While many people bought these items as a preventive measure before the festival of lights and crackers, there has been a significant rise in sales post Diwali as well.

According to Snapdeal, the category has seen an overall three-fold increase in demand this year compared to the same time last year.

“Between pre-Diwali and post-Diwali, we have already seen a seven-fold increase in the number of air purifiers and masks sold on Snapdeal,” it added.

Interestingly, the city-based portal has curated a special store for the category and is expecting a 10-fold surge in orders placed for air purifiers.

Consumers are also opting for air purifiers on the go. Unit sales of car air purifiers in the first 5 days of November was 140 per cent more than that seen in the month of October for the devices on Snapdeal.

The city’s air quality has steadily worsened over the years, a result of pollution from vehicles and industrial emissions.

Apart from atmospheric dust, burning of crop stubble in farms also contributed to the thick cover of hazardous haze that has been shrouding the city for nearly a week.

The air quality have levels of harmful PM 2.5 particles hovering at dangerous levels, something that has been seen in cities like Beijing.
These fine particles less than 2.5 micrometres in diameter are linked to higher rates of chronic bronchitis, lung cancer and heart disease.

People of the Han Dynasty invented the “air purifier” so long, you have seen?

In winter, the haze is becoming increasingly serious, direct harm to our health. But now developed technology, although the haze problem has not been radical, but we can use anti haze masks outdoors, indoors can purify the air using air purifiers, improve air quality to ensure good health.

Then the problem has come, because the ring (air) (gas) (gas) asked (net) problem (chemical) is not only a problem and demand, so the ancient people in the face of air pollution is how to do it?

As early as 2000 years ago during the Han Dynasty, the wisdom of the Chinese has started the production and use of “air purifier“. So, today we will try to understand the people of the Han Dynasty invented the “air purifiers” look like what, what is the working principle.

Lighting is widely used in the Han Dynasty of the animal fat as fuel, not full combustion of carbon particles and combustion ashes with the hot air flow becomes volatile, leading to indoor smoke. In order not to be choked to death, Han people began to study how to purify the indoor air. Thus, people of the Han Dynasty invented long letter lanterns. Wild fish lamp and lamp set lighting, copper cattle! Invented the three lighting tool is the people of the Han Dynasty the air purification, the aesthetic value of the function of “air purifier”

Of course, around the long letter lanterns, lamp and other lamps Yan copper cattle may vary, but generally in the above three, but the work principle of all the same.

Long letter lanterns, lamp and lamp adopts the bull goose “water filter smoke” way to purify the air. It is a long letter palace lantern, or wild fish lamp and copper cattle light, all contain at least “lamp, lampshade, lamp holder, flue flue (long letter lanterns in the palace is the right arm, a smoke channel of wild fish lamp as the flue pipe gooseneck, it is between the first cattle and light box), 5 tank”, other three kinds of lamps are constructed with reasonable design, many components can be disassembled, and the lamp shade can be arbitrary direction of rotation, to adjust the brightness and the illumination angle. When the lights lit. Through the smoke flue into the palace, wild goose fish and bull’s body, by water filtration, containing dissolved, so as to keep indoor air fresh, preventing pollution of oil fume on indoor air.

Although the gap between the three “air purifier ” and now really great, but in the Han Dynasty have practical exquisite invention of such a set of environmental protection and the Arts in a is rare, simply called black technology, have to admire the wisdom of the ancients!

Understanding the Pros and Cons of DIY Air purifier

Impurities in the air are a concern to anyone who wants to avoid respiratory problems, and installing an air purifier as a do it yourself project is an option worth considering. Given the low cost budget required to set up your own air purifier, this option has emerged as one popular option in many poorer cities where majority of the population find such leading air purifier as IQAir to be way too unaffordable.

Some concerns that you may encounter can delay or derail a project, and anticipating what can go wrong helps you find a way around typical problems. By conducting an air purifier review, you can find the best air purifier for your purposes.

So, should you choose to jump into it and start making your own DIY air purifier? Few considerations are important which you might want to ponder a little more before rushing your decision.

What are those considerations? Read on to learn more.

Pros and Cons of DIY Air Purifier

What Air Purification Power Do You Need?

To get the most effective results from your efforts, you need one that can treat the entire interior of your home or one that is suitable for one room. A system that can clean the air in your whole house may require duct-mounted units or several room air purifiers.

Room units may cover a space as small as 80 square feet or as large as 800. The advantage of using a room air purifier is that the cost for one unit is less than that for treating an entire residence. The disadvantage is that it may not remove as many air particles as one that treats a larger area.

So, knowing what kind of air purification efficiency you need is the first thing you need to ask yourself.

Quality of Your DIY Unit

The poor quality of air in some areas of China is notorious, and it poses serious threats to health. Bloomberg Businessweek recently reported on the efforts of aFulbright scholar to design and build an air purifier for his home.

Living in China for a year led him to investigate the components of air purifiers, and his research led to the development of a simple system. The basic components consisted of a HEPA filter and a fan, and he fashioned a Velcro strap to secure them together.

Testing the effectiveness of his invention required an investment in a monitor, but the results were impressive. By strapping the filter to the flat surface of an ordinary fan, he reduced PM.05 levels indoors by nearly 85 percent. Levels of PM 2.5 indoors fell by more than 90 percent.

From the picture and demonstration, constructing your own DIY air purifier appears like such a simple thing. But getting down right to do it yourself is another thing which might be more challenging that it seems.

One thing you want to keep in mind is the quality of your fan. Some fans are more powerful than others and they run on better quality motor. Think about it. How long do you think your fan will last if you have to turn it on 24×7? Does it have enough power to deliver the kind of CADR rate that top-rated air purifiers for smoke removalin the likes of Rabbit Air MinusA2 is able to deliver?

Fighting Childhood Asthma with an Air Purifier

Early detection is the first step in fighting childhood asthma

Does your child experience shortness of breath or irregular breathing? Do you notice a whistling sound when he or she exhales? Does your child have a persistent cough? If so, there is a good chance he or she may be developing asthma, one of the most serious chronic diseases in children and adolescents, affecting nearly nine million children under the age of 18.

According to the American Academy of Allergy, Asthma & Immunology (AAAAI), 50-80% of asthmatics develop symptoms before the age of five. This is why early detection and working with your child’s asthma specialist is important. Untreated asthma can lead to permanent damage to the airways making it difficult to bring the condition under control.

“Children whose immune systems are not fully developed are most at risk for developing asthma,” said Christopher C. Randolph, MD, FAAAI, and Vice-Chair of the AAAAI’s Asthma Diagnosis and Treatment Interest Section. “However, with early detection, the disease is easier to bring under control, improving the quality of life for your child.”

Look, Listen & Learn

There are no clear markers to predict who will develop asthma and who won’t. However, there are clues and symptoms you can look and listen for in your child that may indicate asthma. Ask yourself these questions:

  • Does your child have allergies? The relationship between asthma and allergies is very strong. If your child has allergies, be on the look out for potential signs of childhood asthma.
  • Does your child cough or clear his/her throat often, even when they aren’t sick? This could be constant or just intermittent. Not all children who have the disease exhibit symptoms each and every day.
  • Does he/she wheeze or is there a whistling sound when your child exhales or with upper respiratory infections?
  • Do you notice shortness of breath, rapid or irregular breathing in your child?
  • Does your child complain of chest tightness? A young child may say his/her chest “hurts” or “feels funny.”
  • Does your child seem fatigued? A child might slow down, stop playing or become easily irritated.
  • Does your child have problems sleeping because of nighttime coughing or difficulty breathing?
  • Is there a family history of asthma and/or allergies?

If you answered “yes” to any of these questions and you suspect that your child has asthma, schedule an appointment with an asthma specialist, such as an allergist/immunologist, a physician specially trained to manage and treat asthma and allergies. An allergist/immunologist will work closely with you to create a daily management plan for your child, demonstrate proper medication use, and develop an asthma action plan, which outlines the actions to take if your child’s condition worsens.

Learn

While there is no cure for asthma, complete control of the disease can be obtained with appropriate management and treatment. Learning your child’s asthma triggers and what steps to take to decrease symptoms is an important step to keep your child’s asthma under control. Children whose asthma is properly controlled should be able to participate in regular activities such as attending school every day and playing sports.

 

Italian man’s portable air purifier bedazzles onlookers

Deal with it. That’s the typical mentality most of the Chinese people have every time the air pollution gets worse.

But this Italian young man was apparently not happy about the status quo.

On Wednesday, he was spotted carrying a self-made air purifier, while riding on a bike in Chengdu, Sichuan Province.

According to the man, who called himself Mike, it cost him about 1,500 yuan($245) to build the device, using a home air purifier and attaching an oxygen mask to it.

Moreover, he also installed a storage battery and inverter as power supply.

According to experts, it’s possible to convert room air cleaners into portable air purifiers.

However, even if it’s technically possible to do so, experts say it is quite unlikely to achieve the same effectiveness in air filtering as a good breathing mask can do.

And even in developed countries, where the air quality is much better, an air cleaner needs to exchange the air in a room seven to eight times every hour, in order to maintain desired indoor air quality.

Debate over whether should schools use air purifiers

With the repeat occurrence of smog in China, many parents call for installation of air purifiers in classrooms. Some parents even offered to pay for the purifiers. However it is refused by school authorities. It has caused hot debate over whether air purifiers should enter schools.

Experts say air purifiers on the market are mostly designed for homes or offices. It still needs evaluation to know if it is useful in classrooms. Education authorities in Shanghai said they will coordinate with relating departments and work for a feasible plan.

Meanwhile, reports said a test has been held in a school in Beijing. After using the air purifier, the level of PM 2.5 in the classroom decreased, but with dozens of students in the enclosed room, the dense of CO2 has passed the healthy standards.

Does Home Air Purifiers Really Work?

Does the EPA Advocate the Use of  Home Air Purifiers?

To reduce the contaminants that lower air quality in the home, the Environmental Protection Agency first and foremost recommends minimizing or eliminating the sources of the pollution and increasing ventilation in order to replace bad air with good.

Olans air purifier OLS-K04 1

“[Air purifiers] may help control the levels of airborne particles including those associated with allergens.” – United States Environment Protection Agency (August 2009)

However, there are limitations to how much of each of these you can effectively do. Some pollution sources can be easily dealt with, but others cannot. Opening windows to increase air circulation is not always a convenient option, and as the Association of Home Appliance Manufacturers points out, ventilation is relatively poor in many modern homes, as they were designed to be “energy efficient” by reducing airflow to and from the outdoors as much as possible. The EPA therefore also recommends the use of air purifiers to supplement these other avenues of cleaning indoor air.

Understanding the Limitations of Air Purifiers

It is important to understand and accept the limitations of air purifiers in order to comprehend their usefulness. The EPA emphasizes that air cleaners are not meant to be a substitute for the other two methods of cleaning your home’s air described above. However, in conjunction with them, the EPA says that air purifiers “may help control the levels of airborne particles including those associated with allergens.”

Most air cleaners are not effective at removing unwanted gases, being designed instead to target unhealthy particles floating in the air. Among these particles, the relatively larger ones are often missed by the air cleaner because gravity pulls them to the ground more quickly than smaller particles, keeping them out of the purifier’s reach.

Therefore, no one should ever expect air cleaners alone to have a significant impact onindoor air quality. Nevertheless, a high-quality air cleaner can be used to improve certain aspects the air you breathe in your home, and can be an important part of your overall air-purifying strategy.

The Effectiveness of Air Cleaners

The main function of most air cleaners, therefore, is combating smaller contaminating particles. Research has shown that good air purifiers, even those of the smaller, portable variety, are up to 90% effective in reducing these smaller particles, such as those caused by cat dander and dust mites.

The EPA has certain recommendations regarding the use of portable air purifiers. In order to achieve maximum effectiveness, the portable air cleaner should be placed somewhere away from walls or other obstructions and positioned in such a way that the clean air is blown into open, occupied areas. If there is some specific source of pollution, the purifier should be placed nearby. Such purifiers work far better when all doors and windows of the room in which they are located are closed.

  • Do Air Purifiers Work For Mold Removal? – Partially.  Some air purifiers may effectively remove mold particles from the air but are ineffective against killing mold spores.  Spores are typically resistant even to UV light treatment.  However, if spores become trapped in a filter, this does keep them from proliferating in your home.  Careful and proper disposal of used filters is essential.  We recommend changing filters outside your home to prevent unwanted release of trapped particles and spores.
  • Do Air Purifiers Work For Pet Allergies? – Partially.  Some air purifiers can remove pet hair and dander trapped in the air.  However, heavier pet dander particles often fall out of the air column and settle onto surfaces.  Frequent cleaning is recommended.  Also, keep pets out of sleeping areas to avoid contact with pet dander throughout the night and other sleeping times.
  • Do Air Purifiers Help With Hay Fever?– Depends on the source of your hay fever allergy.  According to the Mayo Clinic, hay fever can be caused by various pollens, fungi and mold spores, dust mites or cockroaches, and pet dander.  Air purifiers range in their effectiveness of cleaning the air of these particles depending on model type.  Air purifiers are most effective at reducing pollen particles in the air column and are recommended by the Mayo Clinic.  Dust mite feces, cockroach body parts and pet dander are typically heavier particles that fall out of the air column and must be cleaned from surfaces.  Use allergen covers on bedding and pillows to protect against the most common exposure to dust mites.  Keep pets out of sleeping areas.  Use HEPA filter equipped vacuums to clean surfaces.

Summary

In conclusion, air purifiers, while not sufficient to deal with all the hazards of indoor air pollution on their own, are a useful tool which should not be overlooked by anyone interested in keeping his or her home’s air as clean as possible. When the air purifier is of good quality and used effectively, it has an important role to play in the fight against the toxins and irritants that infest our inside air.

  • Air purifiers are most effective at removing particles that remain trapped in the air column such as various pollens, dust, and some molds
  • Air purifiers are not very effective with dust mite allergies since these allergens tend to remain on surfaces like pillows, bedding, furniture etc.
  • Air purifiers have mixed results with pet allergens due to these particles not always remaining long enough in the air column to be filtered effectively
  • Air purifiers are one solution to providing healthy indoor air and should be used in conjunction with other methods

Do Air Purifiers Work?

A really common follow up question that we get is “I get what these things do, but do air purifiers work?”

The answer is an unqualified and enthusiastic “Yes”!

Home air purifiers work to relieve many breathing related concerns—allergies, asthma or odors, for example—by dealing with a major source of these problems and replacing your pollutant-filled air with the pure air.

Without an air purifier, your lungs are the air purifier.

In fact, a well-designed and well-built air purifier can be used to effectively trap over 99% of the pollutants in your indoor air: pollutants that would otherwise end up in your nasal passages, throat and lungs. Use of a good air purifier will have a significant impact on your indoor air quality.
