Best Praise
+8 ptsβIβve been using the Levoit Core 400S for a few months and it actually makes a noticeable difference, my room feels less dusty and my allergies are way better, even on highβpollution days. Itβs surprisingly quiet on the lower fan speeds, and the smart sensors mean it only ramps up when needed, so itβs great for bedroom use without annoying noise at night.β
