When you use your spa the filter absorbs all of the body oils and debris that are left behind when you exit the spa. Over time the filter can become dirty and clogged, causing your pump to work harder and reduce the water circulation. After approximately 4-6 months of usage your filter should be replaced with a new one to keep your spa running in pristine shape. Unfortunately, there are hundreds of filter types on the market, but here are a few tips to determine which filter you have.
- Check the spa manual to see if the filter model is identified. Currently, there are three big filter manufacturers on the market: FILBUR, PLEATCO, and UNICEL. These three manufacturers each have their own unique model numbers that sometimes make it difficult to determine which filter you have. Luckily these filters are interchangeable, so a UNICEL#: 6CH-940 can be replaced with a PLEATCO#: PWW 50. At the Canadian Spa Company we try to keep our filters standard to make it a very simple task for you to replace them.
- Without a model number, specific measurements may need to be made to make an accurate replacement. Measure and record the outside diameter (A), the length of the filter (B), and the inside diameter (C). NOTE: When measuring the length, a more accurate measurement is made by measuring through the centre of the filter (if possible).

- Contact your manufacturer for information regarding filter replacement. Most of the time a manufacturer will upgrade the previous version of your spa and may change the filter size. This will result in ordering the wrong filter for spa. A simple email explaining your question can help save you time and money.
Be sure to check your filter often in case it needs to be replaced. Prolonged use of a dirty/clogged filter can cause long lasting damage to your spa equipment and create problems over time. A simple check whenever you leave your tub should be sufficient to prevent any filter problems that may occur.
