Cleaning Spa Filters

Keeping your spa filter clean means better hot tub performance and cost savings.

Why are there cost savings? Because maintaining your hot tub water will prevent early wear of pump seals, pump union o-rings and other hot tub components that can become damaged due to poor water quality.  A pump may need to work harder to pull water through a dirty filter also causing excessive wear on the pump.

Spa Filters Canada Hot Tub Filter Cleaning Tips

Cleaning a filter is a simple as regularly washing off the filter media pleats.  Using a garden hose or a cartridge filter cleaning device, rinse the filter for several minutes and replace.



Filters should be replaced with new spa filters every year or so depending on hot tub use for optimum performance.  Buy filters in bulk and save.

Consider generic filters instead of brand name filters to save even more.  Many generic filter types use similar if not superior filter media but do not require the marketing budget that larger brand names need.  You may rely on brands such as Pleatco, Filbur or Unicel and will certainly get a good filter, but you may also save a bundle with quality generic filter brand.
