They kill bacteria and combat unpleasant odors
Studies have shown that the air inside homes and buildings is typically more polluted than the outdoor air. The breathing air can be up to ten times worse than outdoor pollution.Contained areas cause potential contaminants to build up in higher concentration than open spaces. Because people spend approximately 90% of their time indoors, the hygiene of the air is especially important. There are sources of concern in every room of the house. Pet dander, mold, pesticides, asbestos, particulate matter, dust, VOCs from a variety of products, tobacco smoke and all sorts of toxins originate from cleaning supplies, paints, insecticides, building materials and more. When people breathe in these pollutants, they are at risk of a long list of health concerns. Headaches, congestion, sneezing, coughing and difficulty sleeping are a few of the consequences. Exposure can lead to aggravated symptoms of asthma and allergies as well as respiratory infection. Fortunately, the HVAC industry has made great strides in the engineering of indoor air quality accessories. There are whole-home air purifiers that install into the ductwork to treat the air as it passes through and provide improvement to every square inch of air reached by the furnace and air conditioner. Modern air purifiers capture over ninety percent of particles smaller than a grain of table salt. They kill bacteria and combat unpleasant odors. There are models that send out positive and negative ions to actively interrupt the DNA and render pathogens harmless. They cause particles in the air to clump together and become more easily filtered out. Air purifiers operate quietly and 24/7 and require only annual maintenance.
