Culligan FM-15A vs FM-25: What’s the Difference?

The only difference between the Culligan FM-15A and FM-25 faucet-mounted water filters boils down to the color. While the latter has a chrome finish (plastic with a chrome coating), the Culligan FM-15A faucet filter comes in a white plastic design.

A multitude of people gravitates more towards the Culligan FM-25 because the chrome design meshes well with other kitchen fixtures and is more eye-catching than the FM-15A. Nonetheless, both units get the job done in boosting the quality of water when it comes to functionality.

Culligan FM-15A and FM-25: Features

When comparing the Culligan FM-15A vs FM-25, both units do an excellent job in engineering the seamless functioning of the filters with standard taps. Simply install them on your sinks’ nozzles, and you’re good to go. Given that the only variation between both faucet filters is the aesthetics let’s explore their incredible features.

Intricate Design

It’s no secret that most filters come in a size that makes mounting an uphill task. As a result, large water filtration systems require more room to accommodate them. The Culligan FM-25 and FM-15A come in a compact design that won’t occupy too much space. Despite being among the smallest in the market, both filters compete aggressively with their larger counterparts.

Presentation and appearance are other features of Culligan that easily sell the brand’s products. Granted, the FM-25 and FM-15A don’t actively participate in the filtration process. However, you need products that serve with confidence. Therefore, the structure sets both units apart from the pack. Furthermore, the chrome finish of the FM-25 makes it stand out.

Filter Pore Size

It’s worth noting that one common aspect with all filters is the plate on which tiny impurities don’t pass through. The plate has different pore sizes that vary from one brand to another. The openings are too tiny for the human eye to notice their presence. They are tinier than 1 meter by a million times and are measured in microns (millionths of a meter).

The micron rating represents the smallest size of impurities that a filter will allow per liter of water. Contaminants such as fungal spores, bacteria, and fine dust particles won’t pass through the holes. It’s this feature that makes the Culligan FM-25 or FM-15A a worthwhile investment.

Flow Rate

The liquid is in contact with the micro-filter holes through the water filtration process to ensure its release through the tiny openings. It’s this barred restriction that is crucial in removing contaminants. For most filters, the procedural purification takes an hour or more, but with the FM-15A or FM-25, the wait time is a few seconds to filter enough water to fill a glass due to the impressive flow rate of 0.5 gallons per minute (GPM).

Filter Life

It’s a crucial component to consider when choosing a faucet mount water filter for your home. While there’s no shortage of filters costing $10 or less, they have a short lifespan. The FM-25 and FM-15A will set you back $25 to $30 but will give you the best bang for your buck. With proper maintenance and installation, these units can filter up to 200 gallons before a replacement is due.

Nearly all components of these filters usher in additional perks. For instance, with the diverter tab, you can bypass the water purification process to opt for tap water, which comes in handy for house chores.

Installation

Setting up the Culligan FM-15A or FM-25 is fast and easy without the need to rope in a plumber or use tools. The manufacturer included a few adapters that are a snug fit onto standard faucets to make the process easier. To get started, remove your faucet’s aerator and try on the different adapters until you find the perfect fit. You have free rein to use a new washer or the one you have on the faucet.

Secondly, tighten the adapter and screw on the Culligan faucet mount filter. Thirdly, when it’s properly in place, pull the diverter and get the water running. Let it run for up to 5 minutes as you keep your eyes peeled for any leaks. Lastly, after 10 to 15 minutes, the carbon filter will have flushed, and your filtration system is ready for action.

Support and Help

Culligan is one of the most reputable brands in the water filtration industry. It’s, therefore, no surprise that the Culligan FM-15A and the FM-25 come with a 2-year warranty. Additionally, technical support is a phone call away with a customer care agent always ready to assist.

Culligan FM-15A and FM-25: Benefits

Let’s delve into a few perks of installing the Culligan FM-25 or FM-15A faucet water filters in your home.

1. Elimination of Impurities and Contaminants

The main function of a faucet mount filter is to produce healthy, odorless, and pure water. The Culligan FM-15A and FM-25 can eliminate a boatload of contaminants such as rust, bacteria, dust, dirt, lead (up to 98.8%), chlorine (more than 97%), herbicides, insecticides (lindane and atrazine), cryptosporidium, and giardia cysts.

These can be detrimental to your health and impact the overall quality of your water. If you use well water for your business or home, these faucet water filters effectively remove the various contaminants and impurities.

2. Improves the Taste of Water

Many people spend hundreds of dollars on bottled water because they can’t stand the taste of tap water. The Culligan FM-15A and FM-25 faucet filters are a cost-effective way of removing the contaminants and chemicals that give water an unpleasant smell and taste, ensuring crisp, clean, great-tasting, and odorless water.

Impurities such as sulfur and rust give water a distinctive discoloration, odor, and taste. If your water supply contains high levels of these impurities, the FM-15A and FM-25 will make all the difference.

3. You Can Alternate Between Filtered and Unfiltered Water

For a myriad of people, they prefer the option of switching from unfiltered to filtered water (and vice versa), as they deem necessary. For instance, if you prefer to use cold water for household chores such as washing dishes, watering your plants, and wiping surfaces, using filtered water might be unnecessary. Therefore, with the FM-15A and FM-25 faucet filters, you can use filtered water for consumption.

4. Professional Installation Isn’t Required

The good news is that you don’t have to be mechanically skilled to install the FM-15A and FM-25 faucet filters. The installation process is fast and easy, saving you the cost of roping in a plumber. They come with comprehensive instructions for installation, walking you through the process step-by-step.

Additionally, the filters come partially assembled, which means you’ll only need to install the faucet and attach your filter to the cold water pipe of your sink. That requires little to no skill.

5. Space-Saving

Given that you can store the FM-15A and FM-25 faucet filters under your sink, you can save on counter space while enjoying clean drinking water. Granted, countertop filters can be relatively bulky and unsightly. However, these faucet mount filters can be neatly tucked away in your under-sink cupboard. Alternatively, they can be laid on their side to save more space if need be or mounted on a wall.

6. Cost-Effective

There’s no denying that the long-term cost of bottled water can be relatively high. Contrary to reverse osmosis units, there’s no water wastage with the FM-15A and FM-25 faucet filters during the purification process. Therefore, your water bills won’t be impacted. The replacement filters are pocket-friendly, and you’ll only require purchasing them after 200 gallons of water has been passed through.

7. Based on Your Water Filtration Preference

The FM-15A and FM-25 faucet filters have various functions for eliminating chemicals (chlorine), contaminants (lead and rust), bacteria, giardia cysts, sediment, and larger grains. Additionally, you build onto these units by adding a separate re-mineralization filter that infuses magnesium and calcium into the water for reduced acidity. If your water source is a well, these faucet filters are tailored to purify it and make it fit for consumption.

FAQ

Here are a few answers to some of the most commonly asked questions about the Culligan FM-15A and FM-25 faucet filters.

Does the FM-25 or FM-15A fit on a bathroom sink faucet?

The filter mount includes adaptors for standard faucet end threads. However, bathroom faucets are more chic, modern, and typically wider than kitchen faucets of 1-inch diameter.

Although thread adaptors should perfectly fit bath sinks, if the faucet head surpasses a width of 7/16 inches, which is wider than a spigot hole, then the housing is incompatible. Additionally, consider how much these faucet mount filters will limit access to the sink.

Does the FM-15A or FM-25 remove fluoride?

While the units effectively get rid of various contaminants and impurities, they are ineffective against fluoride.

Is color the only variation between the Culligan FM-15A and FM-25?

Yes! While the FM-15A is white, the FM-25 has a chrome finish to match the faucet, which most people prefer aesthetically. When it boils down to functionality, there’s no difference between both units. They work seamlessly to purify water.

According to the manufacturer, the water is meant to flow through the FM-15A or FM-25 filter rather than the sink. How should you turn the three knots for the water to pass through the filter?

You shouldn’t need to turn the knots in any particular direction, as their sole purpose is to make it easier for you to unscrew the filter from the housing. For water to pass through the filter, pull the knob on the side to automatically switch from the faucet.

If you want hot water to rinse or wash, does the Culligan FM-15A or FM-25 come with a switch or lever?

The faucets are used as normal for cold or warm water. When you want to use the filter, pull the small knob found on the opposite end of the faucet. Although it’s intended for cold water use, water exceeding 100℉ shouldn’t pass through the filter as it significantly lowers the lifespan.

Does the Culligan FM-15A or FM-25 come with a filter change indicator?

No! For optimal efficiency, replace the filter after 200 gallons (every two months) or when you notice a significant decline in the water flow rate.

Does hard water affect the cartridge?

No! Minerals don’t impact the longevity or performance of the Culligan FM-15A and FM-25 faucet filters.
