What kind of air purifier did you buy? I am very allergic to dust and smoke too. I have been considering buying an air purifier.
I bought an Ionic Pro years ago and like it a lot. It is not a whole house device. I recently broke it and DH is trying to fix it. It’s a large size one, it’s around 15 years old maybe. No filters, just metal blades to wipe and needs a good blow out with compressed air, or vacuum out, periodically. I have asthma and allergies and without it the air quality is much worse. I am allergic to dust, smoke, mold and other stuff. We have a wood stove and I can handle with the air filter and even without as long as the draw on the stove is good.
