FAQs on Arctic Spas

How do I choose the correct Arctic Spa filter replacement?

Match your current cartridge's part number first, then confirm its dimensions. Our cross-reference chart pairs original numbers with SpiroPure Arctic Spa-compatible cartridges designed to fit. If the number is missing and you can't find a label or invoice in your email, measure diameter and length and use the filter finder. Note that the filter may have shrunk slightly with use from water pressure or chemical wear.
A correctly sized SpiroPure Arctic Spa-compatible filter is designed to match your original's fit and specifications, so it can do the same job. Confirm dimensions and connections, and replace it on schedule. In most instances, it costs less than the original brand and offers comparable filtration performance.
Arctic Spas filters vary by series and model year, so read the part number on your cartridge, label, or invoice or check your hot tub's owner's manual. No number? Note the diameter, length and end-cap style, then compare them with our listings.

This can be for a number of reasons, but one may be that it is time to replace your filter for your Arctic Spa hot tub. A dirty filter can clog the system, causing a low water flow through the hot tub spa.
This depends upon the model of Arctic Spa hot tub you have. Older models may only use one or two, while newer models offer several levels of different types of filtration. It is best to consult your manual to know what type of Arctic Spa hot tub filters you will need.
