How do I remove a filter on a website

Hello Mi22ke,

Welcome to Apple Support Communities!

We want to help you check for filters that might be preventing you from viewing a website.

You'll want to check your Screen Time settings for web content here:

"Prevent web content

iOS and iPadOS can automatically filter website content to limit access to adult content in Safari and other apps on your device. You can also add specific websites to an approved or blocked list, or you can limit access to only approved websites. Follow these steps:

1. Go to Settings and tap Screen Time.
2. Tap Content & Privacy Restrictions and enter your Screen Time passcode. 
3. Tap Content Restrictions, then tap Web Content.
4. Choose Unrestricted Access, Limit Adult Websites, or Allowed Websites. 

Depending on the access you allow, you might need to add information, like the website that you want to restrict."

This Apple Support page has the full details: Use parental controls on your child's iPhone, iPad, and iPod touch - Apple Support

You might need to contact the device owner if it's a school or work owned device.

Or if you're seeing a different issue or any error messages, please provide more details so we can better assist.

We hope this helps.

Cheers!
