logistics of taking air filter out for emissions test?

i heard that taking out the air filter would significantly in helping a car pass an emissions test. Makes sense to me, im just wondering if it is "safe" to drive for 30 - 50 mins without an air filter, as id like to warm up the car too. Whats the worst that could happen? its fuel injection if that matters. thanks! my car barely failed last time on the NO or NO3 count (or whatever nitrogen something they measure), also had not the best gas in there at the time. i would just like to double make sure im not going to have to go back for a 3rd time... any other simple tricks appreciated too. thanks!
