Coway Airmega AP-1512HHS vs Levoit Core 400S-P

Levoit Core 400S-P, thanks to an AHAM Verifide 231 CFM smoke CADR, Energy Star certification at 38 W, Home Assistant support and a lower price. Coway Airmega AP-1512HHS answers with a 3 year warranty, a washable reusable pre-filter and an Eco Mode that switches the fan off when the air is clean.

Levoit Core 400S-P is AHAM Verifide at 231 CFM smoke CADR for 358 sq ft, tested in a standard chamber. Coway Airmega AP-1512HHS is not AHAM Verifide: its 210 CFM and 788 sq ft figures come from Coway's own testing at a lower air change rate, so they cannot be compared directly.

Coway Airmega AP-1512HHS uses True HEPA and activated carbon behind a washable reusable pre-filter, with an optional ionizer stage, and rates the filters at about a year. Levoit Core 400S-P uses a sealed 3-in-1 H13 True HEPA cartridge rated at roughly 8 months, whose pre-filter layer is vacuumed rather than washed.

Levoit Core 400S-P, at 38 W with Energy Star certification, against 80 W for Coway Airmega AP-1512HHS, which is not Energy Star certified. The Coway's Eco Mode does cut consumption in clean air by stopping the fan entirely, which the Levoit does not do.

Levoit Core 400S-P, which works with Alexa and Google Home through VeSync and is supported by Home Assistant's VeSync integration. Coway Airmega AP-1512HHS covers Alexa and Google Home through IoCare with no Home Assistant integration. Neither supports Apple HomeKit or Matter.

Buyers who value the 3 year warranty, a genuinely washable pre-filter that reduces long-term filter costs, and an Eco Mode that idles the fan in clean air, in a compact body suited to bedrooms. For certified airflow, lower power draw and Home Assistant control, Levoit Core 400S-P is the better fit.
