because of Covid, we purchased 3 home air cleaners and I took one to basement for use near the long arm. I really do notice a difference in how congested I feel after spending 3-4 hrs quilting.

I have a lot of dust here in Arizona because we are in a drought. My fabrics are in a closed cabinet so they are dust free, but there is a lot more to make up for it. I use cotton thread so I clean my bobbin area often. Hope you cough gets better. mabe you have to wear a mask when you are sewing.

I also have asthma and found using an inexpensive cool-mist humidifier helped tamp down the dust in my sewing room.

I also have asthma and allergies so I prewash all my fabrics and I limit the amount of Best Press or sizing I use. I also use polyester thread. I never sew fleece fabric and rarely use flannel.

With the disposable face masks being easy to find everywhere stock up. Cut off the back layer and the front will be enough to stop the lint. It will be light and weightless and easy to wear while sewing.
You'd be surprised at how many employees do this now to wear a mask all day.

I have used a knee high stocking and elasticized it round my vacuum hose and cleaned out the dust that way.
