Best Air Purifier For Home Under 17,000
If there is one Air Purifier we did not find a flaw in- its the Coway AP-1009. What a sleek design and performance! Air Intake from the front sides and bottom, and clean air is blown out from the cavity. Earlier to the arrival of Coway on the Indian arena, we used to recommend Philips AC2887. With Coway making a huge impact in the Indian Air Purifier market, we rate it No# 1. Just check out the reviews on Amazon and its ratings once.
The Coway Sleek Pro AP-1009 has an Auto mode which automatically controls the airflow. The fan speed is modulated according to the level of indoor pollution detected. Also, there are 4 beautiful Air Quality Indicator LEDs. There is a Filter change indicator when the filters need replacement. The air purifier can cater to a room size of 355 sq.ft. The company claims that the filters will last for over 8500 hours, but it varies. It’s sleek design occupies less floor space.
The Coway AP-1009 Air Purifier is the best choice. Just go for it if you want tension free air purification. Believe the reviews and ratings of thousands of content customers. Advice to monitor its price as on some days it is available for Rs.1000 lesser.
The Philips AC2882 Air Purifier is truly worth its price tag. It comes loaded with almost all features except for air quality display or mobile App. Its other variant AC2887 comes with an extra Real-time PM 2.5 display.
Philips AC2882 Air Purifier has a CADR of 333. The coverage area is close to 258~441 sq.ft or 24-41 m². As is quite apparent, this air purifier is best suited for larger sized rooms.
The Philips AC2882 Air Purifier has different operational modes. A General mode, an extra-sensitive Allergen mode, and an extra-powerful bacteria and virus mode.
Sleep Mode, Air Quality Indicator and Auto mode.
PROS and CONS
Philips AC2887 or AC2882 is the undisputed air purifier of choice. It is the optimum blend of right price, features, size and performance. Go for the cheaper AC2882 if you can do away with the absence of Real-time Air Quality Indicator meter.
The Samsung AX40K3020WU Air Purifier cannot be rated high for it’s looks. The design is simple with light Blue and Pink body. Just a pattern of curvy lines impart what can be deemed a “design”. We have definitely seen better looking & suave models. The dimensions are a bit bulky.
CADR and Coverage Area
Samsung AX40K3020WU Air Purifier has a CADR of 326. The coverage area is 419 sq.ft. As is quite apparent, this device is best suited for larger sized rooms.
The Samsung AX40K3020WU Air Purifier has 3-step air purification. It has a pre-filter and a compound filter with Activated carbon and PM2.5 filter combo.
Virus Doctor, Filter Replacement Indicator, Sleep Mode, Air Quality Indicator and Auto mode.
Philips AC4025 Air Purifier to cater to small spaces and low budgets. This purifier is meant for small rooms. Its coverage area is 323 sq.ft/30 sq.m nearly. The design and looks are proportional to the price and accordingly may seem a bit cheap as compared to the other higher range models. It has more or less the same functions and capabilities as AC4012.
The AC4025 model does not have a pre-filter, it has two filters- The activated carbon filter and HEPA filter.
Healthy Air Protect Alert, Step Fan Speed, 1/4/8 hours easy-to-set timer, Sleep mode.
Best Air Purifier For Home Over 20,000
Philips AC3256 Air Purifier is the Top Air Purifier over 20,000 range. Philips AC4372 looks stunning and works like a charm. If you can afford to spend more then Dyson Pure Cool Link Tower WiFi-Enabled Air Purifier.
This model from Philips is popular all over the world especially in Europe. It is a tall and powerful air purifier. Body is white with a black console and base. The Air Quality feedback is in the form of numeric display on the console. Not just this, there is a color changing LED provision in the cavity as well. The cavity is illuminated with different colors to indicate the Air Quality.
This model from Philips is the BEST Air Purifier in India for ASTHMA patients. The reason behind this trophy is the absolute torrent of air that its fan can generate. It’s air circulation is so good. An air purifier which can create good air circulation through it is automatically good. Its users have felt a marked decrease in the number of asthma episodes they used to suffer.
CADR 367 m³/h Coverage Area 800 sq.ft Power 11~60 W Noise Level 32.5~63.8 dB(A)
Dyson Pure Cool Link has an unusual design. Usually we see a small round cavity in the center of most models. But nearly all Dyson models have this huge circuitous one. This design has a cool reason behind it. The wide opening enables the device to achieve 90° wide reach. The purified air is blown far and wide just like a swing in an AC does.
A WiFi controllable mobile APP lets you monitor the air quality. To top it up a remote control is provided too. As we may have pointed out earlier, round air filters are also a plus. Round filters have a jet-engine type powerful fan inside. This design pulls in air from all directions in a 360° fashion. A circular base covers lesser floor area as well. No other air purifier gives so many speed levels as its 10! Overall it produces excellent air quality.

A very important thing to mention. Air Purifiers with very powerful fans suffer with high face velocity. What this means is- the design often is flawed one. The fan after a point starts blowing out the trapped particles from the filters. This can do more harm than good to your health. Dyson air purifier traps the pollutants in a vacuum sealed area. This, coupled with a low face velocity do the trick. The filters are densely packed so that the pollutants cannot escape through any region.
There are different Air Purifiers for different needs. Some perform especially well against any or all of the pollutants or odors. The below part specifically discusses Asthma. A powerful Air Purifier can also be considered good for Allergy. Find the Best Air Purifier For Asthma which give the most respite to its patients.
Best Air Purifier For Asthma In India
Do Air Purifiers combat the symptoms of Asthma? Air Purifier users must know that there are many types of air purifiers. They need to choose out the most suitable one. People with allergy, asthma, pet hair problem or need for odor control are different use cases. Chronic Bronchitis or hay fever is another ailment which can be relieved by air purifiers.
What is Asthma?
Asthma is a debilitating ailment which can put one’s life out of gear. Asthma symptoms usually hood up early in life but not necessarily so. According to an independent source, there are approximately 300 million asthma patients worldwide. About 30 million live only in India. Hence Asthma is a big problem. Asthma is a lungs disease which manifests itself in many symptoms. Problems like shortness of breath, wheezing, coughing and chest congestion are observed in Asthma patients. Hypersensitive Pneumonitis patients can benefit from air purifiers. Animal fur, molds, and fungus spores can cause this disease.
What Causes Asthma?
Our lungs are built up of a network of air tubes. Bigger airways open into smaller tubes and so on. Simply put asthma is an inflammation of these air passages. A lot of mucus is produced when the air tubes (bronchi) become narrow. This further aggravates the problem. This constricts the air transport capacity of the lungs as a whole. Exposure to stimuli by irritants can induce quick reactions. Mild responses may disappear on their own. But, violent ones often called Asthma Attack need specialized care.
This post is not intended to play down the importance of medicinal care. Medicines are indispensable to Asthma treatment and prophylaxis.
Asthma & Stress Correlation
The symptoms and impact of Asthma on life can be quite disturbing. Patients are constantly anxious at the back of their minds. One bad day or inadvertent exposure to irritants or allergens can spoil it. Hence, that asthma induces stress cannot be ruled out. Lifestyle changes focused on pulmonary health and strength can be beneficial. Practice Pranayam, Yog and aerobics under professional supervision.
Air Purifiers And Asthma Control
Air Purifiers can be a boon for asthma patients. You should keep your surroundings tidy and dust free. Keeping curtains, upholstery, pillows and surroundings clean can prevent asthma flare ups. Air Purifiers can keep a check on dust particles in the air. Dust Mites, molds and allergens thrive in furry cloths, furniture fabrics, carpets and coarse upholstery. Air Purifiers can remove dust, allergens, molds and mites. There is nothing better than keeping articles which come in your close contact absolutely clean. HEPA filters can trap and remove very fine particles from the air. Particles as small as 0.3 microns are effectively filtered out from air. Always ask and check for True HEPA filters before purchasing an Air Purifier.
Go for air purifiers with high circulation and CADR. Air purifiers with high fan speed and suction come in larger physical bodies. These are commonly the top-in-line in the catalog. Small air purifiers do not effectively combat asthma and allergy based diseases.
Hay Fever Or Allergic Rhinitis
Hay Fever is a common seasonal allergy which affects people the most during season change. It affects the respiratory tract and many Indians suffer from it. Running nose, incessant sneezing, itchy eyes, sinus congestion are some symptoms. Your body’s allergic response to pollen, fur, dust mites can be lessened using an ideal air purifier. Your Doctor would prescribe sprays containing Fluticasone Propionate or Azelastine Hydrochloride. Avoid these drugs and see if an air purifier for Allergies can give you the much needed respite?

Best Air Purifier Features and Reviews
A good Air Purifier is an utmost necessity for our homes and offices. However, one should strive to adopt practices to protect the environment so as there doesn’t fall any need for air purifiers. The earth is in its worst shape ever. Pollution is something which is more dangerous than terrorism if the number of deaths caused worldwide due to it is taken as a measure. In an estimate from WHO, some 4.6 million people die due to direct or in-direct exposure to pollution.
Pollution is a silent killer and its adverse effects show up slowly. Not to mention the plethora of ailments which show up as precursors of imminent death. Thus, its important to find ways and means to try to avoid pollution-the worst from of which is Air Pollution. Ever since the media has started reporting the worsening of Air-Quality index in News, people have come to notice the importance of Air Purifiers. Don’t want to go in the details ? Check best air purifiers.
What is an Air Purifier?
A majority of people spend most of their times in office or at home. Although commercial scale purifiers are available, but here we’ll discuss the more common ones- the one’s used in homes/offices or small, confined spaces. An Air purifier is a suction device which has in-built technology to filter the incoming air and remove pollutants. The so-called pollutants can be as chemical as harmful gases or as organic as pollen grains, mold spores or invisible mites which live on pets and bedding. Not all purifiers remove all the pollutants there are.
Air Purifier Filter Stages
A Pre-filter saves your costlier HEPA and carbon filters from bigger dust particles. A pre-filter arrests dust, pet hair, fine fabric strands from clogging the inner filters. It is in most cases washable.
The most common of the lot and by far the only type you’d have heard. It filters the contaminants based on the traditional principle of filtering- Make the air to pass through a filter/sieve with micrometer-sized holes. Well, that’s 1/1000000th of a meter! A TRUE HEPA purifier can achieve a 99.97% removal of particles; not smaller than 0.3 micrometers(Of course, it stops the bigger ones) and hence the name High-Efficiency Particulate Arrestance. These are mechanical air cleaners and rely on making the contaminated air to pass through the air filters. High efficiency runs in its name! Philips, Panasonic, MI, Sharp, Atlanta, Honeywell, Kent and BlueAir have excellent HEPA Air purifier options. Read the HEPA vs IONIZER post.
- Simple design yet if high grade filters (True HEPA) are used, they can be very efficient.
- No side-effects on health compared to purifiers employing Ionization or oxidation technologies
- HEPA Filters do not have the capability to remove gaseous pollutants. Pollutants like VOCs, bad-odors, smoke or chemical vapors and needs Activated Carbon filters.
- Not Washable so you need to replace them when Filter Replacement Indicator asks.
- May prove ineffective incase your device uses poor quality or low grade HEPA filter.
Activated Carbon Filter
Activated Carbon is a powerful agent for adsorption of gaseous pollutants. So, Activated carbon traps VOCs and poisonous gases inside the enormous surface area its pores hold. A pound of activated carbon has a surface area of a football field! An Activated carbon filter should also not be washed. Rather it can be exposed to sunlight to warm it up. This method helps release the trapped gases and recharges the carbon.
Ozone and Ion Generators
Some Air Purifiers employ additional stages like Ion Generators or Ozone Generators. Ion Generators produce charged particles called ions mostly negatively charged. Negative ions or anions are known to be mood enhancers. Also, anions react with pollutants and convert them into harmless byproducts. Some Ion generators can produce Ozone gas. Do check whether there is any ozone production or to what level. Higher ozone concentration is known to be harmful for humans. Ozone generators are passe now and hardly any air purifier uses this technology now. Ozone is a known oxidizing agent and thus kills bacteria and pathogens.
Best Air Purifier Buying Considerations Guide
Chances are that you have made up your mind that you definitely need an air purifier for your home or office spaces. Before you venture out in your search for the ideal device, you must prepare a checklist. Here we’ve compiled an exhaustive checklist which you can take clues from.
Home/Office Use or HVAC Scale
The place where you’re gonna use the air purifier is an important consideration. The size of your rooms and the extent of pollution in air impacts the choice. You may be proud of the hygiene and the cleanliness that you maintain in your kitchen, but the reality may be a stark contrast. Majority of the cooking chores release colorless fumes of pollutants not to forget a variety of smells and odors. Things may turn really ugly in poorly ventilated spaces. Gases like Carbon monoxide abound in insufficiently aerated and confined spaces and where combustion is taking place.
The conventional gas stove releases carbon monoxide, nitrogen dioxide, particulate matter and other fumes. Consider replacing them with electric stoves. If there are restrictions which limit proper ventilation get a chimney installed. A chimney cannot be very effective because fans and gusts of air still circulate the polluted air within the home. Cigarette smoke may also be a major contributor of air-borne pollutants. The best remedy is to adopt recommended best practices and install an air purifier with mandatory activated carbon and HEPA filters among other filter types.
Offices although are much cleaner than our kitchen areas so to speak, but other type of pollutants abound there. Many people work in offices and they are not always healthy. Needless to state it is highly probable that many of them are vectors of bacteria and viruses. The vast expanses of office furniture and electronic devices are sources of TVOCs, Formaldehyde, Toluene, and other organic gases. Air Purifiers with large coverage area, high fan speeds and prolonged filter lives should be employed in offices. Air Purifiers can be installed in HVAC (Heating, Ventilation and Air Conditioning) systems too. For homes or offices with centrally air conditioned provisions, this can be a quick, cost effective and convenient way of tackling with pollution.
Decide Your Budget
Perhaps the only thing that really matters is how much money you are willing to shell out for an Air Purifier. This amount is directly proportional to the size of the problem (Read area, pollution levels and diseases or allergies). You can get a functioning air purifier for rooms in as low as INR 5,000 and this figure can easily scale to over INR 50,000. The cost depends on the CADR (Clean Air Delivery Rate), the number of filters in the machine, the range of air flow, the primary technology used for air purification (VitaShield IPS, Nanoe etc), add-on features pertaining to different modes of operation and comfort and not to forget the durability of the filters.
Go For The Middle!
We would suggest to always go for the mid-segment models of air purifiers from any company of repute. So, why are we dissuading you to desist from buying the top notch models? The answer is simple, spend only that much for which you do not have to repent later. Its not that those “top” purifier models have any flaws per se, it’s more in the running and maintenance cost incurred in the short term and long term (filters cost more etc.) as well. If your requirement is such that you want large coverage area, then that’s a different case. For an average use case always prefer the mid or lower segment air purifiers.
Purpose Of Buying the Air Purifier
Are you purchasing the Air Purifier hoping it to remedy some specific disease or problem? Is there anyone with allergies or other respiratory diseases in the home? Does someone in the house falls ill when seasons are changing? Or, if anyone sneezes incessantly when Pollen grains abound in the air? Do you live in a warm and humid environment where molds and fungi flourish? Then an Air Purifier with Ionizer would suit you. Do you have pets in the house? If Yes, you’d know of those months when every square foot of the house has their fallen hair. Does the place where you intend to place the air purifier have scope for sealing it out from the outside environment? These are some of the questions you should find the answers for before venturing out to buy an Air Purifier.
How To Select the Right Air Purifier
Once you have found the answers to the questions listed above, you have made good progress already. Now is the time to look out for the finer details in the actual product. Below, we have listed out the features you should diligently seek in an air purifier.
A High CADR Rating
The Clean Air Delivery Rate or CADR is the most commonly quoted value. If you have to make a choice between air purifiers with different CADR ratings, go for the one with the higher one. Although ACH (described below) is more important. CADR rating is a reliable indicator of the “cleaning” prowess of the air purifier. How much CADR should your Air Purifier have? Simply calculate the room volume in cubic feet. Now, multiply the CADR rating by 12. The result should be greater than your room’s volume.
ACH (Air Changes per Hour)
ACH value denotes the number of times the air inside the room has passed through the filters. The volume of the room is important in ACH calculation. By default, an air purifier makes around 5 complete air changes (5x ACH). Along with a high CADR, an air purifier must have a ACH value greater than 4. For home and office, a 5x ACH rating suffices while a 8x ACH rating is suitable for commercial use like in shops near polluted roads etc. For industrial and health facilities like hospitals an air purifier with an ACH rating upward of 10 should be employed.
More The Stages of Filtration The Better
Air Purifiers come with 2 to 7 stages of filtration. Each stage employs a different set of filters or mechanisms to clean a targeted pollutant from the air. Sometimes there are multiple layers of the same filter like mostly seen for HEPA filters. The more the stages, the more probable it is that the air purifier will succeed in its operation. Pre-Filter, Anti Bacterial Filter, HEPA filters, Activated Carbon Filter, Photo Catalyst, UV stage and ionizer stage is an example of 7 stage filtration. Some models have ionizers as the last stage before clean air is egress. In all likelihood, the ionizer would be a precipitator one and not the ion spewing generator type which you should avoid.
The sensors are an integral part of air purifiers without which it would lose all its intelligence. Sensors co-ordinate the working of the air cleaner in many ways than one. Air Quality Sensors record the pollution levels in the air. Depending on the pollution levels the air purifier changes its fan speed correspondingly. Then there are particle sensors which are synonymous with the air quality sensors. Specialized PM2.5 sensors and indicators display the level of dangerous PM2.5 particles. Technologies like AeraSense and EcoNavi are based on sensor functions and also employ heuristics for better efficiency. Similarly, light sensors sense when the ambient light intensity changes. Light levels dictate how the air purifier alters its operation during Sleep or Night mode. Odor sensors quickly detect foul odors and adsorb them. All in all, more is the variety of sensors the better it is.
In today’s scenario when artificial intelligence and IOT (Internet of Things) are gaining ground. You would not want your air purifier to be dumb. Turbo Mode (different brands of purifiers may have a different name of it) when the fan speed is the highest is a useful feature. You must be able to control the sensitivity of the air purifier. In other words, how responsive you want it to be against the pollutant composition of the room. You must see functions for setting timers and adjust the fan speed levels. Child lock is also a good thing to have when you have little tots around. Spot Air and Swing functions along with 3D air circulation are good to have.
Filter Replacement Indicator
Your Air purifier should alert you in advance when it deems it necessary to clean the filters or replace them. Some basic air purifiers show color code indicators to detect filter health which need to be manually monitored.Most models now have dedicated filter health check mechanisms and indicators. Many air purifier models now cease to function if you ignore its warnings and continue to use a dirty set of filters. It is always convenient if there are Pre-Filters which you can detach and clean yourself. Having Pre- Filters extend the life of the inner costlier filters as they trap the bulk of the larger sized particles. Pre-Filters can be cleaned under running tap or vacuum cleaned.
Air Purifiers are not power guzzling appliances and most models limit their power hunger to under 70 Watts. It means if you are extra conscious of your bills, don’t sweat. An air purifier would not change your monthly expenses much. Still, you can always refer to the power specifications which is easily available. You can check the product manuals or labels for Energy Star certified air purifiers which guarantee savings and efficiency. A standard room air purifier, operating continuously, uses approximately 550 kWh per year in electricity. This is more than the energy used by some new refrigerators!
ENERGY STAR certified room air purifiers are 40% more energy-efficient than standard models, saving consumers about 225 kWh/year and $30 annually on utility bills. Different countries may have different such agencies though. The more is the CADR/Watt ratio, the higher would the air purifier rate in Energy Star ratings. Certifications from ECARF and AIRMID are also good to have. Always read the product manual for instruction on placing the air purifier for optimum placement.
Most brands are conscious of the portability of their appliances, yet it is worthwhile to still check for it. After all, the device you buy would have to be moved around sometimes. Generally, air purifiers are not heavier than 8 Kilograms. If yours is heavier, then see whether caster wheels are pre-installed or not. Some air purifiers are wall mountable, which may prove to be a blessing for the households with space crunch. Also, check for the power cable/cord length which is usually 1 m. Look for strong handles as some models have them.
We know that making the right decision when it comes to buying an air purifier can be a daunting task. We hope the points we have highlighted would help you in making an informed decision. Don’t trust any information blindly and always do a thorough check and analysis. The Best Air Purifier for you may not prove useful for some other home. Hope you read this post carefully! You should now be in a better position to purchase the ideal air purifier for your home 🙂 Be Prepared that the filters will need maintenance and even replacement. So, be ready to shell out more money. Using an expired set of filters is injurious to health.
