Here, Martin Passingham, product manager for DX at Daikin UK looks at the latest product innovations, which make maintaining a clean ducted air conditioning fi lter a quick, easy and mess-free task.

educing the energy consumption of commercial buildings by selecting the most energy effi cient climate control solution is essential for reducing running costs and environmental impact. Energy effi ciency and environmental factors have signifi cantly infl uenced the direction of the HVAC sector, and has led to the phase out of high Global Warming Potential (GWP) refrigerants. Moving towards low GWP solutions, such as the R32-based Bluevolution range, off ers installers and end users highly effi cient, environmentally friendly systems that are future proofed against upcoming legislation changes. However, it is important to correctly maintain a newly installed system to ensure its effi ciency does not decrease throughout its service life.
Directly related to the effi ciency of an air conditioning system is the level of dirt and debris build-up on its fi lters. Collecting over time, dust, dirt and other contaminants can become trapped on and within the mesh barrier. Cleaning these fi lters to remove any debris is therefore an essential part of on going system maintenance. Reducing overall system effi ciency, a clogged fi lter forces the unit to work harder and according to
Energy.Gov can increase energy consumption by up to 15%. In addition, the overworking of the unit can decrease its lifespan. For internal units, a clogged air fi lter will force fans to

work harder to push air through its less porous structure. Consuming extra energy, this can lead to the premature replacement of the blower motor within the unit. In addition, a dirty fi lter can inadvertently blow air contaminants into the building, decreasing Indoor Air Quality (IAQ). Awareness of IAQ and its potential impacts has increased over recent years, with poor IAQ found to contribute to absenteeism, employee performance and concentration levels as well as negatively impacting upon respiratory conditions such as asthma. It is therefore important that every step is taken to maintain or enhance IAQ, with regularly cleaning climate control system fi lters a simple but eff ective solution. A manual process, cleaning internal air conditioning system fi lters can be a messy and time-consuming task for both end-clients and installers. Removing the system’s fi lter, cleaning and replacing it - as well as cleaning the area that has become dirty due to dust fall - can mean the task can take an hour or more.
For hotel and residential buildings in particular, this can often mean cleaning the fi lter within a bathtub and then re- cleaning the bathroom used.
Considering the time and space required for this - along with the disruption it can cause to the running of a commercial environment – it is unsurprising that fi lter cleaning is a laborious process often rescheduled with other
