This item removes minimal dissolved solids (TDS’s) from city water. Measured change in TDS using two separate filters was around 13% and reduction drops off rapidly on subsequent checks within a 1 hour period. Bought these guys for rinsing cars after washing…cannot recommend them for this purpose, ie spotless rinsing without having to towel dry.

It doesn’t remove all the calcium from your water but removes some of it. I’m not sure what time frame for the stated one month replacement would include daily use or weekly use or exactly how much water would it require to be run through it to be replaced.

This filter helps but still leaves hard water spots on your car. Maybe it’s works better for other purposes.
