Great tool.......

We are glad that we got the water filter tool as it was much easier to change the filters with this device. Especially if you can't fit your hands really inside to turn/change the filters out. We would recommend getting this tool when changing your water filters.

Tough to remove Pre-Filter and Carbon Block filter

I reviewed the Youtube video and tried to replace filters. But it is impossible to remove Pre-filter and Caron Block filter with my hands. Onlipure Post Filter is trapped with a plastic tie. I cut the tie off then it was removed with some effort. I waited for a while and twisted Pre-filter and Carbon Block filter several times a day with the Onlipure post filter removed. Need to use both hands on the side of the filter and twist with full strength. You see the white part moving in the small window above. It is no way that I can twist from the bottom of the filter with one hand. This is a trick. Instead of following youtube video, 1. Remove the onliPure post filter first. Follow the youtube video. This will give you more room to work on. 2. Then remove the Carbon filter. But need to use two hands to hold the filter from the side. Do not follow youtube videos. 3. Then Pre-filter. But need to use two hands to hold the filter from the side. Do not follow youtube videos. Then I finally succeeded in twisting the filters out. So, I did not purchase a strap ranch. It may be easier when water is drained more from the filters. I still like this water filter.

Entire system a waste

Purchased a system a year ago. Bought filters and then can’t change them because the bottom screw won’t come out… have tried everything. So, basically the entire system was a waste of money.

Extremely useful

This strap wrench made taking out filters in order to replace them extremely easy.

Must Purchase with Replacements

The videos describing how to "easily" remove the filters fails to explain that removing the older filters is extremely difficult due to suction and water contain in the filters when trying to remove for replacing. The Strap Wrench is the ONLY way to remove the used filters to replace them. Had to find one at hardware store to continue with replacing the filters.
