2020 changed the way we think about our homes, offices, schools, shops and other private or public spaces that we share.

With the development of the COVID-19 pandemic around the world, the way we socialise, work and utilise our free time has had to adapt.

ith the need to take better measures to monitor and improve indoor air quality, Hitachi has taken the steps necessary to ensure that the spaces you live and work in are as healthy as possible. 

One of the most significant changes was more time spent indoors which has led to an increased concern about Indoor Air Quality (IAQ).

There are many factors that contribute to poor IAQ, in enclosed spaces. There are gaseous pollutants and then particulate matter pollutants (PM).

Of the gaseous, one of the main sources is a group known as volatile organic compounds orVOCs, which are gases emitted from many common products. These include: paints, and other solvents, aerosol sprays air fresheners, furnishings and building materials, just to nme a few.

 Proper ventilation is one of the easiest ways to improve IAQ. By opening windows or using an air renewal system, indoor air is diluted with fresh, outdoor air.

Use your air conditioning system to keep humidity levels low and manage indoor temperatures, both of which can elevate the presence of gases and PMs.

Air conditioners also feature specialized filters that can help improve IAQ. Developing technology to promote cleaner and healthier environments is not new to Hitachi Heating & Cooling.

This is a company that specialises in efficient climate control solutions that improve IAQ. Following a few of the technologies featured in Hitachi’s range of air conditioners.

Wasabi Air Purifying Filter is a PM 2.5 filter that provides powerful antibacterial, anti-allergen, anti-mould and deodorising properties when combined with the Hitachi Cooling & Heating standard Stainless Steel Pre-Filter and can remove up to 99 per cent of the most common types of bacteria, particulate matter and allergens, as well as bad odours.

UV Fresh emits shortwave ultraviolet light onto the filters from an internal LED, neutralizing 99 per cent) of bacteria trapped on the filter to keep the inside of your home clean and reduce the risk of odours.

FrostWash minimises the amount of dust, mould and bacteria that build up on your air conditioner’s heat exchanger and reduces their presence inside your household by up to 93 per cent.  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 the unit, carrying the dust, mould and bacteria with it.

Hitachi’s FrostWash technology promotes a healthier indoor experience and keeps unpleasant odours at bay. This is self-cleaning technology that thinks before it acts.

The FrostWash cleaning cycle is automatic, starting after a specific number of operating hours have been accumulated.

To do so, the unit needs to temporarily cease its cooling function -  no one wants their air conditioner to clean itself while in operation.

That's why, before initiating, sensor technology will ensure there are no people present in the room to avoid interruption to the comfort of any occupants.

In the instance that a user wishes to initiate the cycle manually, a simple press of the FrostWash button on the S-Series controller is all that is required.

With the need to take better measures to monitor and improve indoor air quality, Hitachi has taken the steps necessary to ensure that the spaces you live and work in are as healthy as possible.
