The Importance of Filter Socks

Usually things are said to need filters or filtration, so it can seem strange to hear that filters need something, too. Filter socks help filters do their job well, and they play an important role in the overall filtering process.

What Are Filter Socks?

A filter sock is an additional layer that fits on the outside of an inline filter core and is held in place by a retaining ring. It can also be used over an existing inline filter, thereby increasing filtration power and preventing the underlying core from getting clogged.

What are Filter Socks Made From?

Mesh sanitary socks are typically made from some sort of fabric. We offer them in cotton, rayon, polyester, and nylon. Which material is best depends on your application and what is being filtered. Typically, they are sold in bulk packs of 50 or more since they are intended to be used only once.

Why Use Filter Socks?

Socks are often preferred to the alternative of adding a wire mesh to the outside of the filter core. Wire mesh can be effective, but since it’s meant to be reused, it has to be cleaned. It’s also costly to get differing sizes of mesh. Using socks eliminates that cleaning step, thereby cutting downtime and labor costs. The disposable socks are also much more economical, so it’s not financially painful to switch them out as your facility runs different products.

Are Filter Socks Sanitary?

Our industrial filter socks are made to be sanitary since they are commonly used in commercial food production systems. That said, not all manufacturers make their socks with this in mind. Always be sure to verify the intended purpose of filter socks so you’re getting the ones that will meet your needs.

What Types of Filter Socks are There?

We make several varieties of filter stocks on an ongoing basis. These include woven and non-woven rayon, smooth weave Dacron, cheese cloth, cotton flannel, and many more. We can also produce custom versions to meet your needs. With our filter socks, there’s no need to try to make do with “almost right.”

  • Socks are made of fabric instead of metal
  • Since filter socks are disposable, they come in large quantities
  • Changing from one type of sock to another is easy and economical
