This filter will convert all raw HTML to code in backticks, with syntax highlighting. Save it as raw2code.lua and include --lua-filter=raw2code.lua on the pandoc command line.

local code_for = {
  RawInline = pandoc.Code,
  RawBlock = pandoc.CodeBlock
}
local function raw2code (elem)
  if 'html' == elem.format then
    return code_for[elem.tag](elem.text, { class = 'html' })
  end
  return nil
end
return {
  {
    RawInline = raw2code,
    RawBlock = raw2code
  }
}

If you simply want to ignore all raw HTML elements then I think that a lua filter that ignores all RawInlines (perhaps only those with format="html") will work for you. But if some HTML elements need to retain their HTML meaning then more logic will be needed. For example, this document:

% cat raw.md
This is <b>bold</b> text.

gives this HTML:

% pandoc raw.md
<p>This is <b>bold</b> text.</p>

...but with this filter:

% cat raw.lua
function RawInline(raw)
  if (raw.format == 'html') then
    return {}
  end
end

...it gives this:

% pandoc raw.md -L raw.lua
<p>This is bold text.</p>

Note that Markdown allows you to include HTML elements, so whenever you write e.g. <h1> directly, Pandoc assums that's what you're doing and will put an <h1> tag in the html (or epub) output.

You'll want to mark the tags as code, which you can do with backticks: `<h1>`.
