Culligan FM-25 Faucet vs Wingsol Faucet (WS-FM001-PAC) Side-by-Side Comparison
Culligan FM-25 Faucet
Wingsol Faucet Water Filter

Overall Verdict
The Culligan FM-25 is a better buy than the Wingsol faucet filter (WS-FM001-PAC). Besides having much better build quality, the filtering action of the Culligan is stronger, too.
In our chlorine test, the Culligan FM-25 neutralized all traces of chlorine from the flow of high-chlorinated water that we pumped through it. The Wingsol, on the other hand, left a small amount of chlorine that our kit can still detect. It’s one of two filters in our list that didn’t have a perfect score in the chlorine filtering section.
As a result, while it’s a lot more expensive than the Wingsol, the Culligan FM-25 will still be a better option if you have a roomy budget to spare. But if not, more attractive budget-friendly options are available, such as the Waterdrop WD-FC-01.
