Read the report! Electrostatic electronic air filters are only efficient
for a VERY short period of time! After a small amount of dust covers the
filter cell the dust will then pass right through the cell and put
back into your indoor air environment to BREATHE AGAIN AND REACT TO! You
can hear the dust passing through the filter cell as it snaps and pops
which is the arching of the dust as it hits and passes through the cell.
They have to be washed way to often to continue to operate properly.
Thats way a MUCH cheaper self charging electrostatic filter is a better
idea.

If you really want to keep your home cleaner, purchase quality HEPA air
cleaners and place them in the rooms or open areas that are your main
living spaces. A high quality HEPA air cleaner will exchange the air in
a bedroom area up to 15 times per hour. The cheap department store units
clean an average of 3 or so air exchanges per hour in a bedroom which is
not good enough at all as your A/C or heating system will contaminate
the room fater then the little air cleaner can clean the air.

Also a quality HEPA room air cleaner can do a good job exchanging the
air through their HEPA filters in open spaces up to 1000 square feet.

OZONE---- FORGET it! Unless you have a commercial fire or flood clean up
going on in an unoccupied area! OZONE-Ionizers are only good for smokers
as they quickly knock down the floating smoke and they get rid of the
smoke odors by the next day if operated all night. NO person with
allergies or asthma should have or needs any kind of ozone ionizer at
all! Because they don't filter the air at all and the ionizer will only
drop the dust and allergens ON YOU WHILE YOU SLEEP and on your
furniture! The Only Best Answer Is Owning QUALITY HEPA ROOM Air
Cleaners! Check out http://www.aircleaners.com for the best ones on the

I'm trying to
make sense of this logic. When you vacuum the HEPA filter, you're
pulling the
fine particles away from the filter and spewing it everywhere via
the vacuum
cleaner. I'm sure there's some logic behind it, but it just isn't
all that
obvious right now. Insights are appreciated.
REAL HEPA filters are made from layered spun glass and they should
not be vacuumed. They need to be replaced when full. If you have to
wash the filter your taking the chance of mold or bacteria growth.
Don't trust Honeywell's off the wall claims! Also Honeywell HEPA
air cleaners have a VERY low air exchange rate per hour even in a
small bedroom sized area.

I never like HEPA filters, but they work well in disk drives. For
volume efficiency, use an electrostatic filter. I have used several
whole house
system filters on the furnace/air, and the best are the 3M but also
have lower thermal efficiency. You can also wash many of the fiber
electrostatic air filters, but the cardboard makes it difficult. If
they were made it out of plastic, you could easily clean them.

GS, You may want to read this accurate report on whole house air
cleaner systems to lean why they really don't work well. The Report is
long informative but well worth reading!


Whole House Air Cleaners Report / Why They Do Not Work!
This information, is brought to you by Absolute Air Cleaners and
Purifiers Inc.
As you search for that perfect air cleaner to protect your family from
dust, pet dander and other airborne allergens, you will run across
many different types of air cleaners, air purifiers, air filters and
air filtration systems. One of the most interesting and eye catching
products on the market is the Whole House HEPA Air Cleaner Filtration
System. This report also includes Whole House Air Filters and Whole
House Air Purifiers. There are many of them on the market!

Unfortunately human nature often kicks into high gear when the
wonderful offer of a central whole house air cleaner is advertised as
a way of keeping your entire house clean with just one single gizmo!
THE FACT IS THESE AIR CLEANERS JUST CAN’T CLEAN A WHOLE HOUSE!

There are five types of air cleaning products that are advertised to
clean a whole house.

They a

Whole house HEPA air filtration bypass air cleaners
Whole house Electronic air cleaners
Whole house Self-Charging electrostatic air filters
Whole house Ultra-violet light systems
Whole house Portable ozone-ionizer air purifiers
This report will explain the truth about how each of these products
actually operate and what benefits they really do provide for you.
Also included are the proper steps to take for a clean indoor air
environment.

Myth #1. Whole house HEPA air cleaner / bypass systems - These
somewhat expensive systems are flawed in design from the beginning.
The idea behind these units is to pull a portion of the air stream
from the return side of your furnace or air conditioning system, clean
it and then return it into the supply side of the furnace or air
conditioning systems ductwork. Most of the time, it involves taking up
to 30% of the air from the return ductwork. The air is then cleaned
with a high efficiency filter such as a HEPA and/or carbon filter. The
cleaned air is then returned into the supply ductwork of the air
handling system (bypassing” the air handler unit). Such an air
cleaning system under this design poses many areas of failure. First
of all, you are assuming that the majority of the airborne
contaminants in your living space are drawn into the heating and or
cooling system. However, home heating/air conditioning systems are
designed to heat and cool. They are not designed to pull dust, dander
and allergens into a HEPA air cleaner from the narrow return ductwork
at far distances. Note that the great majority of homes have only one
air return per air conditioning system. So without having a means of
returning the air from each and every room to the air handler, the
overall effectiveness of these HEPA air cleaner systems is nullified.
This is because the majority of rooms will not be able to have dirty
air pulled from them. So the “whole house” air cleaner will only be
able to clean the dirty air that makes it into the return side of the
ductwork. This is a very limited amount! Secondly, in order for the
HEPA air cleaner to work at all, the fan for the HEPA air cleaner and
the fan for the air handler unit must run all of the time. THIS MEANS
HIGH ELECTRIC BILLS! Having both blower units running constantly uses
significantly more electricity than portable systems located in
individual rooms. Lastly, and more importantly, even in an ideal world
where the air from all over the house is making it back into the
return ductwork through multiple air returns, a bypass system is only
cleaning up to 30% of the return air because it is only receiving up
to 30% of the return air. This means, even if the HEPA air cleaner
unit is running at 100% efficiency for all contaminants, only 30% of
the entire air going through the return ductwork is actually being
cleaned. Therefore, when you look at the system as a whole, it is only
30% efficient. Plus the entire air return ductwork from the air vents
in the rooms to the HEPA air cleaner system will become filthy because
the air entering into the return ductwork is not being filtered!

Also, Whole House HEPA Air Cleaner Systems require expensive
pre-filter replacements to protect the even more expensive HEPA
filter! The bottom line here is that Central HEPA air cleaner types
that install into air conditioning / furnace systems cannot properly
clean the air in an entire whole house or building!

Myth #2. Whole house electronic air cleaners (Also Called
Electrostatic precipitators) - Electronic air cleaners are made to fit
into the air return side of the central air conditioning system or
furnace. They can only filter the air that is brought into them from
the air return duct or area that leads to the electronic air cleaner
unit. These units use electrically charged metal or fiber cells that
attract dust particles onto them. Unfortunately this old technology is
outdated and it does not work well! This is because after a light
amount of dust covers the surface of the charged cell grid, the rest
of the incoming dust and allergens will pass right through the air
cleaner and back into the indoor environment for people to breathe!
Also, Central Electronic Air Cleaners with Charged Collector Cell
Grids Produce Non-Adjustable Levels of Ozone! This can be an irritant
to people with asthma and lung problems! Since most homes and
buildings have only one central air return per system or zone, these
electronic air cleaners cannot pull dirty air from rooms or areas that
are more then a few feet away from the air return that is attached to
or leading to the electronic air cleaner. Major companies that produce
these electronic air cleaners are Honeywell, Trion and Aprilaire.
There is THERE IS NO WAY that central electronic air cleaners can pull
the dirty air from across the house or from the inside of bedrooms and
or offices that are away from the central air return area in your home
or building! They Are Not Whole House Air Cleaners!

Myth #3. Whole house self-charging electrostatic air filters -These
air filters are custom made to size to replace your existing throw
away air filters in your furnace or central air conditioning systems
air handler unit or air return. They are made from multiple layers of
poly propylene fiber which allow them to become electrically charged
when air flows through them. They can then grab dust and allergens
onto them like a magnet. These air filters are durable, washable,
reasonably priced and they can last for many years. They are wonderful
for keeping your air conditioning or heating system and ductwork clean
as they can catch and remove very small particles of dust and
allergens from the air in your home or building! However, just like
the less effective throw away filters, self charging electrostatic air
filters can only clean the air from the air handler unit or from the
air return area they are operating from! Self-charging electrostatic
air filters cannot pull the dirty air from across the house or from
the inside of bedrooms and or offices that are away from the central
air return area in your home or building! They Are Not Whole House Air
Filters!

Myth #4. Whole house ultra-violet (UV) light systems for central air
conditioning units - These ultra-violet light systems are installed
into air conditioning systems to kill mold and bacteria. They do not
remove dust, particulates or airborne allergens from the A/C system,
air ducts or from the indoor environment! These units are supposed to
be installed so the ultra-violet lights are shining onto the
evaporator coil on the air return intake side to prevent mold and
bacteria growth on the evaporator coil and surrounding area, yet many
of these units are installed improperly into areas of the air handler
or air plenum where they can not do much good. Beware of UV light
systems that produce ozone! Many of these UV light systems produce
ozone at levels that cannot be controlled! Too much ozone can be an
irritant to people with asthma and lung problems! I have experienced
ozone producing UV light systems that created so much ozone it burned
my eyes and throat. And I do not have asthma or any lung problems at
all! Some of these units are also produced with non-ozone producing UV
bulbs. However please note, if an air conditioning system is clean and
installed properly and it has a high quality self charging
electrostatic or pleated air filter in it to protect the air handler
and evaporator coil from dust, the chance of the evaporator coil and
the rest of the system becoming contaminated with dirt, mold and
bacteria will be greatly reduced. We recommend properly cleaning your
air conditioning system and duct work while installing an upgraded
quality air filter instead of a ultra-violet light system. Please know
that ultra-violet Light units for your air conditioning system are not
whole house air cleaners even though people will claim that they will
keep your entire home clean!

Myth# 5. Whole house Portable Ozone Ionizer air purifiers - Some air
purifiers include both needle point and radio wave ionizers that can
ionize the air in mutable rooms in your home or building. These air
purifiers produce negative ions that are sent into the air. Negative
ions work by attaching themselves to small floating particles in your
indoor air forcing the particles to quickly drop out of suspension and
then down to the ground or onto any surface below. These air purifiers
will drop smoke, dust, pollen and animal dander from the floating
indoor air environment and down to the surface below to be vacuumed.
However if your bedroom is in the area being ionized, floating
particles including allergens can drop onto you while sleeping in bed.
This can cause problems for those with allergies and asthma. Some of
these air purifiers also produce adjustable levels of ozone. Ozone is
that fresh smell that occurs after a thunderstorm when lightning cuts
through the oxygen splitting some of the oxygen in the air into ozone.
Ozone does a wonderful job of removing all kinds of odors such as
smoke odors, musty odors, pet odors, food odors, chemical odors, and
body odors. The ozone works by oxidizing the odors. However, since
ozone is an oxidizer it can be an irritant to those with asthma and
lung disease if turned up to high. So if you or a family member has
asthma or lung problems, ozone –ionizer air purifiers are not for you!
IF YOU’RE A SMOKER THEY REALLY DO A GREAT JOB OF QUICKLY REMOVING
FLOATING CIGARETTE SMOKE, CIGAR SMOKE AND ODORS FROM INDOOR
ENVIRONMENTS. Please remember that these air purifiers do not filter
the air and they are not whole house air cleaners even though people
often claim that they are!

THE ANSWER, What You Can Do For a Clean Indoor Environment

As explained above, there is no one single air cleaner or air purifier
system that will keep your entire home or building dust or allergen
free. If you have a central air conditioning or furnace system in your
home or building and you have the desire to keep it as dust and
allergen free as possible, follow the four steps below for a clean and
healthy indoor environment.

Keep you ducted air conditioning system or furnace clean and install a
quality self charging electrostatic air filter or pleated air filter
in the main air return or air handler unit to keep your system clean
for the future. If you desire to have your air ducts and air handler
unit properly cleaned visit the National Air Duct Cleaners Association
at http://www.nadca.com and interview some of the members in your area
so you can choose the right air duct cleaning company that will best
fit your needs.

Purchase and place a quality HEPA air cleaner or HEPA air purifier in
the most important areas of your home or building that need to be the
most dust or allergy free. Most people place HEPA air cleaners or HEPA
air purifiers in the bedrooms, family room and office area if there is
one. If you have a mold problem in your living space or if you need a
unit that will kill and reduce mold bacteria and viruses, make sure
you purchase a portable HEPA air cleaner or air purifier that includes
a non ozone producing ultra-violet light system. When choosing a
portable HEPA air cleaner or HEPA air purifier it is important to look
for brands and models that are quiet while producing the highest air
exchange rate per hour in any given sized room or area, at the lowest
aftermarket filter replacement cost. We feel that the highest quality
HEPA air cleaners/ air purifiers on the market are made by Austin Air,
TRACS, EZ Air and Bio-Net.

If possible replace all carpeting with ceramic tile or hardwood
floors. {Tile is best} New carpeting is loaded with toxic chemicals
that will outgas for a period of 2-3 years and old carpeting is often
loaded with dust and allergens that include molds, bacteria, dead
skin, animal dander and dust mite allergen. All of these problems are
major triggers for allergies and asthma! If the carpeting must stay,
VACUUM OFTEN! Use a quality HEPA vacuum cleaner that is sealed tight
so the fine dust does not blow back into your indoor environment while
you are vacuuming. Sweeping ceramic tile or hardwood floors is not the
best way to clean as it causes the dust and allergens to fly back into
the air. Vacuuming all surfaces with a quality HEPA vacuum cleaner is
the best way to go. We feel that the Airstorm HEPA vacuum cleaner is
the highest quality HEPA vacuum cleaner on the market.

Un-clutter your living space and keep it Clean. This is very
important! Also get rid of all feather pillows and wash all of your
bedding in HOT water as least once a week to limit dust and Dust Mite
allergen from building up. Dust Mite allergen is very reactive to
people with allergies and asthma. It must be reduced as much as
possible! If you have pets, do not allow them into your bedrooms to
spread their animal dander. Look at your bedrooms as a safe haven to
sleep in if you are allergic to your pet dog or cat. If you do have
pets and follow these four steps, you will have a much better chance
of being able to keep the pets that you love and live with. It is our
hope that this report will be helpful to you in creating a healthy,
clean, more allergy free indoor environment for your family or
workplace employees!

This is a good report, although I think it downplays the quality of a
high voltage electrostatic system. Most, if not all electronic systems
emit some ozone. An Ozone generator emits positive and negative ions
and a negative ion generator emits negative, but can emit positive
charges if designed that way. An ozone generator will not cause
collection of dirt on nearby walls and tables and negative ion
generators do.

If no one is in the house, a whole house system can work to a large
degree, but if one moves about in any room, things get stirred around.

An Ozone generator is great for cleansing a room(s) when no living thing
is there. This can be done in homes and commercial establishments
at night or day depending on the situation. It does not take a long
time for the ozone to dissipate, and will leave a room smelling like
it was bleached.
