It has been shown that the filtration combustion front 
of gases is resistant to small perturbations at any asymmetry between 
the diffusion and thermal transport. A qualitative analysis of the 
perturbation development with time confirming that the diffusion-thermal 
asymmetry does not influence the front stability has been carried 
out.
