Short answer
A practical Arctic Spa filter replacement path for UK owners
If your hot tub is a supported 2020+ Custom Series model, Kit v3 replaces the filter connection below the skimmer covers. You keep the existing covers and install two compatible generic cartridge filters on each adapter. The result is a serviceable setup with filters that can be removed, rinsed, and replaced without buying another proprietary Pro Filter set.
What the kit changes
Keep the spa. Change the filter connection.
The adapter is purpose-built for the matching Custom Series skimmer setup. It does not modify the shell, pump, plumbing, or control system.
Choose generic cartridges
Buy compatible filters separately by part number and dimensions. UK pool and spa suppliers may list the same cartridge under different cross-reference numbers.
Install Kit v3
Fit the adapter components into the existing skimmer area, install two cartridges per adapter, and slip the original skimmer covers back over the filters.
Compatibility first
Model name alone is not enough.
Arctic Spas reused several model names across different generations. Kit v3 is confirmed for the supported 2020 and newer Custom Series configuration, not every spa that carries one of these names.

Buying replacement filters in the UK
Search by cartridge number and dimensions, not by spa brand.
The compatible cartridges were not created specifically for Arctic Spas. UK listings may use imperial dimensions, metric dimensions, or one of several established cross-reference numbers for the same cartridge family.
| Brand | Search number | Outside size | Top and bottom openings |
|---|---|---|---|
| Unicel | T-380 | 2 3/4 × 9 3/4 in About 70 × 248 mm | 1-1/16 in open / open About 27 mm / 27 mm |
| Filbur | FC-3060 or FC-3061 | 2 3/4 × 9 3/4 in About 70 × 248 mm | 1-1/16 in open / open About 27 mm / 27 mm |
| Pleatco | PH6 | 2 3/4 × 9 3/4 in About 70 × 248 mm | 1-1/16 in open / open About 27 mm / 27 mm |
| SpiroPure | SP-PS-3060 | 2 3/4 × 9 3/4 in About 70 × 248 mm | 1-1/16 in open / open About 27 mm / 27 mm |
| Pentair | 57000500 | 2 3/4 × 9 3/4 in About 70 × 248 mm | 1-1/16 in open / open About 27 mm / 27 mm |
Before purchasing from any UK seller:
Each adapter uses two compatible cartridges. Match both the part-number family and all four physical dimensions. Product availability, package quantity, and seller listings change. If the measurements do not match, do not force the cartridge onto the adapter.

★★★★★Seriously just get one. It fits perfectly, filters are soooo much cheaper and easier to clean weekly, bi-weekly, or whatever your timeline is. If it’s snug just keep going it will slide into the slot trust me! I’m happy I found this it’s constructed well I can’t say enough good things about it. Thanks Ryan.
★★★★★I am a pool and spa professional who purchased these for a customer. I service their pool and spa weekly and while I'm a big fan of Arctic Spa's, these new throw away filters that Arctic has moved towards were my biggest complaint about them. This completely fixes that issue and converts the filter cartridges into something you can actually service! There's no good reason for throw-away filters. This design of filter cartridge has been been around for decades and it's a tried-and-true technology that simply works. Thank you for creating a product that allows for a serviceable item to be serviced!
★★★★★fantastic product! fit well. as soon as my OEM filters started needing replacement after 2 1/2 months, I thought holy cow this is going to be an expensive spa to maintain, considering everything else in the spa works fantastic. This filter situation was going to be a real problem and I saw this online and thought wow that’s the solution! bought it, installed it, water was clear the next morning. fits Fantastic, filters are washable. Great product. thank you
UK buyer FAQ
Answers before you order
Can Spa Filter Adapter Kit v3 ship to the United Kingdom?
Yes. Orders ship from Utah, USA, and live USPS shipping services and prices are calculated at checkout after you enter a UK delivery address. International transit and customs processing can affect delivery time.
Is the adapter kit an Arctic Spa filter?
No. Kit v3 is an independent aftermarket adapter. It changes the filter connection in compatible 2020+ Arctic Spas Custom Series hot tubs so owners can install compatible generic cartridge filters. The filters are required and sold separately.
Which Arctic Spa models are compatible?
Kit v3 is confirmed for supported 2020 and newer Custom Series models: Summit XL, Summit, Tundra, Kodiak, Klondiker, Frontier, Yukon, Cub, Arctic Fox, Ocean, and Okanagan. Model names were also used in older generations, so confirm the year, series, and filter-cover configuration before ordering.
Which generic replacement filters should UK owners search for?
Common compatible filter numbers include Unicel T-380, Filbur FC-3060 or FC-3061, Pleatco PH6, SpiroPure SP-PS-3060, and Pentair 57000500. Confirm an outside diameter of about 70 mm, a length of about 248 mm, and 27 mm openings at both ends before buying.
Can Kit v3 replace an Arctic Spa Pro Filter?
Kit v3 is not an exact replacement cartridge. It replaces the filter connection below the original skimmer covers in a compatible 2020+ Custom Series spa so you can use compatible generic cartridges instead of another complete proprietary Pro Filter set. The generic cartridges are required and sold separately.
Does Kit v3 work with Silver Sentinel or older hybrid filter systems?
Silver Sentinel, threaded, hybrid, and other older filter descriptions can refer to different Arctic Spa generations and configurations. Kit v3 is confirmed only for the supported 2020 and newer Custom Series setup shown in the compatibility guide. Do not assume compatibility from the model name or filter description alone.
Where are the generic filters positioned after installation?
The adapters sit in the existing Custom Series filter bay below the original skimmer covers. Install two compatible generic cartridges on each adapter, then return the original covers to their normal position.
Are prices shown in pounds sterling?
No. SpaFilterAdapter.com charges in US dollars. Your bank or card provider determines the pound sterling conversion and any foreign transaction fee. The product price and available shipping charge are shown before payment.
Will UK orders have VAT, customs duty, or handling charges?
UK orders may be assessed import VAT, customs duty, carrier handling charges, or other fees. Any charge not shown at checkout is not included in the product or shipping price and is the customer’s responsibility. UK import rules and exchange rates can change.
Will the Arctic Spa app still say Filter Not Present?
Yes. Compatible generic filters do not contain the RFID chip used in proprietary Pro Filters, so the Filter Not Present notice is expected. Continue following a regular cleaning and replacement schedule and pay attention to separate flow, water-care, or equipment warnings.
