1 / 7iSpring WSP500J Jumbo Spin-Down Sediment Filter, 500 Micron
The iSpring WSP500J is a jumbo spin-down sediment prefilter with a 500-micron screen, designed to intercept larger particles before they reach downstream filters and plumbing. Its reusable, flushable design and stated 25 GPM maximum flow rate may suit homes dealing with sediment, particularly from well water, but the screen is intended for larger particulates rather than fine filtration.
At a glance
- The manufacturer describes a 1-gallon capacity and says it is 22 times the capacity of traditional sediment filters.
- The 500-micron screen is intended to capture larger material such as dirt, rust and sand, not to perform fine-particle filtration.
- Flushing the reusable screen is presented as a way to reduce replacement needs and lessen the load on filters farther downstream.
- The clear housing lets users see inside, while the listing specifies 1 inch MNPT and 3/4 inch FNPT connection options.

Pros and cons
Pros
- Reusable, flushable filtration avoids routine replacement of a disposable screen, according to the product description.
- The listed 25 GPM maximum flow rate and 1-gallon capacity are relevant to whole-house prefilter use.
- Included contents list specifies a housing wrench and bracket, in addition to the manual.
Cons
- A 500-micron screen is aimed at larger sediment and is not a substitute for finer filtration or treatment of contaminants not identified as captured particulates.
