Have a look here.
Getting the blue SDR from aliexpress is all most people need + a decent antenna.
An extra filter is only needed in some circumstances.
You can always try and get a 1090 SAW filter if you have strong interference nearby (they should be available relatively cheaply via ali or ebay).
Then test with and without the filter what gives better reception.
