Rated 3 out of 5 by Renz from Works, but needs more development. It works well and is easy to setup and use. However, I am only getting about 8-10 car washes with it, before the filter needs replacement . I conserve water when I wash my baby, so this is an expensive way to keep the car good. I am also encountering sediment from the filter making its way through, which can scratch the car's finish. So, this products needs more development for the price. The cost benefit, just isn't there in my opinion.

Rated 3 out of 5 by anqukaben from It works ...but.... This works well to remove the water spots from our too soft water here in texas. Here's a picture of the supply side to our pressure washer. The quick connects are perfect. On further research, I've learned these small horizontal models don't have much capacity. They absorb quickly. Horizontal isn't conducive to filtering/absorption. You discard the whole canister when it's spent. I've looked into models (yacht world) that have more capacity, vertical elements, a water meter (to tell me when the beads are spent) and replaceable beads. I'll try that type next

Rated 4 out of 5 by Jerry R from Works great - doesn't last long.... I am using this item as the water in my area is very hard. It absolutely softens the water and does not leave any water spots, so it does exactly what it says. The only issue is that it does not last long. I've gotten less than 10 washes out of it. I could go to a full service car wash for the same price. Not a great value, but like most people on Griot's, we like to wash our cars ourselves and when I do, this works.

Will this take calcium and metals out of well water?  How many gallons will it do?

Asked by: fiddleflyer

Yes, the deionizer will take the calcium and metals out the well water. Usually you would use that on the final rinse. The TDS range of filtered water coming out of the In-Line Water Softener & Deionizer all depends on the TDS level of the water going into the softener. The unit uses Ion exchange resin technology. The resin works by exchanging contaminant ions in the water with the hydrogen and hydroxide ions. The contaminants attach to the beads while the hydrogen and hydroxide are released into the water. Duration of the filter all depends on the TDS of the water going into it.

approx. how many gallons will this unit handle before a new filter is required?

Asked by: Chris W

The amount of gallons that this unit can handle before a new filter is required will depend on your TDS level (see chart on our product page).

How many washes do you get out of this before you need to replace the filter ? We have a lot of iron in our water.

Asked by: Miss350

The amount of car washes per filter can very greatly depending on your TDS level (Total Dissolved Solids) in your water. You can contact your local water company for the TDS level in your area, but for a more accurate reading you would need to test the TDS levels at your location. Our 33480 TDS Meter is great way to precisely identify your levels.

How many gallons/minute water flow?

Asked by: DRudd

The GPM or flow rate coming out of the In-Line Water Softener is completely dependent on the GPM or flow rate going into the softener from your faucet. The In-Line Water Softener does not noticeably restrict water flow.

Can you still eliminate water spots if you wash the car with regular tap water and then attach the filter for the final rinse?

Asked by: 327pickle

Yes most definitely. We would recommend washing the car, rinsing it once, then come in with a final rinse using the In- Line Water Softener & Deionizer.
