air filer

Most listings report a typical replacement interval of about 12 months, while at least one model specifies a 9‑month interval. Check your specific model's documentation and consider factors such as runtime, indoor air quality, and filter type, which can shorten or extend filter life.

Common filter types across the results are HEPA (HEPA‑grade) filters, activated carbon (carbon) filters, and prefilters. HEPA filters are used for particle capture, activated carbon targets odors and some VOCs, and prefilters trap larger debris; many units combine two or more of these layers.
