FAQs on Melt Blown Filter

What contaminants does a melt blown filter remove?

Melt-blown sediment filter cartridges reduce particulate like sand, dirt, rust, and other sediment particles from water. This helps improve appearance of water, protects appliances and plumbing from sediment buildup, and helps protect other filter media cartridges in a water filter system.
No, generally a melt-blown filter is not washable or reusable. The dense filter media captures the sediment within, making it difficult to wash out once it is loaded with particulate. Instead, it is best to replace your melt-blown filter cartridge.
Yes, melt-blown sediment filters can be an excellent choice of pre-filter for your RO system. The media effectively captures particles like dirt, sand, and rust that can cause premature loading of the RO membrane. The sediment filter helps extend the membrane life.
The micron rating you choose for your melt-blown cartridge depends upon desired filtration levels, water quality, desired flow rates, application, and more. For most residential applications, 10-25 microns is adequate, but if you require a higher flow rate, 50 micron or higher may be the better choice.
Sediment filter replacement depends upon factors like water quality, usage, water temperature, water pressure, and more. Generally, you will want to replace your cartridge every 2-6 months. Once you notice a significant drop in pressure, it is most likely time for cartridge replacement.
