Hello, I have  a xTool Smoke Purifier connect to my P2. Even with brand new filter kit installed I still smell the fume very well.  I just found that I have a air leak all around the the cover of the purifier when it's running. I wonder if it's for somethin like air pressur or it's not supposed to be that way and have a seal problem, or my smoke purifier is defective. I also have some air leaking around the purifier handles. 

Any idea or suggestion ?

Thank you.
