• Indoor Air Quality Management

The interest in indoor air quality (IAQ) has increased rapidly during the last couple of years, with the development of the Covid-19 pandemic playing a key role. Even before working from home became the new normal, people were spending more time indoors, and since the beginning of the pandemic, this has expanded further still. Another thing that has happened during the last two years is that more people are spending more time in one place and / or space. In this case, it is the home.  For homes, Hitachi Residential Air Conditioners can help improve indoor thermal comfort by regulating the temperature of spaces. Also, as a standard, most Hitachi Residential Air Conditioners feature Dry Mode which helps remove and reduce excess humidity.

By controlling these two factors alone, indoor thermal comfort can be greatly improved as well as improving indoor air quality. Hitachi PM2.5 Wasabi Air Purifying Filter is a PM 2.5 filter that provides powerful antibacterial (*1), anti-allergen (*2), anti-mold (*3), and deodorizing (*3) properties when combined with the Hitachi Cooling & Heating standard Stainless-Steel Pre-Filter (*4), and can remove up to 99% of the most common bacteria and allergens. Hitachi UV Fresh emits shortwave ultraviolet light onto the Hitachi indoor unit filters from an internal LED, neutralizing 99% (*5) of bacteria trapped, keeping the inside of your unit clean and reducing the possibility of odors forming. Hitachi FrostWash is a technology that minimizes the amount of dust, mold and bacteria on your Hitachi air conditioner’s heat exchanger. Using FrostWash reduces their presence by up to 93% (*6) and it traps the dust and dirt that lands on the heat exchanger by freezing in moisture that’s generated during normal operation. The frost is then thawed and flushed hygienically out of the unit, carrying the dust, mold and bacteria with it. Thanks to this function, up to 99% of viruses are removed when Hitachi FrostWash is used.
