The width of the f1(1285) → e+e− decay is calculated in the vector meson dominance model. The result depends on the relative phase between two coupling constants describing f1 → ρ0γ decay. The width Γ(f1 → e+e−) is estimated to be - 0.07 − 0.19 eV. Direct f1 production in e+e− collisions is discussed, and the e+e− → f1 → a0π → ηππ cross section is calculated. Charge asymmetry in the e+e− → ηπ+π− reaction due to interference between e+e− → f1 and e+e− → ηρ0 amplitudes is studied.
