Essential Factors to Consider Before Purchasing an Air Purifier

Apart from the product features and specifications, we have mentioned some essential points you should check prior to buying the best purifier in India.

  • Air Purifier Rating

Usually, air purifiers are rated on the basis of two merits, one is CADR, and the other one is the POLAR test. Firstly, the POLAR test rules out the condition of a room and then examines the functionality of an air-cleaning appliance using several sensors. On the other hand, CADR is a conventional way to figure out the amount of clear air generated by an air purifier every minute or second.

However, experts recommend that the former one is more efficacious than the latter as a determining factor

  • Coverage Area

Air cleaners come with different capacities, and the fan speed determines how much area the appliance will be able to cover. You can check the area coverage capacities of each air purifier model mentioned above in the first section and then choose one according to your need.

  • Pollutants

Another significant factor is the pollutant that you want to eliminate with the help of an air purifier. For instance, if you are facing issues with the growth of bacteria, mould, viruses, etc., you can consider any of the allergen-specific air purifier variants available. 

Furthermore, if you have pets at home, you will experience the issues with their shedding of hair and dander. Plus, pet dander also releases the odour. Hence, you will require a product that can easily intercept both the issues of pet dander and odour emitted from the same.

Types of Air Purifiers Available in the Market

  • HEPA

HEPA or High-Efficiency Particulate Air is one of the extensively used filter technology in air cleansers. It can capture all kinds of pollutants ofthe size of more than 0.3 microns and offers an efficiency rate of around 99.97%. The human eye can see substances and compounds of size 10 microns. So, it means that HEPA filters can trap microorganisms like bacteria, viruses, etc. and other tiny particles.

However, HEPA filters can only eliminate pollutants from the surrounding atmosphere.

  • UV

Though UV light cleansers cannot entirely remove airborne contaminants, they can destroy and kill injurious viruses and other germs.Besides, UV light is divided into three sub-bands, out of which UV-C is used in air cleaning appliances.

The air cleansing products have a UV lamp fitted in them, and the rays emitted cause genetic or cellular damage in the microorganisms, thus, preventing the germs from multiplying or growing.

 
  • Ionic

Ionic air cleaners attract the airborne contaminants. Due to this interaction, the particles become heavy and stick to solid bodies present in a room like floors, walls, windows, etc. Instead of capturing or absorbing the pollutants, these kinds of air-purifying appliances mask them. 

Hence, it is considered less productive in comparison to other cleaners.

  • Ozone

Ozone readily reacts to eliminate the foul smell or strong odours of chemical agents present in a household. This unstable oxygen molecule is a useful compound to kill mildew and mould as well.

  • Activated Carbon

Unlike HEPA filters, air cleansers enabled with activated carbon technology can absorb both pollutants and odours of tobacco smoke, chemical emissions, etc. Activated carbon is nothing but a highly porous form of carbon that provides a large surface area to absorb huge amounts of contaminants.

People suffering from MCS (Multiple Chemical Sensitivity) may opt to buy activated carbon air purifiers as they can capture the carcinogenic formaldehyde

These products have a fan installed that helps to draw in air.

 

Benefits of Purchasing an Air Purifier

Air purifiers do not only clean the air around but also offers several other benefits too. In the following section, we have pointed some of the exceptional air purifier benefits:

  • Good for Asthma Patients

The ‘Centers for Disease Control and Pollution’ states that 1 out of 12 people suffer from asthma. Due to the presence of dust mites, pet dander and pollen grains, people experience more difficulty in breathing, as the mentioned pollutants trouble their respiratory tract.

  • Eradicates Injurious Pollutants from the Environment

In large cities, individuals are more prone to harmful vehicle emissions like nitrogen dioxide and carbon monoxide. These gases can lead to conditions like dementia and Alzheimer’s disease. Besides, house cleaning disinfectants contain chemicals like chlorine, phthalates and ammonia. Although these are harmless in lesser quantities, if exposed for a prolonged period, it can give rise to several health disorders like cancer, tumour, etc. 

Hence, purifiers which feature activated carbon technology can assist in eradicating these pollutants and ensuring a healthy environment.

  • Provides Relief from Mosquitoes

As new technologies are invented, some air purifiers also work as an excellent mosquito repellent. By placing them in your bedroom, you can remain assured to enjoy the best sleep throughout the year.

  • Protects Against Skin Problems

As air purifiers capture the toxins that cause skin disorders, it helps prevent acne, itchiness, etc.

  • Removes Unpleasant Odour

Volatile organic compounds (VOCs) like benzene, formaldehyde and gasoline generate unpleasant odour as they undergo reaction in room temperature. These compounds present in air fresheners, aerosol sprays, paints, etc. can develop health problems like nausea, loss of breath, etc.

Here also, carbon activated and HEPA air purifiers play a significant role in trapping both the odours and particles from the atmosphere. Apart from chemicals, air purifiers also absorb smell from cooking and spices.

  • Protect Individuals from Detrimental Effects of Radon

Another benefit of HEPA and carbon activated air cleanser is that it absorbs radon. If you are wondering what radon is, look below:

Uranium is a naturally occurring radioactive substance found in construction materials, which upon disintegration releases radon. This colourless and odourless gas is carcinogenic and leaks through cracks in walls, floors, etc. It has the capability to develop lung cancer in human beings.

  • Prevents One from Colds, Cases of Flu and Several Other Infections

UV light air cleaners can protect individuals from catching a cold, flu, etc. These appliances not only trap the disease-causing germs but also kill them.

Frequently Asked Questions

Ans. Experts do not encourage the use of ozone purifiers, and it is even restricted in some places. These purifiers produce significant amounts of ozone, which is indeed harmful to human health. For instance, it can cause long-term effects on lungs and olfactory cells. Some studies suggest that if minimal amounts of ozone, like 0.08 parts per million, are inhaled for a 7 hour period, it gives rise to bronchial hyper-reactivity.

On the other hand, ozone also undergoes reaction with house cleaning products like terpenes to form formaldehyde, which is a carcinogen. So, these are some of the crucial reasons why ozone purifiers must not be used.

Ans. It is difficult to determine the best air purifier in India. It entirely depends on users and their preferences. Also, some people may prefer a particular company for air purifiers. However, before going to purchase, you must keep in mind certain aspects like space, the pollutant you want to get rid of, etc.

Ans. Appliances like humidifiers and purifiers are used to serve different purposes. The former is utilised to maintain and control a room’s humidity, while the latter captures dust, allergens, etc., from the air.

Therefore, both of these products are incomparable, and one cannot definitively determine one to be better.

Ans. There are certain things one should keep in mind before placing an air purifier. Firstly, you must select a location where the concentration of pollutants is high and should not be on the ground. You must place it at least above 4 feet from the floor. Secondly, avoid placing it in the corners and areas with high humidity like toilets and kitchen.

Ans. A high MERV rating denotes a purifier’s increased capability to clean the air, and individuals always prefer to choose the same. But, purifiers with a higher MERV rating come with a thick filter, which consumes a lot of energy.

MERV rating ranging from 5 to 8 is considered appropriate for household purposes, capable of cleaning the air from dust, pollens, etc. Furthermore, if you or any of your household members suffer from respiratory complications like asthma, allergies, etc., it’s recommended to purchase purifiers with a MERV rating of 10 to 12. These appliances can remove microscopic particles of size 1 micron like mould spores, car exhaust, etc.

Ans. 4 kinds of air filters are available in the market: fibreglass, polyester, HEPA, and washable. The first 3 types have extensive usage in both homes and workplaces, but the washable ones are primarily used for industrial purposes. As the name suggests, they can be cleaned and reused.

Ans. The only dissimilarity between HEPA and true HEPA filters is their capability of air filtration. While HEPA filters offer an efficiency rate of 99% to capture particles of size 20 microns, the true HEPA filters come with an efficiency rate of 99.7%. These products can capture particles of size as small as 0.3 microns.

Generally, a purifier takes around 30 minutes to 2 hours to clean a room, depending on certain factors like purifying coverage, fan speed, and room dimension.
