How it works

As air passes through the filter, particles such as dust and pet dander encounter polarized media that encourages clustering. These clusters become easier to capture within the fiberglass pad, while the activated carbon center helps address odors and chemical traces. The carbon layer sits on a non-woven polyester base, with a frame-friendly design that supports consistent airflow and reliable changes.

Care, timing, and notes
