Research-backed recommendation
This comparison comes down to what you value most.
Choose the Coway Airmega 400 if: You want maximum air purification per dollar. The 3x higher CADR and 2x coverage mean the Coway cleans more air, faster, across larger spaces. The 5-year warranty provides long-term protection. This is the rational choice.
Choose the Dyson TP07 if: Design, dual functionality, and smart home integration matter as much as filtration. The bladeless tower looks stunning, works as a cooling fan, and integrates seamlessly with smart home platforms. The sealed system ensures genuine particle capture. This is the lifestyle choice.
For most families, the Coway delivers better pure-filtration value. But the Dyson serves a real market of design-conscious, smart-home-integrated buyers who want their purifier to do double duty.

Both units cost $549 MSRP. The Coway occasionally drops to $449 on sale; the Dyson rarely discounts. Over 5 years with filters, the Coway costs approximately $850 vs $870 for the Dyson. Essentially equivalent total cost for very different products.
Buy the Coway if raw filtration power matters most. Buy the Dyson if design, dual functionality, and smart features justify paying the same price for less CADR.
