What's the Difference Between String Wound Filters and Pleated Filters?

In this article, we will introduce two common types of filters but many people are confused about the difference: pleated filters and string wound filters. After reading, I believe you will have a better understanding of sediment filters.

Write in front

Both pleated filters and string wound filters are sediment filters. The purpose of a sediment filter is to remove suspended particles or colloidal substances from the water source. If these contaminants are not removed, they can cause damage to other delicate filtration membranes in dialysis water or even block the water circuit. Note that when choosing a pleated filter or string wound filter, make sure there is a sediment contamination problem in your water.

The smaller the micron count, the more detailed the contaminants can be captured. Of course, you will need to pick and choose based on your water quality. A filter that is too tight will lower your water pressure.

String wound filters

String wound filters belong to the depth filter. Designed with a thin dense honeycomb structure of being dense inside and sparse outside, the rope filter has strong dirt holding capacity. They are more effective when a wide range of particle sizes is required. Compared to pleated filters, string wound filters have the advantage of depth, although they do not have a larger surface area.

YUNDA String Wound Filters

These string wound filters are certified by NSF 372, which means lead-free and BPA-free. Reduces sediment, rust, scale, dirt, sand, silt, bad taste, and odors. Designed with a dense inner and outer structure, it has a high precision filtration of 5 microns. With 3D structure, which can effectively capture particles and sediment targeted, providing stable and continuous high water flow.

Pleated filters

As the name suggests, it is a surface filter that increases the surface area of filtration by means of pleating. They provide "depth" filtration and remove more contaminants, and large and fine particles from drinking water, such as sand, dirt, silt, and rust particles.

Some businesses will use higher quality materials so that they are easy to clean and can be rinsed and used repeatedly, reducing the number of filter replacements.

YUNDA Pleated Filters

This pleated sediment water filter is tested and certified by NSF International, with NSF/ANSI (American National Standards Institute) 50 certification. Also passed NSF 372 certified, with lead-free and BPA-free. The filter is durable and easy to clean. Has a longer life than ordinary filters.

We hope this article can give you more understanding of string wound filters and pleated filters. Suitable for different filtration systems they will be available in different sizes, like RO systems, whole house systems, and so on. Please contact us with any questions.
