In the Core of a Powerful Ionic Breeze Air Purifier : Blueair 402
To ensure that the Blueair 402 HEPA silent air purifier is working at optimal levels, its filters need to be replaced at least every six months. Otherwise, its filtration efficiency will be hampered. The Blueair 402 air purifier is highly recommended for those who have allergies as well as those who suffer from respiratory ailments. This Blueair air purifier combines two types of air purifying techniques for better and cleaner air. The first step is to circulate the air in an ionizing chamber. By releasing charged ions to latch on to the airborne particles drawn into the ionizing chamber, the charged particles are then drawn to the second filtration system which involves the use of air purifier filters. The Blueair 402 filter is specifically designed to fit Blueair 400 series air purifiers.
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.
