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.

 

Companies Crowd Air Purifier Market as Airpocalypse Hits China

Olans air purifier OLS-K04B 1

At the beginning of Christopher Nolan’s new blockbuster Interstellar, the earth has become an inhabitable dust bowl with lung-choking air. The terrifying dystopia depicted in the movie may cause anxiety in Chinese people, because it’s very similar to what we are experiencing now.

The worsening air quality has sparked a surge in the sales of air purifiers as people desperately try to protect themselves from the smog. The air purifier market size is expected to jump from RMB12 billion (around US$1.93 billion) in 2013 to over RMB20 billion in 2014 and 75 billion in 2015, according to research institute AVC.

The booming market has attracted many companies. Another AVC report noted that the number of domestic air filter manufacturers has soared 450%, from 21 in Q1 2014 to 95 in Q3 in the same year.

DIY your own low cost air purifier

U.S. Eastern time at 3 pm, 7 high school students from the country to showcase the work of the 24 high school students innovation challenge.

It is understood that the Harvard Youth Innovation Challenge is the Harvard China Education Forum for young people to build exhibition platform. From the organizing committee, the former Harvard Chinese Education Forum as educators China peak dialogue, and less related to the education of the students. This new challenge to attract students effectively to Harvard China education forum links to the Chinese to test the creativity of the young people and to the public affairs observation ability.

Beijing Royal School brought by “DIY your own low cost air purifier” display works won the first prize in the contest, get the education experts unanimously affirmed. The students from the city of the increasingly serious environmental pollution in the process of starting, the source of air pollution were analyzed, and jointly developed a reduce the cost of the air purifier, which is characterized by high efficiency, easy manufacture and low cost.

Outdoor Air Purifier Makes Your Wait for the Bus 40% Less Smoggy

China’s campaign to wipe out air pollution reduced the levels of dangerous particulate matter in the air by 11 percent last year, according to the Ministry of Environment. But the country still has a long way to go before the air its citizens breathe every day can be considered healthy. Only eight out of the 74 cities surveyed met basic national air quality standards.

In the meantime, public awareness is rising. Pollution masks are hot commodities and startups making new models for indoor air purifiers are driving prices down. Now, a new invention currently being tested in Hong Kong claims it can reduce air pollution in an open outdoor space by an average of 40 percent (h/t to Techweb).

Under the prototype of the patent-pending system, air is drawn into the system from the inlet located at bottom. The air current then passes through a bag filter, which is effective in removing fine suspended particles (PM10 and PM2.5), before coming out through the Louvre overhead.

Hong Kong has been testing 2 meter-by-3 meter purification station on one of its busiest streets, queen’s Road East in Causeway Bay, since March. Sino Green tells Tech in Asia one unit costs HKD 600,000 (US$77,400 million). (Update: an earlier version of this story referenced the Techweb article that said the project cost US$10 million to develop. Sino Green has informed us that figure is not accurate.)

Air quality at the station can be monitored remotely. Further planned enhancements include smart controllers to manage operating hours more efficiently, solar panels for energy, and a mist cooling system for summer months.

Techweb says the City Air Purification System will be tested at Beijing’s Tsinghua University next. If all goes as expected, it could expand to other mainland cities in the future.

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.

Home air purifier told you what is HVAC?

It is a common misconception to consider the air filter inside a home’s heating, ventilation and air conditioning system (also known as an HVAC) to be the most affordable and effective way of filtering your air. HVAC filters provide minimal filtration of airbone particles and deliver the air in a dispersed manner at a relatively slow rate. For maximum performance of your home HVAC system and to maintain energy efficiency levels, you should replace your filter at least every three months.

HVAC filters come in different MERV ratings. A higher MERV rating means a tighter weave, which removes smaller airborne particles than a filter with a loose weave. However, a higher MERV rating also means the filter creates more resistance to the air flowing through. This can cause more wear on your HVAC’s motor and yield higher energy costs.

HVAC vs HEPA

Even with high quality HVAC filters and frequent filter changes, HVAC air filters are made to trap only large particles in the air, missing small particles and not truly cleaning the air. In addition, since an HVAC system home air purifier delivers either warm or cool air to your home, it is primarily designed to regulate airflow and temperature, rather than to filter airborne particles out of the air. A free-standing air purifier is capable of targeting smaller particles, and an air purifier with a HEPA filter will remove up to 99.97% of allergens, including dust and mold particles. An air purifier can also be used to target specific concerns or specific areas of your home where allergens and other particles are more prevalent, like living rooms and bedrooms.

Home air purifier:why use hepa filter?

Guangzhou Olansi has conducted testing and research on several models of home air purifiers and filters, using a specialty laser particle counter to measure the percentage of particles removed from the air. Here are the key fact you need to know about HEPA technology and its use in air purifier and HVAC filters.

Why HEPA?

High-Efficiency Particulate Air (HEPA) Filters are proven to be the most trusted filter technology on the market. The key to HEPA Filters is its tightly woven composition, making them an effective and safe solution to remove airborne particles that can aggravate:

  • Allergies
  • Athma attacks
  • Chemical sensitivity
  • Settling dust
  • Mold growth
  • Pet-related allergies and odor
  • Smoke odor
  • Illnesses linked to viruses & bacteria
  • Long term respiratory health problems

    How does HEPA work?

    HEPA Material

    HEPA is a flat, pleated sheet composed of millions of microscopic fiberglass threads, forming a complex maze which traps airborne particles.

    Because particles 0.3 microns are the weakest point of the filter’s performance, a filter is only classified as HEPA if it removes 99.97% of particles that are 0.3 microns.

     

    Three types of capture

    Interception

    As particles flow by, they are attracted and stick to nearby HEPA filter fibers.

    Impaction

    Air flows smoothly around filter fibers, but particles collide and get embedded.

    Diffusion

    Microscopic particles move erratically, increasing the likelihood of being captured by interception or impaction.

    How does HEPA compare to HVAC filtration?

    HEPA filters have the highest level of filtering available. Most home HVAC systems are not designed to handle the strain of the high resistance filtering of a HEPA filter, so an HVAC filter with a tight weave may reduce air flow and ultimately lower air quality. HVAC filters come in different MERV ratings,but even the most efficient MERV-rated HVAC filter is less efficient than an HEPA air purifier. If HEPA filtration is required, we recommend an air purifier.
