We’ve used a whole house water filter for a long time now. The cartridges last anywhere from two weeks to two months, depending on the water supply. I’ve tried other approaches to a stand for the filter but after seeing others suggest using a traffic cone I decided to give it a try. I used the filter wrench to measure where to cut the top off and two minutes later the job was done. The filter slid right into the cone and it now stands upright. If you use a filter like this one this is an easy diy stand.
