My vacuum cleaner (brand is Delphin) is the special type (about $3k; heart damn pain...) which can be used as an air-purifier, vacuum cleaner for floor and can get rid of dust mites. So my hubby will use this cleaner to clear the dust mites from our mattress and baby's mattress once in about 3 weeks. He'll also clear her soft toys of dust mites using it. I'll wash and clean her toys she plays with every now and then and wipe the surfaces of furniture etc. in the house. Came across this product at a baby fair in united sq late last yr.
