Concerns for my 6-mth old baby

I surfed the Internet about dustmites and realised that my own baby is at high risk daily. Read this "Some estimate that 10% of a two-year-old pillow's weight can be made up of dust mites and their droppings." I began to wonder the pillows and bolsters my Aiman is sleeping with every night. It seems that when we sleep on our pillow, we shed a lot of dead skin cells (act as food for dustmites??), humidity since we perspire and there is vapour in our breath and our body is warm (a perfect place for dustmites).

I wonder how many millions dustmites are on my pillows, bolster, mattress...
