The PUR FM-3700 Faucet Mount Vertical Chrome is an efficient faucet mount system that lets you enjoy the clean, fresh taste of pure filtered water directly from your tap.

This vertical-mount filter consists of a 5.5-inch long by 2.75-inch wide capsule connected to a small faucet mount head, which screws directly onto the end of a standard kitchen faucet. The capsule is designed to swivel so it rests sideways to allow regular tap water to be dispensed as usual, or in its upright position, which directs the flow of water through the filter for pure, cleaner-tasting water.

Styled in gleaming "chrome", white or black, this model blends effortlessly with traditional kitchen faucets. It can be mounted on most style faucets, including the tall neck or high-mount styles. Adapters are included for fitting non-standard threaded faucets. The only faucet style that won't work with this type of filter is the spray head style.

We found the installation to be quick and easy and were impressed at how smoothly the filter head swivels from one position to another. As you move the filter to the upright position, you'll notice a pause of just a second or two before the water starts to emerge. Likewise, when you switch it back to the horizontal (OFF) position, there is a slight trickle as the remaining water works its way out of the system.

This model comes with PUR's 3-stage filter cartridge -- the best in the line. The 3-stage filter removes 99.99 percent of microbial cysts, and reduces heavy metals, chlorine (taste as well as odor), benzene, and other contaminants. The PUR filter is NSF certified for the reduction of nearly 30 pollutants commonly found in drinking water, including asbestos, lead, mercury, carbon tetrachloride and more. Amazingly, it leaves behind healthful fluoride, along with a clean, fresh taste.

The 3-stage filter has one layer to trap sediment, a second to remove contaminants and a third layer of natural minerals, which leaves water as clean as can be. Our before-and-after testers actually noticed a difference in the smell and taste of the water. In fact, PUR is so sure you'll be delighted with this product that they offer a 30-day guarantee in addition to the 5-year warranty. A note on replacing the filters: It was somewhat awkward to unscrew the front panel and insert a new filter cartridge once the system was mounted on the faucet.


Pros: 3-stage filter for optimum quality, swivel design offers choice of filtered or unfiltered water, mounts directly onto faucet, small and unobtrusive
Cons: Can't be used with spray-head faucets, somewhat awkward to unscrew the front panel and insert a new filter cartridge once system is mounted on faucet
