We calculate $m_{ud}=(m_u+m_d)/2$, $m_s$, $f_\pi$ and $f_K$ in the quenched
continuum limit with UV-filtered overlap fermions. We see rather small scaling
violations on lattices as coarse as $a^{-1} \simeq 1 \mathrm{GeV}$ and
conjecture that similar advantages would be manifest in unquenched studies.
