Filter Box

Clean air isn’t something you think about until it’s missing. The KCVENTS Filter Box quietly makes sure you never have to.

Available in 4, 6, 8, and 10‑inch sizes, it fits neatly into almost any ventilation or HVAC system, keeping air fresh and free from the dust, smoke, and fine particles that slowly build up indoors. Whether it’s a home, office, workshop, or grow tent, the Filter Box helps the space breathe easier.

Inside, each unit holds a high‑quality MERV 10 or MERV 13 filter, capable of capturing particles as small as 0.3 microns. The filter media is made from durable, heat‑resistant cotton, giving you effective, long‑term filtration without frequent replacements.

It slides into place easily — compact, lightweight, and surprisingly simple to add to an existing ventilation setup. Installation takes minutes, and the difference in air clarity starts almost immediately.

Built with the same careful engineering found in KCVENTS’ professional‑grade ventilation systems, this filter box keeps airflow steady and resistance low, even after months of continuous use.

Quiet, reliable, and maintenance‑friendly, the KCVENTS Filter Box isn’t just another part of the system — it’s the reason the air feels cleaner.
