how do you clean this?

I just cleaned mine for the first time last week (8/7/2019) gently using a medium brush while dipping the filter in a bowl of water. It came clean enough to restore flow in the house. Very satisfied.

Is the 50 micron and the 100 micron interchangeable? Van it be used with the 100 housing unit?

Hi, Yes the cartridges can be interchanged in the WSP Series spin down filter. You can use the 100 or 50 or any other size Micron screen. Thank you, iSpring Water Systems LLC

What size is the filter

The replacement screen is approx. 1.5" x 4.5"

Does this fit WSP-50?

Hi CK, Yes! this is exactly the mesh cartridge for the WSP50-50. For more questions, please reach out to our customer service team. We're always ready to help. iSpring Water Systems, LLC
