Hello. Thank you for this inquiry. From purely a plumbing stand point, yes the Brita Redi-Twist 3-Stage Drinking Water Filtration System can be connected directly to your standard sink faucet; however this is NOT recommended for two reasons in particular: 1. The system's flow rate is certified at 0.5 gallons per minute (GPM); therefore to fill a sink or pot would require a great amount of time. 2. From a cost standard point, to use the system with an existing faucet for standard kitchen duties such as rinsing dishes, washing hands, filling pots, etc. would therefore entail filtering all water and necessitate the frequent replacement of filter cartridges.

Yes, the filtration system will reduce the salinity of your water.

It comes as shown in the picture with the filters.

Hi, The Filter D is a larger top than the other filters that go with the 2 or 3 Stage Systems. So, no other filters will fit into the D slot. Just like D won't fit into the other filter slots. D is a very effective filter against the bad microbes and other bad things that carry in water (read for self what it covers), especially well users. If there are nearby dairy, farm animals, or just animals, humans lol, and life itself, well D filter is needed! I am a huge pet/animal lover, so I have no issues with animals, just use Filter D, lol. Brita is a well known, long time company, and are the most reliable and very fair priced units and filters. Most homes don't need to change their filters until 6 months (their recommendation I believe). Us here, we do our own good water test, not the cheapy, from Home Depot, and we get closer to 8 months or so. The D Filter is not expensive if you do the math to a service of a water company who comes to your home, buy water containers from stores, etc, etc. Divide the cost by the months, trust me, very reasonable! Also, like I said, reliable! Enjoy. PS, we are on a big budget ourselves, 6 of us, and understand you, but we make it affordable, it's our safe water. Cut back other areas, and I mean that politely. :)

Not sure you're asking the right question. Are you asking about flow rate in gallons per hour (GPH)? If so, the answer is 60, derived from their published rate of 1 gpm.
