The L1495-B218 filaments form an interconnected, nearby, large complex extending over 8 pc. We observed NH$_3$ (1,1) and (2,2) with a spectral resolution of 0.038 km/s and a spatial resolution of 31$\"$. Most of the ammonia peaks coincide with intensity peaks in dust continuum maps at 350 $\\mu$m and 500 $\\mu$m. We deduced physical properties by fitting a model to the observed spectra.
