Daikin, the global leader in heating, ventilation and air conditioning solutions, has significantly expanded its portfolio of Quiet Mark certified products, with a series of key solutions now recognised for their industry-leading acoustic performance.

The latest additions include the Daikin Multi+ system, Perfera and Stylish wall-mounted indoor units, and a selection of advanced air purifiers. These join the already certified Daikin Altherma 3 High Temperature (HHT) heat pump, further strengthening Daikin’s position as a leader in quiet, high-performance climate solutions.

The newly certified range, as of 31 March 2026, includes:

Daikin Multi+
Daikin Perfera wall-mounted unit
Daikin Stylish wall-mounted unit
Daikin Air Purifier (MC30YB)
Daikin Air Purifier (MC55VB)
Daikin Air Purifier with humidification (MCK55W)
Daikin Altherma 3 High Temperature (HHT)

Testing for Sound 

Each product has undergone rigorous independent testing by Quiet Mark experts and has been recognised for delivering exceptional acoustic performance, helping to create calm and comfortable indoor environments.

With growing awareness around the impact of noise pollution on health and wellbeing, low sound operation is becoming an increasingly important factor in building design and product specification. Excessive noise has been linked to disrupted sleep, reduced productivity and increased stress levels, reinforcing the need for quieter indoor technologies.

The expansion of Quiet Mark certification across Daikin’s range reflects a continued commitment to designing solutions that balance performance, efficiency and user comfort.

Powerful and Quiet Performance

The Daikin Multi+ system represents a major milestone within this latest certification, combining heating, cooling and hot water from a single outdoor unit. Designed for residential applications where space, efficiency and comfort are critical, the system delivers powerful performance while maintaining exceptionally low noise levels.

Similarly, the Perfera and Stylish wall-mounted units have been recognised for their ability to provide efficient climate control with minimal sound output, making them ideal for living spaces, bedrooms and home offices where acoustic comfort is essential.

The Quiet Mark certification builds on the established credentials of the Daikin Altherma 3 HHT heat pump, which has already been recognised for its whisper-quiet operation alongside its ability to deliver low-carbon heating and hot water.

Hamid Salimi, Residential Product Manager at Daikin said: “We recognise that creating comfortable indoor environments is about more than just temperature, it’s also about sound. Achieving Quiet Mark certification across such a broad range of products demonstrates our commitment to delivering solutions that support both physical comfort and overall wellbeing.

“The addition of Multi+ and our indoor units is particularly significant, as it allows homeowners and specifiers to choose integrated systems that perform efficiently while maintaining an unobtrusive presence within the home.”

Poppy Szkiler, CEO Founder at Quiet Mark said: “Noise is a key factor in how we experience products in our homes. Quiet Mark’s latest YouGov national noise survey released this month shows that more than half of consumers (57%) say independent noise certification would increase their trust when considering a heat pump purchase. This highlights a growing demand for clearer, more reliable guidance when investing in new home technologies; 61% surveyed are concerned about a heat pump’s potential noise output.

Daikin’s Quiet Mark Certification achievement across its current and new heat pump ranges provides trusted third-party expert assurance to consumers and specifiers regarding leading lowest-noise performance.”
