According to the United States Environmental Protection Agency, the air inside homes can be up to 5 times as polluted as outdoors. The reason being how buildings are constructed and things we bring indoors that release harmful contaminants. The best air purifiers in India will help you reduce sickness causing elements by purifying the air in your home.

India during festive times, such as Diwali or the wedding season can get incredibly polluted. Delhi and other metropolitan cities can get even more polluted due to the sheer amount of people which leads to vehicle pollution and desperately high concentration of allergens.

Delhi ranked the worst during Diwali of 2019, with the AQI (Air Quality Index) of well over 400, acceptable AQI being 50-100. Air purifiers are a newer technology that actively work to improve air quality by filtering harmful microscopic elements that can cause irritation or sickness.

Advantages and benefits of an air purifier

In practice, what are the advantages and benefits of using an air purifier? It being understood that allergic or asthmatic people will certainly notice the difference, we can all see the benefits for our lungs that this appliance can give. So, let’s see what an air purifier can do for our health.

1. Removes particles that cause asthma attacks

It is in the home that asthmatics are most at risk of having a seizure. Dead skin cells, dirt, dust, carbon monoxide, household cleaners, home fragrances, cooking vapors, paints, cosmetics, perfumes in general, hair sprays, mold spores are all elements found within the walls that can cause an asthma attack. The use of an air purifier is very effective in eradicating these particles, thus lowering the risk of asthma attacks at least within the walls of the house.

2. Removes allergens

Anyone who is allergic to pollen, dust mites or the hair of certain animals is equally at risk of suffering more indoors than outside. However, these allergens are also among the particles that a good HEPA filter can retain almost completely. For this reason, there is no doubt that the habitual use of an air purifier at home is not a little helpful for those afflicted with these allergies.

3. Removes cigarette smoke

Regularly inhaling cigarette smoke can contribute to heart disease, as well as the development of asthma. It is children in particular who are most sensitive to secondhand smoke. For this reason, if a family member smokes at home, for example in the winter months, it would be advisable to use an air purifier to counteract the side effects of secondhand smoke, at least in the children’s room. 4. Removes asbestos particles.

Asbestos or asbestos has sadly become known under the name of Eternit, from the manufacturer of building materials so much used in the past decades. Although the remediation of this material is ongoing, it is still present in many homes. Regularly inhaling asbestos particles can lead to the onset of various cancers, as the news has taught us. An air purifier, however, is also able to retain these particles, for our greater peace of mind.

5. Removes Radon gas

Radon gas, beyond certain exposure levels, can contribute to the development of lung cancer. The occurrence of this gas is quite widespread in domestic environments, although mostly not at levels that are of concern. However, this is also one of the gases that an air purifier can effectively retain.

6. Removes external pollutants

It is established that there is a higher incidence of allergies, asthma and other respiratory problems in urban environments than in rural ones. The cause is obviously atmospheric pollution, i.e., exhaust from cars, boilers and industrial steam. To keep these pollutants out of our homes it is necessary to use an air purifier.

7. Removes carbon monoxide

If we do not have the opportunity to ventilate our home often and we do not keep plants in our rooms, we run the risk of inhaling the carbon monoxide emitted by our own breathing. This can lead to bothersome effects, such as headaches or shortness of breath. To keep the carbon monoxide level under control, we can use an air purifier.

8. Removes flying organic compounds

Many products commonly found in our homes have a very low sublimation temperature, and can therefore release organic compounds into the air with extreme ease. In many cases they are harmful compounds if exposure to them is prolonged: some lymphomas and leukemias seem to be related to precisely this type of compounds. Many paints and varnishes, dry-cleaned garments, air fresheners, aerosols, fuels and car products are all among the products that can release harmful compounds: the air purifier is also useful in controlling the spread of these elements in our homes.

9. Removes some insects

The air purifier, with its suction action, is also effective in eradicating some insects such as mosquitoes, otherwise difficult to eliminate except with the use of sprays and diffusers which, however effective, we end up inhaling too. Fewer midges not only mean fewer annoying bites, but also better protection from certain infections.

The decisive factors for choosing an air purifier

You may already know what type of purifier you want to buy. However, if not, there are other interesting features to consider. Some will come to you completely new. This way, at the end of this reading you can make your choice as safely as possible.

1. Purification system

In the next paragraphs we will see what the most common air purification systems are and how they work, with the exception of ozone generators and thermodynamic sterilization purifiers: these devices do not have filters and have very different operating modes.

An air purifier, in principle, is a very simple appliance: it is essentially a fan that forces the passage of air through a series of large filters. We will now make an excursus of all the filters and sanitizing systems that can be found on an air purifier, but you must know that they will not be found on all purifiers: there are more sophisticated models and others simpler. According to your needs it is therefore necessary to choose a suitable air purifier.

a. Dust filter

The dust filter is a thin and dense plastic grid that performs a first coarse filtering of the largest and most voluminous dust particles. This system also extends the life of the actual filter, allowing it to focus exclusively on the finest particles.

b. Activated carbon filter

Activated carbon filters use the natural properties of carbon. Activation of carbon consists of an oxygen-based treatment that opens the infinite small pores existing between the carbon atoms: the treated coal has an enormously multiplied surface, just think that 450 g of activated carbon have an approximate surface area of 400 m². The principle for which activated carbon has a filtering capacity is called adsorption: when the air passes through this myriad of micropores some types of particles remain attached to it (without penetrating inside, and this is the difference with the absorption).

Activated carbon is particularly effective against flying organic compounds, odors and various polluting gases. Among the flying organic compounds most commonly found in our homes include some components of cigarette smoke and the fumes produced by fresh paint or some detergents. Less common are benzene, toluene, xylene and some chlorine compounds.

Who benefits? Activated carbon filtration is particularly useful for those suffering from asthma or other respiratory problems (apart from allergies)

Should it be replaced? Yes. Activated carbon becomes completely ineffective once saturation is reached, so activated carbon filters must be replaced periodically.

c. High efficiency filter (HEPA)

The HEPA filter is much talk for ten years now, ever since this type of filter has begun to spread in a number of household appliances (vacuum cleaners in particular).

The acronym HEPA stands for High Efficiency Particulate Air and indicates precisely the high efficiency of these filters against particulate matter. HEPA filters have been developed in the nuclear field in order to equip workers and researchers with a filter capable of neutralizing any radioactive particles that may be dispersed in the atmosphere: this helps to make people understand what level of effectiveness we are talking about. Apparently the HEPA filters look like sheets of rigid and thick paper folded on itself like an accordion: in reality the “sheets” are not made of paper, but of very thin glass fibers indistinguishable to the naked eye. The fibers are so dense and endowed with such properties as to effectively block almost all of the particles with a diameter of 0.3 microns and up.

To make you better understand what these filters are effective against, think that when we hear about ” PM10 ” what we are talking about are dust particles from 10 microns in diameter down; in the same way, the “PM2.5” powders are those of maximum 2.5 microns.

Who benefits? For people allergic to pollen and dust mites, since the allergens that trigger these allergies are effectively neutralized by HEPA filters

Should it be replaced? Yes. Even in the case of HEPA filters, periodic replacement is almost always necessary to maintain high effectiveness

d. Ultraviolet sterilizer

In addition to the filters we have seen, some models of air purifiers are equipped with a sterilizing ultraviolet lamp.

When the air passes under this light, the air itself is sterilized: bacteria, viruses, molds and other pathogens are inactivated or destroyed by ultraviolet radiation, thus becoming harmless. The properties of ultraviolet light are widely used in healthcare, for the sterilization of medical equipment and instruments and for the sanitation of environments.

Who benefits? Those who, for whatever reason, are particularly vulnerable to bacterial or viral infections, especially of the respiratory tract.

Should it be replaced? No, the ultraviolet lamp does not have an expiration date

e. Ionizer

The ionizer is a simple and inexpensive device that uses high voltage to attribute a negative ionic charge to the air passing through it. The negative ions produced by the ionizer bind to the particles dispersed in the air, which have a positive charge, and cause them to adhere to the nearest surface.

It is obviously not a method for the real neutralization of dust and pollution: the particles dispersed in the air are simply made to “land” on the floor or walls, where they remain.

However, the opinion about these devices is rather negative: a small percentage, in fact, the ionizer also generates ozone, which is believed to be harmful to human health. A daily dose of ozone exceeding 0.2 mg / m³ is already sufficient to cause long-term damage to the lungs and the olfactory bulb: for this reason, after an initial moment of popularity, ionizers are disappearing from the appliances that have used them. (in addition to purifiers such as humidifiers).

2. Performance

Consumption, coverage, air flow and air purification rate are all elements to be taken into consideration when evaluating the actual performance of the purifier.

Since these data are difficult to deduce empirically at home, we recommend a careful reading of the product data sheet and be wary of those models that do not have them. In the next paragraphs we will illustrate how to correctly read the values ​​shown on the technical sheets and what they refer to.

a. Consumption

The air purifier is a tool that can have very long periods of use as it can remain on for several hours a day or all night: checking the energy consumption of the chosen model before proceeding with the purchase can prove to be a wise choice to avoid finding yourself with nasty surprises when your electricity bill arrives.

In general, however, the consumption of these appliances is modest, especially in those models that use a filter system for air purification. In these cases, in fact, the absorption is around 30/40 W, but the power rises quickly if other technologies are used to support the filters, such as an ionizer or ultraviolet rays. In general, however, the absorption is always less than 100 W.

b. Scope

A determining factor in the choice of purifier is the size of the rooms that it is able to purify, as it is this criterion that determines whether or not the model adapts to your needs.

They range from portable purifiers, to be used for example in the car or on the office desk, able to cover environments of a few square meters, to models capable of purifying even rooms up to 100 square meters and over.

Although it is not a foolproof system, there is generally a relationship between the size of a purifier and its coverage, so a table model will hardly be effective on rooms of many square meters.

c. CADR

The Clean Air Delivery Rate is a measure that indicates how many cubic feet of air are completely purified in one minute (the foot is an Anglo-Saxon unit of measurement and corresponds to 30 cm: one cubic foot corresponds to approximately 0.3 cubic meters): it indicates the efficiency of the purifier in eliminating polluting particles or allergens from the air.

Since tobacco, mites and pollen all have molecules of different sizes, the CADR is calculated separately for each of these three types of particles. This value must be related to the coverage of the model, for which, for the same square meters, the purifier with the highest CADR will be the one capable of making the air cleaner, that is, with the lowest rate of residual particles.

In the same way, knowing the square footage of the environment to be purified, it is possible to obtain the rate of production of clean air that the purifier should have to have a truly effective action: in fact, it is enough to transform the square meters of the room into square feet (1 square meter corresponds to about 10 square feet) and divide the figure by 1.55: for example, to purify a room of 20 square meters the purifier should have CADR around 138.

d. Air flow

Not to be confused with the CADR, the airflow indicates how much air per minute passes through the purifier’s filtration system. This value gives an idea of ​​how long the appliance will take to completely purify the entire room and is clearly strictly linked to the range of the appliance.

e. Noisiness

Since this is a device that remains in operation for several hours, its noise level should not be underestimated, especially if you intend to use it at night.

Depending on the technology used, the air purifier can produce a buzz comprised between 25 and 70 db. The difference is therefore considerable if we consider that 30 dB correspond to a whisper while 70 to the noise produced by an excited conversation: at least on the noisiest models it is therefore advisable to check for the presence of a night mode that allows you to decrease the volume of the buzz at least during the hours of rest.

3. Functions

The more functions, the more you can customize the use of the purifier according to your needs. Let’s see which are the most common ones:

  • Operating levels: The different operating levels an air purifier can be equipped with allow you to adjust the performance of the appliance according to your needs in order to avoid unnecessary waste of energy, for example in the event that the environment that it is desired to purify were smaller than the maximum flow rate of the purifier.
  • Night mode: Where present, the night mode slightly reduces the performance of the purifier while reducing its noise level so as not to disturb the night’s rest. As we have seen, this function is particularly important on models with a noise level higher than 40 db.
  • Timer and auto shut-off: The presence of a timer allows you to preset not only how long the air purifier should remain in operation, but sometimes also the time for automatic switching on and off. In this way it is possible to return to the house and already find clean air.
  • Air quality sensor: In some models it is possible to find an air quality sensor that indicates the level of pollen, mites or polluting particles present through bright LEDs of different colors (for example: red = high concentration, green = clean Air). The sensor can be useful not only to adjust the level of operation, but also to have a view of the progressive improvement of air quality.
  • Dehumidifier: Some appliances are also equipped with a dehumidification function, to be activated if, in addition to purifying the room, you also want to reduce the humidity of the air, the excess of which can lead to the formation of mold on the walls.

4. Maintenance and structure

A few last considerations before proceeding with the purchase must be made on the maintenance required and on the structure of the appliance. Even if these are not the most important factors on which to base your choice, the structural aspects and the frequency with which maintenance of the appliance is required can in fact have a considerable impact on its practicality of use.

a. Spare parts

Although in general it can be said that air purifiers do not require major maintenance, it is also true that periodic replacement of the filters is necessary to function correctly. Generally, these must be changed every three months of use (so if the air purifier is used only sporadically, the time interval between one replacement and the next will also expands accordingly) and it is therefore important to check that these are easily available and that the price is within everyone’s reach.

Some purifiers are also equipped with some sort of reminder function: this can consist of a simple stop of the appliance or a warning light that warns when the filter is no longer able to purify the air.

b. Dimensions

A second evaluation must be made with regard to the dimensions and structure of the appliance. Unless you are oriented to the purchase of a portable purifier to be used in the car or in other confined spaces, it will be necessary to take into account that these devices are certainly not large, but still such as to require a specific location.

You can find on the market both turret and parallelepiped- shaped purifiers, the latter to be placed either on a shelf or directly on the floor. It is difficult to say which of the two solutions is the most appropriate, it is certain that the design can do its part and help make the air purifier more in line with home furnishings.

The weight of the object also plays a part in the dimensions, especially if you have children in the house who could bump or drop the appliance and get hurt.

Always linked to the weight is the possibility of moving the purifier from one room to another. In the event that the environment to be purified is particularly large and divided into rooms, it could in fact be convenient to opt for a purifier equipped with a handle and / or wheels for transport, to be able to move it from time to time where necessary rather than buying one per room.

c. Accessory components

On some models it is sometimes possible to find accessory components which, although not essential, can be a welcome extra. For example, we are talking about the presence of a remote control with which to adjust the settings of the appliance even at a distance or that of a tray in which to pour a few drops of essential oil to perfume the air as well as purify it.

5. Materials

The materials are certainly important in the choice of the purifier, but we are not referring so much to the materials in which the internal structure is made, as to those with which the filters are produced.

In fact, we reiterate that each filter has its own specific function, and must be made of an appropriate material. To remove unpleasant odors, an activated carbon filter is required, while the HEPA filter must be equipped with a glass fiber coating, the thickness of which affects its effectiveness. It is also a good idea to check that the filter is coated with an antibacterial protection, so that the bacteria, germs and molds retained do not damage the filter itself.

6. Brand

Many of the large companies that deal with the production of household appliances have one or more models of air purifiers in their catalog. We are talking, for example, of Philips, Electrolux or Mi, well-known and reliable brands. However, there are just as many brands whose production is focused on air conditioning, heating and air treatment appliances, such as Daikin and Dyson, whose products, although less known, have nothing to fear in comparison with those of the more famous but less specialized.

For whichever brand you opt for, it is essential to check that the replacement components, mainly the filters, are essential when choosing, are easily available and possibly produced by the same company, so as not to have any doubts about their compatibility with the appliance.

7. Price

Buying an air purifier can be an important expense, often exceeding Rs. 10,000. It is always better to be wary of products priced below Rs. 3,000, because at best they have a very limited range and at worst they turn out to be totally ineffective. In fact, the price is not only influenced by the purification systems used, but also by the air flow and the coverage: the larger the room to be humidified, the more expensive will be.

8. Other features

Features such as warranty, maintenance cost, noise level and energy consumption are also just as important and varies with make and model.

  • Filter Replacement Indicators: Indicators that alert you when it is time to replace the filters can be really helpful for places with higher levels of pollutants. Essentially keeping the purifier running at full potential at all times.
  • Adjustable Fan Speeds: Air purifiers can have adjustable fan speed settings, ranging from low to high. Some purifiers even include a turbo button to speed up the purification process.
  • Digital Controls: Digital controls provide precise settings for air quality control as compared to a traditional push button design.
  • Pre-filter: A pre-filter captures large particles, like dirt and hair and essentially extends the life of the internal filters. They are washable and can be reused for as long as possible.
  • Programmable Timer: Timers help with energy saving. This feature shuts off the device after a set amount of time so that no more energy is used than required.
  • Rolling Wheels or Casters: Casters help with portability and can be rolled to different parts of a room or different rooms entirely with lesser effort.
  • Air Quality Sensors: An automated service that monitors the air for specific pollutants and automatically adjusts the purifier to properly deal with these pollutants.
  • PlasmaWave Technology: An alternative for using negative ionic purifiers, they do not emit ozone as a by product and uses water vapor to achieve similar effects as an ionic purifier.
  • Antimicrobial Treatment: A coating that prevents the build-up of bacteria and microorganisms on internal filters, it helps with increasing the lifespan of filters and prevents the re-release of said bacteria back into the air.
  • Photocatalytic Oxidation (PCO): A more advanced filtering process, coupled with the UV purification method to destroy harmful organic compounds, bacteria and germs from the air.
  • Mobile App: A mobile app lets you fully control the features of the air purifier. They help with monitoring data and gives real-time information about the cleanliness of the air and the pollutants present in the room.
  • Nightlight: A nightlight to easily find the device in a dark room.
  • Remote Control: A remote control to use the device from a distance.

Frequently Asked Questions (FAQs) about Air Purifiers

Now that you have discovered some of the best air purifiers on the market, you are already familiar with several features of these devices. In this section we will examine some questions that are important to consider before making a choice. Buying this device will involve a pretty big expense, so don’t rush.

1. Do air purifiers really work?
