Background We have previously demonstrated that synthetic pillows contain significantly more Der p 1 than feather pillows. The aim of this study was to compare the accumulation of Der p 1 allergen on new synthetic and new feather pillows. Methods Der p 1 was measured in dust samples from pairs of synthetic and feather pillows placed together on 12 beds over a 12‐month period. Results After 12 months synthetic pillows contained higher concentrations of Der p 1 (19.28 μg/g; 95% confidence interval: 9.76–38.07) than feather pillows (6.45 μg/g; 2.96–14.05). There was a significant correlation between Der p 1 concentrations of pillows at 12 months and Der p 1 concentrations of the mattresses at the beginning of the study ( r = 0.72; P = 0.008 for both types of pillows). Conclusions Synthetic pillows accumulate Der p 1 more rapidly than feather pillows and the accumulation rate of Der p 1 on pillows is governed by the Der p 1 concentration in the immediate environment they are placed in.
