* Regular inspections to indicate for presence of mold or other toxins * Adequate maintenance of all<unk>  mechanical systems * Toxin-absorbing plants, such as sansevieria * Roof shingle non-pressure cleaning for removal of algae, mold, and Gloeocapsa magma * Using ozone to eliminate the many sources, such as VOCs, molds, mildews, bacteria, viruses, and even odors. However, numerous studies identify high-ozone shock treatment as ineffective despite commercial popularity and popular belief. * Replacement of water-stained ceiling tiles and carpeting * Only using paints, adhesives, solvents, and pesticides in well-ventilated areas or only using these pollutant sources during periods of non-occupancy * Increasing the number of air exchanges; the American Society of Heating, Refrigeration and Air-Conditioning Engineers recommend a minimum of 8.4 air exchanges per 24-hour period * Increased ventilation rates that are above the minimum guidelines * Proper and frequent maintenance of HVAC systems * UV-C light in the HVAC plenum * Installation of HVAC air cleaning systems or devices to remove VOCs and bioeffluents (people odors) * Central vacuums that completely remove all particles from the house including the ultrafine particles (UFPs) which are less than 0.1 μm * Regular vacuuming with a HEPA filter vacuum cleaner to collect and retain 99.97% of particles down to and including 0.3 micrometers * Placing bedding in sunshine, which is related to a study done in a high-humidity area where damp bedding was common and associated with<unk>  * Lighting in the workplace should be designed to give individuals control, and be natural when possible * Relocating office printers outside the air conditioning boundary, perhaps to another<unk>  * Replacing current office printers with lower emission rate printers * Identification and removal of products containing harmful ingredients
