For finer filtration ahead of UV or carbon, choose 5 micron. For maximum fine particle removal including Cryptosporidium cysts, choose 1 micron.

It can simplify your system by removing the need for a separate pre-filter stage. It's rated for small homes with one bathroom (up to 38 lpm). The trade-off is a lower flow rate than the standard polyspun variants and no WaterMark certification.\u003c\/p\u003e\n\n\u003ch3\u003eCan I clean and reuse this cartridge?\u003c\/h3\u003e\n\u003cp\u003eNo. Polyspun cartridges are not cleanable.

AS\/NZS 4020 means it has been tested and approved for use in contact with drinking water.

The Dual Gradient variant is not AS\/NZS 4020 certified.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the difference between polyspun and pleated cartridges?\u003c\/h3\u003e\n\u003cp\u003ePolyspun cartridges are disposable — they cannot be cleaned and reused. They use a depth filtration structure rather than a surface filtration structure. Polyspun is typically used for finer sediment removal in the second stage of filtration; pleated cartridges are more common as a coarser first stage. Polyspun also tends to have a higher dirt-holding capacity for fine particles.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need special tools to change the cartridge?\u003c\/h3\u003e\n\u003cp\u003eYou'll need a housing wrench to open the filter housing — most housings include one.
