5 Ways to Improve Your Spa Filtration

Is your spa filter too small? Improving your spa filtration system can make your water cleaner, clearer, safer, and easier to manage with fewer chemicals. Here are five effective ways to improve your spa or hot tub filtration.

Upgrade to Spa Filters with More Square Footage

Upgrading to a spa filter with more square footage can significantly improve your spa filtration. For example, the HTF-2370 and HTF-2390 filters have the same dimensions, but the latter offers 50 square feet of filter surface area compared to the former's 25 square feet. This increase is achieved by adding more pleats to the cartridge, effectively doubling the surface area. While spa filters with more square footage are more expensive, they provide longer filter cycles and better overall filtration, making them a worthwhile investment.

Clean Your Spa Cartridge with Filter Cleaner

Another way to improve your spa filtration is by cleaning your spa cartridge. Cleaning your spa filter cartridge is crucial for maintaining optimal filtration. Use a garden hose to flush out dirt and debris from between the pleats. For a more thorough clean, use a filter cleaner. Soak the cartridge in a bucket of water mixed with the recommended amount of filter cleaner for the specified time, then hose it clean. Filter cleaners loosen mineral deposits, dirt, and oils, making cleaning more effective.

Replace Your Spa Cartridge on Schedule

Regularly replacing your spa cartridge is essential for maintaining filtration efficiency. Generally, cartridges should be replaced every 12-24 months, depending on usage and cleaning frequency. Over time, the fibers in the cartridge loosen, allowing particles to bypass the filter. A good rule of thumb is to replace the cartridge after 12-15 cleanings to ensure your spa water remains clean and clear.

Drain Your Spa on Schedule

Draining your spa every 3-6 months is another important maintenance task. The frequency depends on how often you use the spa, the size of the spa, and the overall water quality. Over time, total dissolved solids can build up, affecting water balance. Draining the spa also allows you to use a biofilm remover, like Jet Clean, to clean the pipes and hoses of bacteria, and a cleaner like Citrabright to polish up the spa.

Use Enzymes or Clarifiers

Adding spa enzymes or clarifiers can further enhance your filtration system. Spa enzymes digest body oils, makeup, soaps, and other substances, reducing sanitizer demand and increasing filter cycles. These enzymes are effective in managing your spa’s oil problem. Spa clarifiers coagulate small particles into larger clumps that are easier to filter, improving overall water clarity.

Pro Tip: Some spas and hot tubs have undersized cartridge filters. If you can't upgrade to a larger filter, using the tips above can help improve filtration and compensate for any inadequacies without resorting to heavy doses of sanitizer.

By following these expert tips, you can improve your spa filtration and ensure your spa or hot tub remains a haven of clean, clear, and safe water.
