Pre Fresh Hose-end Water Filter for Filling Pool, Spa, Hot Tub & spot-Free Car Wash

Every year we have problems when we top off our above ground pool with water from our house water. We have well water and that’s a lot of iron and other minerals that would turn the pool water brown every year. Then spent lots of money on chemicals to get it filtered out and also new filters For the pump. This year we tried this filter and topped the pool off with over 12 inches of water over a two day period. It has now been two months and the water was always crystal clear. If pool gets low on water from loss due to heat snd sun we just attach our hose to this filter and throw it in the pool for an hour or so. Works great!! Great product would recommend this to anyone wanting to filter out water they add to their above ground pool from well water.

Bought this to use for wa shipping my vehicles. There water in southern California is extremely hard and if to have a black truck like I do it can make washing a vehicle very difficult. This gave me instant results. It attaches to the edge of the house perfectly and I was able to put a nozzle on it without any leaks. There's a slight drop in water pressure but it's perfect for my needs. I can't stress how much of a difference this makes. No water spots are left behind and the truck is shining.

We have very hard well water and it took a ton of chemicals to get ph even close to where it’s supposed to be in our hot tub. Bought this, filled hot tub with it, PH and hardness were almost spot on at initial fill!

My water is nasty however, and nothing can filter out the minerals in this stuff.. No worries though. I just wish I could find another use for this. Maybe when I own a home one day.

Either the filter I received is defective, or it is so effective it filters out the actual water! The flow started out as no more than a trickle and slowed down to mere drops coming out. It is completely useless for filling a hot tub. I’d literally get quicker results using an eye-dropper! Unfortunately I purchased this several months before using it, so the return window has long since closed, or else I would have returned it immediately.

Use this on your hose if you have hard water and it'll clean that water right up.

At first the package arrived with absolutely nothing in it. I thought it was a sick joke at first but I am guessing there must have been a mixup at the warehouse. Customer service promptly resent the item. I tried to post this comment twice but it seems to be censored for some reason. Once I finally received the product two weeks after ordering, it was okay. I attached it it my hose to fill my pool and remove the iron content. It helped minimally but did not filter out as much as I had hoped. When I shocked it, I was still stuck with the obligatory brown water water until I filtered it out for two days. I do have to say it was a bit of a shorter time to clear the water but not worth the cost of the product.

I used the Pre Fresh to fill up my new hot tub. I live in an area that has very hard water and am pleased to report that when I filled up the tub the water was crystal clear and only required me to add in chlorine. I purged the Pre Fresh for 30 seconds to clear out all the black stuff then started filling up the tub. I also used it to wash my truck and it worked like a charm. I would highly recommend this product to wash your vehicle or start your new spa off with clean soft water.
