Your Pool / Hot Tub Deserves Spa-Daddy Brand Filters

Don't settle for less - if it doesn't say Spa-Daddy then it's not a genuine Spa-Daddy Filter. Our filters are the best pool, spa and hot tub filters available. Why? The difference is our free flow core. The core of the filter provides the structure around which the filtration material stands.


Before the water passes through the filtration material, if first must travel through the core, and that is the limiting factor of the filter. If the core is mostly plastic with a few drilled holes, the core inhibits water flow forcing the filtration material immediately around those holes to do all the filtration, providing less filtration, less water flow, and significantly shortens the life of the filter.

Our cores are engineered and molded (not drilled PVC) which allow for the even flow of water through the entire cartridge which provides these benefits:

  • Increased filtration translates to greater efficiency
  • Greater media surface inhibits the growth of bacteria mold & algae delivering the best water quality
  • Makes it easier for the pump to pull more water through the cartridge, meaing less wear & tear on your pump

In the final analysis, our Premium Spa-Daddy Brand Filter Cartridges with Free Flow Cores deliver the purest water quality and saves money! Your water pump works hard - Extend its life with the quality of Spa-Daddy brand filters.

The 3 Fundamentals of Sparkling Clean Water:

Fundamental 1 - A clean filter is a must.  Whether it is a replacement spa filter or a swimming pool filter cartridge, we have the filter to fit your need. A Clean Filter to filter all the dirt, body oils and dead bacteria from the water.  Clogged Filters don't work so you need to deep-clean or replace your filter(s) on a regular basis. We carry replacement pool and spa filters for almost every make and model of pool or spa.
Fundamental 2 - An effective sanitizer - The proper use of pool and spa chemicals can give you piece of mind while you enjoy your time in the water A Good Sanitizer to kill bacteria (you don't want a rash!).  The most commonly used sanitizers are Chlorine and Bromine, and these are often used with mineral cartridges to increase their effectiveness.
Fundamental 3 - Water Clarifier - Using an effective water clarifier such as shock will make your pool and spa water sparkling clean. An effective Clarifier.  Dirt, bacteria, flaked-off skin, body oils, makes your water dirty and cloudy. There are two types of clarifiers: 1) Shock which oxidizes these contaminants, dispersing them into the air or 2) Clarifiers which 'clumps these contaminants together', making them large enough for your filter to remove them from the water.

One of the most frustrating things for spa and hot-tub owners is keeping their spa water sparkling clean. Visit any spa-shop and you'll walk out confused by 23 different products - shock, oxidizers, bromine, chlorine, de-floccing agents, de-foaming agents, etc.  Once you're done with all that, your spa will smell like a chemical-factory.  Fortunately, we've sorted through everything and developed our 3-step simple system for clean, sparkling water.  Here's the easy way to keep your water crystal clear and trouble-free without investing a lot of time or money.

  1. Water Filtration - Make sure your filters are clean and working well

This is the most important and most frequently overlooked aspect of maintaining sparkling clean water. Your filters are the only thing which actually remove dirt, oil and other contaminants from your spa water, keeping the water crystal clear. The chemicals that you add to your water don't actually remove the dirt and oil - they just make these contaminants emulsify (or 'clump together') making them large enough to be filtered our by your filters. Over time, as your filters filter out the oil and dirt, the tiny pores in the filter material get clogged, and the filters become less effective. Over time, your water will get cloudy and dirty unless the filters are cleaned and these tiny pores are re-opened.

Most people think that cleaning a filter means rinsing it with a garden hose, but that doesn't remove the microscopic dirt which is clogging the tiny pores, and a rinsed filter won't perform any better than a dirty filter. Effective cleaning takes one day of soaking and one-two days of drying (this is critical to open the pores), so you need two sets of filters to keep your spa really clean.

  1. Water Sanitization - Kills bacteria

If you've ever been in someone's spa and developed a rash afterward, it's because there was bacteria in the water which means that the water wasn't properly sanitized. Fortunately, it's easy to keep the water sanitized - you simply make sure that your spa always has a supply of bromine, which is poisonous to bacteria. Even crystal clear water can be contaminated by invisible bacteria, so it's important to check your bromine supply whenever you are in the spa, and replenish it whenever it gets low.

  1. Water Clarification - Remove all contaminants

When you change the water in your spa, the water may look clean, but it isn't. It will contain some combination of rust, phosphorus, oil and dirt, all of which will make the water dull and cloudy over time. To have a crystal clean spa you have to start with crystal clean water, so whenever you change the water in your spa immediately treat it with our Spa-Magic cleaning formula which binds these invisible contaminants together so they can be filtered away.

Once the water is clean, the only thing you have to worry about on an ongoing basis is body oil and dirt which gets into the water when you use it. To remove the body dirt and oil you need to do is to treat the water with Shock which burns off these contaminants or use a Water Clarifier to 'emulsify' (or 'clump-together') the body oils and dirt so the filters can filter them out. Remember - these additives don't really clean the water, that's the job of your filters - your filters clean the water so if the water's getting cloudy or dull, you need to change the filter.
