Mitsubishi Electric

M Series MSZ-LN (Premium)

Principal bedrooms, main living rooms and consulting rooms where air quality and quiet both matter.

  • Best for quiet rooms
  • Strongest air purification
  • Premium residential
  • Best for heating

Those are ACE Climate’s own assessments, not manufacturer claims.

Mitsubishi Electric MSZ-LN black wall-mounted air conditioner installed in a modern living room

MSZ-LN is Mitsubishi Electric's top wall-mounted range. It carries their Plasma Quad filtration, posts some of the highest seasonal efficiency figures in this catalogue, and its smallest unit is among the quietest published here.

Why we fit it

  • Plasma Quad filtration built in — one of only two ranges in this catalogue that carries it, alongside MSZ-RZ.
  • Among the highest seasonal efficiency figures in this catalogue, in both heating and cooling.
  • The three smallest units are rated 19 dB(A), among the quietest figures published in this catalogue.
  • Wi-Fi, app control and voice assistant support as standard.

What to weigh up

  • The filtration and the efficiency are what set this range apart. If neither is the priority, MSZ-AY covers the same rooms.
  • Which finishes are currently offered was not something our research could establish. We confirm it before anything is ordered.
  • That 19 dB(A) belongs to the three smallest units. The 5.0 kW and 6.1 kW models are louder.

Our engineer’s view

Filtration is the reason to choose this one. MSZ-LN and MSZ-RZ are the only two ranges in this catalogue fitted with Plasma Quad, where most of the others rely on mesh and deodorising filters. We have no measured comparison between the filtration systems here, so treat that as a difference in approach rather than a proven margin. It is also among the most efficient and quietest ranges we list. It sits at the top of the M Series and is worth it where filtration and quiet are both priorities — not where the job is simply heating and cooling a room.

Available sizes

Which one suits your room depends on the heat load, not the floor area. A survey decides it; these are what the range offers.

dB(A) is a measurement of sound, and the scale is not a straight line — a drop of 10 dB(A) sounds roughly half as loud. The quietest figure is the lowest fan setting Mitsubishi Electric publishes for that size, not the sound at every speed, and it is measured under their own conditions rather than a shared test. What the numbers mean

Available finishes

These are the finishes Mitsubishi Electric pictures for this range. Which are currently available in the UK is something we confirm with them before anything is ordered.
