Arctic Spas Filters
Arctic Spas use the Teleweir-style cartridge that threads in from inside its bottom, in two versions of the same 5″ × 13″ size: the 50 sq ft EZ05 or the 25 sq ft EZ29 with fewer pleats. Both fit the same well — the 50 simply filters more between cleanings.
Find your Arctic Spas filter in 10 seconds
The 50 sq ft is stocked in Hurricane (USA-made) and ships the same or next business day; it is also offered in ProAqua, ProAqua antimicrobial and Darlly. The 25 drop-ships in ProAqua or Darlly. Send a photo through the form below if your cartridge threads on the outside instead.

✅ Not Sure It Fits? Verify Before Ordering
Hot tub filter fitment varies by spa brand, model, year, filter size, thread style and top/bottom style.
To confirm the correct replacement, send clear photos of:
- The label or end cap of your current filter
- Your spa serial number sticker
- The filter well with the filter removed (so we can see the fitting)
EZ Hot Tub Parts confirms fitment before you order, so you do not pay return freight on a wrong filter.
Arctic Spas filter buying guide
50 sq ft, EZ05. 5″ across, 13″ long, closed handle top, 1-1/2″ female SAE thread inside the bottom (Pleatco PWW50L, Unicel 4CH-949, Filbur FC-0172). Stocked here in Hurricane, made in the USA; ProAqua, ProAqua antimicrobial and Darlly drop-ship.
25 sq ft, EZ29. Same dimensions and thread, lighter pleat pack (Pleatco PWW25L, Unicel 4CH-926, Filbur FC-0171) — ProAqua / Darlly. Use it if your spa shipped with the 25 and you prefer the original flow rate, or step up to the 50.

Arctic Spas filter questions
