You’ll buy salt bags every month. A 40-pound bag costs $5 to $15. Over a year, that’s $60 to $180. Not huge, but it adds up faster than your gym membership subscription.
Then there’s electricity. A softener uses about the same power as a nightlight. So, like, $5 a year. That’s cheaper than a single latte.
Also, water for backwashing. You’ll flush 50 to 100 gallons during regeneration. That’s basically a small swimming pool every week. Have fun explaining that to your water bill.
