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 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.

In light of these findings which have been publicly disseminated, people have been on the prowl for cleaning devices that may offer convenient help in creating cleaner, healthier dwellings.  Cleaner air in one’s home can significantly change quality of life.  We can definitely agree with that.
Coming to the aid of individuals in removing dust, ash, pet dander, and other allergens that pose health risks to home dwellers are ionic air purifiers. Such modern product technologies require some up-front money, although the healthier products are expected to last longer, require less long-term maintenance, and not increase energy bills. The biggest payoff is expected in the form of better health.  Yet some product brands have lately been subject to some flak as far as living up to its claims of effectively removing dust, dander, and other irritants in enclosed indoor spaces is concerned. Such has been the case with the Quadra Air Purifier, whose undeniable appeal has had many consumers purchasing the product, but generating mixed reactions.

The Quadra Air Purifier is the modern, updated version of antiquated types of air purification systems that have been around for over a hundred years. Believe it or not, scientists have long been working on methods and techniques to address impure air. Nowadays, a blueprint for a healthier home is something most homeowners carefully think out with their architects.  Dust that pervades the home environment, and chemical orders that linger for months may seem tolerable in the short term, but people who are sensitive to toxins stand to feel lousy and suffer impaired health long afterwards.

With the clamor for cleaner air going unabated, companies like Sharper Image have churned out innovations like its Ionic Series air purifiers to do the job of creating a noticeable improvement in air quality in many homes. Sharper Image’s Ionic Breeze Quadra air purifier features the OzoneGuard™ for an added level of air cleaning that instantly converts ozone by-product to oxygen molecules on contact.

Ionic Breeze products come with a removable front grill that features the OzoneGuard™. Since ionic purifiers use collection grids, users need not be troubled with replacement filters.  All that needs to be done is wipe off the grid once or twice a month. Sharper Image encountered a serious challenge when Consumer Reports (basing findings on the industry standard for measuring clean-air delivery rate) ran magazine articles in 2002 which casted doubt on the ability of Ionic Breeze to reduce airborne particles. The company branded the claims as false and malicious and has since come out with product enhancements. The other problem raised by consumers is that when dust particles accumulate in the device, the inner plates of the air purifier tend to quickly lose much of their power to attract more particles.

All hope is not lost, though, and people remain optimistic that there will soon be a system that will address the kinks and help in the proper cleaning and purification of indoor air.

It is small wonder that when a well-designed air purifier wends its way to most online sites and claims to re-circulate cleaner air in fuss-free fashion, many consumers – most of them allergy sufferers — become a rapt audience.

Considering that these new electronic devices seem to be aesthetically suited for most modern contemporary homes today, and given their touted benefits of reducing irritants and other airborne allergens that cause a host of respiratory diseases and impaired overall well-being, the new wave of electronic air cleaners have generated much consumer interest.
A typical air purifier works by magnetically attracting airborne particles like house dust and other pollutants into its metal dust collection plates. Any homemaker will find the maintenance cleaning that follows (wiping the plates clean) a practically easy routine.  When particulates and residues from air sucked in for re-circulation accumulate in the metal dust collection plates after weeks of continuous use, the air purifier may produce a buzzing sound, signaling cleaning time. To wipe the metal dust collection plates clean, you can use a damp cloth. The plates will then have to be dried and re-inserted back in place.
One innovation that promises to clear a room (supposedly up to 500 square feet) of dust & other allergens is the compact Sharper Image Ionic Breeze Tabletop. Its features and specifications sound promising especially for consumers looking to avert the most toxic pitfalls when it comes to furnishing, refurbishing and remodeling their homes.
Ideal for small living spaces, the Ionic Breeze Tabletop air purifier is bruited as a quiet appliance. Moreover, consumers will find that the device has no disposable filters that continually need to be replaced. The product can be easily propped up. It does away with the additional accessories that most people end up purchasing to complement their newly bought appliances or electronic gadgetry. The Tabletop version of the Ionic Breeze line, retailing for around $200, offers two silent air-cleaning speeds to deal with dust and other allergans which are the culprits for a variety of illnesses.
The tabletop version of the Ionic Breeze Air Purifier line is suitable for one’s den or master’s bedroom with a study. It likewise holds an appeal for dormitories as well as corporate boardrooms. This tabletop version actually has two silent air-cleaning speeds.
Probably the critical chink in the armor of Sharper Image, the company which retails the Ionic Breeze line, is being the thumbs-down by the American College of Allergy, Asthma & Immunology for being incapable of cleaning and enhancing air quality. When not cleaned well following constant use, the inner plates are unable to harness their capability to attract more dust particles.

- Operates quietly;
- No need to replace filter indicator;
- Dimensions : Height – 13 inches, Width – 5 inches, Depth – 7.5 inches;
- Weight : 3 lb.

Well, it’s not that complicated as it looks at the first sight. Ionic Breeze is the process that is used to clean the air. Technically speaking  the air purifier has 2 cleaning plates which are electrically charged  when the apparatus is plugged into the electrical network. They charge every molecule of air near the plates with an electric charge and an air  flow is created. Charged particles like smoke, pollen, dust, animal dander, chemicals and odors are captured by the cleaning plates and are kept here until the plates are cleaned. This is usually done one time every 2 weeks and you’ll be surprised how much black guck you must clean off stainless steel plates.

Ionic Breeze Silent Air Purifier has also many advantages compared to the normal Air Purifiers. First it is completely silent even at the maximum setting. There is no fan to make noise. The air flow is circulating because of the ionic breeze process created by the plates. You’ll never be disturbed in your room by his presence. Secondly it is very effective from electrical power consumption point of view . The Ionic Breeze uses just 10 watts of electricity. This means it consumes ten times less electrical power than a simple 100 Watt light bulb burning. You can have a Ionic Breeze Silent Air Purifier in every room and the cost of electricity will not elevate to a single light bulb.
Third, you must not buy every few months new filters like in a normal air purifier which has a Hepa filter. You just clean the plates and you plug in again the Ionic Breeze Silent Air Purifier for fresh new air. No new additional cost needed.

Even if you don’t suffer from seasonal allergies, even if you don’t live in a polluted environment which could cause you troubles you’ll still enjoy the Ionic Breeze Silent Air Purifier. It will make your life more comfortable and enjoyable to your home.
