About this product
This is a 3M replacement cartridge carrying the model LR400-JX90, sold as the consumable for an under-sink water filter rather than as a complete system. The whole question is which unit you own: the cartridge number has to match what is printed on the housing or on the old cartridge, because a filter that only looks similar will not seat or seal on a different head. Changing it is a twist-out, twist-in job at the housing under the sink, and it is worth shutting the feed and putting a towel down, since the head keeps water in it. How often it needs changing depends on the litres you draw and on your water quality, so the interval on the label is a starting point rather than a rule. What it will not do is turn your system into a different model, and the filtration performance and test data are the manufacturer's and the seller's to supply.

Pros & cons
Pros
- Model number LR400-JX90 is stated, so it can be checked against the housing before you pay
- Cartridge-only replacement keeps the existing head and plumbing in place
- Twist-fit change at the housing, so the feed lines do not come apart
- One cartridge costs far less than replacing a whole filter system
Cons
- Only fits heads that take this number; a similar-looking cartridge will not seal
- Filter performance and the change interval depend on the unit and your water, ask for the data sheet
- The head holds water, so the swap needs the feed shut off and a towel underneath
