of air purifiers.

Advantages of Air Purifier

1. Cleaner And Healthier Air

The primary objective of an air purifier is to simply clean the surrounding air by removing all the contaminants from it. The air we breathe contains many small particles, gases, and substances that could be harmful to our health. These pollutants affects the air quality and can have adverse health effects, including, respiratory problems, various allergies, headaches ,fatigue, dizziness, eye irritation, skin rashes and throat infection. It may also cause long-term effects like heart diseases & cancer. 
Air purifier uses advanced filtration technology that filters out such harmful substances from the surrounding air, making the air clean and healthy for us.

2. Relieves Asthma Symptoms

According to WHO, more than 339 million people are living with asthma. People with asthma suffer from various problems like breathlessness, coughing, wheezing, sleeplessness, and may also cause fatigue. Allergens like dust mites, cockroach feces, mold spores, pet dander, and pollens cause an allergic reaction.
pollens from trees & grass generally flow along with the air and can enter your house or stick to your clothes, which may cause allergy. So, it is better to stay inside and close the windows when the pollen count is high. Dust mites are microscopic critters that live on your mattresses, fabrics, and carpets, which are the most common indoor allergens for people suffering from asthma. Vacuuming and cleaning your floors, mattress, carpets, and beddings are the best solution to avoid dust mites. If you have pets, get tested to see if they are causing your problem. Because sometimes pet dander (extremely tiny pieces of skin that a pet sheds) can aggravate asthma symptoms in some people.
These allergens aren’t the only thing that makes allergic asthma worse. Irritants like perfumes, smoke from tobacco, candles, and incense, dusty room, or strong chemical odors may still trigger asthma attacks.
Air purifiers can help you in keeping your asthma in control by eliminating these allergens, irritants, and other harmful substances. Most air purifiers are equipped with HEPA filters, which are capable of trapping pollen, dust mites, mold spores, pet dander, and irritants. Air purifiers are considered to be one of the most effective measures to prevent asthma attacks and stay healthy.

3. Beneficial For Skin

Pollutants, chemical toxins, and dust can damage your skin. it can also cause skin rashes, irritation, dryness, or even acne. By trapping these harmful toxins and pollutants, an air purifier not only prevents you from the adverse effects, but also slow down’s the aging process. You don’t believe it ? Air in the atmosphere contains various particles that come from dust, pollen, gases and what not. These particles when settle on your skin can have negative impact on skin’s collagen, a protein that gives skin its structure, suppleness & stretch. These pollutants cause collagen to break and make your skin sag. Since an air purifier traps these pollutants and toxins, it helps you slow down aging process.

4. Reduces Stress

According to a study, air pollutants (Both indoor & outdoor pollutants) increase the stress levels. Longer exposure to such pollutants is associated with high blood pressure, worse insulin response, and molecular stress on body tissues, which can, over time, increase the risk of heart diseases, diabetes & other problem.
Air purifier improves air quality and keeps the surrounding air clean by eliminating these pollutants. Such clean and cool air can have a soothing effect on the body, thus reducing stress.

5. No More Unpleasant Smell & Odors

Apart from keeping the air clean, an air purifier also helps to neutralize bad odors from the surrounding. Molds, outdoor gases, volatilized chemical compounds (VOCs), cigarette smoke, pet odor, garbage, and cooking smell lead to unpleasant & pungent smell. Most air purifiers come with activated carbon technology, which removes the molecules that create the smell in your home, thus maintaining a fresh environment.

6. Removes Harmful Radon Gas

Radon is a naturally occurring radioactive gas. It is odorless, tasteless, invisible, and emits from soil, rock, and water. Long-term exposure to radon gas can have a fatal effect on your health and can also cause cancer.
you get exposed to radon when you breathe it. Radon generally accumulates in your home through ground or cracks. once it enters the crack, it starts building up and starts increasing.
You can reduce the risk of radon pollution by using an air purifier. HEPA and carbon activated filters can trap radon gas and keep you safe from its harmful effects.

7. Seasonal Allergy Control

For people suffering from a seasonal allergy or hay fever, it is extremely important for them to keep their surroundings free from molds, pollens, and other allergic pollutants. These pollutants float on air, stick to surfaces and walls. As we move around the house, we sit, pick up things, sit down, or get up from furniture, we get in contact with the particles, which further can lead to allergies.
Investing in a top-quality air purifier can safeguard you & your family from those harmful pollutants and keep your allergies in control.

8. Helps You Get Rid of Pet Hairs and Dander

If you stay with pets, you will find lots of hair all over your house. Pets usually shed hairs and dander (minute skin particles). These particles constantly keep floating in the air, which puts you and your family member at risk of inhaling them. Inhaling these particles could trigger allergies and cause severe health issues.
An air purifier with a HEPA filter is capable of capturing these minute particles and hairs floating in the air and keep you safe from them.

9. Improves Sleep

Air pollution can increase the chance of poor sleep by 60 %. Indoor pollutants like dust, pollen, and smoke can cause an allergic reaction, which includes skin irritation, cough, sneezing, rashes, headaches, fatigue, and breathlessness and keeps you from getting a good night’s sleep. Air purifiers can improve air quality and decrease the chances of allergies by reducing pollutants. A fresh and clean environment gives you a good night’s sleep.

10. Can improve Life Expectancy

Indoor air contains numerous amount of pollutants that can affect your health. Some of these pollutants are so small that you cannot see them with your naked eyes, and these pollutants keep constantly floating in the air around you. Long term exposure to these pollutants can affect your respiratory and cardiac system.
A quality air purifier will trap these minute pollutants and help you to lead a healthier life.

How Air Purifiers work ?

In simple words, an air purifier sucks indoor air containing pollutants. Then this air passes through multiple filters, which eventually traps dust, allergens, pollen, even small unseen particles, and distribute clean air in your room. This is how an air purifier provides a clean and healthy environment for you.

Types of Air Purifier

Air purifiers come in all sorts of sizes, shapes & colors. Different types of air purifiers use different filters to clean indoor air. And it is very important to know how each of these works. Most air purifiers use HEPA filters, some use activated carbon or UV light. While some advanced air purifiers incorporate multiple types of filters. Let’s have look at them.


Do you know? an average human eye cannot see particles that are smaller than 50 to 60 microns. While an air purifier with a HEPA filter can capture pollutants as small as 0.3 microns, which you can’t see.

> Activated Carbon

Air purifiers with activated carbon filters are capable of removing harmful toxins, smoke and, also unpleasant odors. However, they do not trap dust, pollen, or other pollutants that HEPA filters do. But there are air purifiers, which use both HEPA and activated carbon filters to serve their individual purpose.

> Electrostatic

Electrostatic air purifiers use a static electric charge to trap particles as they pass through air. These charged particles stick to the side of the purifier and are removed from your indoor air. Electrostatic filters are less effective when compared to HEPA filters. Electrostatic filters have a 60-80 % first-pass efficiency rate, while HEPA filters have around 87-99 % first-pass efficiency rate.

> UV Light

UV air purifiers use short wave-ultraviolet light to kill pollutants and micro-organisms like mold, bacteria & viruses in indoor air. Some UV air purifiers emit ozone as a by-product, which is not at all good for human health. Make sure to check this factor, if you are looking forward to buying an air purifier with a UV filter.

> Ozone Generators

Ozone air purifiers are used to remove strong odors. However, ozone air purifiers intentionally emit ozone (O3) and do not remove particulate matter on their own. Exposure to ozone can trigger asthma attacks, can cause cough, chest pain, or breathlessness. Many companies brand ozone purifiers as safe & effective, but we recommend you to avoid them.

Factors to Consider When Buying an Air Purifier

> Filter

In the above section, we’ve already discussed the types of filters. And we can conclude that the HEPA filter is the best choice, as it can trap minute particles with very high precision. Also, look for ”HEPA” or True ”HEPA” filter, avoid air purifier with terms like ”HEPA like” or ”HEPA Type”.

> Room Size

This one’s pretty easy. Firstly measure your room size in which you will be using the air purifier. Then read the specification list & find ”coverage area” in that section to decide whether it is suitable for your room or not. We recommend you to look for a coverage area that is slightly higher than your room size.

> CADR Rating

CADR stands for Clean Air Delivery Rate and it indicates how fast the air purifier functions. It calculates how many cubic feet of air it can filter in one minute. High CADR no indicates an air purifier with a powerful fan.

> Air Change Per Hour (ACH)

Air change rate indicates the no of times per hour an air purifier filters the entire air from the room. A higher ACH means better air quality. The ideal ACH value is 4x, but if there’s an asthma patient in your home, opt for a 5x or 6x rating.

> Noise Level

Air purifiers come with fans and emit noise. To avoid disruptions in your sleep choose an air purifier that is less noisy. Air purifier generating less than 32 dB(A) are considered quiet ones.

> Technologies To Avoid

UV light & ozone generators are harmful to health and can cause respiratory problems. It is best to avoid them.

> Filter replacement & Customer Service

A filter needs to be changed periodically in air purifiers. Depending on the type of filter, room size & brand, the cost of these filters varies accordingly. So keep that in mind before purchasing an air purifier. Second thing is to check filter availability. It is important that these filters are easily available in the market.
Last but not least, check the after-sales service offered by the company. Look for product reviews, check the company’s website to see if they have a support store in your city.

1. Can Air Purifier Prevent Coronavirus?

No, there is no proven evidence, which states that an air purifier can prevent coronavirus. Generally, HEPA filters can capture particles as small as 0.3 microns. However, coronavirus measures 0.06 – 0.14 microns and can easily pass through the HEPA filter.

2. Are Air Purifiers Waste Of money?

No, they are not a waste of money. Air purifiers actually work and can remove 99.97 % of particles in the air using a true HEPA filter which includes dust, pollen, smoke, pet hair & dander, harmful chemicals, and odors.

3. Where Should I Place My Air Purifier?

It’s quite simple. Place it closer to the source of the problem, may it be a kitchen, bedroom, or hall room. Also, keep in mind the coverage area of the air purifier and consider placing it somewhere to get the most out of it. Avoid corners and tight places, keep the air purifier in an open area for maximum effectiveness.

4. Do Air Purifiers Help You Sleep Better?

Yes, they do. Indoor air is full of smoke and minute particles which include, dust, pollen, and allergens. These pollutants can cause irritation, headache, fatigue, and breathlessness, disrupting your sleep. An air purifier is capable of removing all these pollutants and helps you maximize your sleep quality.

5. What Are The Side Effects Of Air Purifier?

Some air purifiers like ozone generators, UV light, and ionizers emit ozone. Exposure to ozone can trigger an asthmatic reaction and can damage the lungs causing respiratory problems.

6. Do Air Purifiers Remove CO2?

No, air purifiers don’t remove CO2. Air purifiers remove pollutants from the air. To reduce CO2, we recommend you to keep a prayer plant in your home.

7. Is Air Purifier An Air Conditioner?

The air conditioner works to remove heat and humidity from a room. In a limited sense, they do filter out some impurities, but its filtration is nowhere near that of an air purifier.

8. How Long Does It Take An Air Purifier To Clean A Room?

It depends on the following factors :

  1. Room Size
  2. Filter Used
  3. CADR Rating
  4. Level of Contamination
