Product information: Boospa is gradually replacing its Topology filter range with Cleonia filters, designed by us. Depending on stock levels, you may receive either model. The delivered filter may therefore differ slightly in terms of the base color and label, but remains strictly identical in terms of reference, dimensions, and compatibility.

Frequently Asked Questions
Is filter 40353 compatible with my Sundance or Jacuzzi spa?
If your current filter bears one of the references PRB35-IN, C-4335, FC-2385, or T-4335, this filter is the direct equivalent. It is thus compatible with several brands including Sundance, Jacuzzi, Waterway, or Canadian Spas. If in doubt, first compare the reference on your used filter with those listed above. If in doubt, our selection guide can help you.
How to verify that the dimensions of this filter (235 mm x 127 mm) correspond to my installation?
This filter measures 235 mm in length by 127 mm in diameter, with two open ends of 54 mm. Measure your current filter dry before ordering. Even a small deviation in diameter can prevent correct installation in the filter housing. For guidance on taking measurements, consult our spa filter measurement guide.
What is the difference between the standard version and the BlueWater Filtration version of filter 40353?
This filter is offered in two versions with identical dimensions (235 mm x 127 mm). The standard version provides standard particle filtration. The BlueWater Filtration version incorporates antimicrobial technology in the filter media. Both versions are also available in a pack of 2. Choose the antimicrobial version if you want enhanced filtration against microorganisms.
Do I need a specific product to clean this filter with two open ends?
The two open ends of this filter facilitate rinsing, but regular cleaning with a suitable product is essential to preserve its performance. A standard cartridge cleaner is suitable, supplemented if possible by periodic descaling. Discover the spa filter cleaning products.
How often should this 235 mm filter manufactured by Boospa be replaced?
The lifespan of a filter depends on usage, water quality, and regular cleaning. A well-maintained filter typically lasts one to two seasons. Watch for signs of wear: deformed pleats, discolored media, or loss of pressure. Since this filter is sold individually, you can replace it yourself or opt directly for the pack of 2 to anticipate the next replacement.
Can I receive this filter quickly if I order today?
If this filter is in stock, your order will be shipped the same day if placed before 1 pm. This is particularly useful if your spa is currently out of service awaiting filter replacement. Check availability directly on the product page before confirming your order.
What if filter 40353 ultimately does not fit my filter housing?
If the filter is kept in its original unopened packaging, it can be returned. Therefore, it is important to check the dimensions (235 mm x 127 mm) and equivalent references before any installation. If you have doubts before opening the package, compare the reference of your old filter with the PRB35-IN, C-4335, FC-2385, or T-4335 codes indicated on this product. It is possible within 14 days after receipt. For industry professionals, it can be extended to 60 days.
