The difference between the FM15 and FM25 is the color variation. The FM-15 is white coated while the FM25 and FM100 are chrome coated. The FM differs from both due to the filter lifetime indicator which sends you a reminder when it’s time to replace.

What to Expect From Culligan Faucet Filter

Filtration capability

It is certified in accordance with NSF/ANSI 42 and 53. NSF/ANSI standard certification 42 means that the unit primarily focuses on chlorine taste, odors and sediment. A further Standard 53 certification means that the filter is really effective in filtering high level contaminants such as Lead, turbidity, lindane, atrazine, microorganisms like Cryptosporidium and giardia, and other dangerous contaminants that nobody wants to drink.

This filter does not reduce the TDS in water, which can include minerals, salts, or metals. A TDS meter measures total dissolved solids. It is unclear what solids are in the water.

The filtration process is carried out by a 1-stage filtration system with a micron size from 0.5 to 1 micron. This micro rating is quite effective in eliminating 99.9% of these contaminants. However, this filtration system only works on soluble ions.

Maintenance and replacement

What to Expect from Pur Faucet Filter

Filtration capability

It is certified to remove up to lead, mercury and pesticides that contaminate your water. PUR faucet filters contain blended carbon and ion exchange material to remove as many contaminants as possible. As the water flows through the filter, contaminants such as pesticides and industrial pollutants are absorbed into the carbon. The ion exchange absorbs heavy metals like lead and mercury. 

Activated carbon particles attract and remove these contaminants. The filter is a solid block of activated carbon particles compressed into a dense material through which water has to pass.

The NSF International, an independent laboratory that verifies and certifies filters, does not establish a micron rating for carbon water filtration systems. However, PUR filters have an NSF rating 42 certification, 53 certification, and 401 certification and have been designated by NSF International as Class 1 for nominal particle reduction.

A Class 1 particulate reduction claim means that the filter will reduce a minimum of 85% of the particulate matter between 0.5 and more than 1 micron. Microplastics, which are approximately 2.5 microns in size, would be categorized as NSF class I particles and would be reduced by PUR filtration systems.

Maintenance and replacement

Pur faucet filters have an inbuilt LED indicator that powers the CleanSensor™ Monitor on the purifier and keeps track of the filter life and alerts you when to replace the filter. The green light on the LED indicates that the filter is in normal operation.

Yellow indicates its time to consider replacing the filter, whereas red means that you need to replace the filter immediately because the faucet does not filter. It usually takes place every 3 months or 100 gallons, but it depends on how the filter is used.

Filtered Water vs. Bottled Water, Which Is Better?

best faucet filter from reddit

Everyone is aware of the advantages of drinking distilled water. It is safe to drink. Bottled water is good, but unfortunately, the adverse effects on the environment of its consumption and economic load outweigh its benefits. For these reasons, an increasing number of people are turning to filters to keep their water safe. If you have purchased bottled water to ensure that your water is clean, now is the time to switch to water filtration.

You will have clean and healthy water, which is the safest to drink, without any expense and bottled water issues. You will be surprised about the cleanliness and the smell of your filtered water will be free, and you will also know that the water is healthier. To continue to have clean water, it is essential to replace your filters after 6 months, and you will still have clean water.

How to Install Faucet Water Filters

There are two ways to install the tap water filter. The first method is to screw it onto the end of your kitchen faucet and the second way is to type it into your cold water line just under your sink. These methods are straightforward to use.

Faucet-mounted filters often require special adapters or don’t fit on faucets at all. If the filter or adapter doesn’t sit properly in the housing, some water could bypass the filter and go straight into your drinking glass.

To attach these filters, you first have to remove the faucet’s aerator—a small disc screwed onto the faucet tip that controls water flow—to reveal threads below.

  1. Step 1: Remove Faucet Outlet
  2. Step 2: Attach The Filter In Either Onto The End Of Your Kitchen Faucet Or Tap It Into The Cold Water Line. The filter will screw on most faucets with external threads, but those with internal threads require an adapter. Make sure the filter is screwed on level, too, then tighten by hand, not pliers, which could break it.

Step3: Finally Run The Water.

If the adapters don’t fit perfectly, don’t force it. Instead, call the manufacturer and ask for another adapter to try.


There is no telling what is coming through that faucet. Many contaminants are not detectable by taste or smell and can even escape specific diagnostic tests specifically designed to detect impurities. In any house, it’s a great idea to install any type of water filter.

Water filters can be an effective way of protecting you and your family against hidden contaminants. This is an easy and relatively cheap way to provide peace of mind. Why roll the dice and assume that it is okay because the water tastes fine and smells fine. 

It may be assumed that contaminant concentrations are low. These low concentrations are not harmful in individual doses, but with time, it is difficult to predict possible adverse effects. You can count on these water filters to keep these contaminants out of the water on which you and your family rely. You can also check out these best countertop water filters on the market and also these best water softeners if you have too much iron content in your well water.
