2 Reasons to Use a String Wound Filter in a Whole House Water Filter System

A whole house water filter system is an easy way to get clean, better tasting water out of every faucet in a house. At the core of every whole house water filtration system, there is a filter cartridge. There are many different types of these filter cartridges on the market today, so here are two reasons to choose a string wound type of water filter.

1. The Choice of String Materials

Unlike a carbon filter, the string that comprises a string wound filter can be made out of a variety of different materials. Depending on the type of debris that needs to be filtered out, different types of string material may need to be used. For instance, Teflon and polyester strings will filter debris as small as 20 microns in size. Polypropylene stings, on the other hand, can filter debris as small as a half of a micron in size. The trade-off of using a string that will filter tiny debris, however, is the ease with which water will flow through the filter. If one needs the water to flow more quickly and easily through a filter, a larger string material (like the Teflon, polyester, or even cotton) should be used.  

2. Prevents Leaks and Pressure Drops

Filters that are made out of a mesh material that is bent into a cylinder shape can begin to weaken along their seams. This can allow contaminated water to pass through the filter unabated and could cause a sudden pressure drop in the water system. These problems cannot occur when using a string wound filter, because of the manner in which the filtering string is continuously wrapped around its core. Since the wrap is continuous no seams exist, totally eliminating the possibility of failing seams letting water through or affecting the water pressure.
