The Infernal Smell!, After much activity in my room it has adopted a strange smell!! Options

I am in a need of help with my sacred space.After many energy activities my space adopted a strange smell I cant get rid off.I tried everything, nothing works. I didn mind very much but now it is starting to irritate my senses.I dont have an unvanted guest, just a smell ( and I dont have a rotten animals in the room). Any advise or exp. needed. thanks

You see, the problem is than I used all kinds of aircleaners, it doesnt work. I dont detect any kind of unwanted entityes in my space which could create the smell. I open my windows very often, but I shall try that bowls and roses thing, I hope it helps but I doupth it will.If you think of anything more let me know. Thanks
