change it by how dirty it is , not by how long it is in there .

1 month, 30 days-- it is all the same
I usually check mine every two weeks during the winter. If it is dirty, i then pull it out and install another new one. They don't cost very much, and can be changed easily. They just slide through a slot in the tinwork.
every 3 - 6 months depending on the type of filter (monthly for the really cheap filters)
I was told every 3 months but I change mine every month.
depends on dirt and dust in home......minimum of every heat or cooling season or every six months
I Check it every month but if I can see light through it then I leave it in. Sometimes it will last 3 or 4 months, sometimes 1. If yours where that bad you might want to check the condenser under your fridge. Vacuum the dusty coils under there before that starts acting up
I usually clean mine once a month (I rinse it out. There are some filters that cannot be rinsed). This might be extreme. I replace the filter 2 times per year. If you cannot rinse off the filter I would replace it every 3-4 months.
Which is depend on the time of using I think. About 2 moths
