Product information: Boospa is gradually replacing its Topology filter range with the Cleonia filters, designed in-house. Depending on stock availability, 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 this filter suitable for my Caldera spa?
Yes, this filter is designed for Caldera Spas. If your current filter has one of the references 81004, C-8399, T-8399, FC-3085, or PCD100W, this model is a direct equivalent. Simply check the reference on your used filter before ordering. If in doubt,our selection guide can help confirm the correct model. How can I verify that the dimensions 418 mm x 200 mm match my current filter?
This filter measures 418 mm in length and 200 mm in diameter. To confirm compatibility, measure your used filter without the gasket: the length is taken from one end to the other of the cylinder, and the diameter is measured halfway up. A few millimeters difference due to gaskets is normal. Refer to our spa filter measurement guide to avoid mistakes.
Do I need a specific product to clean this Caldera filter?
Rinsing regularly with water extends the cartridge's lifespan. For deep cleaning, a specific spa filter product helps remove grease and embedded residues in the pleats. Find our selection of filter cleaning products suitable for this type of cartridge. How often should I replace this 418 mm filter on my Caldera spa?
The cartridge's lifespan depends on spa usage frequency, water quality, and regular cleaning. Generally, a regularly cleaned filter lasts between 12 and 24 months. Monitor the pleats' condition: if they are deformed, discolored, or if filtration decreases despite cleaning, it's time to replace the cartridge.
Can this high-handle, open-bottom filter be installed without any special tools?
This filter is designed with a handle at the top and an open bottom end (92 mm). This type of configuration can be installed and removed by hand, without screwing or specific tools. Just make sure that the open bottom of your filter housing matches this format before proceeding with the replacement.
If my Caldera spa is experiencing filtration issues, can I receive this filter quickly?
If the product is in stock, any order placed before 1 pm is shipped the same day. Check the availability displayed on the product page when placing your order to confirm.
What if the 81004 filter doesn't match my setup once received?
A return is possible provided the filter is in its original packaging, unused, and not installed. It can be done within 14 days of receipt. For industry professionals, this can be extended to 60 days. Before ordering, check the reference on your current filter and compare the dimensions (418 mm x 200 mm) to minimize this risk. If unsure about compatibility, contact us before confirming your order.
