From late October, Delhi's air stops being a background worry and becomes the thing you plan your day around. Most purifiers are sized for one bedroom, which means the drawing room, the passage and the kitchen keep feeding polluted air back in the moment a door opens. The Big+Quiet BP02 is engineered for whole-room purification across 100 square metres — 1,076 square feet, the same figure stated two ways — so a large drawing room, an open-plan living-dining, or a floor of a Delhi NCR office is covered by one machine rather than three. Its airflow was developed using Computational Fluid Dynamics modelling, and it holds that coverage even when the machine sits in a corner, out of the way.
Cone aerodynamics — clean air that actually reaches the far wall
Purification only counts where the clean air lands. Dyson's cone aerodynamics deliver powerful, long-range projection with a horizontal throw of up to 10 metres, circulating the room and driving distant pollutants back through the sealed filters rather than leaving them hanging at the other end of the hall. That is what turns a filter rating into whole-room performance, and it is the difference between a purifier that cleans the air around itself and one that cleans the room you are sitting in.
Fully sealed to HEPA H13 — what goes in, stays in
Two phases of purification sit inside a fully-sealed machine, so pollutants are trapped inside and removed from the air you breathe instead of leaking back out around the filter edges. The HEPA H13 grade filter captures 99.95% of ultrafine particles as small as 0.1 microns — tested to EN1822 and ISO29364 using DEHS oil particles in ASTM F3150 chambers — which is the standard that matters through a Delhi winter, when the fine fraction is exactly what gets past cheaper machines. When the filter has done its work, a hygienic replacement mechanism lets you dispose of it in one click, without handling what it has collected.
🎛️ Four ways to run it
Auto Mode
Senses, captures and reports on pollutants in real time, adjusting purification by itself
Breeze Mode
Mimics the feeling of refreshing moving air indoors
Max Mode
Full output — 99.95% particle filtration efficiency measured in Max Mode
0° / 25° / 50°
Set the airflow angle to aim clean air where you actually sit
🧫 Two phases of purification, fully sealed
HEPA H13 Filter
99.95% of ultrafine particles as small as 0.1 microns — dust, pollen, pet dander, mould spores and airborne bacteria
Activated Carbon
Removes odours and gases — VOCs, smoke, pet smells and kitchen odours
Fully Sealed Machine
Both phases sit inside a sealed body so trapped pollutants stay trapped
One-Click Replacement
A hygienic mechanism disposes of the HEPA filter in a single click
📡 Sensing, display and control
The sensor suite detects pollutants across the whole room and a Dyson algorithm cross-checks the data every second, analysing the air at a molecular level and reacting automatically — with live results on the LCD screen and in the app. The built-in CO₂ sensor is the one Delhi flats rarely have: with windows shut all winter, it tells you when carbon dioxide passes 1500 ppm and it is time to ventilate.
The activated carbon stage has been through gas filtration testing for formaldehyde, benzene, acetic acid, acetaldehyde, ammonia (JEM 1467) and nitrogen dioxide (DTM-003282), with third-party testing to GB/T 18801-2022 for formaldehyde cumulative clean mass performance. That covers the traffic gases and the new-furniture off-gassing that a particle filter alone does nothing about.
An acoustically engineered motor bucket records just 56 dBA of sound power at full speed, with no compromise on performance. That is the point of the "Big+Quiet" name: you can run it hard through a bad AQI night in the bedroom and still sleep, instead of turning it down and losing the purification exactly when you need it.
The app gives you autonomy over your air quality — see which particles have been captured, set schedules, browse reports and adjust fan speed from wherever you are. It runs on iOS 10+ or Android 5+ over Wi-Fi and Bluetooth 4.0, and the machine also connects to compatible smart home voice services for hands-free control.
Concealed wheels designed for hard surfaces let you manoeuvre the machine from the drawing room to the bedroom easily, and stay completely hidden from view. At 830 mm tall in a White/Satin Silver finish, it reads as a piece of furniture rather than an appliance parked in the corner.
