Residential air filtration from HRV Australia setting a new standard
HRV Director, Dave Kennedy says that HRV gets regular feedback from
asthmatics and allergy sufferers who have noticed a significant improvement in health
and general well-being along with reductions in associated doctor visits and medical
costs, 'we can't cure asthma and allergies but we can certainly remove many of the
triggers'.
HRV's Air Filter is a hospital-grade, deep pleated, graduated density, electrostatic filter
(0.4 micron). Filter media sourced from Sweden using higher grade European F6 filtration
standards. The filter cartridge is replaced every 18months. The filter has been
independently tested by Scandfilter AB to verify its efficiency.
House-hold Dust Reduction
This achieved two-fold. Firstly the filter traps airborne particles down to 0.4 of a
micron, including dust, vehicle emissions, pollens, mould spores, bacteria and other
allergens.
Secondly, through positively pressurising your home these contaminants have less chance
of entering the home through the open windows and doors. The few contaminants that manage
to enter your home have little chance of settling on surfaces due to the constant air
changes and the good thing is - there are no draughts.
The result means higher air quality for occupants to breathe and less time required to
keep the surfaces of your home clean and more time to do the things you want. Conventional
systems simply recirculate the same stale air around and around with little or no
filtration. This means dust is more prevalent and the air is artificially dried to
the point where occupants often complain of dehydration.
The HRV uses natural air with no artificial heating or cooling and because the air is
filtered, there is significant dust reduction in the house.
Health Benefits
According to the Department of Health and Ageing Healthy Homes Report (2002) Australians
list air quality as one of their highest environmental concerns 'as most of us spend more
than 90% of our lives indoors, it is worth thinking more closely about air quality
especially inside the home (p.3).'
Over our lifetime 60% of our exposure to all toxic airborne particles occurs in our own
home. This level of medical grade filtration as a standard inclusion is unheard of in
Australian domestic applications until this point. The positive pressure system created
by the HRV also minimise's the introduction of these contaminants through the conventional
means of open windows and doors, however occupants can choose to have windows and doors
open and not worry about wasting money as you would with air-conditioning or gas heating.
Fresh air with the windows closed- by introducing several exchanges of fresh air per hour
when the system is in heating or cooling mode, HRV is unique in that it does not recirculate
stale air. 'The ducted air systems we typically use may heat or cool recirculated indoor
air, but don't introduce fresh air from outdoors or attempt to remove pollutants (Healthy
Homes, p.26).
Moisture is one of the catalysts for the breeding of dust mites and mould. The reduction of
moisture by ventilation in your household items simply reduces the habitat and with it the
number one trigger for asthma sufferers along with mould and mildew.
Through a combination of whole home heating and cooling, unparalleled filtration and airflow
performance, both temperature variation and moisture retention are minimised or eliminated
in an HRV home.
