When I go to any kind of indoor event I am regularly conscious of the heating and cooling system and whether or not the locale seems to have great indoor air quality.
Well, this afternoon I was invited to a prayer dinner and talk, and there were about 60 people there.
When you have a number of people in one small room, it is mandatory that you have great indoor air quality. That means that you need to have a great strong HVAC equipment that has a great whole room humidifier or dehumidifier, depending on the need, and also great AC air filters that will filter out exhausting things and allow great things to stay in the air, however some contaminants regularly manage to get through if you buy cheap AC air vents, therefore I regularly suggest getting the best AC air filters you can. In the last multiple years, a growing body of scientific evidence has indicated that the air inside buildings can be more polluted than the outdoor air, plus most of the people in this country are regularly inside! Not only that, but those who can least afford to be affected are the people who are almost never outdoors – young people, the elderly, and the chronically ill, and people with respiratory or heart ailments. I saw no visible signs in the room that there might not be great indoor air quality! No one seemed to be coughing or sneezing, there was no visible dust somewhere, and breathing deeply was a relief, then one thing you should regularly try to do is try to increase ventilation in your property or office. The more air that circulates in from the outside, the cleaner your air is likely to be. When fall comes, I am in heaven because I turn off the AC and open the windows.
