Culligan FM-25 Faucet vs Brita Basic Faucet Side-by-Side Comparison

By , , and ·Updated
Two faucet-mount water faucets, the Culligan FM-25 Faucet and Brita Basic Faucet, held side-by-side by a reviewer for comparison purposes.

Overall Verdict

The Brita Basic faucet filter lives up to its name … basic.

Although the overall design is good-looking, we found numerous manufacturing issues during our test. The most glaring one was that the filter cartridge fit so loosely to the filter compartment without us having to push the filter release button to the side. In fact, during one test, the filter cartridge even shot out of the compartment after we turned the tap on.

Performance is passable, with a good chlorine filtration rate, but its filtering flow rate is only mediocre at 0.7 GPM.

On the other hand, the Culligan FM-25 has a sturdier build quality while still having style with a glossy, chrome-plated housing. Performance-wise, the FM-25 also did well with a perfect chlorine filtration score. But it did even worse in the filtering flow rate department than the Brita Basic at 0.5 GPM.

All in all, both models have their drawbacks, but as far as value goes, the Culligan FM-25’s offer is far more compelling. Especially considering how the two models are in the same price range.
