    11.10.2020 | Afloia | Fillo Air Purifier Wins iF DESIGN AWARD 2019

    The latest data provided by the World Health Organization (WHO) shows that 9 out of 10 people breathe air that contains high concentrations of pollutants. The latest estimates show an astonishing 7 million deaths each year due to environmental (outdoor) and indoor air pollution.

    In this case, it is necessary to put air purifier into the list of essential home appliance.

    Air purifiers can absorb, decompose or convert various air pollutants (generally including decoration pollution such as PM2.5, dust, pollen, odor, formaldehyde, bacteria, allergens, etc.) it is an effective media for improving air quality.

    Some FAQs to help you choose the right air purifiers for you.

    • How do I know if I have an indoor air quality problem?
    • Where to Place the Air Purifiers
    • How long should I run my air purifier?
    • What are the different types of AP filters?
    • What does CADR stand for?
    • What does ACH stand for?
    • What does CFM stand for?

    How do I know if I have an indoor air quality problem?

    The EPA(the Environmental Protection Agency) suggests monitoring your health effects after a change in your surroundings. For example, if you have new health problems after moving, remodeling, refurnishing, or a performing pesticide application, this could be an indicator of an indoor air quality problem. Consult your family physician.

    Other sources of indoor air quality problems include: 

    • Pets
    • Pressed-wood products
    • Poor ventilation

    Look for smelly or stuffy air, condensation on walls or windows, or mold growth around your home.

    If you're unsure, contact your local health department to find professionals to help you solve and identify your indoor air quality problems.

    There are also various indoor air quality monitors you can use to check the number of particles in your home's air

    Where to Place the Air Purifiers

    It should be placed in a space where personal activities are more concentrated. It can be bedroom, office etc. Place the air purifier according to where you would stay up for a long time.

    How long should I run my air purifier?

    Theoretically, the air purifier should be on for 24 hours.

    But in fact, when you are not at home during the day, you can open the windows to keep the air clean, which has the same effect as an air purifier.

    Tests show that it is appropriate to turn on the air purifier for 4-5 hours a day, which can effectively reduce the overall consumables cost of the product while keeping the indoor air clean.

    What are the different types of AP filters?


    Air purifiers usually have 3 types of filters: pre-filers, HEPA Filters and carbon filters.


    Pre-filters
    This layer of filter is basically necessary for each air purifier. It is generally made of special polyester fiber material, which looks thin and has a larger mesh port. This layer is mainly to remove hair, fiber fleece, large particles, dandruff, etc.

    HEPA Filters
    This is made from laminated borosilicate microfibers, which is as thin as paper. HEPA filters are mostly white and consist of hundreds of regular folds. A good HEPA filter generally has a filtration efficiency of 99.99% for particles with a diameter of more than 0.3 micrometers. This layer of filter can remove a variety of air pollution components like inhalable particulate matter, cigarette smoke, pollen, etc.

    Carbon Filters
    The carbon filter adopts aluminum, plastic and paper honeycomb with a honeycomb structure as carriers. Compared with the traditional activated carbon filter, it has better aerodynamic performance, smaller bulk density, larger specific surface area, higher adsorption efficiency, and lower wind resistance coefficient.

    Honeycomb activated carbon filter is made of polyurethane foam with powdered activated carbon, of which carbon content is about 35% -50%. It is highly absorbent, which can be used for air purification, removing volatile organic compounds formaldehyde, toluene, hydrogen sulfide, chlorobenzene and other air pollutants.

    This filter layer has low air resistance and low energy consumption that can deodorize and purify the environment under a certain air volume.

    What does CADR stand for?

    This acronym represents an important measurement for air purifiers. CADR stands for Clean Air Delivery Rate. This measurement was developed by the Association of Home Appliance Manufacturers.

    It indicates the volume of filtered air delivered by an air purifier. It is given in three measurements - one for pollen, one for tobacco smoke, and one for dust. The higher the CADR number, the faster the unit filters the air.

    What does ACH stand for?

    ACH stands for Air Changes per Hour. This indicates how frequently the air purifier filters or changes all of the air in a given space per hour. For example, an ACH rating of 6 means that all of the air in your room is thoroughly filtered six times per hour.

    We recommend an ACH of 5 or 6 for healthy indoor air. For individuals with allergies and asthma, an ACH rating of 6 or 8 is best.

    What does CFM stand for?

    CFM stands for cubic feet per minute. This measurement represents how many cubic feet of air move through the unit per minute. This is important when considering which air purifier is right for you. The higher the CFM, the better potential air purification results.

    Keep in mind that CFM can be impacted by a variety of factors, including fan speeds, insulation, air flow in the room, furniture in the room, and the amount of pollutants in the air. However, there is an equation to help you determine an ideal CFM, which can provide help when deciding on air purifiers.

    To find your ideal CFM, calculate the total volume of your space (length x width x height in cubic feet) and divide this number by your desired ACH. Below is a sample equation:

    CFM  

    =

    18 ft x 24 ft x 8 ft
    5 (air exchanges)

    CFM 

    =

    3456
    5

    CFM

    =

    691.2
