Hi, @larry68 - I wanted to let you know I moved your post about dust mite allergy and watery eyes to its own discussion, as I thought it merited it.

I personally have a dust mite allergy and have had trouble with watery eyes. Vacuuming a whole house or hanging around in a garage or unfinished basement (which most people don't dust) can get to me. I've used lodoxamide (Alomide) eye drops daily (or more recently, as needed) and then my doctor switched me to cromolyn 4 % ophthalmic solution, due to availability or my formulary (not sure which). Using drops does help with any itching or watering.

My husband and I also just got a new HVAC. It has helped with its improved filtration for my dust allergies in general. I realize that no one just runs out and gets a new HVAC unless absolutely necessary, as they are expensive and not a fun way to spend money. But I have also read you can upgrade just the filtration part of an HVAC, which I found interesting.

Are you saying your home is a dust bowl because of its orientation? Number of objects in it?

Did you get to try the eye wash solution? If so, did it help?
