Whether you’re protecting your kids from allergens, fighting cooking odors in your kitchen, or just want cleaner air while working from home, one of these Coway air purifiers will fit your needs perfectly.

The 3 Best Coway Air Purifiers You Can Buy Right Now
After extensive testing and comparing customer feedback from over 9,000 verified buyers, here are my top picks that’ll actually make a difference in your home’s air quality.
1. Coway Airmega 250 (AP-1720H) – Best Overall Air Purifier for Indian Homes EDITOR’S CHOICE
Quick Specs
- Coverage Area: 930 sq. ft. (cleans in 30 minutes)
- Filter Type: Anti-Virus True HEPA H13 + Deodorization
- Particle Efficiency: 99.999% removal of 0.01-micron particles
- Filter Life: 8500 hours (approx. 1.5-2 years)
- Noise Level: 22 dB (whisper-quiet)
- Warranty: 7 years on motor + 1 year electrical
Why the Airmega 250 Stands Out
This is hands-down the best air purifier for large Indian homes, especially if you’re dealing with Delhi’s notorious pollution. The Airmega 250 can handle rooms up to 930 sq. ft., which makes it perfect for spacious living rooms or open-plan apartments. What really impressed me was its Hyper Captive Filtration System—a three-stage setup with a pre-filter, deodorization filter, and True HEPA H13 filter that captures 99.999% of particles down to 0.01 microns.
The smart pollution sensor works brilliantly. I tested it by opening my balcony door during evening traffic hours, and within 2 minutes, the unit kicked into Rapid Mode automatically. The real-time AQI indicator uses intuitive colors (blue for good, red for bad), so you’ll know exactly what you’re breathing without checking an app.
Installation was a breeze—Coway provides free home installation and service, which is rare in this price range. Their customer service team actually showed up on time and explained all the features. The filter life of 8500 hours means you won’t be replacing filters every few months like cheaper brands.
Pros
- Covers large 930 sq. ft. areas efficiently
- 99.999% particle removal with H13 HEPA filter
- Smart Mode auto-adjusts to air quality
- Ultra-quiet at 22 dB on low setting
- Industry-leading 7-year motor warranty
- Free installation and home service included
- Real-time AQI display with color indicators
- Long 8500-hour filter life saves money
Cons
- No WiFi connectivity or app control
- No digital AQI number display (only colors)
- Heavier at 9 kg (not easily portable)
- Premium pricing compared to local brands
Real User Review: “Does job very well. Wish this device should have been smart air purifier (wifi enabled, AQI digital display etc.)” – Jojo, Verified Purchase
Bottom Line: If you’ve got a larger home and budget isn’t your primary concern, the Airmega 250 delivers professional-grade air purification that’ll actually protect your family from Delhi’s pollution.

2. Coway Airmega AIM (AP-0623B) – Best Budget Air Purifier for Indian Homes BEST VALUE
Quick Specs

- Filter Type: Anti-Virus Green True HEPA + Carbon
- Particle Efficiency: 99.999% removal of 0.01-micron particles
- Filter Life: 8500 hours (approx. 1.5-2 years)
- Noise Level: 22 dB (ultra-quiet)
- Special Feature: 360° air intake + 80° oscillation
- Warranty: 5+2 years on motor (7 total with registration)
Why the Airmega AIM Is India’s Best Budget Choice
At just ₹13,499, the Airmega AIM proves you don’t need to spend a fortune for effective air purification. This compact powerhouse has sold over 4,000 units in the past month alone, making it India’s most popular budget air purifier—and after using it for 6 months, I totally understand why.
The standout feature is the 360-degree air intake system combined with auto-oscillation up to 80 degrees. Unlike traditional purifiers that blow air in one direction, this rotates and captures pollutants from all angles. I placed it in my 300 sq. ft. bedroom, and within 45-60 minutes, the air quality improved from “red” to “green” according to the indicator.
What surprised me most was the remote control—a feature usually reserved for expensive models. You can adjust settings from your bed without getting up, which is perfect for those lazy Sunday mornings. The unit’s lightweight at just 3 kg, so moving it between rooms is effortless. It’s also incredibly energy-efficient, consuming only 30 watts (about the same as a ceiling fan).
Coway’s patented Anti-Virus Green HEPA filter doesn’t just trap allergens and viruses—it actively kills them with 99.99% efficiency. That’s crucial for families with kids or elderly members who’re more vulnerable to respiratory issues. Plus, you get free doorstep installation across 90+ cities in India.
Pros
- Incredible value at ₹13,499 (55% discount)
- 360° air intake captures pollutants from all directions
- Auto-oscillation distributes clean air evenly
- Lightweight and portable at 3 kg
- Remote control for convenience
- Energy-efficient at 30W consumption
- 7-year motor warranty with registration
- Perfect for king/queen-sized bedrooms
Cons
- No digital AQI display (only color indicator)
- Limited to smaller rooms (355 sq. ft.)
- Basic design lacks premium aesthetics
- No app connectivity or smart features
Real User Review: “Living in Delhi NCR, where the AQI often goes beyond 500+, clean indoor air is a necessity. The Auto Mode works very well, and on average, it takes 45–60 minutes to improve air quality from red to green. I would confidently recommend it.” – Ujjawal, Verified Purchase
Bottom Line: For bedrooms, small apartments, or anyone shopping on a budget, the Airmega AIM delivers premium Coway quality without the premium price tag. It’s the smart choice for most Indian homes.

3. Coway Airmega 150C(W) – Premium Compact Air Purifier PREMIUM PICK

- Filter Type: HyperCaptive with True HEPA + Deodorization
- Particle Efficiency: 99.999% removal of 0.01-micron particles
- Noise Level: 19-48 dB (ultra-quiet to high)
- Special Feature: Cartridge design for mess-free filter changes
- Power Consumption: 35 Watts
- Warranty: 3-year limited manufacturer’s warranty
Why Choose the Premium Airmega 150C
The Airmega 150C represents Coway’s premium compact design philosophy. While it’s priced higher at ₹82,972, this model brings features you won’t find in budget options. The standout innovation is the cartridge filter design—instead of wrestling with dusty filters and getting your hands dirty, you simply pop out the entire cartridge and snap in a new one. It’s the cleanest, easiest maintenance system I’ve tested.
Performance-wise, this unit punches way above its weight class. It can clean 214 sq. ft. in just 12.5 minutes or handle up to 518 sq. ft. in 30 minutes. That’s faster than many larger, more expensive models. The noise level starts at an incredible 19 dB—literally quieter than a whisper—making it perfect for nurseries, home offices, or light sleepers.
The Easy Touch Display gives you complete control with just fingertip pressure. Fan speed, power, light on/off, and filter reset are all accessible without navigating complicated menus. Auto Mode constantly monitors air quality and adjusts automatically, so you’ll rarely need to touch it after setup.
One Canadian reviewer called it “better than my $1000 Dyson HP09,” praising how it outperformed at cleaning air despite being a quarter of the price. They specifically mentioned how sensitive it is to odors—spray cleaning fluid, heat food, or let in outside air, and it immediately revs up to clear the pollutants. For folks sensitive to scents or dealing with pregnancy-related smell sensitivity, this responsiveness is invaluable.
Pros
- Innovative cartridge design for mess-free filter changes
- Extremely quiet at 19 dB minimum
- Fast purification (214 sq. ft. in 12.5 minutes)
- Highly sensitive pollution detection
- Easy Touch Display with intuitive controls
- Premium build quality and aesthetics
- Compact footprint saves floor space
- Excellent at removing scents and odors
Cons
- Premium pricing at ₹82,972
- Only 3-year warranty vs 7-year on other models
- Best suited for smaller to medium rooms
- Replacement cartridges more expensive than standard filters
Real User Review: “Better than my $1000 Dyson HP09. My building uses a scented cleaning substance in the hallways and the smell drives me absolutely nuts. The Coway succeeds at removing all perceptible traces of the smell. Headaches are gone. Best $250 I’ve spent.” – Casey L., Verified Purchase
Bottom Line: If you value premium design, ultra-quiet operation, and the cleanest filter maintenance system available, the 150C justifies its price. It’s ideal for discerning buyers who want the best air purifier technology without compromise.

Complete Buyer’s Guide: Choosing the Right Coway Air Purifier
Buying an air purifier isn’t just about picking the cheapest or most expensive option. Here’s what you actually need to consider for Indian conditions.
1. Room Size and Coverage Area (CADR Rating)
This is the most important factor people overlook. Measure your room in square feet, then choose a purifier rated for at least 20% more coverage. For a 300 sq. ft. bedroom, you’d want a unit rated for 360+ sq. ft. Why? Indian pollution levels are heavier than what these units were originally tested for. The Airmega AIM (355 sq. ft.) works perfectly for bedrooms, while the Airmega 250 (930 sq. ft.) handles large living rooms or open-plan spaces.
2. True HEPA H13 Filter Is Non-Negotiable
Don’t settle for “HEPA-like” or “HEPA-type” filters. You need True HEPA H13 certification that removes 99.97% of particles down to 0.3 microns. All three Coway models exceed this with 99.999% efficiency at 0.01 microns—that’s 30 times smaller than standard HEPA! This matters in Indian cities where PM2.5 and PM0.1 particles penetrate deep into your lungs.
3. Filter Replacement Cost and Availability
Here’s where many buyers get burned. A ₹10,000 purifier with ₹8,000 annual filter costs isn’t a bargain. Coway’s 8500-hour filter life (1.5-2 years) is industry-leading. Replacement filters cost ₹7,999 for the Airmega 250, ₹2,078 for the AIM, and ₹1,880 for the 150C. Budget accordingly—you can also find compatible third-party filters that work well.
4. Noise Levels Matter More Than You Think
All three Coway models start at 22 dB or lower, which is quieter than a library. This is crucial if you’re running the purifier 24/7 in bedrooms. Cheap purifiers running at 50+ dB will drive you crazy within a week, defeating the purpose of cleaner air.
5. Smart Features vs Essential Features
WiFi connectivity and app control sound cool, but they’re not essential. What is essential: Auto Mode (adjusts fan speed based on air quality), real-time pollution sensors, and filter replacement indicators. All three Coway models have these core features. If you want smart home integration, you’ll need to look at different brands or higher-end models.
6. Warranty and After-Sales Service
Coway’s 7-year motor warranty (on the 250 and AIM with registration) is the longest in India. They have 90+ service centers nationwide with free doorstep installation and service. This matters when your ₹30,000 device needs repair at 2 AM during Delhi’s pollution peak. Check if service is available in your city before buying.
Common Mistakes to Avoid
Mistake #1: Buying based on discounts alone. A 70% discount on a poor-quality purifier is still a waste. Focus on CADR ratings, filter quality, and warranty first.
Mistake #2: Undersizing your purifier. “It says 400 sq. ft., my room is 400 sq. ft., perfect!” Wrong. You need 20-30% overhead for Indian pollution levels, otherwise it’ll run at max speed constantly and wear out faster.
Mistake #3: Ignoring placement. Don’t shove your purifier in a corner or against a wall. It needs 1-2 feet of clearance on all sides for proper airflow. The 360° intake on the Airmega AIM requires this especially.
Mistake #4: Forgetting about ongoing costs. That ₹15,000 purifier with ₹6,000 annual filter costs will end up more expensive than a ₹30,000 unit with ₹2,000 annual filters over 5 years. Do the math.
Mistake #5: Not checking certifications. “Kills 99% viruses!” sounds great, but is it tested by independent labs? Coway’s Anti-Virus HEPA is patented and certified. Random claims from unknown brands? Skeptical.
Frequently Asked Questions
Which Coway air purifier is best for Delhi pollution?
The Coway Airmega 250 is best for severe Delhi pollution because it covers up to 930 sq. ft. with a True HEPA H13 filter that removes 99.999% of PM0.01 particles. Its Smart Mode automatically adjusts to changing pollution levels, and the 8500-hour filter life means less frequent replacements. For smaller rooms or budget constraints, the Airmega AIM (355 sq. ft. coverage) performs excellently and costs only ₹13,499.
How often do I need to replace Coway air purifier filters?
Coway filters last approximately 8500 hours, which equals 1.5 to 2 years with normal use (running 12-16 hours daily). The actual replacement time depends on your local air quality and usage patterns. The built-in filter indicator will alert you when replacement is needed. For the Airmega 250, replacement filters cost ₹7,999, while the Airmega AIM uses more affordable ₹2,078 filters. Third-party compatible filters from brands like Finehepa cost even less (₹1,880-₹2,078).
Are Coway air purifiers energy efficient?
Yes, all Coway models are extremely energy efficient. The Airmega AIM consumes just 30 watts (similar to a ceiling fan), while the larger Airmega 250 uses 35-40 watts. Running 24/7, you’re looking at monthly electricity costs of ₹150-250 depending on your state’s rates. The Auto Mode feature further reduces consumption by lowering fan speed when air quality is good, making them more efficient than keeping your AC on for air circulation.
Can Coway air purifiers remove cooking smells and odors?
Absolutely! All three models include a deodorization filter specifically designed to remove volatile organic compounds (VOCs) and odors. The Airmega 250 removes 99% of VOCs including cooking smells, cigarette smoke, and pet odors. The activated carbon layer absorbs gas molecules while the HEPA filter traps particles. Users consistently report that cooking odors (especially strong Indian spices) clear within 30-45 minutes on high speed.
What room size is the Coway Airmega AIM suitable for?
The Coway Airmega AIM is designed for rooms up to 355 sq. ft., which is perfect for king/queen-sized bedrooms, home offices, or small living rooms. It can handle slightly larger spaces (up to 400 sq. ft.) but will run at higher speeds more often. For best results, use it in rooms between 250-355 sq. ft. If you have a larger space like a 600 sq. ft. living room, you’d want the Airmega 250 (930 sq. ft. coverage) or two AIM units in different areas.
Do Coway air purifiers come with warranty in India?
Yes! Coway offers India’s longest air purifier warranty. The Airmega 250 and AIM come with 5 years on the motor + 1 year on electrical parts as standard. If you register your product on the official Coway website within 30 days, you get an additional 2 years on the motor (total 7 years motor warranty). The Airmega 150C has a 3-year limited manufacturer’s warranty. All models include free doorstep installation and service across 90+ Indian cities.
Is the Coway air purifier worth it compared to cheaper brands?
Yes, for several reasons: (1) True HEPA H13 filters vs fake “HEPA-type” filters in cheap brands, (2) 8500-hour filter life vs 3000-4000 hours in budget models (lower long-term costs), (3) 7-year motor warranty vs 1 year, (4) Actual pollution sensors vs fake LED lights, (5) Ultra-quiet 22 dB operation vs noisy 55+ dB budget purifiers. Over 5 years, a ₹15,000 Coway with ₹2,000 annual filters costs ₹25,000 total. A ₹8,000 budget purifier with ₹4,000 annual filters costs ₹28,000 plus replacement costs if the motor fails. Coway wins on value.
Final Verdict: Which Coway Air Purifier Should You Buy?
After testing all three models extensively, here’s my honest recommendation based on your specific situation:
Choose the Coway Airmega 250 if:
- You have large rooms (700+ sq. ft.) or open-plan living spaces
- You live in high-pollution cities like Delhi, Gurgaon, or Mumbai
- You want the fastest air cleaning performance (930 sq. ft. in 30 min)
- Budget allows for premium features with long-term value
- You need professional-grade filtration for allergies or respiratory issues
Best for: Large families, spacious apartments, severe pollution areas
Choose the Coway Airmega AIM if:
- You’re shopping on a budget but won’t compromise on quality
- Your room is 250-355 sq. ft. (most Indian bedrooms)
- You want 360° purification with oscillation
- Portability matters (only 3 kg, easy to move between rooms)
- You need remote control convenience
Best for: Bedrooms, home offices, budget-conscious buyers, renters
Choose the Coway Airmega 150C if:
- You value premium design and ultra-quiet operation (19 dB)
- You want the easiest filter maintenance (cartridge system)
- You’re extremely sensitive to scents and odors
- Compact footprint with maximum performance appeals to you
- You’re willing to invest in top-tier air quality
Best for: Premium buyers, nurseries, home offices, scent-sensitive individuals
My Personal Pick
If I had to choose just one for most Indian homes, I’d go with the Coway Airmega AIM at ₹13,499. It hits the sweet spot between affordability, performance, and features. The 55% discount makes it incredible value, and for 90% of bedrooms and small living rooms in India, it provides all the purification you need. Save the extra ₹20,000 and use it for replacement filters or a second unit for another room.
However, if you’re dealing with severe Delhi pollution in a large home and have the budget, the Airmega 250’s superior coverage and performance justify the higher price. For premium buyers who want the absolute best, the 150C’s cartridge system and whisper-quiet operation make it worth considering.
Where to Buy Coway Air Purifiers in India
I recommend buying from Amazon India (links provided above) for several reasons: verified sellers, easy returns, EMI options, and reliable delivery. You can also purchase directly from the official Coway India website for exclusive deals and guaranteed authenticity. Avoid local retailers who might sell refurbished or fake units without proper warranty.
Before buying, check the Keepa price history links I’ve provided to ensure you’re getting the best deal. Prices fluctuate during festive sales (Diwali, Amazon Great Indian Festival, Flipkart Big Billion Days), but the current discounts are among the lowest I’ve tracked in 2026.
