Asthma in Children
Conditions
Brief summary
The goal of this pilot study is to investigate if installing an air purifier in the homes of children and young people with asthma improves their asthma outcomes. The main questions it aims to answer are: * Does installing an air purifier in the homes of children and young people with asthma improve their asthma outcomes * Is the use of an air purifier in the home acceptable to children and young people and their families? Children and young people with asthma attending our clinic will be selected at random to be invited to take part. For those that take part, an air purifier (Rensair Ltd. - Rensair Compact) will be installed in their home for a one-year period. Data will be collected on numbers of asthma attacks, rescue oral steroids, quality of life, symptoms, lung function at the beginning and at three-monthly intervals throughout the study period. The acceptability to children and young people and their families taking part in this study of using an air purifier in their home will also be assessed.
Detailed description
The goal of this pilot study is to investigate if installing an air purifier in the homes of children and young people with asthma improves their asthma outcomes. The main questions it aims to answer are: * Does installing an air purifier in the homes of children and young people with asthma improve their asthma outcomes (including reduction in asthma exacerbations, improvement in symptom control, improvement in quality of life). * Is the use of an air purifier in the home acceptable to children and young people and their families?

| Forced expired volume in one second (FEV1) | 12 months | Spirometry measurements using ERS/ATS criteria and Global Lung Initiative Reference z-score |
| Forced vital capacity (FVC) | 12 months | Spirometry measurements using ERS/ATS criteria and Global Lung Initiative Reference z-score |
| FEV1:FVC | 12 months | Spirometry measurements using ERS/ATS criteria and Global Lung Initiative Reference z-score |
| Measurement of fraction of exhaled nitric oxide (FeNO) | 12 months | Fraction of exhaled nitric oxide measurements |
| Acceptability to children and families participating of using an air purifier in their home | 12 months | Acceptability to children and young people and their families taking part in the study in terms of use of air purifier in their homes - assessed by questionnaire |
