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.

Our recommendations for optimal maintenance of your 40508 / SC757 filter:
- Clean your filter at least once a month, or more frequently with intensive use.
- Replace the filter every 3 to 6 months, depending on water quality and spa usage frequency.
- Always have a spare filter on hand to avoid any interruptions in spa use.
- Follow the manufacturer's recommendations for filter maintenance and replacement.

The 40508 filter is also available in a BlueWater filtration version. The material used in making this filter has been specially treated to provide antimicrobial action. The filtration capacity is thus enhanced for superior water quality compared to a standard filter.
Frequently Asked Questions
Is the 4CH-949 filter suitable for my Hydropool or Arctic Spas spa?
If your current filter has the reference 4CH-949 (Unicel), PWW50L (Pleatco), 40508 (Darlly), or RD800-2110 (Rising Dragon), this filter is the direct equivalent. It is also compatible with Hydropool, Arctic Spas, Dynasty Spas, Sunrise Spas, and Whitewater spas, among other brands. If in doubt, first compare the reference on your current filter. Use our selection guide to validate. How to verify that the dimensions 325 mm x 127 mm match my current filter?
This filter measures 325 mm in length and 127 mm in outer diameter. Measure your current filter excluding end caps, then compare these two values. A difference of a few millimeters can prevent proper installation. To avoid mistakes, follow the measurement guide available on our spa filter measurement guide.
Can the color of the delivered filter differ from my original Topology filter?
Boospa is gradually replacing the Topology range (reference 4TP-949) with Cleonia filters. The delivered model may therefore have a slight color difference from your original filter. The dimensions remain identical - 325 mm x 127 mm - and compatibility is preserved. There is also a BlueWater version with antimicrobial treatment available if you prefer this option.
Is a specific product needed to clean this 212 pleat filter?
With 212 pleats, the filter surface area is significant and retains more residues. Regular rinsing with water extends the filter's lifespan, but a thorough cleaning with a suitable product is still necessary. Find products compatible with this type of cartridge in our dedicated selection: spa filter cleaning products.
How often should a 325 mm filter like this one be replaced?
The lifespan of a filter depends on spa usage and water quality. A filter of this size - 325 mm, 212 pleats - is typically replaced every 12 to 24 months. If the filter remains dull after cleaning, if the pressure drops, or if the water remains cloudy, it's a sign that replacement is necessary. This filter is sold individually.
If I order today, can I receive this filter quickly?
If the product is in stock, any order placed before 1 pm is shipped the same day. This filter is sold individually, without being part of a set, making ordering easier if you have only one filter housing to replace. Check availability directly on the product page before confirming.
What should I do if the PWW50L filter received does not match my spa?
A return is possible provided the filter is in its original, unused, and uninstalled packaging. It can be done within 14 days of receipt. For industry professionals, this can be extended to 60 days. Before ordering, ensure that your current filter carries one of the equivalent references: PWW50L, 4CH-949, 40508, FC-0172, or RD800-2110. This will prevent any return process.
What are the possible delivery methods?
Delivery depends on the product, your country, and your address. Depending on the order, shipping can be done to your home or to a pickup point. Exact options are displayed in your cart.
How can I track my package?
You will receive email notifications at different stages, with a tracking link or number upon shipment. You can also check in your customer account.
What payment methods are accepted?
