For busy dog owners, pet fountains are great in how they help to save time and energy. They're also beneficial for dogs who often forget to drink enough water. Automatic water fountains for dogs not only provide fresh water, but also filter out impurities. If you've got one of those automatic pet fountains for your dog, you're going to need the best pet fountain replacement filters.

Top Best Pet Fountain Replacement FiltersMost dog owners believe that their pet will drink enough water throughout the day all on his own. Unfortunately, this isn't the case, yet proper hydration is important to maintain your dog's overall health and well-being. Just like ours, the canine body is largely comprised of water. Hydration helps to maintain healthy organs, tissues and supporting dog's blood circulation.

Dogs do not enjoy drinking warm, stagnant water. Would you? If the only water available has been in a bowl on the floor for the last few days without being refreshed, your dog will likely pass on drinking it even if he's thirsty.

Then Fido will start to look for new sources of water. Puddles, ponds, pools and other unsafe sources may be the next place your pup looks looks to drink from and risk water intoxication. If the dog can't find another source of water, he may just go without drinking at all if the provided H2O doesn't entice him, risking dehydration.

Automatic dog water bowls and pet fountains provide a constantly circling cold water for dogs, and they have filters that remove impurities from that water . Over time, these pet fountain filters become dirty and need to be changed. So here's a quick look at the best pet fountain replacement filters we'll be discussing in this article:

Pet Fountain Replacement Filter Brands Price Quality Rating

PetStandard Premium Charcoal Filters for Fountains $$ A 4.5/5
Pioneer Pet Replacement Filters for Fountains $$ B 4.6/5

Dehydration in dogs and not drinking enough water at home

Dehydration in dogs and not drinking enough water at homeA lot of dog owners don't realize that their pets can become dehydrated just as easily as we can. The problem is that dogs may not be aware of the signs of dehydration. Yet it is a very serious and, unfortunately, common problem that poses serious health risks for dogs and that vets often encounter.

The result is damage to your dog's vital organs – his kidneys, livers and heart in particular – that could be fatal. It's not that unusual to forget to replenish a dog's water bowl, but it could have disastrous consequences.

To understand dehydration in dogs better (and how to prevent it), I recommend you take a look at this science-based document (PDF). They explain why dogs go without drinking for long periods of time and how you can prevent dehydration in your dog.

Pet water fountains for dogs are a great way to entice your pooch to drink enough liquids, but you need to be sure the fountain filter is clean. If not, bacteria and debris could continue to circulate through the water. By regularly switching the old filter out with one of the best pet fountain replacement filters, you'll ensure Fido's water is clean and fresh.

1 PetSafe Drinkwell Premium Carbon Filters

PetSafe Drinkwell Premium Replacement Carbon Filters, Dog and Cat Water Fountain Filters, 3 Pack, Black and White

Filtration makes water clean, fresh and safe to drink. It also helps extend the lifespan of your fountain and pump. PetSafe replacement filters provide total water purification using duo-density polyester pads. The pad traps fur, fine debris, and sediments invisible to the naked eye, while the carbon layer removes chlorine, odors and bad tastes to ensure fresh water at all times. These replacement filters are available in packs of 3, 6 and 9, with each pad segmented into 6 compartments for more effective filtration.

The PetSafe Drinkwell Premium Carbon Replacement Filters are compatible with PetSafe Drinkwell Original, Big Dog, Everflow, Mini, Multi-Tier, Outdoor Dog, Platinum and Zen pet fountains. These filters must have really improved the water’s quality and appeal because pet owners observed their pets drinking more often than usual. This has been especially advantageous for pets that needed proper hydration, such as those with urinary tract and kidney issues.

PetSafe Drinkwell Premium Replacement Carbon Filters, Dog and Cat Water Fountain Filters, 3 Pack, Black and White

The reason for this quality could be from the materials used, which are coconut shells. PetSafe uses them because they’re 50% more carbon-packed than most brands, they absorb more contaminants than the average filter. For 3-4 weeks, the filters will do the work of ensuring clean and good-tasting water, after which they’d have to be replaced and the fountain cleaned for proper maintenance.

PROS:

  • Available in packs of 3, 6 or 9
  • Made with coconut shells because of their high carbon content
  • Each of these best pet fountain replacement filters lasts for 3-4 weeks
CONS:

  • Some reviewers complained that these filters left loose carbon particles in the water
  • Some reviews state that these filters don't fit their fountain, even though the product description says that they should

2 PetStandard Premium Charcoal Filters for PetSafe Drinkwell Fountains

Premium Charcoal Filters for PetSafe Drinkwell Fountains, Pack of 10

The Premium Charcoal Filters from PetStandard come in a well-priced pack of 10 filters giving it an economical advantage over other brands. They’re perfectly safe to use and fit well with all models of PetSafe Drinkwell pet water fountains. The filter is made up of two filtration layers. The lighter side is a high-density polyester filter, while the darker side is a charcoal filter. The polyester filter traps hair, debris, and physical impurities. The charcoal filter absorbs nasty smells and taste, and helps eliminate chemical compounds usually found in water.

What’s more, each pad is equally divided into 6 compartments for an even distribution of charcoal. This prevents charcoal powder from settling at the bottom of the filter. Unlike pet bowls that need to be cleaned every 2-3 days, the pet fountain can take a full 4-week stretch before it really needs cleaning. It does need an efficient filter to maintain water quality within that period, and pet owners attest to the high quality of PetStandard Premium Charcoal Filters for PetSafe Drinkwell Fountains.

Premium Charcoal Filters for PetSafe Drinkwell Fountains, Pack of 10

Most users prefer replacing the filters monthly which often coincides with the monthly cleaning of the water fountain. Households with numerous pets, though, may need to change the filter at least twice a month. The 10-pad filter pack is a steal of a deal, too, say pet owners. A pack actually lasts several months even for those who need to change filters as often as twice monthly, and pet owners simply can’t resist buying these economical and convenient replacement filters.

PROS:

  • Two layers include one side made of a high-density polyester filter and the other is a charcoal filter
  • Each filter is divided into 6 compartments to prevent charcoal settling at the bottom of the filter
  • These best pet fountain replacement filters only need to be changed about every 4 weeks
CONS:

Pet owners attest to the water-cleansing quality of Pioneer Pet Replacement Filters for Ceramic and Stainless Steel Pet Fountains in promoting good health in their pets.

Others who clean their fountains weekly simply wash the filters through running water and only replace them after several repeat uses. This way, they report having extended the life of the filter up to 4-6 weeks.

Some finicky pet owners found it really efficient when they replace the charcoal in the filter cartridge with activated charcoal as often as every week.

By regularly changing the whole filter using these replacements is a lot simpler.

PROS:

  • 3-layer filtration filtration system
  • Measures 3/4-in x 4-in x 2 ½-in
