Yes, good air quality will quash ongoing transmission "on average" over time.
Fresh air also has a significant up side for clarity of thinking. People only tend to complain about opening windows if the weather's cold: chills and heating bills!
Filters likewise are mostly up side except for the cost.
But the "on average, good air quality quashes ongoing transmission" can still include infections in the meantime - esp downwind of an infectious person.
LFT tests... they're not pointless, because they'll find some of the most-infectious people, but they aren't reliable. Lots of false negatives at middling viral loads.
Even a negative NAAT result only means "negative now and likely for some hours", not necessarily "still negative tomorrow".
Testing on arrival is a logistical challenge. It's slow (e.g. Pluslife ~30 mins, LFT ~15), so you've got people waiting around whose status is unknown.
People testing beforehand: most don't have access to NAAT. And it relies on trust, which is not necessarily wise when so many people don't genuinely believe it's important.
Also, each test is for one or more specific illnesses: e.g. a covid test won't catch someone coming in with flu or measles.
There's a reason why people do still mask even though the other things exist.
