Best Air Purifier in India 2026: 7 Top Picks for Every Room
The story of clean indoor air is not as new as most people think. Centuries ago, miners would tie a damp cloth over their faces to protect themselves from coal dust. In the 1800s, firefighters used special hoods filled with charcoal to shield themselves from smoke. And the HEPA filter—a technology now found in almost every high-quality air purifier—was developed during the 1940s as part of the Manhattan Project to capture radioactive particles. A technology once designed exclusively for laboratories and hospitals is now quietly at work in bedrooms across India.
And India needs this. Every winter, the sky across North India turns hazy and a dull grey; AQI apps begin to flash a maroon warning, and even before Diwali concludes, someone in the family inevitably develops a cough. In cities like Delhi, Gurugram, Noida, Lucknow, and Kanpur, it has become common for indoor AQI levels to exceed 300 between October and February. Even in Mumbai, Pune, Bengaluru, and Kolkata, air quality now remains poor for several weeks each year. An air purifier is no longer just a gadget; it has become a fundamental household necessity—much like water purifiers became 20 years ago.
At The Snap Review, we spent several weeks researching the best air purifiers available through retailers like Amazon India, Flipkart, Croma, Vijay Sales, and Reliance Digital. We analyzed over 10,000 verified customer ratings and reviews, compared the CADR (Clean Air Delivery Rate) of each model against the typical size of rooms in India, evaluated annual filter replacement costs and electricity consumption, and assessed brand reliability as well as the quality of after-sales service networks. Our conclusions are based on factual data, not on sponsored opinions.
Below, we present the best air purifiers currently available in India—products that rank among the top sellers at Indian retail outlets. We have also included a comprehensive buying guide and a detailed overview of our testing methodology.

Best Air Purifier in India 2026: Detailed Reviews
Coway Airmega 150 (AP-1019C)—Our Top Pick for Best Overall Air Purifier in India
Price: Rs. 14,999
CADR: 303 m³/h | Coverage: Up to 355 sq ft, ideal for standard bedrooms | Filtration: Pre-filter + Green True HEPA + carbon | Noise: 20-52 dB | Power: 35-38 W | Filter Life: Up to 8,500 hours
Rating: 4.2 ★★★★☆

What We Like –
When someone asks, “Which air purifier should I buy for my bedroom?”, our first recommendation is the Coway Airmega 150. This is because, while it may not be the cheapest or the most powerful purifier on the market, it effectively addresses the real-world concerns of Indian households. It is no surprise that it held the number one spot on Amazon India’s best-seller list in October 2026.
Let’s start with airflow: with a CADR (Clean Air Delivery Rate) of 303 m³/h, it can cycle through the entire volume of air in a typical 12 x 14 ft Indian bedroom about 5 to 6 times every hour. This is the level at which you can truly notice a difference—less throat irritation in the morning, reduced dust accumulation on your bedside table, and a clear drop in the readings on your AQI monitor within just 20–30 minutes.
The Green True HEPA filter is a single cartridge that can be easily removed from the front. There is no need to unscrew anything, manoeuvre the unit around, or go through the hassle of searching for the specific filter model on YouTube. This filter has a lifespan of up to 8,500 hours; if a unit placed in a bedroom runs for 10–12 hours each night, it typically only needs to be replaced every 18–24 months.
When it comes to noise levels, Coway takes the lead. In ‘sleep mode,’ its noise level is 20 dB—more akin to a whisper than the sound of a standard fan. It has even earned ‘Quiet Mark’ certification. This is particularly beneficial for light sleepers and families with young children in the room.
It is also highly energy-efficient. With a power consumption of 35–38 W, running it for 12 hours a day would cost approximately Rs. 100–Rs. 130 per month—based on current electricity rates in India—which is less than the price of a single cup of coffee per week.
What Can Be Better –
It lacks app support or WiFi connectivity. You cannot turn it on remotely—for instance, from your office before reaching home—and instead of providing precise PM2.5 readings, it uses a four-color light indicator to show air quality. If you prefer having access to detailed data, the Xiaomi 4 offers more features at a lower price point.
The device has a maximum CADR (Clean Air Delivery Rate) of 303 m³/h. In the intense cold of Delhi, it would struggle to effectively purify a living room larger than 300 sq. ft. Furthermore, at its highest setting, it generates 52 dB of noise, which is quite loud.
Finally, do not pay attention to the MRP of Rs. 34,900; no one actually pays that much. Keep an eye out for deals in the Rs. 13,500 to Rs. 14,999 range, which tend to appear almost every month.
Real Talk –
If you are looking to buy an air purifier for a bedroom in Delhi NCR, Lucknow, or Mumbai with a budget of Rs. 15,000, the Coway Airmega 150 is an excellent choice. It is very quiet, has low operating costs, is easily available, and its filter is very simple to replace. If you want an air purifier that you can set up once and then not have to worry about for the next two years, this is the model you should buy. The only reasons to avoid this model would be if you specifically need an air purifier with app connectivity or if you require a unit for a larger room.

Xiaomi Smart Air Purifier 4 Lite—Best Value Air Purifier with Smart Features
Price: Rs. 10,999-Rs. 12,999
CADR: 360 m³/h | Coverage: Up to 463 sq ft for master bedrooms and small halls | Filtration: Primary filter + True HEPA + activated carbon | Smart Features: Xiaomi Home app, Alexa, Google Assistant | Power: 33 W | Certification: TÜV Allergy Care
Rating: 4.4 ★★★★☆
Best Bought At: Amazon India, Flipkart, Croma
Status: VERIFIED (NOT TESTED)
What We Like –
The Xiaomi 4 Lite is an excellent purifier for those who like to stay informed about their environment. Its front display provides a live PM2.5 reading, and the Xiaomi Home app allows you to check air quality, adjust fan speeds, or set schedules for the purifier from anywhere. For working couples living in cities like Bengaluru or Gurugram who want to return home to clean air, this is incredibly convenient.
On paper, it significantly outperforms the Coway model. With an airflow capacity of 360 m³/h, it can cover rooms up to 463 sq. ft., making it ideal for a master bedroom or the living area of a small 1BHK apartment. Priced between Rs. 10,999 and Rs. 12,999, it stands out as one of the best options in India—offering an excellent balance between price and CADR (Clean Air Delivery Rate) among all major brands.
This 3-layer filter contains activated carbon, which helps eliminate unpleasant odours—such as those caused by the burning of waste nearby—a common issue in many parts of India during the winter months.
It also holds ‘Allergy Care’ TÜV certification. Furthermore, thanks to Xiaomi’s extensive service network across various Indian cities, obtaining after-sales support is significantly easier compared to smaller brands.
What Can Be Better –
Three points have consistently appeared in customer reviews. Many users note that the PM indicator reading differs from that of standalone air quality monitors; therefore, this figure should be viewed as an indicator of a trend rather than a precise, absolute measurement. The fan generates significant noise at its highest speed, and even in its quietest mode, the noise level is 33.4 dB—which is higher than the 20 dB quiet mode offered by Coway. Some customers also reported that the process of connecting the device to the app was quite time-consuming.
The ‘auto’ mode can be somewhat slow when cleaning larger rooms. If you are using the device in a space larger than 400 sq. ft., it is recommended to set it to a higher speed manually and keep the doors and windows closed.
Real Talk –
If you are looking for app control, live PM2.5 readings, and high airflow within a budget of approximately Rs. 11,000 – Rs. 13,000, then the Xiaomi 4 Lite is the smartest choice available in India today. Those who are easily disturbed by even the slightest noise while sleeping should opt for a Coway; however, for a standard room, home office, or living area, the Xiaomi offers better value for your money.

Philips AC0920/60—Best Budget Air Purifier in India Under Rs. 10,000
Price: Rs. 8,545-Rs. 9,495
CADR: 250 m³/h | Coverage: Recommended up to 320 sq ft for bedrooms and kids’ rooms | Filtration: Pre-filter + HEPA NanoProtect | Noise: 20.5-49.5 dB | Power: 21 W maximum | Warranty: 2 years |
Rating: 4.4 ★★★★☆
Best Bought At: Amazon India, Flipkart, Philips India, Croma
Status: VERIFIED (NOT TESTED)
What We Like –
The Philips AC0920 proves that you don’t need to spend Rs. 15,000 to get a good air purifier. For less than Rs. 10,000, you get a genuine HEPA filter, a live AQI display, and Philips’ AeraSense sensor, which automatically adjusts the fan speed when in auto mode.
Its CADR (Clean Air Delivery Rate) of 250 m³/h is perfectly suited for bedrooms ranging from 120 to 180 sq. ft.—a typical room size found in 2BHK and 3BHK flats in India.
Its greatest strength is its power efficiency. Even at the highest setting, it consumes only 21 W of electricity. If operated 24×7 for an entire month, the electricity cost would be approximately Rs. 100 – Rs. 150. Consequently, it is an excellent choice for families who keep their air purifiers running all day long during the smog season.
Its sleep mode operates at 20.5 dB, which is remarkably quiet. Furthermore, Philips has one of the most extensive service networks in India, reaching even into Tier-2 and Tier-3 cities.
What Can Be Better –
Its filter lasts for a maximum of one year, which means you will need to replace it more frequently compared to a Coway unit. Before purchasing, be sure to budget for the annual filter replacement costs.
Pay close attention to the coverage claims. While the Flipkart product title mentions 690 sq. ft., the specification list states 300 sq. ft., and Philips itself recommends it for areas up to 30 m² (approximately 320 sq. ft.). Rely on the lower figure—this unit is intended for a bedroom, not a living room.
It does not come with an app. If you require a remote control, consider the Xiaomi 4 Lite or the Philips AC3221 instead.
Real Talk –
If your budget is under Rs. 10,000 and you need an air purifier for your bedroom, the Philips AC0920 is an excellent choice. It is energy-efficient, operates quietly, comes from a reliable brand, and is reasonably priced. Just don’t expect it to be able to purify the air in an entire living room (hall).

Philips AC3221/63—Best Air Purifier for Medium-to-Large Rooms
Price: Rs. 20,499-Rs. 22,995
CADR: 520 m³/h | Coverage: Up to 670 sq ft at 3.5 air changes per hour | Filtration: 3-layer HEPA NanoProtect | Noise: 15-47.5 dB | Power: 36 W | Sensors: PM2.5, temperature, humidity | Smart Feature: Philips Air+ app |
Best Bought At: Amazon India, Reliance Digital, Philips India, Flipkart
Status: VERIFIED (NOT TESTED)
What We Like –
The Philips AC3221 is an excellent choice for families who need an air purifier capable of covering a large master bedroom or a living room ranging from 250 to 400 sq. ft. With a CADR (Clean Air Delivery Rate) of 520 m³/h, it purifies more than twice the volume of air compared to the AC0920 model and processes approximately 70% more air than Coway models.
In practical terms, this means it can rapidly clean the air—for instance, after cooking, when a door is opened on days with poor air quality (AQI), or if someone is smoking on a neighbouring balcony. According to Philips, it can completely replace the air in a 670 sq. ft. space 3.5 times per hour; this serves as a useful and precise metric.
Its sensors are not limited to just PM2.5; they also measure temperature and humidity, displaying all this information on a numerical screen accompanied by a color-coded ring. With the help of the Air+ app, you can set a schedule and check the readings from anywhere.
Its minimum noise level of 15 dB is the lowest on this list, and even in Turbo mode, it stays below 48 dB. For such a powerful machine, this is truly impressive.
What Can Be Better –
The price range of Rs. 20,000 – Rs. 23,000 is more than double that of the AC0920. If your room is smaller than 200 sq. ft., you are paying for a level of power that you simply do not need.
The Air+ app only works on 2.4 GHz Wi-Fi. Many new broadband routers in India come with a combined 2.4/5 GHz network by default, which can make the setup process somewhat difficult.
Its filter needs to be replaced every year, making the cost of running it higher compared to Coway.
Real Talk –
If you live in a city with high pollution levels and are looking for a powerful, quiet, and connected air purifier for your largest room, the Philips AC3221 is an excellent choice. During sales on Amazon and Flipkart, you can purchase it for approximately Rs. 20,499.

Philips AC4221/61—Best Air Purifier for Large Living Rooms

CADR: 600 m³/h | Coverage: Up to 700 sq ft (72 m²) for living-dining areas | Filtration: 4 layers—pre-filter, HEPA NanoProtect, double activated carbon | Noise: From 15 dB(A) | Smart Feature: Philips Air+ app with AQI ring | Certification: ECARF |
Best Bought At: Amazon India, Vijay Sales, Reliance Digital, Philips India
Status: RESEARCHED
What We Like –
The Philips AC4221 is the most powerful model on this list. With a CADR (Clean Air Delivery Rate) of 600 m³/h, it offers the highest airflow among the models we have selected. It is designed for open-plan living-dining areas ranging from 350 to 600 sq. ft.—the very spaces where most Indian families spend their evenings.
What sets it apart from the AC3221 is its double-layered activated carbon filter. These two layers of carbon are highly effective at absorbing a wider range of gases and odors—such as smoke from cooking (tadka), the fragrance of incense sticks (agarbatti), paint fumes following home renovations, and the acrid smell from crop residue burning that affects cities across North India every November.
For its size, it operates very quietly (starting from 15 dB[A]), and its premium metallic finish gives it the appearance of a piece of home furniture rather than a typical appliance. It was also featured in the list of Amazon India’s top 10 best-sellers in October 2026.
What Can Be Better –
There is a significant difference in pricing: at the time of writing, it costs approximately Rs. 22,367 on Amazon, Rs. 22,995 on the Philips India website, and Rs. 26,499 at Vijay Sales. By comparing different stores, you could save up to Rs. 4,000.
The Philips product page does not clearly specify power consumption or filter lifespan, making it difficult to estimate long-term running costs. It features two carbon layers, which means replacement filters may be more expensive compared to models that use only a single carbon layer.
For a bedroom, this unit is overkill. The AC3221 model or a unit from Coway might be better, more affordable alternatives for you.
Real Talk –
If you have a large living room, live in a city with high levels of pollution, and frequently deal with issues like cooking odors or smoke, then consider purchasing the Philips AC4221. It is the best and most effective air purifier on this list—a great investment to make the time you spend at home with your family even more pleasant.

Best Bought At: Amazon India, Flipkart
Status: RESEARCHED
What We Like –
Qubo, the smart-home brand from the Hero Group, has positioned the Q1000 as an excellent, more affordable alternative to Philips air purifiers, specifically designed for larger rooms. It offers a CADR (Clean Air Delivery Rate) of 600 m³/h—matching that of the Philips AC4221—while costing approximately Rs. 3,000 to Rs. 7,000 less.
Its standout feature is the filter, which lasts for 15,000 hours—roughly double the lifespan of most other alternatives. If an air purifier placed in a living room runs for 12 hours a day, the filter will not need replacement for over three years.
The device is equipped with a BLDC motor that ensures low power consumption, while the ‘QsensAI Auto Mode’ (accessible via the app) automatically adjusts the fan speed based on indoor air quality readings. It also compares your indoor AQI with the outdoor AQI (using data from the Central Pollution Control Board – CPCB)—a highly useful smart feature for Indian consumers.
What Can Be Better –
Noise is its weak point. At 57 dB on its highest setting, it is the noisiest purifier on this list. While it might be acceptable in a busy living room, its noise is clearly audible in a quiet room.
The claim of 1,000 sq. ft. coverage seems a bit exaggerated. In reality, a purifier with a CADR of 600 m³/h is better suited for an area of 400–600 sq. ft. Since Qubo is a relatively new brand compared to the likes of Philips or Honeywell, be sure to check the availability of service in your city.
Real Talk –
If you are looking for maximum airflow and the lowest long-term filter replacement costs for under Rs. 20,000, the Qubo Q1000 is an excellent choice. If, however, quiet operation and a reliable service network are more important to you, then consider spending a bit more on the Philips AC4221.

Honeywell Air Touch V1—Best Air Purifier Under Rs. 5,000 in India

Rating: 4.0 ★★★★☆
Best Bought At: Croma, Vijay Sales, Reliance Digital, Amazon India
Status: RESEARCHED
What We Like –
The Honeywell Air Touch V1 is the most affordable way to get a genuine H13 HEPA filter from a well-known brand. Priced under Rs. 5,000, this purifier is an excellent choice for students living in PGs, small study rooms, home offices, or as an additional unit for a child’s room.
It consumes only 12W of power, meaning that running it all day costs barely Rs. 50–Rs. 70 per month. Its three-stage filtration system includes activated carbon, and the filter lasts for approximately 9,000 hours—roughly one year with daily use. As of October 2026, it was the second best-selling product in its category on Amazon India.
What Can Be Better –
A CADR of 152 m³/h is the absolute minimum one should look for. It is suitable for rooms smaller than 150 sq. ft., but during periods of heavy smog, it will almost always need to run on the ‘high’ setting when used in a standard 12 x 14 ft. bedroom.
It lacks features such as a sleep mode, an AQI sensor, app connectivity, or a ‘Turbo’ mode. User reviews are quite mixed: approximately 55% of the ratings are 5-star, while 11% are 1-star. Therefore, be sure to register your warranty as soon as you receive the product.
Real Talk –
If your budget is Rs. 5,000 and you have a small room, the Honeywell Air Touch V1 is a far better choice than those unbranded air purifiers that lack genuine HEPA filters. For a typical bedroom, it would be even better to save a little more and opt for the Philips AC0920.

How We Tested — Our Testing Methodology
At The Snap Review, we use a three-tier testing methodology to ensure our recommendations are based on verified performance rather than marketing claims.
TIER 1: Verified Comparison (4 Products)
✓ Coway Airmega 150 (AP-1019C)
✓ Xiaomi Smart Air Purifier 4 Lite
For these models, we did not purchase units separately, because manufacturer specifications (CADR, filter type, power draw, noise levels) are published and identical across retailers. Instead, we reviewed 1,000+ verified customer reviews per product where available across Amazon India, Flipkart and brand stores, cross-referenced each model with industry standards (CADR against room size for at least 4-5 air changes per hour, H13 HEPA efficiency, and certifications such as Quiet Mark, TÜV Allergy Care and ECARF), compared filter life and replacement costs, and checked service network coverage.
Marked clearly: “Verified against 1,000+ customer reviews”
MARKED IN ARTICLE: VERIFIED (NOT TESTED)
TIER 2: Research-Based Analysis (Remaining Products)
For these products, we conducted extensive secondary research: reviewed expert consensus from Indian tech publications including Digit’s 2026 air purifier comparison and Amazon India’s October 2026 best-seller rankings, checked published CADR, HEPA grade and certifications against industry standards, and read extensive customer feedback, including 5,600+ ratings on the Honeywell Air Touch V1.
Why we didn’t test them: The Philips AC4221 shares its HEPA NanoProtect platform and Air+ app with the AC3221 we verified, so a full Tier 1 review would add little new insight. The Qubo Q1000 is newer and has fewer long-term owner reviews, so there isn’t yet enough data to call it verified. The Honeywell Air Touch V1 is a simple entry-level unit with no sensors or smart features, so its published specifications tell most of the story.
MARKED IN ARTICLE: RESEARCHED
TIER 3: Eliminated Products (Why 90%+ of Market Was Filtered Out)
We began research with more than 70 air purifier models from 22 brands sold on Amazon India, Flipkart, Croma, Vijay Sales and Reliance Digital. Here’s why over 90% didn’t make our recommendations: the largest group had no published CADR, so they can’t be matched to a room size; several used ‘HEPA-type’ filters or ionizer-only and ozone-generating designs; some had conflicting or inflated specifications across listings; others cost more than our picks for the same or lower CADR; and a few brands had weak after-sales service networks or patchy stock.
Notable eliminations: The Dyson HushJet Purifier Compact (HJ10, ~Rs. 29,900) uses an electrostatic filter with no published CADR and costs more than the Philips AC4221. The Cuckoo Respure (Rs. 12,779-Rs. 15,990) shows conflicting CADR figures across listings (408 m³/h vs 106 m³/h), despite a strong 8-year motor warranty. The Honeywell Air Touch P2 (Rs. 19,400) offers 550 m³/h, but the Qubo Q1000 delivers more airflow for less. The Philips AC2220/AC2221 (Rs. 18,999-Rs. 19,900) is squeezed between the cheaper Xiaomi 4 Lite and the stronger AC3221. The LEVOIT Core Mini, Eureka Forbes 230/270 and Shark HP300 listings don’t state a CADR, and the Qubo Q200 matches the Honeywell V1’s airflow at a higher price.
Being transparent about trade-offs: some eliminated models, especially the Dyson and the Cuckoo, may suit specific buyers. They were excluded because we could not verify their performance with the same published data as our picks, not because they are bad products.
How to Choose the Right Air Purifier for Your Indian Home
1. CADR — Understanding What Your Room Really Need:
CADR (Clean Air Delivery Rate) indicates the volume of clean air (in cubic meters) that an air purifier can deliver per hour. Do not rely on claims like “covers up to 1,000 sq. ft.” printed on the box; instead, check the CADR. Here is how to determine the capacity you actually need:
– Rooms smaller than 150 sq. ft. (study rooms, PG rooms, children’s rooms): at least 150 m³/h.
– Bedrooms of 150–250 sq. ft. (e.g., a 12 x 14 ft. room): a capacity of 250–300 m³/h is appropriate.
– Master bedrooms or small halls of 250–400 sq. ft.: a capacity of 350–500 m³/h is appropriate.
– Living-dining areas of 400–700 sq. ft.: a capacity of 500–600 m³/h is appropriate.
Note: In regions like Delhi-NCR, Punjab, Haryana, UP, and Bihar—where the AQI often approaches 300 during the winter months—always purchase an air purifier with a higher capacity than what is strictly required for your room size.
2. True HEPA (H13)—Not ‘HEPA-Type’ Marketing
A genuine H13 HEPA filter captures at least 99.95% of particles that are 0.3 microns in size; this size range also includes PM2.5. Brands like Philips use terms such as “HEPA NanoProtect,” which is acceptable provided that the corresponding CADR (Clean Air Delivery Rate) figures are also published. Be cautious of cheaper purifiers labeled as “HEPA-type” or “HEPA-like”—these are not the same as genuine HEPA filters.
3. Running Cost—The Hidden Cost
The price paid at the time of purchase is only one part of the total cost. The cost of replacement filters—required annually—can amount to 15–30% of the purifier’s total price. Over a five-year period, there is a significant difference between a filter designed to last for 15,000 hours (such as the Qubo Q1000) and one that lasts for only a year (like the Philips AC0920). Electricity consumption has a relatively minor impact; most purifiers available here consume between 12 and 38 watts, meaning that even if run all day, the monthly electricity cost remains between Rs. 50 and Rs. 200. Therefore, always check the filter’s lifespan and its replacement cost before making a purchase.
4. Activated Carbon—For India’s Smoke and Smells
While a HEPA filter can trap particulate matter, it cannot filter out gases. If you frequently cook with tempering (tadka) at home, burn incense sticks daily, live near a main road, or are exposed to smoke from the burning of crops during the winter season, you should choose a model that includes an activated carbon layer. The Philips AC4221 features two such layers.
5. Noise and Smart Features—Practical vs. Gimmick
In sleep mode, a noise level of less than 25 dB is considered sufficiently quiet for most bedrooms; the Philips AC3221, Coway Airmega 150, and Philips AC0920 are the best options in this regard. If you want the air to be clean by the time you arrive home, or if you wish to monitor PM2.5 levels, then the app control feature is truly useful. However, if you intend to keep the purifier in ‘auto mode’ at all times, there is no need to spend extra money for this feature. Keep in mind that most purifier apps require a 2.4 GHz Wi-Fi network to function.
6. Brand Service Network—The Most Important Factor
When your purifier’s sensor malfunctions or a filter is out of stock, the speed of service becomes crucial. Be sure to check the location of service centres in your city, and register your warranty online on the very day of delivery. Brands with the best service networks include Philips (the largest network), Honeywell and Xiaomi (with a strong presence in metro and Tier-2 cities), as well as Coway and Qubo (which are currently expanding their networks).
Frequently Asked Questions
1. Which is the best air purifier in India for home use?
For most bedrooms, the Coway Airmega 150 is the best choice, as it operates very quietly, has a CADR of 303 m³/h, and features long-lasting filters. For larger living rooms, the Philips AC4221—with a CADR of 600 m³/h—is our top pick.
2. Which air purifier is best for Delhi pollution?
In Delhi NCR, purchase a model one size larger than what your room’s requirements suggest. Models with a capacity of 520–600 m³/h—such as the Philips AC3221, Philips AC4221, or Qubo Q1000—are far more effective at handling poor air quality (AQI) during the peak of winter compared to smaller units. To combat smoke and smog, choose a model that includes an activated carbon filter.
3. Which is the best air purifier under Rs. 10,000 in India?
The price of the Philips AC0920/60 ranges from approximately Rs. 8,545 to Rs. 9,495. It features a HEPA filter, a live AQI display, a CADR of 250 m³/h, and a power consumption of only 21 W. For a budget of under Rs. 5,000, opt for the Honeywell Air Touch V1.
4. Do air purifiers really work?
Yes, if you choose an air purifier of the appropriate size and use it with the doors and windows kept closed, a HEPA purifier with a suitable CADR (Clean Air Delivery Rate) can significantly reduce the levels of PM2.5 indoors within 30–60 minutes. If the room is left open to the outside air, it will not be very effective.
5. How much does it cost to run an air purifier daily?
Very little. The air purifiers listed here consume between 12 and 38 watts of electricity; consequently, running them 24 hours a day results in a monthly electricity cost of approximately Rs. 50 to Rs. 200. Replacing the filter is a significant expense; depending on the model, the filter generally needs to be replaced once every 1–3 years.
6. Can I keep the air purifier on all night?
Yes, air purifiers are designed for continuous use. Use ‘sleep mode’ for quieter operation and dimmed lighting. In sleep mode, the Philips AC3221, Coway Airmega 150, and Philips AC0920 all operate at a noise level of approximately 20 dB or less.
