Keep reading to know more about the most efficient air purifiers and how they help improve our health.

What Do Air Purifiers Do?

An air purifier helps capture airborne pollutants and improves the air quality in your room. The air purifier filters airborne particles like pollen, pet dander, dust mites, paint fumes, and smoke particles. These particles can cause health issues in people with seasonal allergies and affect respiratory health.

The main function of an air purifier is to clean air that could be contaminated and eliminate pollutants.

How Does an Air Purifier Improve Indoor Air Quality?

An air purifier is a tool that purifies the air by removing allergens and pollutants that we can’t see with our eyes. Air purifiers use advanced air cleaning technologies and filtration to achieve this. The airborne particles that are removed from the air depend on the type of air purifier and filter used.

While other purifier models can eliminate harmful airborne particles without first screening them, some air purifiers have filters designed to trap air pollutants as air passes through them. They have fans that pull air in and then release it back into the room. They even have an additional filter.

If you’re considering using an air purifier, you should first learn how it works because each is different. The particles removed depend on the types of filters used. Air purifiers work in the following ways;

 HEPA Air Purifiers

This is a type of air purifier that captures harmful particles using a HEPA filter. The filter draws air into its dense filter, trapping particles. This prevents them from getting back into the room. It can trap particles as small as 0.033 m.


An ioniser is a device that removes air pollutants using an electrical charge. It works in two ways:

  • Releasing into the atmosphere negatively charged ions that stick to pollutants. This bond causes these air pollutants to stick to nearby surfaces and fall to the ground.
  • Pollutants are drawn through the device and collected on charged metal plates or rods. They work the same way as air filters. However, contaminants stick to the material’s surface, and the plates must be cleaned.

Activated Carbon Filters

These air purifiers use activated carbon filters to capture particles. An activated carbon filter works by getting rid of bad smells from your home. This filter also gets rid of other gaseous pollutants like VOCs (volatile organic compounds). Unlike the HEPA filter, this type of filter can only remove chemical vapors.

UV Light Air Purifiers

They work by breaking down pollutants. This air-purifying method releases harmless radiation through a light inside the device. The UV light kills bacteria and viruses as they move through the purifier. UV light breaks down allergens that might trigger allergies, making them harmless to human health.

What Are the Air Purifier Benefits to Your Health?

You may already know that air purifiers are intended to improve air quality, but you may still consider buying one. An air purifier can remove different types of pollutants that can affect your health. An air purifier has more benefits than cleaning your indoor air. Let’s take a look;

They Reduce Allergies

Allergies can easily lead to sickness. The main causes of allergies are exposure to dust mites, pet dander, and airborne allergens. Air purifiers get rid of chemicals from your indoor air. These chemicals can trigger allergies and other health issues.

This is important because regular housecleaning won’t get rid of all allergens. At least 99% of airborne particles are as small as 0.3 microns. The Air purifier removes all of them thanks to the presence of a HEPA filter. It removes most particles that might cause seasonal allergies.

Improve Respiratory Health

Air purifiers can assist in removing the microbes that cause allergies, asthma, and other respiratory diseases. Breathing in polluted air irritates the lungs and throat. You risk getting Chronic obstructive pulmonary disease, or COPD when you do not breathe clean air for a long time.

Improving your air quality gives you healthy lungs. Over 99.99% of allergens can be filtered naturally by HEPA filters. You can get rid of bad smells and airborne pollutants by buying an air purifier with a carbon filter. Having an air purifier at your home helps you breathe healthier air.

Gets Rid of Bad Smells

Buying an air purifier could be a solution if your home or the area around it smells. Cooking, water damage, and flooding can easily cause bad smells to fill the air inside your home.

If water damage isn’t repaired, it can lead to the growth of mold. With the help of an effective air purifier, you can breathe in clean air that has been filtered to remove mold spores and bad smells. There is also the risk of dementia in elderly adults exposed to tobacco smoke.

Removes Harmful Chemicals

Cleaning detergents and household items like mattresses have different volatile organic compounds. While some are safe to handle, those that are airborne are harmful to your health.

The symptoms can itch the eyes and throat. Many air purifiers have activated carbon filters that trap these chemicals. They also get rid of bad smells and leave your house with clean air and fresh smell. A purifier improves your indoor air quality.

Removes Pet Hair

Children and other family members risk breathing particulate-filled air because pets shed, produce pet dander, and emit odors. The condition may become better if the pet is regularly groomed.

Your body may develop allergies and other health issues years down the road if the suspended air gets inside of you. Buying a quality air purifier to remove dangerous particles is one of the things you need to do to live better with your pets.

Improve Your Sleep Quality

The benefits of air purifiers go beyond just purifying indoor air. People have compared the sound that air purifiers make to soothing natural sounds like ocean waves and mountain winds. You become more relaxed and can sleep more easily thanks to these sounds.

To allow your body to concentrate on sleeping, get an air purifier with a HEPA filter. This is especially true for people who have allergies or breathing problems. Additionally, their sound can create the right white noise to put your mind to sleep and help you avoid distractions.

Lower Risks of Diabetes

Air pollution may be a factor in getting diabetes. You can use a portable air purifier to remove these fine particles from your home or office. This prevents you from being exposed and can lower your diabetes risk.

Lowers Blood Pressure

Maintaining your blood pressure is one of the benefits of breathing clean air. Many studies have shown that reducing exposure to harmful particles will lower blood pressure. You can either use an air purifier or wear a face mask.

Additionally, studies show that air pollution increases the chances of high blood pressure and stroke.

Improves Awareness

Studies suggest that air pollution affects a person’s level of concentration. In addition to reducing productivity, poor air quality can affect your awareness. The effect gets worse if you do not have enough sleep. Additionally, cleaner air can reduce stress and improve mood.

Prevents Airborne Diseases

An air purifier reduces the spread of allergens that might make people sick. There are two ways they can do this. 

  • The EPA has found that HEPA filters successfully capture many viral particles, including those linked to COVID-19.
  • There are UV-C lamps in many cleaners as well. These target germs, bacteria, viruses, and mold spores and prevent them from multiplying. 

Improve Your Lifestyle

Getting an air purifier for your home or business is a great place to start if you want to live a healthier lifestyle. You can choose the best air filter with various settings and features. An air purifier has many other benefits and ensures you breathe fresh air.

It can assist those with compromised immune systems. Pregnant women can also benefit from breathing fresh air due to the reduced risk of certain illnesses spreading to newborns.

Reduce Stress

Studies have shown that pollutants increase your stress level. Air purifiers play a major role in reducing stress by cleaning the air and getting rid of toxins. This also improves your mental health.

It kills Germs and Bacteria.

More than 1’000 different types of bacteria are present in the air you breathe. Consider the fact that whenever someone sneezes while they are sick, germs are spread through the air and are inhaled by others. By getting rid of these germs, air purifiers lower your risk of getting sick.

Act as Mosquito Repellant

The benefits of air purifiers have changed over time due to technological advancement. Some air purifiers work wonders at keeping mosquitoes away. Even in the summer and bug-buzzing seasons, you will sleep soundly. You will be breathing in the fresh air and dreaming simultaneously.

Improves Your Skin

When air purifiers remove and kill pollutants from the indoor air, your skin is protected from toxins that cause itchiness, acne, and other uncomfortable skin conditions. As a result, your skin will age more slowly and get rid of acne. Air purifiers protect your skin from contact with germs.

Prevents The Effects of Mold Spores

Excess moisture causes molds to appear on the walls. These molds can cause health problems and infections. Air purifiers help deal with the mold spores produced without damaging your walls.

Air purifiers that come with HEPA filters and activated carbon can get rid of airborne spores. The air purifiers also deal with the mold odor produced thanks to the carbon filters.

Helps Deal With Headaches

The sinus headache is the most common type of headache. This results from airborne allergens causing pain in the region around the head. When the air purifier runs, it kills these allergens. This prevents you from inhaling them and getting a headache.

Alternative Methods of Removing Indoor Air Pollutants

There are other methods of reducing air pollution levels in your home. Indoor pollutants have harmful effects on your health. Here are ways to deal with them.

Open Your Windows

It is the easiest thing you can do to enhance the air quality inside your home. To reduce the buildup of dust mites in your indoor air, open your windows for ten minutes daily. Consider sleeping with open windows to ensure a supply of clean air at night. Open windows whenever you can while cleaning; the fresh air will enhance the final impression of cleanliness.

Keep Pets Groomed

If you have central AC, you already have access to a whole-house air filtration system. Air purifiers and conditioners work in similar ways It removes air from your home, cools and pumps it back in. Most systems have a filter that needs to be replaced frequently; while doing its job, it can trap particles.

It will be better the more you change it. Know your AC system type and the manufacturer’s suggested HVAC filters replacement schedule.

Air Out New Furniture

The VOC emissions from a new sofa or armchair will increase initially before decreasing. Air out your home as much as possible to let VOCs escape to reduce the harm to your indoor air.

For the first few months, keep the windows open most of the day in that room or store it in your garage for a few days. You can also look for used textiles and furniture, which are much more likely to have off-gassed any unsavory toxins.

Use Environmentally Friendly Cleaners

Consider buying cleaning supplies with a low VOC content. According to studies, the ingredients in common cleaning products are harmful to humans. Learning how to make your cleaning solutions, body soap, and other beauty products from scratch in an eco-friendly manner will help reduce indoor air pollutants.


Apart from giving you clean air, air purifiers benefits are many. They have different functions, like trapping airborne particles and dust particles. People with air purifiers lead a much healthier life. This article covers all you need to know about air purifiers and their Role in improving your health.
