Spa Filter PWL35P3 - 6TP-176BP for Wellis BlueWater Filtration® Spas
Product Information: Boospa is gradually replacing its Topology filter range with Cleonia filters, designed by us. Depending on stock availability, you may receive either model. The delivered filter may therefore differ slightly from the visual (black or blue base, neutral or Topology label), but remains strictly identical in terms of reference, dimensions, and compatibility.

Frequently Asked Questions
Is the PWL35P3 / 6TP-176BP filter compatible with my Wellis spa?
This filter is specifically designed for Wellis spas equipped with the BlueWater Filtration® system. If your current filter bears the reference PWL35P3, 6TP-176BP, or AKU0135, this product is the direct equivalent. If in doubt, check the reference on the filter in place before ordering. Use our selection guide to validate.
How to verify that the dimensions 149 mm x 176 mm match my current filter?
This filter measures 149 mm in outer diameter and 176 mm in length. Measure your current filter flat: the diameter is taken on the pleat, the length from end to end without the end caps. A few millimeters difference can prevent installation. For a step-by-step measurement, check our spa filter measurement guide.
What is the difference between the BlueWater Filtration® version and a standard Wellis filter?
The BlueWater Filtration® version incorporates an antimicrobial action in the filter media, distinguishing it from a standard replacement filter. This filter is manufactured under the Cleonia brand (formerly Topology) and sold directly by Boospa. It is sold individually: one piece per order, not in bulk.
How to properly maintain this 176 mm PWL35P3 filter to extend its lifespan?
Rinse the PWL35P3 filter with clear water weekly to remove surface deposits. A thorough cleaning with a suitable product is recommended regularly, focusing on the folds of the filter media. The dimensions 149 mm x 176 mm and the top handle facilitate handling during this operation. Find the recommended products and materials on our spa filter cleaning products page.
How often should the PWL35P3 filter be replaced on a Wellis spa?
The replacement frequency depends on spa usage and water quality. A regularly cleaned filter will last longer, but it should be replaced as soon as the filter media is deformed, persistently discolored, or when filtration becomes insufficient. Rigorous maintenance is the best way to maximize its lifespan.
Can this PWL35P3 filter be shipped the same day as my order?
If the filter is indicated as in stock on the product page, your order will be shipped the same day if placed before 1 pm. This is a concrete advantage if your spa is out of order awaiting replacement. Check availability directly on the page before confirming.
Can I return this filter if the 6TP-176BP reference does not match my spa?
A return is possible provided the filter is in its original packaging, unused, and uninstalled. It can be done within 14 days after receipt. For industry professionals, this period can be extended to 60 days. Before ordering, compare the reference of your current filter - PWL35P3, 6TP-176BP, or AKU0135 - with the one indicated on the product page. This reduces the risk of error and avoids a 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. The exact options will be displayed in your cart.
How can I track my package?
