I have been looking into indoor air quality devices. I am really sensitive to odors, dust and humidity. It makes sense to spend a little money to be more comfortable. For odors, I am thinking about getting an air purification system. They can eliminate odors such as pet smells, cooking fumes, debris and dust in the indoor air conditions. You get fresher, cleaner feeling air. When it comes to how dirty my indoor air quality is, an air purifier can only go so far. I found in my research that there are HEPA filters that are specially made to remove more dust from the indoor air quality. They have smaller holes to catch more dust from going into the HVAC system. The less dust your HVAC absorbs, the healthier the air quality and the better your heating and air conditioning system runs. On top of this, a little ductwork cleaning can go a long way. Why bother making sure the HVAC is clean if the ductwork attached has hair and debris in it? Lastly, for humidity issues I want both a humidifier and dehumidifier. They can each have their own season to work and make me comfortable. In the winter my indoor air conditions are so dry. I get static filled hair, chapped lips and bloody noses. I also experience issues with keeping the house feeling warm enough. Adding humidity will solve all those issues. In the summer, removing the excess moisture stops bugs and mold from forming in the home. I also won’t experience any issues with my wood furniture swelling.
