Significant Difference between String Wound Filter with Melt-Blown Filter:
Flow Rate: String Wound Filter  > Melt-Blown Filter
Dirty-holding Capacity: String Wound Filter  > Melt-Blown Filter
Service Life: String Wound Filter  > Melt-Blown Filter

Safety Material:
Food grade 100% Polypropylene material, Lead and BPA-Free. Non-toxic, odorless, no leaching or secondary pollution. Providing a healthy, safe water-filtering experience.

Standard Size:
20" x 2.5" universal filter cartridge size, fits most 20-inch filter housings. Used as a prefilter for reverse osmosis (RO) and whole house water filtration systems, and various commercial and industrial applications.

Unique Honeycomb Structure:
The string wound filter has a deep graded honeycomb structure, dense near the inside core and more open and sparse near the outside edge, forming an effective depth filtration filter, catching larger particulates first and then smaller near the center core, effectively increasing the dirt holding capacity of the filter.

High Efficiency Filtration:
Removes up to 99% of sediment, including rusts, silt, sand, and other undissolved particulates from feedwater. As the first-stage filter in the whole house filtration system, it protects your post-filters, water appliances, pipes, bathroom, and kitchen faucets and shower fittings from clogging, providing a healthier filtered water supply for your home.

Long Lifetime:
Our high dirt-loading capacity sediment filters can last up to 40,000 gallons. For better water quality, recommended replace it every 6 months, depending on the quality of the original water source and application type.
