Frequently Asked Questions
Is the 4CH-949 filter suitable for my Hydropool or Arctic Spas?
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 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 compared to your original filter. The dimensions remain identical - 325 mm x 127 mm - and compatibility is preserved. There is also a BlueWater version with anti-microbial treatment if you prefer this option.
Is a specific product needed 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 products compatible with this type of cartridge in our dedicated selection: spa filter cleaning products.
How often should a 325 mm filter like this 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, the pressure drops, or the water remains cloudy, it's a sign that replacement is necessary. 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, making the ordering process simpler if you have only one filter housing to replace. Check availability directly on the product page before confirming.
What to do if the received PWW50L filter 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 after 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 from 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 relay point. The exact options are displayed in your cart.
How to track my package?
You will receive email notifications at different stages, with a tracking link or number upon shipment. You can also check your customer account.
What payment methods are accepted?
Payment is possible by credit card, PayPal, 4X PayPal, bank transfer, or check. For a bank transfer, shipping occurs after receipt of funds.
