25 mm
8500 hrswhere the money is
On an air purifier the machine is a one-time cost and the filters are the recurring one, so filter life is the specification that decides what you actually spend over five years. This unit's HEPA is 25 mm thick and rated for 8500 hours — thickness matters because a deeper filter holds more particulate before airflow drops, which is what extends the interval between replacements rather than just delaying the alert. Coway describes this as substantially longer than an ordinary filter, and it is the honest reason to look at this model over a cheaper one. Run the arithmetic before buying: ask us the filter price, divide by the life you'll realistically get, and compare that against the machine you're weighing it against. A cheaper purifier with thin, frequently-replaced filters costs more by year three.
Read the warranty structure carefully — it is not seven years of everything
Supplier material headlines this as a "7-year total warranty", and we would rather explain exactly what that adds up to than let you assume. It is 5 years on the motor, 1 year on electrical parts, and 2 further years on the motor if you register the product with Coway. So the long cover applies to the motor — the electrical and electronic parts carry one year. That is a perfectly reasonable structure, and five-to-seven years on a motor is a real commitment, but it is a different thing from seven years of comprehensive cover, and a customer who discovers the difference in year two is entitled to be annoyed. Register for the extended motor cover on the day it's installed, not later. Filters are consumables and are never covered by any warranty. Ask us to confirm the exact terms in writing before you buy.
Focus circulation — the feature that actually distinguishes this model
Most purifiers do one thing: draw air in and push it out in a fixed pattern. This one offers two. Normal circulation works the whole room; Focus circulation concentrates the airflow at a specific spot — the sofa where the family sits, the side of the bed, a desk, or the corner nearest the kitchen where cooking smoke drifts in. It matters because a purifier's rated coverage is measured in an open room, and real rooms have furniture, corners and doorways that break up circulation. Being able to aim the output at where people actually sit gets you cleaner air where it counts rather than an evenly mediocre average. Dual-direction airflow — forward or upward — does the same job vertically. Use Focus after cooking and Normal the rest of the time.
🌫️ The three filter stages, and what each one is for
1 · PRE-FILTER
Catches hair, lint, dander and coarse dust before anything finer sees them. Keeping it clean is what protects the expensive filter behind.
2 · URETHANE CARBON
Smells and VOC fumes — cooking, smoke, oil mist, paint, new furniture. The stage whose effect you notice first.
3 · GREEN TRUE HEPA
The fine-particulate stage, and at 25 mm the thickest part of the system. This is what deals with PM2.5 and fine dust.
🎯 Right for
575 sq ft is a rated figure for an open space at a standard ceiling height. A real room with furniture, a high ceiling or an open doorway will need more purifier than the number suggests — tell us your dimensions and we'll say honestly whether this or a larger unit fits.
Green, yellow, red and purple — one step finer than the usual three-colour scale, so you can see the difference between "bad" and "very bad".
Reads the room and sets fan speed itself. The setting to leave it on — it runs quiet when the air is clean and harder when it isn't.
Dims the lights and drops the noise for sleep. A purifier that glows and hums in a bedroom is a purifier that gets switched off.
Modest even at full speed — which matters on an appliance designed to run continuously through a pollution season.

Warranty as per Coway India's terms and conditions — 5 years on the motor, 1 year on electrical parts, and 2 additional years on the motor subject to product registration on Coway's official channel within the period they specify. This is not seven years of comprehensive cover; the extended term applies to the motor. The scope of cover, exclusions, parts and labour, registration requirements and the service process are subject to brand policy and the final invoice or warranty card, and should be confirmed in writing before purchase. Filters are consumables and are not covered by any warranty. Installation, demonstration and doorstep service, where offered, are arranged through Coway India and 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, asthma, 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 its filters are not designed to capture. Filtration performance, coverage, clean-air delivery, particle capture, odour reduction, AQI sensor readings, noise levels, 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 and orientation, circulation mode selected, door and window opening, outdoor air quality, cooking and smoking activity, occupancy, fan speed, sensor cleanliness, filter condition and maintenance; the stated coverage is a rated figure and is not a guarantee of performance in any particular room. The stated filter life of up to 8500 hours is an estimate under typical conditions and will be shorter in high-pollution or high-dust environments; replacement filters are chargeable separately. Supplier material for this model contains inconsistencies in the stated filter grade, the published dimensions, and the description of an additional purification stage; these are flagged in the specification table above and must be confirmed with us before ordering. Any ionisation function should be used strictly in accordance with the manufacturer's manual.
