This is also a great place to buy tablet cleaners for your hot tub that can be used with many different types of spas.

History: Unlike any of the other companies on this list, the Jacuzzi company actually did not get its start working with hot tubs at all. The company was originally founded by a group of seven brothers who aptly called their company Jacuzzi and Brothers. They produced wooden military-grade airplane propellers and were based out of California. At one time they even made their own aircraft, although it was a short-lived project that never went very far. The company looked as though it was going to be relegated only to propellers, but in the 1950s, one of the Jacuzzi family members had the idea to use those propellers to help move water to create a hydrotherapy pump. The product was moderately successful, particularly with hospitals looking to treat patients with sore and stiff joints. By the 1970s, the family had further developed this product to be used in bathtubs in the home, and they were well on their way to manufacturing and selling the whirlpool tubs that are so widely known around the world today.

2. Hayward

In Business Since: 1915

When You’re Looking For: Cleaning canisters, filter nozzles, filter hoses, pipes

The Tork company focuses more on the smaller working pieces that make up much of the hot tub’s functionality. This is a great company from which to purchase timers, plugs, and gauges to measure temperature, pressure, and other settings in your spa. Although many of these items are intended for use with the whole hot tub and aren’t specifically made for the filter itself, some of the plugs and other accessories are necessary pieces to the hot tub filter.

4. Unicel

In Business Since: 1956

When You’re Looking For: Traditional filter cartridges, replacement filter covers

The Unicel company has been supplying affordable traditional filter cartridges for a long time and continues to supply quality products at a greatly reduced price from some of the more well-known name brands. This company focuses largely on filter cartridges and doesn’t offer many other products, but they do make many different types of cartridges in a wide variety of sizes and shapes to work with just about any hot tub on the market today, as well as several of the older models that might still be around. You can also find filter housing unit covers and guards from Unicel.

History: When it comes to longevity in the world of hot tub filters, nothing beats Unicel. This company was founded in the 1950s and originally focused only on one type of filter, which was intended for use in pools. It took less than ten years for the company’s popularity to lead it to double in size, and soon enough, more filter options were made available. As cartridge filters became more and more popular, the Unicel company was required to change its format a little bit in order to keep up with the times. They did so with flying colors, and they soon helped produce the first polyester version of the cartridge filter, which was much stronger than the paper filters that had dominated the market for the few years prior. As pools and spas slowly became more popular and more common in the average household, the Unicel company continued to create and innovate new products and methods of filtration to help keep the water as clean as possible in these products. Today, Unicel supplies replacement cartridges both o the public and via wholesale to retailers, vendors and suppliers around the world. They also are responsible for supplying maintenance and repair technicians with replacement parts for almost all of the most popular hot tub varieties available on the market today.

In Business Since: 1996

When You’re Looking For: Filter cartridge replacements, filter cleaning solution

Filbur is very similar to Unicel but does offer a few different products if you’re looking for something you can’t find through Unicel. Filbur focuses largely on filter cartridge replacements as well, and specifically the traditional paper and polyester version of these filters. You can find these filter replacements in a variety of different sizes and types, and there are also a few microfilters available from this company as well. Filbur is also a good company from which to purchase a specialized filter cleaning solution if you prefer to buy a name brand version of this instead of making it yourself at home. Filbur products do tend to be more expensive than Unicel by a bit.

History: Like many spa and pool manufacturing companies, Filbur began in California where the customer base was large. The company began by specializing in just about every type of pool and spa parts and equipment necessary to operate effectively but soon narrowed down its focus considerably to pleated filters. Filbur began making custom sized spa filters soon after its inception and the company has never looked back since. It remains one of the most well-known and highest-grossing hot tub filter supply companies around the world, and particularly in the United States. The company now offers over seven hundred different types of filters to make it easier than ever to find exactly what you need for your spa, pool, or any other water product.

History: The Aqua Klean company began as a pool installation company that soon added spas to its lineup. Although the company began in California, it soon spread to other surrounding states and enjoyed some success continuing to provide local area residents with quality products. Over time, the company continued to grow and soon branched into providing replacement cartridge filters along with its pools and spas. Now the Aqua Klean company focuses almost primarily on selling filter cartridge replacements that are made to work with almost every type of hot tub on the market today. These cartridges are often made from paper instead of polyester or ceramic, but this change in filter media material makes it easier to keep costs as low as possible when supplying customers with affordable products that work. Today, much of the Aqua Klean company’s sales come from online purchases, and this company enjoys a healthy customer base through Amazon as well as other online marketplaces. These products can also be found in many pool and spa supply stores, as well as big box retailers that provide these types of products.

8. Sundance Spas

In Business Since: 1979

The Sundance company offers a wide variety of different pieces you might need to make your hot tub experience that much better. When you shop with Sundance, you can replace your filter cartridge easily whether you have a traditional paper or polyester style filter or you want to make an upgrade to ceramic filters instead. You can also find nozzles, o-rings, washers, and jet replacements, along with light replacements and many other pieces you might find yourself needing over time.

For the decades since its creation, Sundance has continued to improve on the hot tub design to create the most aesthetically pleasing and physically comfortable spas available. Now they are sold in sixty countries around the world and remain a very popular choice for people in the United States as well.

With so many different companies working in the world of hot tubs, you can see why it’s so easy to find just what you need from a quality manufacturer you can trust. Whether you are looking for name brand products or the best way to save money on purchases that might not fall into these more popular brands, you can find exactly what you’re looking for when you shop with the companies listed above. Best of all, since they’ve all been around for at least ten years—and some much, much longer than that—you can expect a level of customer service that is sure to keep you coming back for more.

Remember that Jacuzzi isn’t the only supplier of hot tub parts on the market today, but that they do still represent one of the best options for many spa parts. If you have a Jacuzzi brand spa, you don’t have to buy Jacuzzi brand products, but you can increase the lifespan of your hot tub significantly if you do. On the other hand, if you don’t have a Jacuzzi brand spa, you might be surprised by how many Jacuzzi brand products you can use interchangeably with your spa to make it work better than ever before. Remember, however, that going with a popular brand name will cost you more than buying items from a lesser-known company, so in the end, the choice is up to you.

Whichever company or companies you plan to work with, remember to keep up with your hot tub maintenance and repair regularly, and always call a maintenance technician if you don’t feel comfortable completing a repair on your own.
