Why do you think we feel like this in our home?

We’re currently renting a townhome. The house is 3 years old. We were the first people to live here. We used the have a HORRIBLE vacuum. It would literally blow dirty/dust everywhere. It would smell burnt after. There was literally no point in vacuuming.

For the past year it’s been BAD in our house especially our bedroom. We’re both always thirsty, have a dry throat, as soon I get into bed my nose burns a bit and instantly gets stuffy, my eyes sometimes hurt, my lips are dry. I haven’t been sleeping very well lately. Its just bad. We keep thinking maybe it’s dry, so we run a humidifier which helps a but but idk...our sons monitor says it’s between 43-46% humidity which I think 30-50 is considered normal?

We purchased a dyson vacuum in hopes that it would help as we thought maybe our house is dusty from the old vacuum and all the construction (the house is 3 years old, they were doing construction on our street for a year when we moved in). When we first vacuumed using the dyson it was BAD. We had to keep emptying the canister after every room and twice in the living room (which isn’t very big). Our vacuum had dust stuck inside now so we have to clean it out. But it’s still bad in here...

So now we’re thinking maybe we should get the carpets professionally cleaned (as all the dust obviously is sitting in there) and get the ducts cleaned as well (we also had problems with our ac always getting clogged up almost every hot day last summer and then just today it happened again). What do you think?

I feel worried because we have a 2 year old and one on the way. We NEED to get to the bottom of this, or move. I’m done feeling like this! I don’t feel like this when I’m out or when I’m at someone else’s house...just our house.

Any ideas of what it could be? Anyone else experience this?

Wanted to add that yes, we change the ac filters every couple months.
