Coway Airmega AP-1512HH Mighty vs Levoit Core 400S
Which should you buy? Our verdict on both, pulled from our full The Best Mid-Range HEPA Air Purifiers for Allergies comparison.
For most allergy sufferers the Coway Mighty remains the smart-money buy: proven allergen removal, the cheapest OEM filters, and a decade as the go-to top pick. Pay up for the Levoit Core 400S if you want app control, real-time PM2.5 data, and scheduling. The Winix 5500-2 is an excellent performer and the value play if you can still find it - but its US/Canada discontinuation makes it a conditional pick.

Levoit Core 400S

- Quiet on low speeds (22 dB on the 400S-P's lowest setting)
- No ozone-producing ionizer
- Higher long-term filter cost than the Coway's
- Levoit has replaced it with the Core 400S-P, so the original 400S is sell-through stock
- App/account requirement is a mild annoyance for a simple appliance
