Your spa filter is the hardest working component in the system. Every second the spa runs, it is trapping algae, bacteria, body oils, dead skin and hair — all while keeping your water safe to soak in. Neglecting it is the fastest way to cloudy water and expensive problems. Here is how to keep it in good shape.
When to Replace Your Filter
Replace immediately if you notice any of the following:
The filter has been in use for more than 12 months
Discolouration appears — grey, brown or green hues on the filter material
The filter looks beige or off-white even after a thorough clean
The filter element loses its fibrous texture, begins to unravel or disintegrate
Cracks or splits appear on the top or bottom of the filter housing
The spa has a new owner — always replace the filter when taking over a second-hand spa
Daily and Weekly Habits
Run on low speed for at least 3 hours daily
Good circulation keeps the water turning over through the filter even on days when the spa is not being used.
Weekly rinse with a high-pressure hose
A firm rinse through the filter pleats removes accumulated debris and keeps flow rates healthy between deep cleans.
Add Spa Shock and Water Clarifier weekly
These assist the filter in doing its job. Shock breaks down organic waste, clarifier clumps fine particles together so the filter can catch them.
Use a Scumball or Scumbug
These float in the spa and absorb body oils and residue before they reach the filter. Squeeze out after each use and replace when saturated.
Deep clean every two months
Use a Filter Cleaner Solution to remove oils and mineral buildup that a hose rinse cannot shift. Also do a deep clean whenever you drain and refill.
Check the filter is seated correctly
A filter that is even slightly off-position lets water bypass it entirely. Check the seating every time you reinstall after cleaning.
Never use soap-based cleaners on the filter or spa
Soap residue causes persistent foaming that no amount of anti-foam will permanently fix. This includes car wax on the spa shell.
Three Tips Worth Acting On
Tip 1
Keep two filters, rotate weekly
One filter runs while the other soaks in cleaner. You always have a fresh filter ready and never have to run the spa on a dirty one while you wait for the other to dry.
Tip 2
Ask users to shower first
Hair products, deodorant and skin creams go straight into the water and straight into the filter. A quick rinse before entry makes a measurable difference to how long the filter stays clean.
Tip 3
No regular clothing in the spa
Detergent and dye residue in everyday clothing clouds the water and clogs the filter fast. Proper swimwear only — rinsed in clean water before use.
A Spa is Not a Bathtub
No soaps, no oils, no bath products. If guests have long hair, keep a few swim caps or baseball caps nearby to keep products out of the water. The filter can trap a lot — but it works best when you give it as little unnecessary work as possible.
