We report results of a deep all-sky search for periodic gravitational wavesfrom isolated neutron stars in data from the first Advanced LIGO observing run.This search investigates the low frequency range of Advanced LIGO data, between20 and 100 Hz, much of which was not explored in initial LIGO. The search wasmade possible by the computing power provided by the volunteers of theEinstein@Home project. We find no significant signal candidate and set the moststringent upper limits to date on the amplitude of gravitational wave signalsfrom the target population, corresponding to a sensitivity depth of 48.7[1/$\sqrt{{\textrm{Hz}}}$]. At the frequency of best strain sensitivity, near100 Hz, we set 90% confidence upper limits of $1.8 \times 10^{-25}$. At the lowend of our frequency range, 20 Hz, we achieve upper limits of $3.9 \times10^{-24}$. At 55 Hz we can exclude sources with ellipticities greater than$10^{-5}$ within 100 pc of Earth with fiducial value of the principal moment ofinertia of $10^{38} \textrm{kg m}^2$.
