Things to Consider While Purchasing an Air Purifier

To choose an air purifier, you need to consider several factors like room size, power consumption, noise levels and finally the cost. We have tested on many and checked the performance by switching to low-high speed variations.

Given below are the factors responsible for the better performance of air purifier. Check them in detail.

1. Types of filters used in air purifiers

Different air purifiers types target different pollutants, so it is important to identify the pollutants that you want to eliminate from the room and enjoy the fresh air. For your convenience, we have provided different types of filters used in purifiers. Let’s have a glance at the Top 5 air filters for home that are very popular now. (2)

(a) HEPA filter(3)

HEPA is the acronym of High-efficiency particulate air. This HEPA filter has major application in homes, offices, automobiles, air crafts, and hospitals to remove impurities present in the air.

It satisfies the standards set by the DOE- Department of Energy. To qualify, it should filter out 99.7% of PM 2.5 particles.

The best HEPA air filter in India is typically made with fiberglass material and the pollutants, particles can easily pass through it and the working can be explained using 3 mechanisms namely- interception, impaction, and diffusion.

Large contaminants get trapped when they pass through the fiber layer via interception mechanism. Medium-sized particles move through the filter via impaction and diffusion mechanism for small pollutants. All of them bump into the fiber layer and set-up on it.


  • Improves health.
  • Best cheap air filter.
  • Removes 99% of PM 2.5.
  • Produces fresh and clean air at indoors.
  • Can be used as high-efficiency furnace filters.


  • Cannot handle smoke and odors.
  • Incapable of trapping small particles.
  • Microbes stick to HEPA filter can reproduce, resulting in more number.

(b) Activated carbon filter

Activated carbon or charcoal is processed to have a small volume of pores that helps to increase the surface area available for any sort of chemical reactions. 1 gram of activated carbon contains 3000Sq.m of surface area.

The properties of activated carbon like high chemical bonding and absorbent ability will make the device more efficient for capturing harmful pollutants like gases, smoke, and odors. Once the carbon filter traps all the particles, they cannot release back into the air thereby eliminating particles completely.

For those, who are willing to have high-end air purifiers in Delhi that completely deter the odor, smoke, and VOC (volatile organic compounds) then it’s preferred to use an activated carbon filter.


  • Most absorbent filter.
  • Robust design.
  • Easy to maintain.
  • Best budget air purifier filter.
  • Filters fumes, smoke, gases and odors.
  • Will not release pollutants back into the atmosphere.


  • Shorter lifespan.
  • Not effective against bacteria and viruses.

(c) UV technology

Implementing UV technology in air purifiers is an excellent method to kill harmful bacteria, and viruses.

When you install it in purifiers, the microorganisms passed through the UV rays are no longer existed.  Its primary function is to kill only the bacteria, viruses, yeasts, and molds. But cannot handle the dust, smoke or allergens in the air. To attain greater performance, it is associated with other filters where it cannot do specific operations.

When you purchase the UV air purifier, make sure the system does not produce ozone (high-concentration).


  • Easy to clean and install.
  • Best air filter for home.
  • Reduces unpleasant odors in a kitchen.
  • Focuses on eliminating microscopic elements.


  • Expensive filter.
  • Do not kill the harmful particles present in the air.

(d) Negative Ion

Negative ion is a system that uses high voltage to ionize or charge the air molecules. It is a high-end air purification process that is fabricated around ion generators.

The working operation of the device is such that it drives the stream of negative ions that attract dust particles and allergens in the air. As the majority of atoms are positively charged, they are attracted to the surfaces, walls and floors.

Some of the particles are being trapped by ionizers containing a metal plate and they need to be washed very frequently to perform the tasks effectively.

The major advantage of using ionizer filter is that it removes ultra-fine particles up to 1 micron without using fans or motors.


  • Helps to promote deep sleep.
  • Very inexpensive filter.
  • No use of fans or motors.
  • Removes the elements up to 0.01 microns.


  • Doesn’t remove odors.
  • Harmful to asthma patients.
  • Releases ozone into the air.

(e) Ozone

Ozone filters are designed to protect from all kinds of toxins in the air unless the concentrations are higher than the people health standards. Its functionality is similar to the ionizer, but it alters the oxygen molecules and turns to ozone. It is very good at deodorizing and disinfecting the air.

As there are many popular brand ozone purifiers, all of them vary in the production of ozone.  Ozone cannot purify the air and is considered as the toxic gas due to the unstable molecules which are responsible for causing breath-related problems.

If you are an asthma patient or prone to breathing issues, then strictly avoid using ozone purifiers at home. For such people, it is recommended to use HEPA filters or Ozone-free air purifiers in India.


  • Eliminates toxins at high concentration levels.


  • Do not remove particulates.
  • Ozone is unstable and potentially a toxic gas.

To increase the lifespan of any air purifier, you need to change the filter very frequently say- once in every 2-3 months. It, in turn, protects you from inhaling poisonous gases and keeps you healthy all the time.

2. CADR- Higher the CADR better the Air Purifier

CADR abbreviated as Clean Air Delivery Rate. It is actually a performance indicator to determine the efficiency of an air purifier. Most people often get confused with the terminologies like airflow rate, filters, and CADR air purifiers. Here is what exactly the CADR rate is all about.

What is CADR?

CADR rate defines the maximum amount of clean air offered by an air purifier. In other words, it can be expressed as how well the purifier can reduce the allergens, pollutants, and chemicals in a room. Higher the contaminants, faster it purifies the air.

The tests of CADR are being carried out by AHAM-Association of Home Appliances Manufacturers to analyze the performance of a purifier with respect to dust, pollen, and tobacco. Initially, the purifier is kept in a small/medium sized room and CADR rate, the percentage of impurities are determined in just a time gap of 10-20 minutes.

 Given below table completely explains the CADR ratings of different impurities present in a room.

Impurities CADR Rating (Microns)
Pollen 5 – 11
Dust 0.5 – 3
Tobacco smoke 0.10 – 1

To be more specific, higher CADR air purifier filters very quickly than the lower ones. In case, if both the purifiers have the same CADR-rating then purifying performance will be the same.

ACR- Air Change Rate

Air change rate is a key factor for controlling indoor air-pollutants. It is defined as the volume of fresh air needed in a room by measuring the number of persons and size irrespective of indoor airborne chemicals.

Higher the ACR, the higher air flow and energy consumption and vice-versa. It is recommended to have purifier with 250-700 ACR which is too good in a bedroom to breathe fresh air.

To calculate the room air changes, measure the airflow in a room and multiply with 60 minutes per hour. And then divide with the volume of the room in cubic feet.

ACH =   60*Quantity/Volume

For example, if the volume of the room is 1000 cubic-meter and 4 is the no. of times the air changes per hour. Then the resulting air flow rate is 4000 (4*1000=4000) and the air shift per minutes is  60/4 = 15-mins.

3. Size of the Room

You must be familiar with the room size if you wish to have air purifier. The best way to go with is by measuring the room size in square feet.

There are many air purifiers available in the market ranging from compact size to big. Of the available, which air purifier is the best? Obviously, you must opt for the one that is capable of cleansing the air in large space than the actual size of a room.

Here, the given below table explains the CADR rating with respect to the size of a room that helps to choose a specific purifier.

Rooms (in square feet) CADR
Bedrooms  (300 Sq.ft) 140
Living rooms (400 Sq.ft) 250
For entire house 400

 4. Power Consumption

Most of the air purifiers consume a lot of power as they utilize fans and motors to blow air strongly through the filters. On a scale, they consume 30-250 watts of power depending on the size and models.

So choose one that is able to purify the air and also consumes very less power. Of the 10 listed, we have given the power consumed by each product in detail. Check it out.

5. Noise Levels

The purifiers come with 3 or 4 fan settings. The fan usually runs with the help of motors to pull the air inside and then start cleaning operation. When you run the fan for a long time (say 8-12hours continuously) in high mode then there are more chances of producing a lot of noise than low or medium settings.

If you are going to buy an air purifier for indoors, then you have to check for the noise produced in each and every air purifier brand as it makes you feel bit irritative and also spoils your mood.

6. Pollution-free

Some purifiers may pollute the air by spreading ozone, which is highly dangerous for asthma patients, children and elders. Therefore, it is better to avoid such ozone releasing air purifiers.

The best alternative is to look for purifiers that are CARB (California Air Resource Board) certified which is a most stringent testing agency for the consumer products.(4)

7. Manufacturers Reputation and Warranty

Manufacturers reputation is how you get to know about the item. Many of the popular or best air purifier brands in India are appreciated in the industry for various reasons like quality and performance it mainly focuses on.

As air purifier is a long-term investment and you don’t want to replace it with a new one when it becomes faulty. Just like other electronic devices or gadgets, the air purifier is offered with a warranty card. It is highly recommended to look for the manufacturer’s warranty as it helps to avoid the potential damages or the maintenance costs.

Also, read the terms and conditions offered by the maker as it entirely covers motors, fan, filters and other parts.

8. Cost of an Air Purifier

The cost is the main factor to be considered before buying an air purifier. It gives a clear idea of what and how effectively you are going to use the purifier.

If you are on a very tight budget, and still wish to have the best home air purifier in India, then go with the basic models like Mi Air purifier 2S bundle with Echo Dot that comes at very low prices. Though it may not offer all the smart features, its main function is to remove the harmful chemicals in the air that causes great damage to the human health.

The above-mentioned basic model may not solve all the purifying issues. So there is an urge of air purifiers that comes with the advanced features like smart navigation, and timer settings. Here in this article, we have mentioned some of the top-class purifiers like Mi,Coway,Honeywell,and Philips models that best matches the consumer requirements.

9. Some Amazing features of Air Purifier

Most of the purifiers use Fan to capture air for performing a filtration process. Purifiers with fans run more effectively with little noise whereas the ones without fans work poorly.

Programmable Timer is a counter that generates signals when it finishes the count. It allows the users to set purifiers work for hours and then turn off automatically.

Remote controller option will let you adjust the purifying settings in a room.

Dirt sensor helps to detect the dust particles present in the air automatically. In some models, it automatically adjusts the fan speed to level dirt in the air.

Washable pre-filters collect a large number of dust particles and can be washable after usage. It will help you to cut down the overall or maintenance costs. However, the basic models don’t feature this option.

The Carrying handle makes easy for the users to move the purifier from one location to another. Not all the manufacturer offers this extra feature which also makes the device look unique.

Different types of pollutants

According to the reports given by the WHO-World Health Organisation(5), says that pollutants released at indoors are more likely to attack the people’s health by 10 times than outdoors.

Indoor air pollution is due to the 4 major factors like combustion, building materials, bioaerosols and the ground under the building. Besides these factors, there are major contaminants that not only spoils the indoor environments but also the person’s health is given below.

An Airborne particle is a particulate matter that contains pet dander, spores, dust allergens, pollen, fungi, bacteria, and viruses. All of these are responsible for causing severe health problems like allergies, asthma and other breathing problems.

Tobacco smoke is the practice of smoking tobacco and inhaling the smoke. It is the traditional air pollutant and is the major cause of cancer.

Household odors include harmful gases, toxins and pollutants like aerosols, pesticides, and aerosols. It is very common in every house and is seen in more quantities. Activated carbon filter is the best choice for absorbing the gases and odors than being trapped by HEPA filter.

VOC- Volatile Organic Compounds are the chemicals that have a high vapour pressure at room temperature. These sort of compounds are mostly seen in domestic products like paints, disinfectants, glues, adhesives and cleaning supplies.

They spread micro-organisms like bacteria, viruses, mold, and pathogens that are responsible for causing eye irritation, headaches, nausea and may even damage the nervous system.

A table given below illustrates the type of impurity and average particle size which is expressed in microns.  A micron is stated as (1/25000)   of an inch. As the harmful toxins are expressed in microns, here is a list.

Impurity Type Microns
Oxygen 0.0005 microns
E missions from car 1-150
Bacteria 0.3-60
Molds 2-20
Spores 3-40
Fungi 0.5-5
Pet allergens 0.3-100
Dust 10-40

Tips to Handle purifiers

Choosing the right air purifier doesn’t matter. What matters the most is the purifier that you purchased should be used properly. To make the device worth it, here are some of the useful tips so that you can set up, install and use proficiently.

  • Initially, choose the best air cleaner for home use to fix in the right location.
  • Before you mount it on walls or wooden blocks, make sure the clean airflow is directed in the right direction.
  • For better performance of the purifier, keep windows and doors locked.
  • It is also important to change the filters regularly.
  • Now-a-days, washable filters are available in the market, so you can directly replace regular ones with them.
  • Avoid placing the purifiers in extreme hot or cold room climatic conditions as the extreme conditions can block the airflow.
  • If you are a pet lover and have them in your home, then stop pets entering the room to lessen the allergens.

If you follow the above-mentioned tips, then you have fewer chances of affecting to diseases or other health risks.

Types of Air Purifiers

With an increase in the number of houses, purifiers are becoming more self-sufficient and make indoor reach fresh and clean air by deterring dust particles, molds and allergens. Given below are some of the possible air purifiers that are helpful in solving different issues.

  • Portable air purifiers

Portable air purifiers are often called as room air purifiers. If you don’t have heating or cooling system in a house, then this is for you. It is the best bedroom air purifier as they come at very low-prices and also performs the tasks accurately (without any delay).

They are light weighted and comes with a stylish design. As it is equipped with HEPA filter, there are more chances of removing 99.7% of particles that are less than 0.3 microns.

  • Whole-house air purifiers

Another option to go with is the whole-house air purifiers. It is attached to heating or cooling systems that can be connected via electrical system. They can even clean the big-sized rooms and is a great option for those with allergy-related health problems.

  • Commercial air purifiers

They are capable of handling a large number of contaminants when compared to the standard air purifiers. When you prefer to use commercially, you must be aware of different sources of pollution in a room or big halls.

These systems are equipped with PCO-photocatalytic oxidation plus HEPA filter, to offer protection against the harmful bacteria, viruses, chemicals, and VOCs.

  • Pet air purifiers

As per AAFA-Asthma Allergens Foundation of America, people who suffer from 30% of allergens are more likely to affect with the pet’s dander, skin, and fluids.

Symptoms of pet allergies include itching, nausea, asthma, and rashes. They last for several months and is unpredictable.

The only solution to this problem is by using pet air purifiers that help to get rid of dried saliva, hair, and dander of pets.

To deter pet allergies and odours, it has come with HEPA filters, Ionizers, and UV technology. They are very cheap and disposable too. The allergy physicians also suggest you to use only 4 hours a day to completely eliminate the pets thing.

  • Smoke air purifiers

Tobacco smoke is hazardous to health as it contains chemicals and smoke particles. Smoke particle size could be of 0.01-1 micron that helps for penetrating into small areas and also cause discoloration to the room surfaces.

When you are exposed to tobacco smoke, it results in long-term health problems like lung diseases, and cancer as it contains around 4000 chemicals like formaldehyde, carcinogenic, benzene, vinyl chloride, ammonia, and arsenic.

Most of the people think that purifiers are ineffective in cleaning tobacco smoke. But it’s totally a misconception.

Now our aim is to neutralize the smoke odors in a room. To make it happen, use purifiers with carbon filters. They are often named as miracle filters because they have the ability to remove chemicals, VOCs, and odours.

This is an exceptional choice for those who smoke daily in their rooms or at bars & restaurants as it completely eliminates the hazardous smoke and allows you to breathe clean and fresh air.

  • Electrostatic precipitator

An electrostatic precipitator is a device used to filter out the particles like dust and smoke. They are actually designed to recover the valuable industrial materials that are used for pollution control at industries and power generating stations.

Its functionality is similar to the Ion and ozone generators. Yet, the particle is collected on a metal plate and can be cleaned for further usage.

The major con of this device is that it produces ozone which results in chronic respiratory problems.

Best Air Purifier Brands Comparision:

As we know that air purifier is useful in deterring the toxins present in the indoor air. We mostly prefer to buy the popular brand air purifiers in India like Honeywell, Philips, Atlanta, Avizo, Ooze, Sharp purifiers etc.
Of all, Honeywell and Philips air purifiers rank top due to amazing features that help to improve the indoor air quality. But still, it’s tough to decide the best among both purifiers as they offer equal performance in cleaning the bad air.

The Honeywell air purifier has washable filters along with smart features like child lock, fan speed, sleep mode, indicators to completely eliminate the PM 2.5, dust particles and allergens. Whereas Philips air purifier is a budget-friendly device that uses Nano-protect filters+ sensing technology, to first sense the contaminants present in the room and then starts purifying the air.

Some Frequently Asked Questions About Air Purifiers

1. Is Air Purifier Bad For Health?

Not all air purifiers are good enough for your health. Some air cleaning purifiers that produce ozone gas can be harmful to people who have asthma or other respiratory problems. The ozone gases produced by air purifiers can cause respiratory tract irritation and breathing difficulty.

2. Do Air Purifiers Dehumidify?

Nope. Air purifiers don’t dehumidify the air present in the room. An air purifier circulates air through a filter which traps the impurities and pollutants. A humidifier sucks in the moisture and reduces the humidity levels in the air and kills the mold that thrives in moisture.

3. Do Air Purifiers Help You Sleep?

Apart from just allergen removal, air purifiers can help you sleep in several ways. Air purifiers can remove dust particles and other impurities that cause congestion which leads to improper sleep. Its soothing sound drowns out the outside noises that wake you up.

4. Do Air Purifiers Work For Allergies?

If you are allergies, air purifiers can be helpful in improving your condition. But it doesn’t mean that they can completely cure the allergy. It removes the dust, pollen and other allergens from the circulating air in the room which helps to breathe fresh air. But it doesn’t remove the allergens that are residing on the furniture or mattress.

5. Do Air Purifiers Cool The Room?
