Energy Efficiency, Air Quality, Elegance, and Silence
The discreet and refined design, along with the possibility of connection with multi-split systems, makes this series suitable for any application, whether it's a home, office, or small commercial space. Thanks to accurate component design and advanced technologies, energy efficiency and operating economy reach excellent levels on a seasonal basis.
Environmental Responsibility
Mitsubishi Electric is committed to the environment. By using R32 refrigerant, the units comply with European directives on greenhouse gas reduction and do not damage the ozone layer. Advantages include high energy efficiency, reduced refrigerant quantity, lower environmental impact, and ease of handling as pure gas with low toxicity and flammability.

Extremely Silent and Comfortable
Environmental comfort is also linked to noise levels, which is especially important in bedrooms or studies. The MSZ-AY line ensures an ideal climate year-round with a noise level almost imperceptible to the human ear. The 18 dB(A) achieved by the MSZ-AY (sizes 25 and 35) is quieter than the rustling of leaves in the wind, making the air conditioner virtually inaudible to occupants. Therefore, the MSZ-AY is particularly suitable for domestic environments like bedrooms and living areas, where most of our time is spent.

*Applies to sizes 25 and 35.

More Air Quality for Your Home
Plasma Quad Plus Air Purification System
Even if unseen, our homes contain atmospheric contaminants of various sizes: pollen, mold, viruses and bacteria, dust mites, and dust. Their presence can pose long-term health risks, especially for allergy sufferers.
Diagram Description: Illustrates the Plasma Quad Plus system's effectiveness against airborne particles like bacteria, viruses, allergens, dust, mold, and micro-particles. It shows an electrical field neutralizing contaminants.
Effectiveness:
- ✔️ 99% reduction of viruses, bacteria, and mold in the air.
- ✔️ 99.7% reduction of dust mites and dust.
- ✔️ 98% reduction of allergens (e.g., pollen).
- ✔️ 99% reduction of airborne PM2.5 particles.
*Refers to sizes 25-50.
"Yesterday vs. Today" Air Quality Comparison:
| Bacteria | Virus | Mold | Allergens | Dust | PM 2.5 | |
|---|---|---|---|---|---|---|
| Past (e.g., Plasma Duo) | A+ | A+ | A+++ | A+++ | A++ | A++ |
| Present (Plasma Quad Plus) | A+++ | A+++ | A+++ | A+++ | A+++ | A+++ |
Mitsubishi Electric air conditioning systems with Plasma Quad PLUS filtration are designed to improve the air quality in your home. The Plasma Quad Plus technology eliminates bacteria and viruses using an electric field and a series of electrical discharges through which the air passes into the environment.
Air Quality: Self Clean Function
The new Self Clean function dries the indoor unit after cooling and dehumidification cycles, preventing the formation of mold and odors.
Diagram Description: Compares two states: "WITHOUT SELF CLEAN MODE" where residual humidity promotes mold and odors after shutdown, and "WITH SELF CLEAN MODE" where a micro-ventilation cycle dries the unit completely, keeping the evaporator clean. The "ON" state shows a 25-minute timer.
❌ Without Self Clean Mode: After shutdown, the air conditioner retains small droplets of humidity, favoring the onset of mold and bad odors.
✔️ With Self Clean Mode: After shutting down from cooling or dehumidification mode, the air conditioner activates a micro-ventilation cycle, completely drying any water particles and keeping the evaporator clean.
Reduced Consumption, Greater Savings
Dual Barrier Coating
Dual Barrier Coating is a special double-layer protective coating that prevents dust and impurities from settling on the air conditioner's internal components, even after long periods. During operation, dust and impurities introduced during air conditioning cycles deposit on internal components, especially the battery and fan, increasing the machine's consumption by up to 18%. Dual Barrier Coating is Mitsubishi Electric's technology designed to reduce long-term consumption and eliminate the need for maintenance related to this issue.
- ?️ Prevents dust and impurities from settling on internal components, even after long periods.
- ? Promotes reduced consumption and less required maintenance.
- ? More Advantages: greater air conditioner efficiency over time, reduction of energy waste.
