    Do take note that every air purifier has its capability to cover certain size of space in your living room. Getting the right power air flow can delivery up to 5 air filtration cycle in an hour.

    This will ensure air pollutant such as allergen, dust, pollen, mold, bacteria to be kept in minimum as possible around your home.

    Make sure that you clean the air purifier once the maintenance signal alert you to clean up the pre-filter.

  3. Bedroom Cleaning: It is recommended to wash your bed sheets and pillowcase every two weeks to minimize dust in your room.

    If you are particular to get rid of dust mites, you should wash the bed sheets and cover at 130 degrees and above.

    It is wise to get a anti-dust mite sheets and dust-proof cover to prevent any dust or mites trap in there.

  4. Avoid Humid Area for Bedroom - Avoid your room in humid area such as basement if possible. If you can’t keep the humid down in your bedroom, it is best to use dehumidifier to keep it down 50% if possible because humid can cause serious problems:

    • Molds
    • Higher temperature thus more dust mites
    • Wood furniture deteriorate quickly
    • Metal in your room rust easily
    • Paint or wallpaper produce fumes that might harm your health.
  5. Decrease overstuff on surface area. It is recommended to avoid putting too much object or overstuff on table, furniture or on the floor. That will minimize dust from trapping around it.

    It is important to do cleaning on the furniture surface regularly and it is significant to keep allergen at minimum level.

  6. Keep floors clear from carpets if possible because it will not trap dust on its surface area and beneath it.

    If you can’t, use a great vacuum to do deep cleaning or regular cleaning daily or weekly. A powerful vacuum that uses bristle brush will effectively lift up any dirt and dust in the carpet.

    Wash the rugs regularly besides relying on vacuum to remove stubborn dirt and salt that stuck in the fiber.

  7. Store your shoes in cabinet. Shoes collect dust, allergen and salt from outside, therefore its best to store inside your cabinet. The best is avoid walking into your house with shoes and remove it before you walk into your house if possible.

  8. Microfiber Duster to clean light fixture, fan and blinds. This is a best cleaning material because it has electrostatic charge that attract dust and dirt around it.

  9. Organize your wardrobe is a good idea because they do collect dust very fast. I would recommend you to get a clear containers to store your seasonal clothing to keep it free from dust.

    Moreover all garments will shed fiber and that will cause dust as well.

  10. Choose your furniture wisely.

    You should avoid upholstered furniture in bedroom if possible. If you can’t, make sure you vacuum to clean it regularly to keep it dust free. It is ideal to have furniture made of leather for easy cleaning and no dust or mites can pass through it.

    When selecting sofa or chairs, make sure it is build with raised legs without the whole base covered the floor. This avoid dust and any dirts trapping underneath the chair.

    Other furniture such as cabinet, wardrobe, table it is best to be made of wood, plastic or vinyl for easy wiping.

    Clean your furniture with damp cloth if possible for effectiveness capturing all dust on surface.

  11. Avoid Heavy Curtain and Drapes. If possible, choose the light cotton for easy cleaning and it can be done regularly.

  12. Do not use Duster. Feather dusters will make the situation much worst than before because all the dust will spread around your house with air column and settle else where. It is good idea to use damp cloth to wipe around the surface.

  13. Start cleaning from top to bottom. It is wise to clean up the highest area such as ceiling and following all the way down so that you’ll be able to capture all the dust that falls off earlier.

  14. Beat your cushions and rugs at least once every three months. Your couch and the pillow on it often collect a lot of dust after some time. Everytime you sit on your sofa or walk on the rug, dust will spread to air column.

    Before you beat the cushion or rug, make sure to do it outdoor and use a hard wooden stick to hit it every surface of the cushion to remove as much dust as possible.

  15. Groom your pets. Dogs, or cats sheds their fur all the time and this contribute to dust build up as well. So you should brush them regularly to minimize dander or fur spread around your house. Do take note you should brush them either outdooror in the bathroom so it will be easier to clean.

    Make sure their bedding is washed regularly as well.
