(5) Although there is evidence that some air cleaning technologies improve indoor air quality, further research is needed before any of them can be confidently recommended for use in indoor environments.Ībstract = "Air cleaning techniques have been applied worldwide with the goal of improving indoor air quality.
For that purpose, a standard test room and condition should be built and studied. (4) To compare and select suitable indoor air cleaning devices, a labeling system accounting for characteristics such as CADR, energy consumption, volume, harmful by-products, and life span is necessary. (3) The existing data make it difficult to extract information such as Clean Air Delivery Rate (CADR), which represents a common benchmark for comparing the performance of different air cleaning technologies. (2) Particle filtration and sorption of gaseous pollutants were among the most effective air cleaning technologies, but there is insufficient information regarding long-term performance and proper maintenance. The conclusions are that: (1) None of the reviewed technologies was able to effectively remove all indoor pollutants and many were found to generate undesirable by-products during operation. During this process 59 articles were deemed conclusive and their results were used for final reporting at their second meeting. Each article was assessed independently by two members of the panel and then judged by the entire panel during a consensus meeting. Of these, 133 articles were finally selected for detailed review. These articles were reviewed by the panel using predefined inclusion criteria during their first meeting.
AIR DOC CLEANERS JC FULL
Over 26,000 articles were identified in major literature databases 400 were selected as being relevant based on their titles and abstracts by the first two authors, who further reduced the number of articles to 160 based on the full texts. To summarize what is known regarding the effectiveness of fan-driven air cleaning technologies, a state-of-the-art review of the scientific literature was undertaken by a multidisciplinary panel of experts from Europe, North America, and Asia with expertise in air cleaning, aerosol science, medicine, chemistry and ventilation. Some air cleaners are largely ineffective, and some produce harmful by-products. The effectiveness of applying these techniques varies widely, and pollutant removal efficiency is usually determined in controlled laboratory environments which may not be realized in practice. And bird food scattered on the ground can attract unwanted rodents.Air cleaning techniques have been applied worldwide with the goal of improving indoor air quality. Moldy or spoiled food is unhealthy both for birds and for your outside pets. Rinse thoroughly and allow to dry before refilling.Ĭlean the ground below your feeders, too, to prevent a build-up of hulls, uneaten seeds, and other waste. To clean your feeder, take it apart and use a dishwasher on a hot setting or hand wash either with soap and boiling water or with a dilute bleach solution (no more than 1 part bleach to 9 parts water).
Clean your feeders about once every two weeks, more often during times of heavy use or wet weather or if there have been reports of salmonella in your area or you have seen sick birds in your yard. Bird droppings and other contaminants may also spread infectious bird diseases. Moldy or decomposing seeds and hulls that accumulate on feeder trays can make birds sick. Cleaning your bird feeders regularly helps keep your backyard birds healthy.
