Please Tell Me What I Can Do???

One thing that will help is to get rid of any ceiling fans. Ceiling fans blow the dust around to every nook and cranny in the house. Once I stopped using ceiling fans, the dust in my house significantly reduced. Now I just use stand fans to help circulate the air in a room I am in at the time - they aren't on all day long. They aren't pretty but having dust everywhere is even worse. My kids have a form of asthma and this has helped as well.

The Ionic Pro works good at getting rid of dust in the air. Definately use the suggestions below to seal the air leaks in your house, that will help too. You can also get foam pads that go behind plug outlets to seal them.

Try an air purifier. They are kinda espensive, but cheaper than risking your health.

Get a humidifier! Or get two! Get the one(s) with the highest output. Some say 1 gallon a day, others are up to 2 gallons a day. If you can, get the 2+ gallons per day. This will put moisture in the air and help settle the dust. Remember: Air conditioning pulls moisture OUT of the air. HTH-GL!!

You may need to seal the house. Put an extra bead of caulking around all the windows. You can get a storm door that reduces dust for the front door or at least make sure there are no gaps around it. If you can see daylight anywhere around front or back door than you dont have a good seal. You can get a roll of stuff that sticks in the door jam that provides a good seal at the hardware store. You can get a company to come out and clean your duct system. Otherwise, everytime you turn on a/c or heat dust blows out every duct in every room. At the very least, chage the existing filter on the a/c unit once a month. Take off dusty shoes before entering the main house. Keep your yard watered to cut down dust and spray a weed and feed to eliminate asthma caused by weeds. whew! That's a lot of work, but those things will significantly cut down your dust and hopefully your asthma attacks.

My doctor prescribed Nasonex spray daily and Singulair at night. Also, you might try a humidifier in your home to drop the dust in your house from the air and/or change your AC filter more often. This has been the worst year for allergies!

Probably not just dust that's causing your asthma to act up - allergy season has been bad this year. You should probably see your doctor to review your asthma meds. Good luck!

I agree with sealing your house and making it 'air tight'. The less unfiltered air coming into your house the better. AC's help to filter the air as it comes in and definitely keep up with changing the air filters (or cleaning them if washable...just make sure you use soap and water when cleaning and not just water).
I have asthma and had attacks every other day when I first moved to this state. I recommend going to an asthma specialist (Pulmonary Doctor) to get your asthma under control through medication. There are plants that grow in North Texas and no where else on this planet. These plants wreck havoc on asthmatics and are most likely mixed in with the dust around your house.
I do not agree with using a humidifier though. During the summer here the humidity outside is already high and I'm sure inside the humidity is at a reasonable level already. You can use one at night but only in your bedroom and only while you sleep. I'm also thinking that if you use a humidifier all the time you'll be creating (if not adding) mold and mildew to your house and black mold is a major health hazard here.

Using a humidifier during the winter is highly recommended though. The winter weather tends to be dry so adding moisture to the air will not only add warmth, but it'll alleviate having dry skin.

If your house is located on a dirt/gravel road, you can place a request with the County Road Maintenance Dept. for "dust control" products to be applied on the road in front of your house. This service does not cost you a cent and it reduces the dust a lot.

I agree with the humidifier advice.

If dust is an issue, make sure you are changing your air filters for your air conditioning every month and that you are using a high quality one. That should keep the dust down in your home. You can also try a portable air purifier. Keep one in the main living area and maybe one in your bedroom. Or just start with one to see if it helps before you invest in 2, they can be pricey.

Ceiling fans make the room dustier from my experience.
