The 90-Day Owner Regret Check

Documented ergonomic quirks, hardware annoyances, and maintenance realities reported by real owners.

Post-Purchase Truths

Coway: What to watch for

Hardware Quirk
Ionizer ("Vital Ion") produces negligible ozone and should be disabled.
Many asthma and allergy sufferers immediately toggle the optional ionizer off to ensure completely emission-free mechanical HEPA filtration.

Levoit: What to watch for

Hardware Quirk
No true HEPA H13 rating on recent replacement filters.
Due to US regulatory naming updates, Levoit adjusted terminology from "True HEPA" to "HEPASmart" on several retail filter packs.
Maintenance
Filter check light does not measure real dirt; it operates on a fixed timer.
The filter replacement alert triggers every 6 months regardless of whether your room was smoky or pristine, requiring manual reset.
