    The Right Filter for Every Model

    Don't risk using a generic filter that doesn't fit. We specialize in authentic replacements for specific years and models, ensuring optimal filtration and flow for your spa.

    Our Best-Selling Filters

    Pre-2014 Models (PDM25)

    If you have an older Aquarest or Dreammaker model manufactured in 2014 or earlier, the PDM25 Pleatco Filter is your perfect match. Restore your spa's performance with this essential replacement.

    2015+ Models (PDM28)

    For spas manufactured after 2015, the PDM28 offers superior filtration. Designed to fit seamlessly into newer housings, it traps debris efficiently so you can soak in cleaner water.

    Daydream 3500 Series (2023+ Oval) ( PDM-30)

    Owners of the latest Daydream 3500 series need the specialized 30 sqft oval filter cartridge. We carry these hard-to-find 2023+ filters to keep your modern spa running like new.

    Frequently Asked Questions

    How often should I change my hot tub filter?

    For optimal performance and hygiene, we recommend rinsing your filter weekly and replacing it every 12 months, or sooner if the media becomes frayed or clogged.

    Will these filters fit brands other than Aquarest?

    While these are the standard for Aquarest and Dreammaker, they are also used in select other tubs. Check your current filter's part number—if it matches PDM25, PDM28, or the 30 sqft oval specs, these are the right choice.

    How do I know which filter I need?

    The easiest way is to check the year your tub was manufactured. Generally, 2014 and older use PDM25, while 2015 and newer use PDM28. For 2023 Daydream models, look for the oval shape.
