I’ve lived in the same section my entire life.
I was born up North, but my parents moved to the South shortly after that, and my body is pretty accustomed to the moderate temperatures, however it still struggles with the pollen.
My dust irritations feel like they have gotten worse every single year. My parents have always been definitely nice about swapping out the air filters in the A/C system, upgrading our whole-home air purifier, and even keeping an air filter in my bedroom for extra protection while I’m sleeping. My dust irritations feel the worst when I am waking up in the day, so I know the small whole-home air purifier definitely helps with that. I recently discovered that for the furnace, radiant floor heating could actually be a better choice than the central heater, but central oil furnaces blow heated air through the HVAC ducts and out of the air vents, but since the oil furnaces aren’t used that much throughout the year, they can tend to build up a lot of gunk and that blows out with the moderate air. Radiant heated flooring eliminates the need for air vents because it simply radiates heat into the room it is in! This would be fantastic for my dust irritations since I wouldn’t be breathing in any pollutants or built-up gunk. I’m not sure if swapping out the method in their home would be doable at this point, but it’s genuinely something that I would love to keep in mind for the future. I would like to buy a house sometime in the next few years.
