Not sure which filter your Master Spas takes? Many models use a two-part system — a pleated outer filter with an EcoPur Charge mineral core — and some add a stand-alone filter in its own housing. Send us a photo of your filter or your serial number and we will confirm before you order.
Looking for a lower-cost option? The same size filter (40 sq ft, 6″ diameter, 2″ male fine thread) is available as a ProAqua high-flow replacement for Master Spas, or go reusable with the Ego3 #3 refillable cartridge — refill the media instead of buying a new filter.

Did you know the number one reason for hot tub freeze damage is a dirty filter? Dirty filters also cause additional stress on the pump/motor and leads to premature failure.
Proper Filter Care System:
- Have 2 sets of filters
- Install clean filter
- Rinse dirty filter with high pressure nozzle
- Verify no debris left between pleats, before storing on shelf to dry
- Once a month soak filters in a filter cleaner solution

✅ Not Sure It Fits? Verify Before Ordering
Hot tub part compatibility can vary by spa brand, model, year, serial number, control system, and part revision.

It fits the Master Spas Twilight Series models listed above (2009-2024). Master Spas changed filters across model years, so check your model and year — or use the fitment form above with a photo of your filter or serial number sticker.
This is Master Spas X268543, PMA40L-F2M (Pleatco), replaces X268365 (older antimicrobial version) and PMA40L.
Yes — this is the OEM Master Spas part (made for Master Spas by Pleatco), not an aftermarket copy.
Master Spas recommends replacing the pleated filters at least once a year and the EcoPur Charge mineral core every 6 months. Rinse pleated filters every 2–4 weeks and soak them monthly in filter cleaner.
A spare set means you always have a clean, dry filter ready while the other soaks, and multi-packs cost less per filter than singles.
It ships from our supplier warehouse, typically within 1–2 business days.
