What is an Air Purifier?

Just like water and food, air is also essential for our survival. While most of us invest quite a lot in our diets, we often tend to ignore the air that we breathe in.  

Without a doubt, there are more pollutants present in the air now than there have been in previous years. Pollutants from our cars and industries impact all of us globally. In fact, surveys suggest that toxic pollutants affect over 200 million people worldwide. It’s a known fact that such pollutants can have an adverse effect on health and this is where air purifiers come into play.

Mold and dust commonly collect inside homes, leading to various respiratory issues like allergies and asthma. Air purifiers, however, remove the toxins from houses along with airborne viruses and bacteria. As a result, it improves breathing which, in turn, benefits your overall health.  

Benefits of Investing in a Great Air Purifier

An air purifier is one of the most essential appliances in every household and office space. This appliance makes our lives more comfortable and reduces irritation by improving indoor air quality.

Because of their role as an air cleaner, air purifiers also play a massive role in the health and safety of ourselves and our children. They make spaces safer for people with respiratory conditions such as asthma as they clean and purify the air we breathe by removing air contaminants.

But are there any alternatives that serve the same purpose? Is an air purifier worth the investment? Below are some of the benefits of an air purifier.

As mentioned above, air purifiers aid in removing air pollutants. In particular, they are useful for people suffering from allergies and asthma. Plus, they help get rid of second-hand smoke as well and are suitable for both residential and commercial environments. Air purifiers have other benefits too including:

Eliminate Allergens Floating Around in The Air

When you inhale dust, pet dander, pollen, or any other airborne allergen, the body tends to produce an allergy antibody.

Allergic reactions soon follow, ranging from mild symptoms such as sneezing and coughing to extreme ones like an inability to breathe.

An air purifier can help avoid this type of reaction. Air purifiers have filters that trap these allergens as the air enters your home. Others use UV rays to kill germs and viruses already floating inside the house, offering you protection throughout.

Extract Airborne Asbestos Particles

Asbestos particles are one of the most dangerous forms of indoor air pollution. Despite being known for causing mesothelioma, deadly cancer that affects the breathing system, it’s still used in various products today. Air purifiers work to remove this harmful air pollutant, thus protecting you and your family from potentially dangerous diseases.

Reduce CO2 Levels in Your Home

Too much carbon dioxide, which can be a problem when confined in a space without plants, open windows, or ventilation to circulate oxygen, can be dangerous. High levels of carbon dioxide can cause headaches, shortness of breath, weakness, dizziness, loss of mental abilities, unconsciousness, nausea, increased heart rate, and high blood pressure. However, certain air purifiers work to eliminate excess carbon dioxide. Some are fitted with an activated carbon filter that neutralizes the airborne contaminants.

Filter Outside Fumes & Pollutants From The Air Entering Your Home

The air entering our houses will inevitably be filled with impurities and contaminants due to rampant air pollution. This outdoor air could be dangerous for the people living inside, especially children under the age of five. The polluted air could cause respiratory illnesses and a wide range of other complications.

However, an air purifier in your house will guarantee that the incoming air is clean. Certain purifiers with a HEPA filter work to trap pollutants as small as 0.3 microns in size. Therefore, you’re sure to breathe safely even if you live in a polluted urban space.

Neutralize Unpleasant Odors

There are many different types of odors that can be felt in an indoor space, including aerosol sprays, paint, upholstered furniture, air fresheners, and cigarette smoke. The smell of cooking oil or spices at home can also be uncomfortable. An air purifier, specifically the ones fitted with a carbon activated filter, can help you get rid of these odors. They effectively trap odors, relieving you from the discomfort. However, it’s worth noting that such purifiers don’t trap any particles or allergens.

Reduce the Spread of Airborne Diseases in Indoor Spaces

It’s very easy for the flu to spread throughout a household. But air purifiers can help reduce this risk. Their filters can trap these pathogens, effectively cleaning the air and protecting the rest of the household.

They Make Breathing Easier

While clean air is quite important for good life quality, it becomes essential if you’re a victim of allergies or asthma. Even if the environment seems to be clean, there can be invisible particles present like dust mites, pet dander, and mold, which aggravate allergy sensitivities. By opting for the right purifier, you can filter out most of them, enabling you to breathe easier.

Cook With Ease

In houses with gas burners, cooking releases an excessive amount of carbon monoxide, nitrogen dioxide, and other fine particles in the air. Plus, while frying anything, the smell and smoke can create an unpleasant environment if you have guests around. 

Thus, an air purifier can help to reduce the harmful gases, unpleasant fumes, and cooking odors, resulting in a fresh and clean environment.

Enjoy Better Sleep

It’s no secret; sleep is often linked with higher academic performance, reduced depression, and better cognitive abilities. However, sleeping can become nearly impossible if you experience symptoms such as sinus headaches, sneezing, congestion, and stuffy nose due to dust, dander, and mold in your room.

With a top-notch air purifier, you can make your air free of these particles and avoid such issues, leading to better sleep.
