4 Pouch FM4P-G Replacement Filter for Hot Tub/Spa & Above Ground Pools, Standard Cartridges 15"-18" Tall, Yellow

Filter Minion Miracle Balls are the new and better mousetrap in the hot tub/spa and pool filter industry. Developed with German technology in 2012, each of the 16 fibrous balls in their mesh pouch are charged with a patented Silver Ion process that traps and restricts growth of what is called biofilm, which is the yucky stuff we see and smell in the water we'd prefer to be relaxing in. These miracle balls trap finer particles down to 8 microns, which means that your water will be cleaner than you're used to, and also because every drop of water passes through the balls instead of going down the center hole of a standard cartridge, and hopefully getting filtered on the next cycle. Cleaning the pouches is far easier than cleaning the pleats in a standard cartridge where the hose jet often throws yucky water right back on you. Just lay out the pouches on a deck, lawn, concrete or a bucket, and spray away, flipping the pouch over once or twice. It’s hard to say what the best part is about these miracle balls, but the fact that they should last you 3-5 years depending on use, which if you run the math, saves you a lot of money. Its also possible that you'll be able to use less chemicals than normal, but that will depend again on your usage levels. Take your time to see our size chart image, and read more information down below for those who want to know more.

• 4 pouches are made to replace cartridges 15"-18" inches tall
• Don't worry about what cartridge is compatible to yours, these replace most standard cartridges of any size, but see all images and size chart to match your need
• Simple install, pull out your dirty cartridge, drop pouches back in, and off you go for 3-5 years depending on use, and rinse clean just 1-3 times a year.
• Compatible with any standard cartridge 4-8” diameter & 6” to 20” tall but your cartridge must be captive in its cylindrical filter housing chamber, not free standing in the open. If your cartridge drops or threads into a cylindrical housing just larger than your cartridge, then our filters are perfect. See all images
• FILTER MINIONS outperform standard cartridges in two critical functions. Densely woven fibers filter microscopic particles that cartridges miss. Filter Minions also filter more water faster because of the larger surface area of the pouches. Save money and time in the short and long run.
• Care instructions: Wash with hose when dirty, then place back in filter hub.
