What is covered by the de minimis safe harbor election?

I have read several TT posts and other public posts on the de minimis safe harbor election and remain confused from conflicting perspectives.

I purchased several items for rental properties that were all less that $2500 each. I would appreciate feedback on which of these are covered by the de minimis safe harbor and which must be depreciated.

Replaced 9 windows ($2000 each)

Replaced vinyl flooring planks (not glued down)

Replaced carpet (tacked in place - not glued down)

Replaced curtains

Light shades (can easily be removed)

Television

Heater

Vent fans

Thanks in advance for your feedback
