Vivosun 4 Inch Prefilter for 4" Carbon Filter, White, 2 Pack

Description

The VIVOSUN 4 Inch Prefilter for 4" Carbon Filter is a replacement filter sleeve designed to help growers protect carbon filters from dust, debris, and larger airborne particles inside smaller grow tents and hydroponic setups. With its 4-inch compatibility and white fabric design, it supports cleaner and more consistent plant-growing conditions.

Built for carbon filter protection, the prefilter adds an outer layer that helps reduce buildup on the main filter surface during regular ventilation use. This helps keep airflow cleaner while supporting better odor-control performance and easier maintenance throughout indoor growing cycles.

Designed for indoor cultivation and grow tent air management, this 2-pack provides a simple replacement solution for compact filtration setups. Its soft sleeve design, easy installation, and carbon filter compatibility make it useful for growers who want cleaner airflow, longer filter support, and healthier plant development.
