OK–this one may not be as “fun” as the other items on this list, but according to environmental toxins expert and certified holistic health coach Lara Adler, if you have a heating, ventilation, and air conditioning (HVAC) system in your home, it’s probably blowing dust around.
As she previously told mbg, “If people have an HVAC system, I do encourage them to change their furnace filters more frequently than recommended because the system is probably going to be on all the time through the winter.”
Look for a filter with the highest MERV rating your HVAC system can handle, which stands for “Minimum Efficiency Reporting Values.” (It’s essentially a rating for a filter’s ability to capture particles.) “The higher the MERV rating, the better the filter will be at capturing particulate, allergens, dust, and mold spores,” Adler adds.
