    Education GOV provides one-off for kindergartens "Ventilation Inspection Service Subsidy" and "Purchase Air Purifier Subsidy Scheme

    The variant virus strain of COVID-19 has recently spread widely in Hong Kong. In view of the weak self-care ability of young children and cases of upper respiratory tract infection from time to time in kindergartens, schools must be vigilant and take precautionary measures.
    In view of the recent severe epidemic situation, in order to ensure that kindergartens adopt proper ventilation measures and have adequate ventilation facilities, kindergartens need to conduct ventilation tests on school premises, and take appropriate measures according to the test results and recommendations.
    If the improvement measures cannot be completed in a short period of time, schools should install air purifiers that meet the relevant specifications as soon as possible to improve the ventilation conditions in the school room as soon as possible. Ventilation testing in kindergartens must be carried out by registered professionals or contractors.
    Kindergartens must conduct ventilation testing and purchase air purifiers as needed.
    Schools are requested to start the relevant work immediately and complete it on or before December 31, 2022, and submit a report on the use of the subsidy to the Education GOV on or before February 28, 2023.

    Funded projects:

    (i) Ventilation Testing Service Subsidy – The Education Bureau will provide all participating kindergartens with a one-off “Ventilation Testing Service Grant” of up to $15,000 to assist kindergartens in procuring professional services to conduct ventilation testing for school premises.

    (ii) Subsidy for purchasing air purifiers – – – Kindergartens with 66 or less half-day students (one full-time student counts as two half-day students) can receive a subsidy of $20,000; kindergartens with 67 or more students can Received a subsidy of $35,000.

    The scope of ventilation testing services should include:

    (i) Relevant professionals should go to the school to check the ventilation condition of the school premises according to the inspection checklist provided by the Education Bureau;

    (ii) Relevant professionals must submit a written test report to the kindergarten. The report must include the inspection content and results; if improvement is needed, specific suggestions should be made; and

    (iii) After the kindergarten has completed the improvement measures (if applicable), issue a certificate confirming that the ventilation conditions have complied with the improvement recommendations in the report.

    Latest Gym/Yoga Class Vaccine Guideline

    健身室STOCK
    Regarding the two newly-added “vaccine bubble” arrangements in the fitness center, if the ventilation standard is reached and the staff and guests receive the same injections, the number of Group Classes can be increased to 12 ppl, and guests do not need to wear masks when exercising.
    The maximum number of training groups or classroom groups is relaxed to 12 ppl
    1. The air exchange rate is more than 6 times per hour or qualified air purification equipment is installed, and the certificate issued by the registered specialized contractor is displayed in a conspicuous place.
    2. Employees have been fully vaccinated, and those who fail to be vaccinated due to health reasons must be tested regularly
    3. Participants wear masks
    4. The groups must be separated by 1.5 meters or separated by partitions
    Customers can avoid wearing masks when exercising
    1. Employees have been fully vaccinated, and those who fail to be vaccinated due to health reasons must be tested regularly
    2. All users have been fully vaccinated
    3. The air exchange rate is more than 6 times per hour or the qualified air purification equipment is installed, and the certificate issued by the registered specialized contractor is displayed in a conspicuous place.
    4. Everyone needs to scan “LeaveHomeSafe APP” before entering the fitness room
    Our HKM team mainly provides anti-epidemic air purification facilities and commercial services for institutions, groups, restaurants, fitness centers, clubs, and nursing homes. In recent months, we have received a lot of inquiries from fitness centers/yoga classes on “meeting FEHD specifications-air purifiers”. Coordination and services have been provided to thousands of venues during the epidemic. Now I will introduce how to choose the most suitable air purifier products for fitness centers:

    Ventilation equipment for catering premises

    The outbreak of the new crown pneumonia has been repeated. Following the spread of restaurant groups, and in order to prevent other restaurants from exploding due to insufficient ventilation, the government gazetted in the early hours of Wednesday morning that food and beverage premises that provide dine-in must comply with the regulations on or before April 30 New regulations for air change or air cleaner equipment. Increase the air exchange rate to at least 6 times per hour, or install qualified air purification equipment to reduce the risk of transmission.
     
    Violators may be fined to stop eating in the evening market and tighten to 2 people per table for a period of 14 days.
    At present, most restaurants have about 3 to 4 air changes per hour
    The more convenient way is to install air purification equipment equipped with “High Efficiency Particulate Air Filtration Technology HEPA”.
    If you fail to achieve 6 air changes, according to government requirements, one of the following conditions must be met:

    1. Install an air purifier, equipped with high-efficiency particulate air filtration technology (HEPA): PM0.3 particle removal rate 99.97% (PURE HEPA) 

    The minimum efficiency of HEPA for filtering particles larger than 0.3 microns from the air should be 99.97% and should comply with European standards BS EN1822-1:2009 to BS EN 1822-5:2009 (EPA, HEPA and ULPA) or other equivalent international standards. /National standard.

    The number of air purification equipment required for the seating area of the catering premises shall be configured in accordance with the seating layout and spacing of the seating area, and comply with the installation guidelines of the relevant manufacturer and the design coverage of the air purification equipment. At the same time, the air purification equipment should be reasonably and evenly distributed in each seating area and individual compartments. Air purification equipment should be regularly maintained in accordance with the manufacturer’s instructions.
    HEPA should be replaced regularly in accordance with the manufacturer’s recommendations, otherwise the HEPA filter should generally be replaced at least once every 3 to 6 months to maintain filtration efficiency.

    2. UV-C disinfection lamp (i.e. UV lamp)

    Q: How to configure a suitable purifier? How many to buy? A: Buy an air conditioner to check the horse count, buy a purifier to check the CADR (purification power)

    Clean Air Delivery Rate (CADR) is a standard established by the American Association of Independent Appliance Manufacturers (AHAM). After certification and verification by an independent laboratory, the air purifier will be manufactured in accordance with the manufacturer’s product declaration, and the purchaser can easily determine which air purifier has better performance than other products based on the CADR.
    CADR measures the efficiency of air purifiers based on the area of the room and the amount of clean air produced per hour. The higher the CADR, the better the performance. After the test is completed, the result will be converted to a value in cubic meters per hour (m3/h). The higher the CADR test result, the better the overall performance of the air purifier to clean indoor air.

    How can I calculate how much CADR purifier my restaurant needs?

    Note: Only the dining area of guests is calculated, that is, kitchens, fire escapes, etc. are not included.

    The calculation of the total cube is the floor area X floor,

    For example: 50M2 dining area, 2.5 meters below the floor, and a total space of 125 cubic meters. The minimum requirement for space purification is to clean the space twice per hour.

    Therefore, the purification power (CADR) needs to be able to process 125 cubic meters X 2 times of air per hour, that is: 250 M3/HR

    (ref: https://reviewsofairpurifiers.com/cadr-calculator/)

     

    CADR is the only recognized air purifier standard and is regarded as a national standard in the United States. It can be used to directly compare top air purifiers. You can use CADR to compare air purifier products consistently. CADR has also been recognized by the U.S. Food and Drug Administration and the U.S. Environmental Protection Agency.

     

    What is "High Efficiency Particulate Air Filtration Technology (HEPA)"

    High-efficiency filter (English: High-Efficiency Particulate Air, that is, high-efficiency air particulate filter, referred to as HEPA) is a kind of equipment used for air purification. Cut the tiny dust contained in the air through the filter. The standard of the filter screen is set by the US Department of Energy. For particles with a particle size of 0.3μm, the filtering effect is about 99.97% or more DOP.
    The high-efficiency filter that meets the government’s standard (H13 grade) can remove particles with a diameter of 0.3 microns (equivalent to 1/200 of the diameter of a hair), and the filtration efficiency needs to reach 99.97%. The filtration efficiency of the common HEPA filter on the market From 85% to 99.995%.

    What is ventilation? How to increase ventilation?

    The main purpose of “ventilation” is to provide fresh or fresh air indoors, dilute and remove pollutants, and discharge odors to ensure indoor air quality. The higher the number of “air changes”, the more effectively the indoor pollutants are diluted. When the fresh air supply is insufficient, an air purification system equipped with HEPA technology can be used to increase the air exchange rate of the space.
