Premium Cotton Acetate Filter Rods Bulk Pack 3990 Count Diy Air Filtration Media

A tight cylindrical profile and consistent white cotton acetate construction make these filter rods a practical choice for builders of custom air filtration systems, HVAC retrofit projects, and workshop purifiers. The uniform density across each rod means predictable airflow resistance whether you stack them, trim them, or pack them into non-standard housings.

• Each rod measures 3.8 inches long x 0.3 inches in diameter, cylindrical form factor suited to standard and custom filter housings
• Bulk pack contains 3,990 individual rods with a total weight of 6 lbs, reducing repackaging frequency for high-volume filtration applications
• Constructed from premium cotton acetate fibers that deliver consistent density, low airflow resistance, and reliable particle capture efficiency
• Lightweight and uniform build allows rods to be stacked, trimmed, or layered with other filter media to match non-standard core dimensions
• Compatible with vapor filtration, particle separation, lab equipment, and select liquid pre-filtration setups where cotton acetate chemical compatibility has been verified
• Ready to load directly into a filter core or canister with no additional preparation required

Features

• 1. High-Performance Cotton Acetate MaterialMade from premium cotton acetate fibers, these filter rods offer excellent filtration efficiency, low resistance, and consistent density. Ideal for air filter cores where reliable particle capture and air flow balance are critical.
• 2. Precise Size for Versatile ReplacementEach rod measures 3.8" in diameter x 0.3" width x 0.3" height (2.8 cubic inches). The compact cylindrical white design fits many standard and custom filter housings, allowing you to cut or combine rods as needed for different core sizes.
• 3. Bulk Pack of 3,990 Pcs – 6 lbs TotalOne bag contains 3,990 individual rods, total weight 6 lbs. This high-quantity pack reduces repackaging frequency and is cost-effective for continuous or high-volume filtration applications, such as workshop air purifiers or HVAC retrofits.
• 4. Easy to Install and CustomizeThe rods are lightweight, uniform, and ready to use. Simply load them into your filter core or canister. They can be stacked, trimmed, or combined with other filter layers to adjust density and fit non-standard dimensions.
• 5. Broad Application – Not Limited to Air FiltersBeyond air filter cores, these cotton acetate rods work well in vapor filtration, particle separation, lab equipment, and some liquid pre-filtration setups where chemical compatibility with cotton acetate is verified. Always test for your specific fluid or gas environment.
