AQUA CREST Inline Water Filter, Dedicated for Car Washing, Yard Cleaning, Reduce Hard Water Spots, Soften Water, Upgraded Formula with 1 Flexible Hose Protector

Saves water spots exactly what I bought it for

let me just say the water in my town is bad. REALLY bad. even when i go to pro wash places i still get waterspots at times. that being asid im wildly impressed with this little unit. i hooked it up with some quick couples i got at northern tool so that i could snap it on and off at will and i had low expectations to be honest. ... my porsche macan has a type of blue that shows EVERY flaw....well long story short after a simple 10 minute blast with the pressure washer i can find ZERO spots. not one! wow...just wow... 2 trips to the auto wash would cost more than this so needless to say im delighted.in addition i really didnt notice any restriction to waterflow as either and i know a lot of people complain about that with filters. not the case here.get it. you wont be sorry

Works great didn’t have any problems with filter

Did not reduce the amount of hard water spots left on my car after washing. Waste of money.Update 1: Seller reached out offering a refund since product did not work. I accepted to receive a refund and then they responded by offering other products which I was not interested in. They never sent a refundUpdate 2: The filter was still hooked up and it blew apart completely at the hose/filter crimp. Could have flooded my basement had I not been present when this happened.

Just washed my car for the first time with the filter. In addition, I used reinx spot free car wash. Kept the car in a shaded area. I let the car dry by itself. Only wiped out last few wet spots. I didn't see a single spot. The previous wash (without the filter and car wash liquid) was a complete disaster full of spots after the car dried.

We've used it once, to wash our car. Still left quite a few spots and residue. It might be because our area has very hard water. It may change as we use it, as I've read it takes a little to "break it in". Hopefully after a few uses, it improves.****It's been a bit, and I'm about done with my second filter (I bought three) . I've used them while washing my cars, house windows and solar panels.With our local hard water, these units aren't very effective. Sad to say, as I hoped they would help. After rinsing, there is significant spotting, unless I wipe the object dry immediately.And towards the end use of the second filter the spigot adapter broke. It just shot off from the fitting...The seller has reached out to me, and they are very nice. They are trying to make things right, but sadly I can't recommend this.****

Works great for washing the car

Rinsed my truck after washing with very low pressure in the evening. Let it air dry and the next morning it had almost no spots.
