About the Filter Fitment Guide
A spa filter is the single hardest-working part of your hot tub. Every time water circulates, the filter pulls out body oils, lotions, dead skin, hair, and microscopic debris that would otherwise cloud your water, gunk up your jets, and force you to dump and refill the tub more often. A good filter, properly maintained, is what separates a hot tub that's a joy to own from one that becomes a chemistry chore.
The challenge is finding the right replacement. Hot tub manufacturers each use their own filter specifications, and within a single brand, the part numbers change every few model years. A 2018 Hot Spring Grandee uses a different filter than a 2008 model. A Sundance 880 Series uses a different filter than the 680 Series. And to make it more complicated, the same physical filter is often sold under multiple part numbers depending on whether it's an OEM (original equipment manufacturer) cartridge or an aftermarket equivalent from a company like Unicel.
This guide makes the match straightforward. We've compiled OEM and Unicel cross-reference fitment data for every major hot tub brand we sell — Hot Spring, Caldera, Sundance, Bullfrog, Freeflow, and Endless Pools — plus Unicel aftermarket filters for nearly every spa on the market. To find your filter, scroll to your brand below, locate your hot tub's model name in the fitment listings, and confirm the year range matches your spa. Click the filter name to add it to your cart.
A quick note on OEM vs. Unicel filters. OEM filters are the cartridges your hot tub manufacturer specifies — same brand, same exact specifications. Unicel filters are aftermarket cartridges built to identical dimensions and micron ratings as the OEM equivalent, typically at a lower price. Both work equally well in the vast majority of spas. Unicel is the largest aftermarket spa filter manufacturer in North America and has been the trusted alternative for decades. We list both on this page so you can choose what makes sense for your budget — most of our repeat customers split their preference about 50/50 between OEM and Unicel.
If your hot tub brand or model isn't listed here, contact us at hello@leisuretimeinc.com or call (208) 523-4633 with your spa's brand, model, year, and serial number. Our service team has access to manufacturer parts databases beyond what's on this page and can usually source the right filter even for spas we don't normally carry — Jacuzzi, Marquis, Master Spas, Cal Spas, and many more.
Search Your Hot Tub Model
Search the model of your hot tub to see if we carry the filter you need. Some filter manufacturers list filter compatibility by the entire series, so you may need to search by series title.

Hot Tub Filter Fitment Guide FAQ
How often should I replace my hot tub filter?
Most spa filter cartridges should be replaced every 12 to 18 months under normal residential use. Heavy use — multiple users daily, frequent parties, or pets in the tub — can shorten that to 6 to 9 months. Light use — once or twice a week — can extend it closer to 24 months. The clearest signs it's time to replace are visible flattening or matting of the filter pleats, persistent cloudy water even with balanced chemistry, reduced jet pressure, and longer heating cycles. If your filter looks gray or brown even after a deep clean, the fibers have absorbed too much oil and contamination to filter effectively.
How do I find which filter fits my hot tub?
You need three pieces of information: your hot tub brand, the model name, and the year it was manufactured. This information is on the serial number plate, usually located on the side of the hot tub cabinet near the equipment access panel. Once you have those details, find your brand section in the guide above and look for the filter listing that includes your model and year in its fitment range. If your spa is more than 15 years old, also note that some older filters have been discontinued and replaced with updated equivalents — contact us if you can't find an exact match and we can identify the current replacement.
What's the difference between an OEM filter and a Unicel filter?
OEM (Original Equipment Manufacturer) filters are made by the same company that built your hot tub, or licensed and branded by them. Unicel filters are aftermarket equivalents — built to the same dimensions, micron rating, and flow specifications as the OEM filter, but manufactured independently. In practical terms, a properly cross-referenced Unicel filter performs identically to the OEM equivalent. The differences are price (Unicel is typically 20-40% less expensive) and warranty implications (some hot tub manufacturers technically require OEM filters during the warranty period, though most don't enforce this in practice). For older spas no longer under warranty, Unicel is the smart financial choice. For new spas, OEM filters are the safer bet.
Can I clean and reuse my filter instead of replacing it?
Yes — and you should, between replacements. A properly maintained filter that gets cleaned monthly will last much longer than one that's left to accumulate buildup. Best practice is to rinse the filter weekly under a hose to remove surface debris, do a deeper chemical soak every 4-6 weeks using a dedicated filter cleaner, and replace the cartridge entirely every 12-18 months. Important: never clean a filter with household dish soap, laundry detergent, or bleach — these leave residues that cause excessive foaming and water chemistry problems for weeks afterward. Use only filter-specific cleaners designed for spa use.
Why is my water still cloudy after replacing the filter?
A new filter is one of several variables affecting water clarity, but it's rarely the sole cause of cloudy water. The most common reasons for persistent cloudiness after a filter change are: (1) chemistry imbalance — especially high pH, high calcium hardness, or high total dissolved solids; (2) recent heavy use without a shock treatment; (3) the new filter hasn't been properly seated (water bypassing the cartridge); or (4) the spa needs a fresh water change because total dissolved solids are too high regardless of filtration. If you've just replaced the filter and water is still cloudy, test your chemistry first, then run the spa with the cover open for 30 minutes to see if circulation improves clarity.
What's the right way to install a new filter cartridge?
Most spa filters install in under five minutes. First, turn off the spa at the breaker so the pump isn't running. Remove the filter compartment cover (typically a screw-off cap or a lift-out grate at the waterline). Slowly twist and lift out the old filter — water will drain through it, so let it. Rinse the filter housing with a hose to remove any sediment that settled at the bottom. Slide the new filter into place, making sure it's fully seated against the threaded fitting at the base. Re-install the cap or grate. Restore power and run the filtration cycle for 15 minutes to confirm proper flow and no leaks. That's it.
Should I keep a spare filter on hand?
Yes — strongly recommend it. Filter availability varies seasonally, and during peak summer months popular sizes can be back-ordered for weeks. Running a spa with no filter (or a torn/damaged filter) for even a few days can cause water clarity problems, pump strain, and chemistry instability. Most experienced spa owners keep one spare filter in storage at all times, and many take advantage of our Patio Perks rewards program to stock up annually. If you want to make this completely automatic, our Autoship program ships replacement filters at intervals you choose so you're never caught without one.
My hot tub brand isn't listed — can you still help?
Yes, often. The brands listed in the guide above are the ones we sell and service most often, but our parts team has access to filter cross-reference databases that cover virtually every spa brand made in the past 30 years. Common brands we can typically source filters for even when they're not on this page include Jacuzzi, Marquis, Master Spas, Cal Spas, Coast Spas, Beachcomber, Arctic Spas, Dimension One, and Watkins Manufacturing OEM parts. Email hello@leisuretimeinc.com with your spa's brand, model, year, and serial number, and we'll match the right filter. If we genuinely can't source what you need, we'll tell you that too — and often we can point you to the manufacturer's direct parts source.
