Choose the air-to-air system that suits your home

Pretium groups Daikin and Mitsubishi Electric wall units by what you are choosing for. These groups are ours. They are not the manufacturers’ own classes, and they are not a price ladder.

A later group is not a promise of lower running cost, lower noise, more features, or a higher price.

Features checked against UK manufacturer information, October 2026.

Plain English

What the features mean

Removes excess moisture

A dry mode that lowers humidity. On Ururu Sarara this is done without the same change in room temperature. On the other ranges it is ordinary dry operation.

Standard filtration

A dust filter on the air passing through the unit.

Silver allergen filter

An extra filter on the current Comfora, Perfera, Stylish and Emura ranges. It is not the same thing as Flash Streamer.

Flash Streamer

Daikin’s active air treatment, beyond the dust filter. It is not a medical-performance claim.

Plasma Quad Plus

Mitsubishi Electric’s built-in plasma treatment on Premium and Premium Plus. It is not a medical-performance claim.

Plasma Quad Connect

A separate Mitsubishi Electric device that can be added to Classic, Elegance and Zen. It is not fitted unless the quotation includes it.

V-Blocking filter

The filter on current Elegance and Zen models. It is not Plasma Quad.

Occupancy or motion sensing

Detects people and can send airflow elsewhere, or ease off when the room is empty.

Intelligent thermal sensor

On Stylish and Emura, extra sensing that helps direct warm or cool air. These two do not use the same sensor, and neither is the Mitsubishi Electric 3D i-see sensor.

3D i-see

One Mitsubishi Electric sensor on Premium and Premium Plus. It reads occupancy and temperature distribution. It is not two sensors.

App control

The manufacturer’s app, Onecta for Daikin and MELCloud Home for Mitsubishi Electric. It needs the Wi-Fi described for that range, plus your own internet connection.

Fresh air

Outdoor air brought in by the unit. Only Ururu Sarara does this. The other wall units recirculate the air already in the room.

Humidification

Moisture added to a dry room. Only Ururu Sarara does this, and it is separate from dry mode.

Before you choose

Good to know

Warranty

The manufacturer’s warranty, and Pretium’s installation warranty, are shown on the offer you select. The group does not set the manufacturer’s warranty period.

Groups are not cumulative

Balanced Perfera includes sensing and active air treatment that are not standard on Enhanced Zen. A later group does not include everything from an earlier one.

Matched pairs and multi-room

Ururu Sarara and Premium Plus are matched pairs. Classic multi-room systems use the Classic outdoor range. The other ranges connect to their own manufacturer’s multi-room outdoor units, up to the combinations listed for that indoor model.

Installation matters at every group

Room suitability, installation quality and a clear handover matter as much as the unit you choose.

Not sure which suits your room?

Ask Current, our assistant, on the air-to-air page. It can talk through your rooms and priorities, and you decide what goes on your offer.
