I bought a 2-pack.  The first filter had a normal flow rate & I was happy.  It lasted 6 months until I replaced it as the water flow got slow. The second was installed and worked fine for 3 weeks then the flow rate was soooooo slow I need to replace it . I think this company has quality control issues.
Will not buy again.
