Philips AC4221/61 Air Purifier — Double-Fan 4-Layer HEPA Purifier with Wi-Fi & Alexa

Philips AC4221/61 price: ₹26,500 for our most powerful air purifier — part of the PureProtect Pro 4200 Series, engineered with a double-fan design for up to 1.5x more power than similarly-sized purifiers. With a CADR of 600 m³/h and rated coverage up to 72 m² (700 sq ft), it purifies a standard 20 m² room in under 5 minutes, backed by a 2-Year Warranty.

Who This Is Built For

Before you check the Philips AC4221/61 price against your budget, it’s worth confirming the unit actually matches your room — a purifier that’s the wrong size for the space wastes both its CADR and your money.

Fast Purification of Rooms Up to 72 m²

With a CADR of 600 m³/h, the AC4221/61 purifies a standard room (18 ft × 12 ft, 8 ft ceiling) in roughly 5 minutes and effectively covers spaces up to 72 m² (700 sq ft) — coverage that makes the Philips AC4221/61 price easy to justify if you’re clearing air across a full living room rather than a single small space.

SilentWings Technology — As Quiet as 15dB

SilentWings technology delivers up to 50% less noise, bringing Sleep mode down to as low as 15dB(A) — quiet enough for bedrooms and nurseries — while maximum power tops out at 51.5dB(A) for rapid air refresh when you need it.

4-Layer Filtration, Explained

Air passes through four distinct stages: a Pre-Filter captures larger particles like dust, lint, and hair; the HEPA NanoProtect filter captures 99.97% of ultra-fine particles as small as 0.003 microns; and a double Activated Carbon layer traps odors and removes gaseous pollutants including smog and harmful gases. It’s this 4-layer system that anchors the Philips AC4221/61 price to genuine filtration performance rather than marketing alone.

*Per Philips’ product specifications — captures particles as small as 0.003 microns, smaller than the smallest known virus.

Removes Allergens, Dust & Airborne Microorganisms

The 4-layer filtration system helps capture pollen, dust, pet dander, smoke particles, bacteria, and certain viruses — supporting cleaner, more breathable air for allergy-prone households and everyday use alike.

Traps Smells and Gas Pollutants

The double Active Carbon layer captures odors from cooking, smoke, and household waste, and removes VOCs and other gaseous pollutants that hurt indoor air quality.

Wi-Fi, Alexa & Google Assistant via the Philips Air+ App

Pair the AC4221/61 with the Philips Air+ app for remote monitoring, control, scheduling, and voice commands through Amazon Alexa or Google Assistant — hands-free from anywhere in the room. Smart features like these are part of why the Philips AC4221/61 price sits above entry-level purifiers in our range.

Real-Time AQI Display with Ambient Ring Light

Built-in PM2.5 and gas sensors monitor indoor pollution continuously, with a soft ambient AQI ring light visually indicating current air quality at a glance — no need to open the app every time you want a status check.

AeraSense Technology — Real-Time Air Quality Sensing

AeraSense technology continuously scans the air to detect pollutants and gases, reporting air quality in real time on the display or in the app. In Auto mode, the AC4221/61 intelligently adjusts fan speed to match current air conditions without manual intervention.

Energy Efficient by Design

Running at just 54W maximum, the AC4221/61 delivers large-room, double-fan purification without a large power draw — an easy addition to your home’s daily energy footprint.
