Culligan FM 25 Faucet Mount Filter

I have chosen the Culligan FM 25 as my alternative pick because it has almost the same filtering power as the PUR PFM400H. The company states that it is NSF tested and certified and can reduce the amount of chlorine, lead, cysts, sediment, lindane, atrazine, particulate class 1, and turbidity in water.

It also uses a three-stage filtration system just like PUR PFM400H, but it is a bit more affordable. The only difference is that it does not have a light filter change sensor like the editor’s pick, but it has a bonus feature—a diverter valve stem for easy switching between unfiltered and filtered water and by vice versa.

Most users appreciate the excellent water flow that it delivers. According to them, it makes the unit more functional than most of its competitors.

Why Would You Need a Water Filter?

As mentioned above, one of the main reasons why I decided to buy a faucet water filter is to enjoy good tasting drinking water that is also perfect for making smoothies, coffee, and milkshakes. But there’s one more benefit that you should know.

With a faucet mount water filter, the water that comes from the faucet will also become healthier. This is because the filter removes or reduces the amount of bacterial and chemical contaminants that are commonly found in tap water.

Water filters are designed to remove chlorine. Chlorine is a chemical used by municipal facilities in filtering and disinfecting the water, but it has been linked to various diseases for the past few years. It can also remove heavy metals which may cause an imbalance in the body’s chemistry.

What to Consider When Buying Faucet Water Filter?

1. Size

The size of the water filter is relative to the size of the water filter cartridge. The bigger the cartridge, the bigger the filter will be. Although , the size is not that critical to the way the filter works, it can affect the amount of space that the filter will occupy.

If you have a spacious kitchen, you can go for a larger water filter, but if you have limited space, you should choose a smaller one.

2. Style

There are two types of water filter according to style. First, there is a type of filter that rotates around the axis. This style allows you to move the filter out of the way while you are washing the dishes.

The second style is one that swivels on a vertical axis which gives you unblocked access to your sink.

Both styles are good, so it will just be a matter of personal preference.

3. Finish

Water filters are available in various finishes and colors. I personally recommend going for a filter that is made of food-grade plastic to avoid any health problems.

Aside from that, other things to consider when choosing a finish are the color of your kitchen and faucet and the finish of the other appliances and fixtures in your kitchen.

4. Filter Cartridges

The cartridge is the one responsible for removing contaminants from the water.

When evaluating the cartridges of different water filter brands, there are a few things that you should consider—contaminant removal, filter capacity, and filter longevity.

Filter cartridges have a limited lifespan. The longer the lifespan of the cartridge is, the less frequent you would need to change them.

Filter capacities may vary from 100 to 200 to 300 gallons. The higher the filter capacity, the less frequent you will have to change your filter cartridge.

The most important thing to consider is contaminant removal. A standard water filter may remove around 40 to 60 contaminants. But a great water filter can remove up to approximately 75 contaminants.

5. Cost

In general, water filters are affordable. But more than its buying price, other things that you need to consider are its maintenance (cost of filter cartridge replacement) and installation cost.

6. Filter Change Sensor

As mentioned above, cartridges need to be replaced. While some manufacturers offer periodic replacement recommendation, there are some which provide water filters that come with a sensor that will notify you when it is time to change the cartridge.

There are two types of sensors. First is the light sensor that will turn red when the cartridge already needs changing.

Second, there’s the day counting sensor which is more common for water filter pitcher but can also be seen in. a few faucet water filters.

This sensor takes note of how many days have passed since you last change your cartridge. While it does not notify you that it is the time to replace the cartridge, it makes it easier for you to keep track of how many days have passed since you last changed it.


With the environmental problems that we are facing, it is a must now more than ever that we take extra precautions in ensuring that our drinking water remains healthy and the best way to do that is through the use of the best faucet mount water filter,

With the vast array of water filters in the market, it can be quite challenging to find the best one. But with careful analysis, I have come to the conclusion that the PUR PFM400H is the best option because of its affordable price and features—light change sensor, filtration power of more than 70 contaminants, and stylish design. While it comes with a few issues, its pros outweigh them all.
