I've found that they last me about 2 months at most (I have 4 people in my house, 2 adults and two kids) before they look too disgusting to tolerate and I replace them. Lately I've found they last about 4 - 5 weeks at best before I need to replace them. If I do not filter the water then at times the water has an odd smell to it and my white clothes washing sometimes is not as effective as I'd prefer. So something seems to be getting worse. Perhaps it might be a seasonal/summer issue but I don't know.
I want to try and get to the bottom of what is really coming into my house and why it is always so dirty. I don't think I should need to replace filters every month.
Should I start with my local water district office or perhaps the DPW of my town? I'm wondering if they'll even do anything as they may tell me that no other residents have complained. I'm wondering if I should have my water tested and even send one of my gross water filters to a testing lab (again I'd like to get the town to pay for testing but they probably won't).
Thanks for your responses.
