The NP420 cartridge features the Neo-Pure sediment depth grooved filter with an added scale inhibitor. The design of the 5 micron grooved polypropylene sediment offers distinct advantages:

• No leachable chemicals
• High dirt-holding capacity
• Ability to withstand high temperatures
• More scale inhibitor than the AP420

Neo Pure utilizes a 5 micron polypropylene grooved sediment filter coupled with our scale inhibitor which is seven siliphos balls. These siliphos balls are held together in the center of the filter with netting, allowing for more contact time.

NOTE: Fits AP11T, AP101T, AP141T, AP102T, HF-360 and most other competitive housings that accept industry standard cartridges 2-1/2" to 3" OD x 9-7/8" L.
