SiltSoxx RH Rice Hull Filter Sock
The newest, lightest filter sock for your BMP toolbox.
Filled with rice hull filter media and encased in our Original, Durable+ netting, SiltSoxx RH is lighter than a compost filter sock but heavier than a straw wattle – making it easier to handle and install, with the superior filtering performance that MKB products are known for.
Independent testing by TRI Environmental shows that rice hulls form an excellent high-flow, high sediment retention 3-dimensional filtering matrix when used in E&S tubular products. Rice hulls are a domestic by-product that comes from rice farming within the U.S. in California, Arkansas, the Gulf Coast, and in the Mississippi River Delta region.
Use SiltSoxx RH just like a compost filter sock or straw wattle for standard sediment control applications like perimeters, slope interruption, and other hard-to-reach project sites – no trenching is required.
If you’re looking for a more sustainable option, SiltSoxx RH is also available in our Natural+ biodegradable netting. This 100% biodegradable product eliminates the need for field removal and disposal, allowing you to leave the rice hull media on-site as a beneficial soil amendment, while also eliminating expensive labor costs and landfill tipping fees.
With SiltSoxx RH, you’ll save money, time, and achieve superior filtering performance. Ready to try SiltSoxx RH on your next sediment control project? Contact MKB Company today to find a distributor.

Frequently Asked Questions
SiltSoxx RH is a rice-hull-filled filter sock designed for sediment control on construction and stormwater projects. It is lighter than traditional compost filter socks while still providing robust filtration performance.
SiltSoxx RH uses rice hull media that is lighter and easier to handle than compost, while remaining more stable than straw wattles. This balance simplifies installation and repositioning on active job sites.
SiltSoxx RH is used for perimeter control, slope interruption, check dams, and other standard sediment control applications. It installs without trenching and conforms easily to terrain contours.
SiltSoxx RH is lightweight, easy to transport, and helps reduce labor during installation and repositioning. It also provides effective sediment retention while maintaining consistent water flow.
Compared to straw wattles, SiltSoxx RH features more durable, high-performance netting and delivers greater sediment retention. It stays in place more effectively and does not require trenching for installation.
Yes. The rice hull media supports soil contact that encourages vegetative growth over time, which helps improve long-term stability and soil health at the installation site.
SiltSoxx RH is commonly used by contractors, engineers, and stormwater professionals on construction, infrastructure, and land development projects. It is especially useful where filter socks need to be moved or reused frequently.
