Model-to-filter directory
Similar purifier names can use different filters.
Check the label on the purifier itself. A marketplace title or visual resemblance is not enough—especially when a model adds an “S,” “i,” “Max,” or warehouse-club suffix.

Levoit filter guide
Three official product-page starting points; current price, interval, and pre-filter details remain unverified because the site rate-limited access.
Open Levoit guide →Coway filter guide
Official product-page starting points for AP-1512HH, Airmega 240, and Airmega 250 filter sets.
Open Coway guide →Winix filter guide
Official Filter H and Filter S starting points with unresolved detail fields shown rather than guessed.
Open Winix guide →Cost boundary
A filter interval is guidance, not a guaranteed lifespan.
Smoke, dust, pets, cooking particles, runtime, fan speed, and pre-filter maintenance can change replacement timing. Use the manufacturer’s indicator and instructions, then calculate a range rather than assuming the longest interval.
