Aim : To measure the effect of an in‐line microaerosol filter on spirometric values in cystic fibrosis (CF). Methods : Twenty‐six subjects with CF undertook a randomized, open, cross‐over comparison of spirometry with and without an in‐line filter. Results : The filter had no significant effect on spirometric parameters nor was there any order effect. Measurement error was unrelated to the magnitude of the measurement. Conclusion : In‐line microaerosol filters do not affect spirometric values or variability in children with CF.
