If they are clogged with dirt, they will keep the air from coming in anyway and you'll end up breathing more dust than clean air. Why air filters get dirty?

That's why the filters must be checked and washed at least once every six months. This is the easy part. Things get tougher and much unhealthier when filters are damaged. In this case, they won't be able to do their job right. In other words, they won't keep debris back and the indoor air quality at your home will be questioned.
