Frequently Asked Questions

What are the dimensions of the PAS50SV-F2M?

The PAS50SV-F2M measures 6.75 inches in outer diameter and 8 inches in length, with a handle top and open bottom. It provides 50 square feet of filtration area. Always measure your existing cartridge or check the label inside the filter housing before ordering - outer diameter and length are the two critical dimensions, but end-cap style must also match.

What other part numbers are interchangeable with the PAS50SV-F2M?

The PAS50SV-F2M is interchangeable with 6CH-502, FC-0311, and OEM equivalents including Artesian 06-0005-12, Artesian 06-0006-12, Artesian 06-0056-12, Artesian 60506. All of these share the same 6.75" OD × 8" dimensions and handle top / open bottom end caps. When buying a cross-reference, confirm the end-cap style matches - a small difference in cap design can prevent proper seating in your filter housing.

How often should I replace a PAS50SV-F2M filter cartridge?

The PAS50SV-F2M (50 sq ft) is a mid-size spa filter. Plan on 12-24 months between replacements depending on how heavily the spa is used. Spas used daily or by multiple people will wear out filters faster than a spa used once or twice a week. A good rule of thumb: inspect it at every water change (every 3-4 months) and replace it when the pleats show tearing, channeling, or persistent discoloration.

How do I clean a PAS50SV-F2M filter cartridge?

The PAS50SV-F2M has a handle on top, making it easier to lift out of the housing without touching the filter media. Remove the cartridge from its housing and rinse thoroughly with a garden hose, directing the stream at a 45-degree angle between the pleats - work from top to bottom, rotating around the cartridge. Avoid pressure washers, which collapse the pleats and permanently reduce filtration efficiency. For a deeper clean every 3-4 months, soak overnight in a hot tub filter cleaner solution, then rinse thoroughly. Never reinstall a wet cartridge if you're using a cartridge with a closed end - let it dry to prevent trapping moisture inside.

Which hot tubs and spas use the PAS50SV-F2M filter?

The PAS50SV-F2M is compatible with the following models: Artesian Island Series, Artesian South Seas, Artesian Platinum Elite. Always cross-check your spa's owner manual or the label inside the filter compartment to confirm the correct part number.
