Is The Central Air Purifier System Better Than
Individual Room Purifiers
Michelle Winters
If you are trying to be economic, you are best advised to not
try to maintain a central HVAC equipment and a whole house air
purifier simultaneously. Unless you have money to waste, you
had better use those hard earned bucks to get other equipments
for improving the quality of the air in your house.
A HVAC (or rather a Heating Ventilating, Air Conditioning)
system shares your home’s central blower and ductwork. So
unless you keep it squeaky clean and dust free it will sprout
these irritable elements into the very air you breathe. And,
this won’t change even if you add a swanky, pricey upstream
filter system.
Most HVAC air purifiers are fixed before motors and fans in
order to save them (the latter that is) from large granular
stuff. There function therefore is not as an air cleanser. In
fact they are not even equipped to purify your air; they have a
meager 1000 cu. Foot/minute airflow, which is not a good enough
speed to really cleanse your air. The air flow at each of its
duct is only as high powered as a tiny fan!
The air from your whole house system does not blow quite the
same everywhere. It chooses to flow through areas where it
receives the least obstruction. Cool air has an affinity
towards the lower part of the room, and therefore completely
avoids the upper parts, especially the little corners. Wherever
there is a little niche or cubbyhole it deposits dust and dirt.
So entire house might be getting a number of air changes per
hour, ultimately the lower part receives dirty air.
Imagine a flowing river with plunging bank cuts and tiny
rapids. Consider what its speed will be if it is followed by
lazy flats complete with sandbars. This is what your HVAC is
like, full with rapid airflow and all, but ultimately not a
very efficient air cleanser.
As a part of whole house purification system an HVAC blower has
to function all the time. Most HVAC’s used at homes are not
built to be strong enough to pull in the air through the well
shut HEPA filter. Thus it must be ensured that they aren’t over
run and in the process heated overtly. This is, however,
unavoidable incase if your furnace filter is built of
fiberglass and is kept unclean.
Another serious problem with HEPA is their habit of creating
heavy static backpressure. Thus, they cannot be fixed directly
into the regular residential system. To solve this problem
therefore, vendors include an expensive bypass vent circuit and
much stronger secondary purifiers. Most partial bypass systems
are incapable of performing their required functions to the
extent necessary. Therefore dirty air easily flows through the
main duct.
Before buying and fixing a whole house air purifier make sure
the air ducts in your system is cleansed out rigorously.
Given that we are not required to see or hear it regularly, we
tend to bypass all thoughts of our air conditioning systems
completely from our minds. Let’s be objective, obviously a
whole house air cleaner is preferable to a portable air
cleaner. Consider, suppose your portable air cleaner suddenly
starts malfunctioning then you take it to your vendor asap.
This doesn’t come in the way of your house’s heating or cooling
which continues despite the air being unclean. On the other hand
a minor glitch which you probably look beyond in case of a whole
house system becomes a reason for you to run to your vendor in
case of a portable system.
If you want to improve the quality of the air in your house
reasonably try and get rid of all toxic sources. Make sure your
ventilation is channelized plausibly and circulation is truly
possible. Regularly clean your HVAC system, and don’t leave out
any pan duct or coil. Keep replacing your furnace filters with
the latest ones. Also, try and use premium chemical-capable
portable room air-purifiers in your bedrooms.
If you still have money to spare spend it on getting a central
vacuum system for your entire house. This will spit out all the
dirty air in your house right outside. Else get yourself a
quality sealed HEPA filter vacuum cleaner.
With additional money where available, consider installing a
central vacuum system for the whole house, which exhausts 100%
of all dirty air outside. Or choose a quality sealed HEPA
filter vacuum cleaner.
