Of the top 10 most polluted cities in the world, six are in India.Amongst the capitals, New Delhi ranks at the top. This has been the story 5 years earlier and this story cotinues even today .Air pollution kills approximately 12.5 lakhs people in India annually, much more than the damage caused by COVID-19. These figures are courtesy the latest “World Air Quality Report” submitted by IQAir.
If these statist is are so alarming, how would you reeact if we say that the indoor air we breathe is much worse than the air outside our homes?
Does It Sound Surprising? Yes, But Unfortunately, It Is True.
The US-EPA (Environmental Protection Agency) has certified that indoor air is nearly five times more polluted than the air outside.If this is true for US households, it will apply all the more to Indian conditions, especially with Indian cities having a dangerous presence in the notorious list of the top 10 polluted cities in the world.
What is the solution for this high pollution levels inside our rooms ?
It would be your follow-up question.
The solution is to have high-quality air purifier for your home and that means investing some money for the air we breathe inside our houses .
This extensive buying guide will explain in detail about air purifiers and why it is advisable to have one in your home.
We shall also discuss the points to note when purchasing an air purifier for domestic use
Before we proceed ahead, let us answer a few basic questions to prepare the groundwork.
Generically, an air purifier is an appliance that purifies the air around you, so that you get pure air to breathe.Air purifiers use a different filters to trap the microscopic dust particles and pollutants that can cause harm. We shall discuss these aspects at a later stage when we come to it. The following examples will drive home the fact.
What is an air purifier?
People who use air conditioners are home would have noticed the amount of dust that collects on the filters. Cleaning these filters improves the cooling capacity of the AC.
Similarly, you would have noticed the amount of dust sticking to the ceiling fans .From where does this dust come?
It does not come from anywhere. The dust particles are already present in the air that we breathe.
Now, you should imagine the importance of our lungs that act as air purifiers for our body. If you have any asthma patient at home, you will easily relate to the trouble he/she might find when breathing in such polluted air.
The key takeaway can be summed up in a single line.
The Cleaner The Air You inhale, The Better Is Your Health.
Let us look at the different types of pollutants in the air that your air purifier can remove
Generally, every house contains the following common types of pollutants.
Dust and dust mites
Cooking odours, chemical cleaners, and toxins from the aerosol sprays that we use, like insect repellents, pain killers, and others
Agarbatti smoke and carbon residues left behind by burning camphor
Volatile organic compounds found in paints, varnishes, carpets, mattresses, and building materials
Bacteria and viruses
Pollen, plant spores, and fungi
Pet dander and hair
Tobacco smoke, especially if you smoke cigarettes.
the above list shows that each of these pollutants can damage your health, whether you have an allergy or not.
When do you need an air purifier at home?
Now that we know that why you need an air purifier at home. Let us now see when you need it the most. Though an air purifier is welcome at any time, the following circumstances require you to go for one immediately.
If you experience frequent bouts of sneezing or coughing because of dust allergies, it is time you invest in an air purifier for allergies. These purifiers eliminate allergens like pollen and pet dander and provide you with much-needed relief.
Houses having asthma patients should immediately decide on purchasing an air purifier. It is one of the perfect ways to provide relief to people living with asthma and ensure that they do not experience respiratory issues.
Pet Dander and hair pollutants
Having pets at home is fun. However, the downsides are that you are exposed to pet dander and hair impurities that you inhale unconsciously. Having a specific air purifier to deal with pet dander should be ideal for such homes.
No Indian home is bereft of smoke. You should be happy and thankful if there are no smokers in your home.
However, every house has to deal with smoke emanating from the kitchen while cooking and also from devotional rooms when you light incense sticks and burn camphor. A high-quality air purifier can eliminate the chemicals from such smoke and make it comfortable
Using mosquito repellents is great for dealing with mosquitoes. Similarly we use aerosol sprays for repelling flies and cockroaches. Even your medicinal sprays for providing relief from muscular aches can pollute the air.
Different Types of Air Purifiers
Purchasing an air purifier can be confusing most of the times. An Indian home usually deals in all the conditions discussed above. That does not mean that you should go for five different air purifiers. You get air purifiers that can cater to all the above requirements.
Though you find an overwhelming range of air purifiers on display online, it finally boils down to the type of filtration methods in use.There are four types of air filtration technology available in India. They cater to almost all the pollutants described in one of our earlier paragraphs.
HEPA (High-Efficiency Particulate Air) Filters
HEPA filtration technology is the best for air filteration. The driving mechanism behind the functioning of HEPA filters consists of a dense paper filter for trapping airborne contaminants.It eliminates various air contaminants like pollen, fungi, mould spores, dust, hair, pet dander, and visible smoke.
When shopping for air purifiers using HEPA filters, you have to be careful. Manufacturers tend to confuse people by using similar terms. You should find out words, “True HEPA Filter” as it can eliminate up to 99.97% of contaminant particles as small as 0.3 microns.
The other names you could encounter are “HEPA Type” or “HEPA like.” These filters are not true HEPA filters and can eliminate particles only as small as 2.5 microns. These air purifiers are 600% less efficient than cleaners using “True HEPA filter.”
The benefit of HEPA filtration is that they eliminate pollutants and do not release them back into the air. Thus, they are safe for almost all kinds of respiratory problems.
The significant negative point is its cost and they need high maintenance costs. Besides, they are not the great filters for eliminating chemical odours. The air purifiers using HEPA filters use a fan to suck air. Hence, they can be noisy at high speeds.
Ionic filtration is a another air filtration technology that operates by emitting charged ions into the air that attaches itself to the airborne contaminants. Thus, these contaminants become heavy and fall onto the floor and other surfaces.
Generally, these ionic air purifiers come equipped with an electrostatic collection plate for attracting and collecting these particles. This purification technology can eliminate particles as small as 0.01 microns in size.
Ionic filtration can remove contaminants like pollen, dust, mould spores, VOCs, fungi, visible smoke, and even some bacteria and viruses.
The primary advantage of ionic filtration is its cost. They are cheaper than the HEP filers.They do not require much maintenance and filter replacements. Since,this technology does not use fans, it does not make any noise.
The disadvantage of ionic filtration is that the pollutants remain in the room on the floor and other surfaces. If the air purifier has an electrostatic plate for collecting these contaminants, one should ensure to clean these plates with soap and water frequently. Besides this technology eminates traces of ozone that can cause respiratory issues in asthma patients
Activated carbon has great filtration properties. You would have seen the use of activated carbon filters in water purifiers and even refrigerators for eliminating foul food smell. Activated carbon contains millions of absorbent pores that can trap fumes, chemical gases, and smells.
These filters do not remove particles that cause health issues but eliminate bad smells. It can deal with chemical and gas fumes, and foul odours from cleaning supplies, smoke, pesticides, paints, cooking, and even pets.
The activated carbon filtration technology is comparatively cheap, easier to replace, and keeps the room smell fresh all the time.
The demerit of this technology is that It cannot handle other contaminants. it is useful for reducing gaseous fumes, odours, and foul smells
This technology entails the emission of UV light (invisible to the naked eye) into the air purifier chamber to contain the contaminants. There is no physical filter through which the polluted air has to pass through for filtration.
As the UV light is not released into the room, it is safe for humans. The primary responsibility of UV Light technology is to remove bacteria and viruses to make the environment free of particles that cause illnesses.
UV lights have a longer life and does not require frequent replacement. They kill the germs and create a sterile environment inside the room.
As this technology can kill germs and bacteria, they can best used only as additional feature along with main other filtration technologies. This technology is not very effective on a stand-alone basis.There are a couple of other minor technologies in use apart from the above prominent technologies for air filteration
They are useful in removing large particles like pet hair to make it easy for the subsequent filtration stages. Some of the pre-filters exhibit electrostatic properties and also use activated carbon to remove odours and smoke. These filters require frequent replacement.
This technology works by passage of the air over an inner ceramic plate heated up to 400 degrees Centigrade to remove bacteria, viruses, mould, and dust mites. This technique is not much effective against VOCs, smoke, and non-organic contaminants.Generally, an effective Air Purifier Comes With A Combination Of More Than One Technologies Discussed Above.
The Classic Version is the traditional appliance that does not provide intelligent information on the type of impurities they remove. However, they work quiet well, as is evident from the dust that collects on the filters over a period.
Some of these now come with digital controls and air quality sensors to aid in the purification process.
The Smart-Enabled Version of air purifiers is compatible with a dedicated mobile app that provides valuable data that help to determine the appliance’s efficiency. They also show the exact nature of pollutants removed from the room and track the air quality level in real-time. Naturally, these air purifiers are comparatively expensive.
So far,We have discussed the different technologies involved in air purification. Let us now understand some commonly used technical words related to air purifiers. You will find these words thrown in almost every specifications list.
ACH – Air Changes Per Hour
ACH is a not much understood by consumers globally. However, it has tremendous significance because it shows the efficiency of your air purifier.you will find ACH ratings mentioned as 4x, 5x, etc. The 5x rating signifies that the air purifier removes and recycles the dirty air in the room with clean air five times in an hour.
Therefore, the higher the number, the better should be the performance.This rating should be seen in toto with the area of the room where you place the appliance. It reflects the maximum square footage the purifier can handle.
CADR – Clean Air Delivery Rate
CADR enables users to know how efficiently the appliance can clean the air in a room of a particular size. It is useful for comparing the effectiveness of the device. Therefore, it is important when you compare two appliances before deciding on the appropriate choice.
The CADR need not be displayed on every air purifier. It helps you to make an honest assessment of the air purifier’s capability to handle a room of a particular size.The CADR rating evaluates three types of air pollution, dust, tobacco smoke, and pollen.
Usually, the CADR is displayed as a set of three numbers to include every kind of pollutant, respectively. Thus, if an air purifier has a CADR of 200/250/225, it entails that the numbers refer to dust, tobacco smoke, and pollen, respectively.
The Higher The CADR Number, The More Efficient Is The Air Purifier At Eliminating The Specific Contaminant.
Impurities are of various sizes. PM2.5 refers to those particulate matter having diameter less than 2.5 micrometres. Roughly translated, it amounts to 3% of the thickness of a human hair.
Particles of this size are not visible to the naked eye. But, they are present in the atmosphere. They can cause be really dangerous for lungs and other organs of our body should we inhale them on a regular basis.
Just as PM2.5 refers to particulate matter having a diameter of 2.5 micrometres or less, PM10 refers to similar matter having diameter 10 micrometres or less. Comparatively, they are larger sized particles.They can also cause great harm when we inhale them.
Let us now discuss how to choose the ideal air purifier size for your room.
Ideal Air Purifier Size for the room
An air purifier is not a one-size-fits-all kind of an appliance. Many people make the mistake of going by the brand name and type without considering the size of their rooms.
The air purifier works best when it can handle the size of the room you place it in. It is not helpful to spend thousands of rupees on an incompatible air purifier. Therefore, the first thing you need to do before purchasing the appliance is to check the square footage rating of the air purifier and compare it with your room size.
This calculation should help you determine the ideal air purifier for your room.
For a single room, multiply the length and width of the room in square feet to get the total square footage.For multiple rooms, calculate the area of each room and add them.
Thus, you get an idea of the square footage rating your air purifier should have. Placement in the room is important. The air purifier should have an ideal placement in your room to deliver maximum efficiency. These following points should prove useful to decide where to place your appliance.
Air purifiers using a HEPA filter and Activated Carbon filters
The design of these filters is such that they use a fan to suck the impure air and push pure air back into the room. Hence, these air purifiers should be placed in areas where there are no obstructions.Placing this air purifier under a table or against a wall will hinder the airflow and affect the overall performance.
The ideal location can be about two to three feet from the walls or furniture to give the air purifier sufficient air space to work at its optimal best.
Air purifiers using Ionic filtration technology
These appliances do not use fans but release ions in a 360-degree angle. Therefore, the ideal placement for these machines is at the centre of the room. Placing it at the corners will end up restricting their efficiency.
Additional Features Present in Air Purifiers
When purchasing an air purifier, you must look for the following features, depending on the type of product you choose.Some of these features come free with the appliance, whereas some might be additional. However, they can prove their worth. Therefore, you should not mind spending a few bucks more if the feature is a useful one.
These attachments are useful because they filter out the larger pollutants like hair and dirt. Thus, they help in extending the internal filter’s lifespan considerably. Normally, these pre-filters are washable.
This is a convenience feature which makes it easy to fix the settings when compared to a push-button or rotary dial controlling option.
Adjustable Fan Speeds
Normally, air purifiers have between two to five adjustable fan speed settings. Some of them come with a turbo speed to cater to specific requirements.
These timers are energy-saving that shut off the appliance after a pre-determined time interval. It helps to prevent the device from running continuously even when you are not at home.
Filter Replacement Indicators
Replacing the filters when they become clogged and unusable is essential to ensure the machine’s efficiency. These replacement indicators alert you when it is time to replace the filters.
This attachment helps you to move the air purifier from one room to the other comfortably.
Casters are wheels that allow easy transportation of the machine from one room to another. Generally, the massive machines have them.
The internal filters get an anti-microbial coating to prevent the spread of bacteria and microorganisms. It enhances the filter’s lifespan while preventing the reintroduction of these germs back into the year.
Air Quality Sensors
Some of the air purifiers have air quality sensors to monitor specific contaminants and adjust the air-purifying settings accordingly.
Plasma Wave Technology
This technology is safer than air ionization because it does not emit negative ions or release ozone. Instead, it used water vapour to achieve a similar effect.
photo catalytic Oxidation
This process works with UV light for oxidizing chemicals and destroying VOCs bacteria, fungi, and moulds.
The top-end air purifiers come with an in-built night lamp to indicate its presence in the dark. Thus, it becomes easy to locate the appliance in your room at night.
You can control the settings of your air purifier from a distance using the remote controlling option.
The smart-enabled air purifiers feature mobile app compatibility to operate the device, monitor data, and diagnose problematic issues, etc.
Additional Points to consider when purchasing an air purifier
Your air purifier is a effective appliance. Hence, it becomes important to take care of the machine. These devices work better when you maintain them properly.
Depending on the type of air purifier you purchase, you incur maintenance costs. Therefore, it is better to have a clear idea of the same before buying the machine.
Air purifiers using HEPA and activated carbon filters require frequent filter replacement, depending on the quality of the input air. As the contaminants get trapped inside these filters and clog them, rendering them unfit for use. It is advisable to check out with the manufacturer before purchasing the air purifier to know the frequency of filter replacement. These filters are also expensive. Hence, you should factor in the replacement cost, as well.
If you purchase the ionic air purifiers or the UV air purifiers, there is no need for replacing filters because they do not have any. Some of the ionic air purifiers come equipped with electrostatic collection filters for collecting the harmful pollutants from the air. These filters are washable and reusable.
The air purifiers that use HEPA filters and activated carbon filters come paired with a fan system to suck the air inside the machine. These fans rotate at varying speeds depending on the settings you choose.
As you increase the speed, these fans can make noise. Some of the air purifiers come with a two-speed setting (high and low), whereas some come with five-speed settings.
The fans require overhauling at regular intervals to prevent them from making noise.Besides, the blades can accumulate dust. They need frequent cleaning to work efficiently. It is somewhat similar to your ceiling fans.
The ionic air purifiers do not have any fans. Therefore, there is no question of any maintenance costs in this regard.
Air purifiers work on electricity. Hence, one should be aware of the energy consumption of your device to determine its efficiency. BEE Does Not Assign Star Ratings To Air Purifiers. Therefore, No One Can Know The Energy Efficiency Of The Appliance Before Purchasing It.
However, one can go for reputed brands to get guaranteed products.
There are a variety of air purifiers available on the market. It can be challenging to select the ideal brand because of the lack of accurate data to compare efficiency.Therefore, it is advisable to go with the manufacturer’s reputation.
Some of the top Air Purifier brands available on the Indian market are Philips, Honeywell, Crompton, Glen, Godrej, LG, HUL Pureit, Panasonic, Prestige, Sharp, and Whirlpool, etc.
Check out the warranties
air purifiers last long in normal situations. However, no one can rule out problems from occurring with these machines.
