Who This Is For
- You are adding a pre-filter because dust and lint in your room are clogging your carbon bed and killing its lifespan
- You are switching to these reusable sleeves because the thin stock wraps keep ripping during your cleaning routine
What We Found
- The 1.8mm cotton is thicker than most stock sleeves, so it actually traps the fine dust that usually slips through.
- We suggest using the two-pack to swap sleeves instantly while the dirty one is being cleaned and dried.
- This material keeps its snug fit around the filter even after multiple cycles through a washing machine.
What Users Say
- Growers who use these report their inline fans run cooler because the motor is not fighting against a clogged filter.
- Users who wash these regularly say their primary carbon filters last nearly twice as long as unprotected units.
- Buyers in high-traffic areas say these sleeves stop enough lint to keep their fan blades from becoming unbalanced.

Engineered specifically for 6-inch filters, this pre-filter is a perfect fit for compact ventilation setups in grow tents and other indoor gardens.

FAQs
The 1.8mm thick PP cotton acts as a barrier, capturing large particles like dust, hair, and pollen. This prevents the pores of your 6" air carbon filter from clogging, which maintains its odor-neutralizing effectiveness and significantly extends its lifespan.
Absolutely. The 6-inch size is perfect for the ventilation systems commonly found in indoor gardens, including the popular VIVOSUN 4' x 4' Smart Grow Tent Kit. It ensures your air remains clean without restricting crucial airflow.
No, the material is specifically designed to be highly breathable. It allows for unobstructed air passage, so your inline fan will continue to operate at its rated CFM without any added strain.
For optimal performance, we recommend washing the pre-filter every 2-4 weeks, depending on the dust levels in your environment. Simply rinse with warm water and mild detergent, let it air dry completely, and slide it back on. Maintaining a clean pre-filter is key to a healthy grow room environment.
Yes, we do. This pre-filter is also available as a 6" black pre-filter for a different aesthetic. If your ventilation system uses a smaller duct size, we also offer a compatible 4" white pre-filter.
