Yes. Having your carpets and upholstery cleaned removes dirt and pollutants, which makes for a friendlier breathing environment. Your carpets and upholstery does a valuable job by acting as a filter, trapping air pollutants like pollen, chemicals, tars, bacteria, fungi, cigarette smoke, and residues. Carpets and upholstery can become heavily infested with dust mites whose droppings can trigger asthma attacks. All these pollutants should be removed with regular professional cleaning.
