Coway Airmega 150 vs Philips AC1715 (2026): Which Air Purifier Is Worth ₹15,000?

Coway Airmega 150 vs Philips AC1715 is the comparison most people end up making once they have set a budget of about ₹15,000 and want a name they trust. The two machines cost within ₹1,009 of each other, both use H13-grade True HEPA filters, both are meant for bedrooms and living rooms, and both come from brands with a long air-care history. They are, though, built around different ideas. The Coway is a plain, sturdy purifier with a very well-rated record and cheap filters. The Philips is a compact, quiet smart purifier with an app, a sensor that reads allergens and a higher running cost.

We have not tested either unit ourselves. This comparison uses the Amazon.in listings (prices and ratings checked on 13 Nov 2026), the manufacturers' published specs, and our own arithmetic on filter and electricity costs. Where the sources disagree or say nothing, we say so.

The short answer

• Choose the Coway Airmega 150 if you want the safest bet. It has the better buyer record (4.7 out of 5 from 6,824 ratings), a filter that costs about ₹1,000 to ₹1,700 less per change and lasts longer, and a 7-year motor warranty. You give up Wi-Fi and a number on the display.
• Choose the Philips AC1715 if you want to control the purifier from your phone, check allergen levels, or put it in a bedroom where every decibel counts. You pay more for the filter each year.
• If you do not need the app, the cheaper non-smart Philips AC1711 is the Philips worth looking at, not the AC1715.

Airflow and room size: almost a tie

The two machines move almost the same amount of air. Coway's published figure for this model is about 303 m³/h, and Philips states 300 m³/h. The Amazon.in listing for the Coway talks about coverage (355 sq ft) rather than CADR, which is why many buyers never see the number.

CADR is the volume of smoke-sized particles a purifier clears per hour, and it is the figure that decides whether a machine keeps up with a room. A simple way to use it: divide the CADR by 5 to get the room volume it can turn over five times an hour, the rate most people want in a polluted city. 300 divided by 5 is 60 cubic metres, which is a room of roughly 210 sq ft with a 10 ft ceiling.

That is why we do not accept the 355 and 380 sq ft claims at face value. Both are best-case figures with fewer air changes an hour. In our view the realistic ranges are:

• Heavy winter smog (Delhi NCR, Lucknow, Patna): up to about 200 to 250 sq ft.
• Average city air, or if you only want a few air changes an hour: up to about 300 sq ft.

A typical 12 ft by 14 ft bedroom (168 sq ft) is comfortable for either. A 400 sq ft hall is not, and for that you want more airflow than either offers. Our guide to CADR in air purifiers shows the sums in more detail.

Noise: the Philips has the quieter floor

Philips publishes 15 dB in sleep mode and 50 dB on the top setting. The Coway listing gives 22 dB at the lowest speed, and its higher speeds are audible. The gap between 15 and 22 dB is small in absolute terms, since both are quieter than a whisper in a still room. If the person sleeping is easily woken, or the machine sits within an arm's length of the bed, the Philips is the safer pick. For a living room, where a purifier runs on auto during the day, you are unlikely to care.

One thing worth knowing about the Coway: its auto mode raises and lowers the fan by itself based on the colour light, so it may speed up when you cook or when a neighbour is burning something. Some owners like that, and others find it disruptive in a bedroom. You can set it manually, but then you lose the main point of the mode.

Filters and running cost: where the Coway pulls ahead

The sticker price is only the start. These are the numbers that decide which of the two is cheaper in year three.

The sums assume the Coway filter lasts its rated 8,500 hours, which is about 700 days at 12 hours a day, so one change in three years. If you run it around the clock, 8,500 hours is just under a year, and the Coway total becomes 14,990 plus two filters, about ₹21,588. The Philips figure assumes a yearly change as Philips recommends. In heavy smog you may need to change either earlier.

Electricity is a minor cost for both. At 12 hours a day and ₹8 a unit, the Coway at 35 W comes to roughly ₹100 a month and the Philips (27 W at maximum) to under ₹80. Both numbers are upper bounds, since a purifier on auto rarely runs flat out.

A word on cheaper "compatible" filters. Searching Amazon.in turns up non-genuine sets for both models at ₹1,500 to ₹3,500. Some are fine, but their buyer ratings are usually thin or mixed (a few hundred reviews at around 3.8 to 3.9 for one popular Coway-compatible set, a dozen reviews at 3.4 for one Philips-compatible filter). A badly fitted filter lets air slip past the HEPA layer, so we would stay with genuine filters. Our guide to the Philips FY1700 filter goes into the Philips side.

Smart features: do you actually need them?

This is the real dividing line. The Philips AC1715 connects to the Air+ app, so you can switch it on before you get home, set schedules, see live air quality and use Alexa or Google. Its AeraSense sensor reports PM2.5 and an allergen index. Both the app and the sensor need a 2.4 GHz Wi-Fi network; a router that broadcasts only 5 GHz gives people setup trouble.

The Coway has none of that. You get a four-colour light showing the air quality, an auto mode and a filter replacement indicator. For many households this is enough, because a purifier does its job whether or not you can see a number on your phone. If you have a phone full of smart-home gadgets and want to log air quality over the winter, the Philips is the better fit. If you want to plug it in and forget it, the Coway is.

What buyers say, and how far to trust it

The Coway's rating (4.7 from 6,824) is the strongest in this price band and rests on a large number of buyers. The Philips AC1715 has 4.2 from 318 ratings, a much smaller base, so its score moves more with a handful of bad reviews. That does not mean the Philips is a poor machine. Philips has been making air purifiers in India for years and its service network is well known. It just means we have less evidence about the AC1715 specifically.

Warranty and service

Philips offers 2 years on the AC1715. Coway lists 7 years on the motor and 1 year on electrical parts for the Airmega 150. In practice the motor is the part that costs the most to replace, so Coway's longer cover is worth having, but it only matters if you can get the unit serviced. Before you buy, check that the seller is authorised and that the brand has a service centre or technician arrangement in your city.

Who should buy which

Buy the Coway Airmega 150 if:

• You want the best-reviewed purifier near ₹15,000 and the lowest running cost.
• The room is a bedroom or living room up to about 250 sq ft.
• You are happy without an app.

Buy the Philips AC1715 if:

• You want app control, scheduling and allergen readings.
• It will sit within a metre of a bed and you want the quietest sleep mode.
• You prefer a compact, lighter machine you can move around (3.8 kg against 5.5 kg).

Buy neither if your room is bigger than about 300 sq ft or you live somewhere with severe winter smog and need a lot of airflow. The Qubo Q600 and the Cuckoo Respure DLX move about 430 to 450 m³/h for similar money.
