• Dust Regularly using microfiber cloths or electrostatic dusters to trap dust rather than spread it around

• Dust high touch surfaces like desks, windowsills, bookshelves, and light fixture at least once (1x) a week.

• For dusting, use only school provided products. 

Knowing that textiles and fabrics such as: stuffed animals, curtains, plush rugs, upholstered furniture, and area rugs trap dust and allergens. Objects made of such material should not be used. 

If an area rug is needed, it should be:

• Low-pile carpet

• Vacuumed regularly using HEPA filter

• Cleaned at least annually

• Removed from the classroom for summer break.

• Use textiles and fabric items

• Use thick/high pile (shag style) area rugs that are difficult to clean properly.

• Leave textiles in the classroom during summer months.

• Use foam floor squares or low-pile carpet

• Clean routinely (sweep, vacuum, and wash with damp cloth/mop). 

• Ensure mats dry completely to prevent mold formation.

• Use soaking wet mop to clean flooring (foam or carpet) as excessive water may enter seams and remain under flooring. 

• If excess water sink washing is used, pick up mats to allow them to dry fully prior to replacing on the ground. 

• Use moisture-resistant materials for decorations and storage.

• Use plastic or metal containers for storage -- easier to clean and less likely to attract dust/pests.

• Limit paper and cardboard in the classroom; opt for digital or laminated displays.

• Recycle outdated/unneeded paper and cardboard regularly.

• Limit displays to essential materials; keep them organized and easy to clean.

• Store materials in cabinets with sealed doors, especially paper/fabric items.

• Store books, paper, or other porous materials on the floor — can lead to mold growth.

• Use cardboard boxes for storage — traps moisture, contributes to mold, and attracts pests.

• Store unused paper/clutter in open classroom areas — creates dusty environments that are harder to clean.

• Store classroom items directly on the floor.

• Promote healthy hygiene: regular handwashing, avoid touching face to prevent germ spread.

• Establish a routine cleaning schedule for high-touch surfaces, textiles, rugs, and storage areas.

• Limit volatile organic compounds (VOCs) — choose low-VOC or VOC-free paints, adhesives, and materials.

• 
  

• Limit clutter and overcrowding; keep walkways, windows, and vents unobstructed.

• Limit covered surfaces; keep them smooth and easy to wipe.

• Manage electrical wires to prevent trip hazards.

• Dispose of damaged equipment.

• Inspect cords for fraying or damage.

• Plug items directly into outlets or surge-protected strips.

• Keep the top and front of univents clear.

• Block or place items in front of vents or thermostats.

• Cover too many surfaces with cloth or decorative materials.

• Overload outlets with too many devices.

• Use extension cords as permanent wiring.

• Place items on top of or in front of univents.

• Report leaks, water stains, or moisture promptly.

• Empty dehumidifier daily.

• Keep pathways around desks clear for safety and cleaning.

• Be mindful of potential allergens (plants, foods, cleaning products) and adjust.

• Position air purifiers/dehumidifiers centrally, away from windows/univents.

• Replace filters regularly per manufacturer’s instructions.

• Ignore damp/moist areas, especially hidden spots (behind furniture, around windows, under decorations).

• Overcrowd the classroom with excessive furniture/materials — limits airflow and makes cleaning harder.

• Use air diffusers, fresheners, or fragrances that could worsen indoor air quality.

• Place air purifiers/dehumidifiers on univents or next to open windows.

• Neglect filter maintenance or exceed replacement schedules.
