When whole house air purifiers are attached to the central air conditioning unit, the air intake and main return openings are designed in order to result in efficient air purification.  Most of these purifiers require that a distance of the air intake and return openings are at least situated about six feet from each other so that the reintake of the clean air into the air purifier is prevented.  The airflow draws air into the air purifier and then released back into the main system so that it could be circulated throughout the entire house.  It is recommended that the HVAC system that runs in tandem with the air purifier should have a fan that is turned on to allow for better air circulation.  These air purifiers that serve entire homes are able to achieve air changes of about two to four times an hour.  Those requiring at least six air changes an hour should think about investing in separate air purifier units in each room.  Homes about 2000 to 4000 square feet big should benefit from having a whole house air purifier.

One other particular advantage that whole house air purifiers have is its relatively quiet functioning.  As there is no separate unit inside the rooms themselves, there is no noise to indicate that an air purifying equipment is running.  Most central air purifiers use a combination of filtration methods that clean out the small allergens and pollutants from the air and reduce particulate levels in the air.  These filtration methods would include a pre-filter, a HEPA filter and a post-filter.  HEPA filters remove particulates as small as .3 microns in size.  In some central air purifiers, however, having a fine HEPA filter could hamper the air movement in the HVAC system.  This is why those filters used in some of these air purifiers for whole houses are only fine enough to filter particulates up to 1 to 1.5 microns big.  HEPA filters remain to be more efficient in cleaning out the allergens and pollutants from the air.  Using other purification methods like ultraviolet germicidal irradiation increases the purification effectivity of central home air purifiers.

The XJ2100 ionic breeze air purifier uses 25 stainless steel needlepoint ionizers to produce and release trillions of negative ions in the air every second.  This alone cuts down the airborne toxic particles by 99.5%.  The metal dust collection plate that is electrostatically-charged attracts the pollutants and traps the particles.  Potentially dangerous airborne particles like algae, bacteria, germs, viruses, mold spores, pet dander and other microorganisms, as well as gaseous pollutants like chemicals, carbon monoxide, and smoke are effectively cleaned out of the air by this purifier.  The XJ 2100 air purifier could run on four control settings.  It could be turned “Hi” to run at full capacity or “Lo” to have it run for a minute, rest for three minutes, and then run the cycle again.  Control settings “Off” turns the unit off, while another “On” or “Off” setting controls how the fan runs.

It is very easy to maintain the XJ2100 air purifier.  The dust collection plate could easily be removed for cleaning.  Just remove the plate and wipe off the accumulated dust every two to four weeks.  The needle points take about at least a month before any cleaning is necessary.  Twice a year of interior cleaning is all that is needed to keep the XJ2100 ionic breeze air purifier running optimally.  Since the integral parts of this air purifier could be removed and cleaned, there are no replacement parts to worry about.  Even the enclosure is durable as it is constructed of environmentally-safe ABS plastic that is free from corrosion.

The XJ2100 is a versatile ionic air purifier.  It could be used in any room up to 500 square feet in size.  It could also double as a car air purifier when you use the 12-volt DC cigarette light adapter that comes with the unit.  For home or office use, the 110-vold wall plug adapter can power the XJ2100.  This air purifier comes in a manageable package weighing a mere 3.2 pounds.  It runs quietly whether the fan is turned on or off.  It is this quiet durability that makes the XJ2100 attractive to most consumers.  The price tag of less than $150 adds to its appeal especially as it has proven to provide years of effective air purifying service.  The unit comes in black or silver to match most interiors.

The use of the Blueair 402 filter enables Blueair air purifiers to provide clean breathable air in most medium-sized indoor environments.  The patented HEPA silent filters are able to capture 99.97% of most airborne allergens and pollutants.  Up to .1 micron particles could effectively be trapped by Blueair’s HEPA silent filters.  This includes pollen, dust mites, pet dander, mold spores, and other allergens.  For air filtration of air containing gas, smoke, and odors, there is a specially designed Blueair SmokeStop filter that could be used.  Both the HEPA silent filters and the SmokeStop filters are easy to use and are made of environmentally friendly materials.  This makes it all the more beneficial for those who have respiratory ailments.  The air filtered by the Blueair 402 air purifier is truly clean and free from any particles that could trigger allergic reaction or cause respiratory attacks.

The HEPA silent filter is made of polypropylene.  This is one of the least harmful chemicals around.  Compared to the usual triclosan-coated paper and glass filter fibers that most air purifier filters are made of, this material is safer and is non-toxic.  The HEPA silent filter could be recycled.  It does not release toxins into the air and produces only carbon dioxide and water when it decomposes.  These filters are also waterproof, making it more resistant to contamination from bacteria and viruses.  The SmokeStop filter, while made of the same material, also contains three pounds of activated coconut shell carbon that is impregnated with Potassium Iodide, Phosphoric Acid, and Potassium Hydroxide in equal amounts.

The Blueair 402 filter measures four inches by ten inches by twenty one inches.  It conveniently weighs three pounds.  Blueair air purifier units are equipped with filter change timers that indicate when the filters are in need of replacing.  The soiled air purifier filter could be replaced by sliding it out of the side compartment and then dropping in the replacement filter.  There are no special tools that are needed.  The side compartment could easily be opened by hand.   These air purifier filters could be ordered online and shipped anywhere in the United States.  Blueair replacement filters are not usually shipped together with the air purifier itself to prevent potential damage due to mishandling.

The IQAir Health Pro Plus Air Purifier comes from a line of IQAir Health Pro air purifiers.  Aside from the common features of air purifiers in this product line, this particular model comes with a HiFlow gas filter that serves to cut down odors and gases in a room.  This gas filter element contains six pounds of activated carbon.  This complements the other filtration systems used in this air purifier model.  Air goes into this air purifier and passes through the pre-filter  and then into the hyper-HEPA filter before it is passed through the V5 cell HiFlow gas and odor filter.  It is because of this combination of filters that this air purifier model is able to produce cleaner air.  The hyper-HEPA filter, for one, could trap smaller particles that other air purifier brands cannot trap.  Its filtration rate far exceeds HEPA standards.  It is, in fact, the first air purifier in the world to pass the EN 1822, the most stringent HEPA filter test in the whole world.  Compared to other HEPA air purifiers, this air purifier model is able to capture about 100 times more dirt particles.  Particles as small as .003 microns could effectively be trapped by this purifier’s fine filters.  The pre-filter alone already screens out about 90% of larger particles in the air.

To prevent air from bypassing the filters, the IQAir HealthPro Plus air purifier has a triple seal design.  It also has an intelligent filter life monitor that tells the user when the filters need to be replaced.  The combination of filtration systems actually prolongs the life of each of filter.  Replacement pre-filters will not likely be needed for about seven to fourteen months.  The hyper-HEPA filter and the V5-cell gas filter, on the other hand, takes about a year or two of usage before it needs to be changed.  Because the filters are not combined in one cartridge, each one could be replaced separately as needed.  Since the pre-filters are able to trap most of the airborne particles, the hyper-HEPA filter and the gas filter are not overworked and therefore last longer.  When the filters need to be replaced, the filter change indicator light turns orange.  The ease by which the filters could be changed – by simply stacking one on top of the other, is considered to be  a plus over other air purifier models.

The IQAir HealthPro Plus air purifier consumes anywhere from 85 to 215 watts of power depending on its control setting.  There are six different settings that users could choose from.  Using the remote control that comes with the air purifier equipment, the control settings could be adjusted from an air flow rate of 40 cubic feet per meter to 240 cubic feet per meter.  This air purifier effectively cleans out the air in a 900-square foot room.  The equipment could also be set on timer control so that it goes on or off at pre-designated times.

To improve air quality indoors, people have invented indoor air purifiers such as the Ionic Breeze Purifier.  Often a family will decide to use air purifiers because one or more members of their household have allergy or respiratory problem and something in the house is triggering their condition.  For example, a wife may be allergic to smoke, and her husband is a smoker.  Or, the family may have adopted a new puppy or kitten and one of the children has asthma.  We are not always ready to part with a chain-smoking spouse, and we certainly don’t want to give up our best friend.   Air purifiers are a great help in these situations.

The Ionic Breeze Purifier is one of the most commonly used brands of air purifier.  Most purifiers use a fan to draw air in and a filter to purify it.   Unfortunately this system causes a lot of noise and requires frequent filter replacement.  Air ionizers offer a convenient alternative: they are quieter and don’t need filters.  Instead they attract airborne dirt and allergens to a charged plate, just as magnet attracts iron.   Aside from being quiet and hassle-free, this purifier is energy-efficient, using only 10 watts of power.  In contrast, a HEPA filter air purifier consumes about 180-250 watts and needs to have its filter replaced often.

However an air purifier is not without possible problems. First, the collector plates must be cleaned often if they aren’t to lose their effectiveness.  Second, those impurities that are charged and attached to walls and appliances can return to the air if not wiped off immediately.  And third, because these devices have no fans, it is argued by some that they can’t purify air more than a few meters away from the unit.  So you may want to use several ionizers.

Another issue raised against the Ionic Breeze Air Purifier is that it leaves small amounts of ozone in the air.  Ozone is a type of gas capable of destroying harmful bacteria and odors.  If you’re going to run the air ionizer constantly, you should be aware of its ozone emission level since ozone can cause breathing problems.

An air ionizer may be good for you if you want more indoor air control but have no serious breathing problems.  Make a comparison of the various types of air purifiers to find the one that suits your needs.

Like other Ionic Breeze models produced by Sharper Image, the Ionic Quadra Air Purifier is an air ionizer.   To understand what this means, let us remember that everything in the world is made up of molecules or atoms bound to one another by attraction.  When a particle is ionized, it means it has lost or gained electrons.  This addition or subtraction of electrons causes the particle to have either a negative charge or a positive charge.  Since opposites attract, a positively charged particle will bind itself to a negatively charged one, and vice versa.

Apply this to air purification and you will get an idea how ionizers clean the air you breathe.  They charge dust, allergens and other pollutants floating in the air, causing them to drop from the air and fall into oppositely charged objects nearby.  Now of course you don’t want that dirt to shower the furniture in your room, so an ionizer has its own “collecting plate” bearing the opposite charge to draw the particles into it.   But it doesn’t catch all of the dirt, so some of it may wind up on your walls, TV set and other charged appliances.

The Ionic Breeze Quadra Air Purifier makes an improvement over previous editions of the Ionic Breeze.   One of the weaknesses of ionic purifiers is that they do nothing to kill germs and other harmful micro-organisms.   Now the Quadra model includes ultraviolet light at 254 nanometers to eliminate these hazards.   Like earlier releases, the Quadra is quiet, energy-efficient and has no air filtration system.

However the Ionic Breeze products are not perfect.  A commonly cited issue is its release of ozone during operation.  If you are concerned about ozone, you might want to consult with your dealer and your physician to be sure it s safe.

Also, when using an ionic purifier, don’t forget that it isn’t a substitute for keeping your house clean.   You should use a vacuum cleaner regularly, keep allergen sources out of the room and clean your air purifier’s plate every two weeks or less.    It is also important to do your research on whatever brands of air purifiers you might be interested in.  Look for independent studies and reviews, and ask your friends, colleagues and relatives what they prefer.

Airborne Particles – These trigger allergic reactions in allergy sufferers, and can irritate normal people’s lungs as well.  Common airborne pollutants are: dust, mold spores, pet fur, plant spores, smoke, pollen, fungi and other tiny particles.

Gases and Smells – Even if you aren’t allergic to pollen or your cat’s fur, you may be sensitive to certain smells.  It could be cigarette smoke, pesticide or the smell of cooking oil.

Volatile Organic Compounds – These are chemical compounds that are a part of various household agents such as paints, adhesives, varnish, disinfectants and even new leather and carpets.   If you’ve ever felt dizzy from being around furniture polish or a newly painted house, this is why.

Micro-organisms – In this category are fungi, bacteria, viruses and other microbes smaller than the eye can see.

An air ionizer such as the Ionic Breeze Air Purifier works by charging particles in the air.  These charged ions combine with the pollutants and allergens in the air and create a (usually) negative charge.  These are, in turn, attracted to a collecting plate that has a positive charge.  If not the plate, the negatively charged particulates will stick to appliances that are positively charged.  The advantage of an ionic air purifier is that it’s quiet and requires no filter replacement.  It can also catch very small particles.  However it has to be cleaned often.  It doesn’t remove bad smells or kill germs but only takes them down from the air.   Users must beware that the Ionic Breeze Air Purifier emits traces of ozone and must follow instructions carefully.

Another common air purifier is the HEPA filter.  It is great for capturing tiny particles like animal dander, pollen and mold spores.  It is ineffective against gases, smells and chemicals.

If your main concern is bad odors, you can use an ozone generator.  Ozone is extremely powerful against bacteria, but may irritate the lungs.

Carbon air filters are quite effective against chemicals, smoke, gases and odors.  But they are useless against allergens like pollen and micro-organisms, so they are often used in conjunction with HEPA filters.

For sensitive environments, one may use UV or ultraviolet light – based purifiers.   The UV rays can kill mold, bacteria and viruses; but without a filter the germs may pass through too quickly.  Also, UV light attracts and kills insects beneficial to man.

The most well-known model of this product line is the ionic breeze quadra silent air purifier. It has been in the market for how many years now and consumers prefer it more than the other air cleaners due to its quietness and design. The device produces a breeze that captures air particles, but barely creates a mechanical sound. Moreover, due to its quietness, this product is lauded by users for being environmentally friendly. This piece of equipment is approximately 2.5 feet tall and comes in a nice-looking appearance that can suit home decors. Since it doesn’t take up much space due to its horizontal position, the unit can be placed in the corners of your rooms.

Just like the usual ionic breeze air cleaner, it does not use a filtering system. It functions without a fan but works on flat stainless steel blades called collector plates which can easily be removed and cleaned with a damp cloth once a week or every two weeks. It is not just environmentally friendly but economically friendly as well. There is no more hassle of having to replace the filter every time and buy a new one. In addition to its economical advantage, the gadget requires only 10 watts a day, unlike the other air purifiers. The low energy utilization absolutely saves money.

There are three ground-breaking technological advancements that make the ionic breeze quadra silent air purifier stand out from the rest of the air filtration system. One is the electrostatic precipitator technology. Its process is backed up by the basic principle ruling ionic air purifiers where electrically charged airborne particles are drawn into the device due to the air flow or noticeable breeze from the metallic plates. Second, the use of ultraviolet germicidal irradiation through a UVC light inside the machine has proven to be very effective in killing germs. The light is measured at a wavelength of 254 nanometers, emitting just about the right amount of energy to destroy the DNA of viruses and bacteria present. Finally, the ionic breeze quadra silent air purifier has a Zenion effect technology that is only true to this equipment. As explained above, this equipment runs on 10 watts a day, allowing for a 24-7 continuous silent operation. Also, the noise level of Zenion effect is absolutely zero, meaning the device functions with no noise at all. These enhanced product features have made the ionic breeze quadra outstanding in the air filtering industry.

The ionic breeze air cleaner is an output of further research on how to develop the ionic air cleaner. This type is different from the latter in that there is no filter used, though it still utilizes a collector plate that gathers the air particles. The cleaner can only accumulate particles into the plate less than 1/8 of an inch away since it doesn’t have a fan or filter at all. But what’s nice about it is that it does not create noise when used since it has no fan to filter the air impurities in the room. It is much smaller in size, making it much more handy and convenient to use. However, because it is small, the plates are easily covered with dust, thus, requiring regular maintenance. If not, it may not properly clean the air either in a small room or open area. It is recommended to check the plates and clean them once every week to keep functioning efficiently.

To better understand how this kind of air purifier works, it is important to know the principle behind it. Researchers and air purifying experts used the property of electrostatic field structured between the two collector plates of the device. When air particles are gathered, the electrostatic field ionizes it causing the air pressure to become low. As a result, an air flow is produced and starts to move between the plates first then progresses into an increasing level of pressure. The air particles which are electrically charged are collected near the metallic plates through the help of the air flow. Imagine an electrically charged plastic object that captures strands of hair; very light substances, small pieces of paper, etc. This is what makes the device very convenient especially in closed spots like our rooms since it is efficient with minute substances present in the air. This is how the ionic breeze air cleaner works.

Just like the classic air purifier or any type of air cleaner, it is not quite easy on the pocket. However, it doesn’t just save you from health problems; it also saves you from hospital bills and medication expenses. Compared to the typical air cleaner, the ionic breeze air cleaner characterizes a definite progress in the air purifying industry. But then again, it is still wise to choose an air cleaner that tailors your needs.
