Are Air Purifiers Worth It? 5 Benefits of Having an Air Purifier at Home

The well-being of your family members largely depends on indoor air quality. Even when you spend long hours in a centrally air-conditioned room, you have no respite from polluted air. Indoor air can be five times as polluted as external air since there’s no fresh air circulation in an enclosed environment. So, you’re never safe whether you live in an air-conditioned home or a centrally cooled workplace!

To mitigate the risk of heart diseases and other common ailments stemming from inhaling contaminated air, HVAC experts like Hurliman Heating recommend installing air purifiers indoors. You can click here to learn more about professional service providers.

Now, you might wonder about the sheer necessity of purchasing an air purifier when you already have an AC installed to keep the rooms cool. 

How do air purifiers work?

The functional mechanism of an air purifier involves a filtration system to eliminate airborne particles indoors. This way, air purifiers recirculate clean air in your rooms. Even when you have your AC running, you can never weed out pollens, spores, pet dander, or moulds completely. Based on the nature of the air filter, the purifiers stain out these pollutants.

The fan in air purifiers draws the surrounding air in. Next, the air passes through the filter present in the air purifier. This filter may be available in different materials like fibreglass or paper. Based on the density of the filters, they trap contaminants above a particular size.

HEPA filters are of the best standard, capable of filtering particles larger than 0.3 microns. The filtered air keeps circulating indoors, and this is how you get breathable air of better quality.

Some of the other types of filters in air purifiers include:

  • Activated carbon filters
  • Electrostatic Precipitators
  • Ozone generators
  • UV light air purifiers

Benefits of installing an air purifier at your home

Now that you know how air purifiers work, let’s check out whether it’s worth installing these appliances indoors.

1.    Removes allergens

While your AC is good at keeping the indoors cool and maintaining the right humidity level, you can still have allergens in your rooms. Allergens refer to elements that can cause allergic symptoms in humans. Some allergens present  in the conditioned air include:

  • Dust mites
  • Pet dander
  • Pollen
  • Mould

Allergic reactions can lead to a runny nose and irritation in the eyes, throat, and nose. Air purifiers filter this particulate matter effectively. HEPA filters, in particular, are efficacious in filtering yeast, mushroom, and moulds.

2.    Cleans indoor toxins

Indoor toxins often originate without your knowledge. Even common household items like personal care items and cleaning compounds can release these toxins. 3D printers and a wide range of electronic accessories in your enclosed commercial environment are also sources of these toxins. Besides, you have smoke from cigarettes, which can affect non-smokers and pregnant women.

Some air purifiers come with photocatalytic oxidation technology – a powerful purification technique that can significantly reduce airborne toxins. These purifiers deploy the energy from UV light to neutralize airborne particles.

3.    Removes unpleasant odours

Industrial and commercial working environments have different chemicals like formaldehyde, benzene, and gasoline, which disintegrate at ordinary temperatures, releasing unpleasant odours. Commonly, you would find these chemicals in aerosol sprays, paints, air fresheners, and upholstered furniture. These chemicals are commonly known as VOCs (volatile organic compounds). The smell from these compounds can disrupt your cognitive functions, causing nausea or breathlessness.

Air purifiers with activated carbon or HEPA filters can trap these particles. This reduces indoor air pollution, giving your staff a better place to work at. With low levels of VOC in the ambient air, you can boost your performance and productivity.

4.    Low chances of airborne diseases

Having air purifiers in your interiors can partially reduce the chances of airborne diseases like flu and the common cold. When one of your family members gets the flu, the disease affects the others after a few days. This is because these pathogens transmit from one host to another. With the same air circulating indoors, bacteria and viruses can easily affect everyone.

Installing an air purifier is an effective way to safeguard your home or office against contamination. Advanced air purifiers with HEPA filters are capable of capturing these microorganisms. Particularly, if you have someone with a weak immunity system at home, these air purifiers can be a game-changer.

5.    Eliminates asbestos

In case you reside in an old house, you know how dangerous asbestos can be. As the structure ages, the asbestos particles make their way into the ambient air. Inhaling these particles can lead to the scarring of tissues in the lungs, causing adverse ailments. Besides, it can amount to swelling in the face and neck, difficulty swallowing, and loss of appetite. Apart from asbestosis, severe conditions can also lead to lung cancer.

Air purifiers with the right kind of filters can capture harmful asbestos particles. Established HVAC professionals like Hurliman Heating can recommend the best types of filters.

Can you use air purifiers with ACs?

Yes, you can use an air purifier along with an air conditioning system. The primary function of air conditioners is not to purify the air but to cool down your interiors. Therefore the air can be cool and still be contaminated for your health. Thus, the need to purify the indoor air arises when you work or live in an enclosed or air-controlled environment for a long time.

Although they complement each other, air conditioners and air purifiers perform different tasks. Installing air purifiers along with an AC defines a foolproof approach to maintaining a healthy indoor environment.


As you might have noticed, air purifiers have become a necessity with growing pollution levels across the world. Get in touch with an HVAC professional who will help you pick the right purifier for your environment. There are several options available with different filters. Your choice would depend on the levels of existing pollution in your area. Places with ongoing construction need a powerful filter. In contrast, a standard residence can work even with a basic air purifier. Contact a professional today.
