The WSP series spin down sediment filter is the first line defense to your appliances. It protects and extends the life of your standard filters by removing the large dirt, sand, and rust particles before they reach the rest of your plumbing system, including water softeners and expensive appliances. The WSP series is flushable and reusable. It is recommended to flush it regularly (daily or weekly), depending on the water usage, sediment amount and the hardness level. However, as hardness tends to form hard scale that clogs the screen, simple flushes may not be sufficient. When necessary, remove the stainless steel cartridge and clean it with a brush and/or soak it in vinegar. Water softeners and whole house systems usually do not lower the TDS level of the water. An additional reverse osmosis system may be necessary for your drinking water. Please consult iSpring professionals prior to purchase if you are unsure of which product will meet your needs.

It's really great! Better than I thought. I'm on a well, and it catches debris that could be in my filters.
