Allergy Friendly Carpet for Travis

We have a gorgeous son Travis 5yrs old, who is an asthma, eczema and allergies child.

and unfortunately our house has really old carpet that is causing him a lot of grief, the carpets at least 20 years old and seems to constantly release fibres, if you roll on the carpet you get covered in them, I am going through heaps of vacuum bags as I am trying to vacuum regularly to minimise the effect on Trav but it doesn't seem to help a lot. Travis has a hay fever type reaction, a lot of sneezing, coughing and puffy eyes, he also has had more asthma since we've lived here than ever before.

We would really like to replace at least the carpet in his room and in the lounge, places where he plays on the floor, but we put all our money into buying the house and repairing the roof, we would really appreciate any help so we can get this sorted as soon as possible.

Most of his allergies are pretty manageable now, his food allergies(nuts, dairy, egg, sulphur) and dog allergy, and usually his hay fever is manageable but its been constant since living we moved in in march. We cleaned the carpets with a rug doctor and the rest of the house for dust deliberately for Travis when we moved in. But feel were not going to get rid of this problem unless we replace the carpet.

Any help you can give would be soooo amazing and greatly appreciated.

Thank you for your help and kindness
