2 AquaRest Dream Maker Hot Tub Spa Filters (Round Cartridge) Aqua Rest Twin Pack by Clarathon

Match Your Spa Filter by Size, Not Just Brand

This is a Clarathon aftermarket twin pack of round filter cartridges, part number PDM28. The Amazon listing identifies it as a replacement for 2015 and newer AquaRest spas and DreamMaker Cottage Collection models.

Verify the dimensions first

• Listed size: 5-1/2-inch diameter by 7-1/4-inch long, with a 3-inch opening on both ends.
• Measure your existing cartridge — matching diameter, length, and end openings is the surest fit check.

What you’re buying

The pack contains two filter cartridges per the listing. This is an aftermarket replacement identified by the seller as compatible with the named spa lines; it is not a genuine part from the spa manufacturer, so expect Clarathon branding on what arrives.
