iPhone 13 Pro Max Case suggestions please for dusty environment

[ProMaximus]

I figure I’d ask the community for help. I’m looking for a case similar to OtrerBox or UnderArmour, but also helps keep dust out of the charging and speaker ports.
Specifically, I’m requiring a case that has some type of screen for speaker ports and the charging port is covered normally. My phones have always had a lot of dust packed in the ports and then the speakers are barely audible and the charging port gets stuffed with dirt, etc.

I had one case for a previous iPhone that met these requirements, but I forgot the brand. It was a while ago. Also, I don’t want a screen protector. I usually remove the plastic protector in the cases that I get.

Thanks in advance for any suggestions.

Life proof Fre? I mean if you want to keep dust out.. might as well get a waterproof one.

There are little silicone plugs sold on eBay that plug the lightning port - at least that’s a start.

I second the Lifeproof Fre. It’sa great case. The only ones which will keep dust out are ones which fully encapsulate your phone.

Otterbox Defender or a Lifeproof case.
