Why You Need This Replacement Cover
- Restores Pressure Seal — A worn or cracked cover breaks the pressure seal, causing leaks and reduced filtration efficiency
- Original Fit Guaranteed — Manufactured to Sunsun's exact specifications, so it locks and seals exactly like the original
- Extends Filter Life — Replace just the cover instead of the whole unit, saving significant cost

- Sunsun CPF-20000
- Sunsun CPF-30000

Please check your filter's model number (printed on the unit body) before ordering, as covers are model-specific in size.
When Should You Replace This Part?

FAQs
Q1: Will this cover fit my CPF-30000 exactly?
Yes, this cover is sized specifically for the CPF-30000 (and separately fits CPF-20000/CPF-50000 — confirm your model before ordering, as they are not interchangeable across sizes).
Q2: Is this a genuine Sunsun part or a compatible copy?
This is an original Sunsun OEM cover, not a generic replica, so the seal and fitment match your existing filter exactly.
Q3: My filter is leaking from the top — will this fix it?
In most cases, yes. Top leaks are commonly caused by a cracked or warped cover losing its pressure seal, and replacing the cover resolves this.
