Currently use a Brita filter as its enough to take the chemically smell from my tap water. Espresso machine has a built in water softener that I change every six months or so. It isnt the most efficient way to do it but the machine does not have any build up when I have checked, my water tastes neutral and nice to drink if not amazing.
Long term I want to build in a proper water purification, strip, and remineralization solution into my mains supply when I get around to redoing the kitchen. UK is low risk for water contamination but we do have recent incidents of it happening so its not zero risk and I would rather not take the risk with the way our water companies are ran.


When my kids were kids it really depended on if they needed anything big. One year we would get them a macbook because they needed a new laptop for school but then it would last nearly five years so I wouldn't have to buy another one for ages. Same for things like phones or consoles or. I always spent more on these big purchases as they normally last longer.
Now they adults I spend a few hundred for birthdays and Christmas. I like to get something they will actually use, will last, and is memorable. The best gifts show that you actually pay attention to their current hobbies or are something they would want but would rare splash for. Example would be for my sons birthday i got him a GBA SP style emulator and loaded it up with pokemon roms, official and fan, as I knew he had a few months off studying for his professional qualification.
