7 + 2
yearswhat it signals
Seven years of comprehensive cover on an air purifier is unusual, and it's the specification worth leading with. Most purifiers at any price carry one or two years. A brand offering seven is making a statement about expected service life — manufacturers price warranty against expected failure rates, and nobody offers seven years on something they expect to be dead in four. The extra two years on the motor is worth claiming, because the motor is the part that actually wears in a machine that may run for months on end — but it requires registering the product with Coway, and there is normally a window after purchase in which to do it. Do it on installation day rather than trying to remember in year three. Ask us and we'll walk you through the registration when the unit is delivered.
Filters are the real running cost — here's the honest arithmetic
The thing nobody tells you when selling an air purifier is that the machine is a one-time cost and the filters are a recurring one. This unit's filter life is rated at about 8500 hours, which Coway puts at roughly one and a half to two years of typical use. But "typical" is doing a lot of work in that sentence: run it around the clock through a Delhi November, in a home with cooking smoke and street dust, and the filters load up faster. Ask us the filter price before you buy, not after — it is the only honest way to compare two purifiers, and a cheaper machine with expensive filters can cost more across five years. The pre-filter is washable and reusable: rinsing it under a tap once a month and letting it dry fully is what stops coarse dust loading the expensive HEPA behind it.
What "930 sq ft" actually means — and how to place it
Coverage figures on purifiers are rated under test conditions in an open space with a standard ceiling height, so treat the number as a guide rather than a promise. A purifier only cleans air it can circulate — a 930 sq ft rating does not stretch down a corridor into two bedrooms, and a machine pushed into a corner behind a sofa will fall well short of its rating. Give it clearance to draw air in and push it out, keep it away from curtains and walls, and put it in the room you actually spend time in rather than the largest room in the house. Close the door and the windows while it runs — a purifier competing with an open window in Delhi is losing. Tell us your room dimensions and ceiling height and we'll say honestly whether this size is right.
🌫️ The three filter stages, and what each one is for
1 · PRE-FILTER
Catches hair, lint, dander and coarse dust before they reach anything finer. Washable and reusable — cleaning it monthly protects the HEPA behind.
2 · DEODORISATION
Activated carbon for smells and VOC fumes — cooking, smoke, paint, new furniture. The stage whose effect you notice first.
3 · TRUE HEPA H13
The fine-particulate stage, rated H13 — a higher grade than the H11 and H12 filters common at this price. This is what deals with PM2.5.
🎯 Right for
One purifier cleans one room. If you want clean air in the bedroom and the living room, that's two machines — a large unit in a hallway does not do the job of two smaller ones in the rooms you use.
The sensor reads the room and sets fan speed itself — quiet when the air is clean, harder when it isn't. The setting to leave it on.
Maximum output for a bad AQI day, after frying, or during post-renovation dust. For when you can see or smell the problem.
Senses darkness, drops to the quietest speed and turns the AQI light off — because a glowing indicator in a bedroom defeats the point.
Green, yellow, red. Its real value is teaching a household what actually dirties the air — frying, incense, an open window.

Warranty as per Coway India's terms and conditions — 7 years comprehensive on the product, with an additional 2 years on the motor subject to product registration on Coway's official channel within the period they specify; the scope of cover, exclusions, consumable and filter exclusions, registration requirements and the service process are subject to brand policy and the final invoice or warranty card. Filters are consumables and are not covered by the product warranty. Installation and demonstration, where offered, are arranged through Coway India and are subject to their availability and terms. This appliance is an air purifier intended to reduce airborne particulate matter and odours within an enclosed room. It is not a medical device and makes no medical claim: it does not prevent, diagnose, treat or cure any disease, allergy, infection or medical condition, and it is not a substitute for medical advice, ventilation, extraction over cooking appliances, or remediation of damp or mould. It does not remove gases or vapours that its filters are not designed to capture. Filtration performance, coverage, clean-air delivery, particle capture, odour reduction, AQI sensor readings, noise level, power consumption and filter life are manufacturer specifications measured under defined laboratory test conditions and vary significantly in real use with room size, layout, ceiling height, furniture and obstructions, appliance placement, door and window opening, outdoor air quality, cooking and smoking activity, occupancy, fan speed selected, filter condition and maintenance; the stated coverage is a rated figure at a standard ceiling height and is not a guarantee of performance in any particular room. The stated filter life of approximately 8500 hours is an estimate under typical conditions and will be shorter where pollution levels are high or the appliance runs continuously at high speed; filters must be cleaned and replaced as indicated by the appliance and the user manual, and replacement filters are chargeable separately. The activated carbon deodorisation filter may require replacement more frequently than the HEPA filter in kitchens or high-odour environments.
