Coway Air Purifiers: Review, Models & Prices (2026)

Coway's service network is rated limited in our assessment. That means coverage in India is genuinely limited. Before buying, confirm that a technician serves your area and that replacement filters can be delivered to your pin code — an appliance you cannot service or re-filter is a poor purchase at any price.

Before ordering any purifier, call the brand's customer care, give them your pin code and ask two questions: is there a technician covering this area, and how many days does a filter-change request typically take? Then ask for the AMC price in writing. That five-minute call prevents most of the regret in this category.

• Raise service requests through Coway's official website only — https://coway.co.in/support. Third parties advertising "authorised Cowayservice" frequently have no brand relationship, charge more and fit non-genuine parts.
• Always insist on a ticket or complaint reference number, and note the promised response window.
• Ask the technician to record input and output PM2.5 readings on the service slip at every visit. It is your evidence base and it makes vague diagnoses much harder to sustain.
