Buying Guide
What to consider when choosing 4 inch filter socks:
- Micron rating: Higher micron numbers trap finer particles but may slow flow. Choose 150–200 microns for balanced filtration with healthy flow for most setups.
- Material and construction: Felt and woven polyester offer durability and reusable options. Check stitching quality for long-term use.
- Size compatibility: Confirm the sock diameter and length fit your sump rings and filter sleeves. 4 inch rings are common, but some systems require exact dimensions.
- Quantity: Larger packs reduce replacement frequency and shipping noise for busy tanks. Consider your maintenance schedule and water change cadence.
- Reusability: Reusable socks save cost over time but require thorough cleaning between uses. Ensure the material tolerates repeated washings.
- Compatibility: Some brands may not fit specific filter brands or models. Verify with your sump and filter system before purchasing.
