Air purifiers often make an enticing promise. This is an appliance that helps clean the air in your home while getting rid of all the impurities including smoke, dust, dirt, odor, and pet dander.
Air purifiers consist of a filter or multiple filters and a fan that sucks in and circulate air. As the air is pushed through the filters, particles and pollutants are captured and clean air is pushed back in the living space.
While some air purifiers are equipped with reusable filters, others come with filters that need to be changed at regular intervals.
