800G under-sink reverse osmosis system with a mineral stage: what the 800 figure means, and the space and power it needs

This is an under-sink reverse osmosis system sold with an 800G rating, and the figure refers to the gallons the membrane can pass in a day rather than to a tank size, so it fills a glass quickly and does not rely on a pressure tank to keep up. The membrane is described as a Dow and DuPont type and the system adds a mineral stage after it, which is the part to ask about if what goes back into the water matters to you. Before ordering, measure the cabinet: an RO unit needs height for the housings, room for the tank if one is included, a drain connection for the waste line and a socket for the pump. Running cost is the part buyers forget, because the pre-filters and the membrane are consumables on different schedules, so ask for the price and the interval of each. What it will not do is work without a drain or a power point, and the exact filtration stages are for the seller to confirm.

Replacement filter for Brita-style water jugs, third-generation fit: match your jug model and check how the cartridge seats

This is a replacement cartridge from a third-party maker for Brita-style filter jugs, in the fit the seller calls the third generation. It is not an official Brita part, so start by reading the model on the lid or under the jug and comparing it with the compatibility list. The cartridge has to drop flat into the funnel and lock, because one that sits at an angle lets water run past the seal and nothing gets filtered. How long a cartridge lasts depends on your water hardness and how many litres go through it, so treat the seller's interval as a starting point and change it sooner if the flow slows or the taste shifts. What it will not do is soften hard water or fix a contamination problem, and for a workplace or a rental where you need paperwork, ask for the test report before ordering.
