AQUACREST F-601R Filter Cartridge, NSF/ANSI 42 Certified, Replacement for F-601R Filter Cartridge (Pack of 2), Model No.WF05.

These are excellent replacements for my insane career insinuator hot and cold water system

I got them(2) in 3 days and installed it in 2 mins..

I found this to be the perfect substitute for the now discontinued F-601R filter cartridge from InSinkErator. It took me longer to clean out all the "stuff" (I'm being kind here) that was stored under the sink than it did for me to install this Aquacrest cartridge. It was just a quick unscrew of the old cartridge and quarter turn installation of this one. The whole process took less than a minute.It is impossible to know how well this Aquacrest cartridge removes particulates, chlorine and other chemicals, but it is certified the Water Quality Association, an independent testing organization. The filtered water tastes good enough in any case.

Have used these for a few years; decent filter.

Fits great, no leaks, would recommend. Disregard any review that may be negative if it is not a verified purchase.

Works great for my me, as well as any more expensive brand Ive purchased.

These are intended to replace the original F-601R water filter but they only remove residual chlorine and, apparently, small particulates. The original filters removed pesticides, herbicides and some heavy metals.

My in sink water heater is the old model, not many seller selling this type of filter now. This is just what I want, I like it.

Haven't actually used it yet but it looks the same as my existing cartridges
