Through a Delhi NCR monsoon the air routinely sits above 80% relative humidity, and that single number is behind most of what goes wrong indoors in July and August. Above 60% RH, mould takes hold on wardrobe backs and bathroom-adjacent walls, dust mites multiply in mattresses and sofa fabric, and the room feels sticky no matter how low you set the AC — because the air conditioner is fighting temperature while the real problem is moisture. At 30°C and 80% RH this Sharp removes 27 litres of water from the air every day. The 4.6 L tank runs a full day, and a continuous drainage connector lets you set it up permanently against a drain and never empty a tank at all.
Plasmacluster Ion Technology — Sharp’s signature, and one of the most independently verified
A filter can only clean the air that reaches it. Plasmacluster works on the air still out in the room. The unit generates positive and negative ions — the same ions that occur naturally in forest air and near waterfalls — and releases them into the space, where they attach to airborne bacteria, viruses, mould spores and allergens. That attachment triggers a hydroxyl radical reaction on the surface of the pathogen, breaking down its protein structure and deactivating it in the air rather than merely trapping it. It has been certified by 35+ independent research institutions worldwide, including IIT Delhi and the British Allergy Foundation — a depth of external validation that is rare in this category. During a Delhi monsoon it is the Mold Control mode that earns its keep, aiming Plasmacluster directly at the humidity-driven spore load of July to September.
Triple-layer filtration with a 5-year filter life — the running cost most buyers forget to check
Most purifiers ask you to replace filters every year or two, and across a decade that quietly costs more than the machine. Sharp rates both the HEPA and the activated carbon layers here for up to 5 years, and the pre-filter is washable and reusable — so the long-term cost of clean air in your home stays low. That matters in Delhi, where the purifier is not a seasonal gadget: it runs against monsoon mould through the summer and against winter PM2.5 from November onwards.
🧫 What each filtration layer actually removes
Washable Pre-Filter
Catches large dust, hair and lint — rinse it and reuse it, protecting the finer filters behind
Activated Carbon
Adsorbs gaseous pollutants — VOCs from paint and furniture, cooking smells, traffic exhaust
True HEPA
Captures 99.97% of particles at 0.3 micron — PM2.5, pollen, pet dander, smoke, mite debris
Plasmacluster
Works out in the room air on bacteria, viruses, mould spores and allergens as they circulate
🎛️ Six modes, one dial
Auto
Sets itself from the PM2.5, humidity and odour sensors
Dehumidify
Hold the room at 40, 50, 60, 70 or 80% RH — your choice
Mold Control
Aims Plasmacluster ions squarely at monsoon mould risk
Laundry
Dries clothes indoors faster and keeps the air clean doing it
Deodorizing
Active odour removal — cooking, pets, smoke, stale air
Sleep
Near-silent running with the indicator lights dimmed down
🛰️ Sensors and controls on board
The full-tank sensor is the practical one — the unit stops and tells you before the 4.6 L tank can overflow, so you can leave it running all day with the flat locked.
Live PM2.5 alongside room temperature and humidity on the panel. Through a Delhi November when the outdoor AQI is in the 300s, watching the indoor number fall is the proof that the machine is doing its job.
Two independently controlled louvers give a combined 180° of throw, so purified and dried air actually reaches the far corners of a large drawing room rather than circulating in front of the unit.
The panel indicators brighten with the room and dim themselves in the dark, so nothing glows at you across the bedroom. With Sleep Mode running quietly alongside, the unit stays out of the way all night.
Have it clean and dry the flat while you are at work and switch off before you get back, or start two hours before you wake. Scheduled running keeps the electricity bill sensible without giving up air quality.
