When we think of water fountains, we usually don’t include water fountain filters because we assume the water magically stays clean.

However, a conscious effort needs to be made on our parts as fountain users, to ensure we have access to clean water at all times, as the major function of these fountains is to provide drinking water to people.

Every year, thousands of people suffer from waterborne diseases like diarrhea, cholera, and typhoid, hence a look at the health prospects of water fountains is necessary.

In water fountains, the drinking water completes its cycle to go back into the fountain and may get dirty during this process.

This Elkay 51300C_3PK WaterSentry Plus Replacement Filter carries the benefits, of all the Elkay water filters.

The filter is made up of activated carbon, which helps in combating the odor and improves the taste of the water.

The activated carbon traps the impurities, waterborne particles, and even traces of metals like lead, through chemical adsorption in its carbon bed structure.

It’s generally advised, that you replace the filter after one year of its installation or after 3,000 gallons of use.

The water fountain filter also shows a reading of red light, which indicates the fountain needs to replace the filter kit, with a new one.

When a new filter is installed, the drinking fountain automatically sets the reading to green light after reading the RFID sensor, on the Elkay filter kit.

This Elkay filter is easy to use, in terms of removal and installation in water fountains.

Pioneer Ceramic and Stainless steel drinking fountains, allow for easy cleaning of the surfaces.

The raindrop style fountain can adorn rooms with its unique style and also attract your pets.

Pioneer Pet Replacement Filters work for all the pet fountains, mentioned above.

They contain granulated carbon filters, that are effective in removing the unpleasant smell and chemicals like chlorine and hydrogen sulfide (which gives rotten eggs smell).

Granulated carbon filters increase the surface area of the carbon filter and this allows efficient filtration of the particles and chemicals.

These types of carbon filters are also called charcoal filters.

Pioneer carbon filters contain a 3 layer filtration system.

The purpose of a multi-layer filtration system is so that, the water passes through several stages of filtration, where each stage performs a specific function to clean the water.

This improves the overall fineness of the quality of water.

Another specification about their filters is, that they have duo-density polyester pads.

As we all know, dogs and cats shed a fixed amount of hair every day, so this type of pad traps large particles in the water, like hair and debris.

So, if you’re looking for filters that can keep your stylish Pioneer raindrop or stainless steel fountains clean and healthy, these charcoal filters are the ones to go.

6. Catit Triple Action Cat Water Fountain Filter

Catit Triple Action Water Fountain Filters, Replacement Cat Drinking Fountain Filters, 5 Pack

The pack comes with a set of 2 or 5 filters, that you can use with any of the Catit water fountain models.

A study showed, that pets who drink hard water, are more likely to suffer from urinary tract infections, than those who don’t.

7. JADA Lifestyles Premium Charcoal Filters

Haustiere Premium Charcoal Filters 360 & Stainless Steel Fountains (Pack of 6) Y

If you’re looking for a cheaper option for your pet’s fountain filter, then you may need to consider JADA charcoal filters.

These filters design is a little different from the others.

Their shape resembles a bottle but the reason behind this design is, to ensure that the product remains safe throughout usage.

The packed bottle-like filters are sealed in a way, that they maintain their hygiene and can be used for longer periods, without any damage.

Let me explain with an analogy here.

If a racing car wants to perform its best, its parts need to be of high quality and contribute equally to the car driving.

Similarly, the quality of the fountain filter can also predict the life of the fountain, itself.

JADA charcoal filters claim to extend the working of the fountain because of their filter’s secure packaging and sanitary maintenance.

This filter is compatible with Drinkwell 360 drinking fountains, for cats and dogs.

Their filtration system utilizes charcoal filter beds, that are known to thoroughly clean water from any harmful chemicals, organic compounds, and unwanted odors.

Their filters are composed of PP cotton and micromesh material, for making the drinking water safe for your pets.

PP cotton stands for polypropylene cotton and is widely used in the first stage of water filtration these days.
