Quiet matters most
A bedroom unit runs while you sleep, so check the noise level (dB) in the product description and prefer a model with a quiet / sleep mode. Inverter units also tend to be quieter because the compressor does not hard-start.
Size for the bedroom
Most Malaysian bedrooms suit 1.0–1.5 HP. A master bedroom with an attached bathroom or a glass wall may need 1.5–2.0 HP. Use the HP-to-room-size guide to confirm, then compare models in the catalogue.
Keep it healthy
Clean or replace the filter regularly and service the unit yearly. ATORA stocks filters and spare parts so routine maintenance stays easy.
