I know it's not what you asked, but I am asthmatic who has allergies, and it makes my eyes itch thinking about it?! If they have allergies and you just ripped out the carpet, why put it back? Can't they just adapt? It's not fun, but no point in causing problems when they can breathe easier? Just a suggestion. I'm trying to learn. I have gotten rid of the carpet. I've moved from living underground (I felt really safe during tornadoes, and electric bills were low), but I still have my cats. One thing at a time.

If they have chemical sensitivity this won't help but I would look at indoor outdoor rugs. Some styles are basically pieces of printed plastic but there are some that are woven and softer. They are very durable and can be washed off with a hose.

Rob, thank you. That is a very good point, I will see if they can adapt before purchasing anything. They were not happy with taking the rug out, so I was thinking a small/cleanable rug would help. Luckily they don't have asthma, but 3 out of 4 of us get monthly allergy shots so we try to be as allergy-proof as possible. (Knock on wood, we're all doing great with our 13 week old goldendoodle puppy!)

Deee, had not thought of an indoor/outdoor that can be hosed off, thank you for the suggestion.

That makes sense crl. I thought their rooms were pretty clean until we started taking things out for the flooring. Lots of dust on top of the curtain rods, on the top/back of the drapes, etc. Do you mind if I ask what you use for window coverings in the bedrooms? I have all different types in the house (wood blinds, roman shades, curtains) and they all seem to be dust collectors. (Or maybe I'm just a bad duster lol!)

Roller shades seem best to me, though my Dh dislikes them so I'm working on figuring out an alternative.

Cotton rugs you can wash is what was recommended to me when my son was little. He outgrew his asthma by the time he was 10/11, thanks to allergy shots, I believe, & was allergic to dust, mainly. We also ripped out ancient wall-to-wall carpet.

The asthma/allergy center where he was treated offered a class for parents on best practices - helped me a lot & they had handouts as well.

Something small enough to take outside and beat, or flip over and vacuum the back of is what I'd do. It just needs to be big enough to lay down on. My asthma boy has a 4x6 shag rug that is small enough to keep clean (and cheap enough to throw out if I have to). It makes him happy so it's worth it--you also need to get a cleanable pad under it that is cushy enough to sit on. That is the place to spend money on a kid's rug I think.

Just keep it small.
