Is the 4CH-949 filter suitable for my Hydropool or Arctic Spas spa?
If your current filter bears 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, among other brands. If in doubt, first compare the reference on your current filter. Use our selection guide to validate.
How can I 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 the 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 the same - 325 mm x 127 mm - and compatibility is preserved. There is also a BlueWater version with antimicrobial treatment if you prefer this option.
Is a specific product required to clean this 212 pleat filter?
With 212 pleats, the filter 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 compatible products for 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 between 12 and 24 months. If the filter remains dull after cleaning, the pressure drops, or the water stays cloudy, it's a sign that replacement is needed. This filter is sold individually.
Can I receive this filter quickly if I order today?
If the product is in stock, any order placed before 1 pm is shipped the same day. This filter is sold individually, without packaging in bulk, which simplifies the order if you have a single 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 period can be extended to 60 days. Before ordering, make sure your current filter bears one of the equivalent references: PWW50L, 4CH-949, 40508, FC-0172, or RD800-2110. This will save you the hassle of a return process.
