Here are his results. Eek. Other results were zero.
So today I did a deep clean of the bedroom , new pillows, washed bedding, vacuumed under and behind everything, cleared bags etc in bottom of wardrobes and removed most things to garage and wiped everything down with white vinegar.
Bought new dust mite vinyl covers for mattress and pillows, and air purifier that removes spores, dust, and voc and have had that going all day. The air smells fresher. Hopefully new stuff doesn’t off gas but if it does the purifier should remove it.
What else should I do?
We’ll see if he feels any better after all that!
