The weather is getting cooler again and it means our windows will remain shut for most days. I hate to not have fresh air circulate inside the house but I wouldn't like to get frozen by chilly air as well. So what I do is to make sure I replace our HAVC filters as often as necessary to keep air pollutants at bay. My hb is prone to allergies so I use HAVC filters that are effective in reducing pollen, dust, pet dander, and other fibers from our indoor air.
