Filter Size

Can anyone tell me what size filter this is and what o-ring it needs?

thanks

You have a Hayward Pro-Grid Series filter. The filters dimensions will determine your specific square footage. Click here to be directed to the brochure which has all of the Pro Grid dimensions in order for you to confirm.  Also, the lid o-ring is listed on key 12 on this parts diagram.

90% sure that’s a 60 sq ft
