Cleaning and Disinfecting Your Home

HVAC, ventilation and filtration

Ventilation and filtration through heating, ventilation, and air conditioning (HVAC) systems can reduce the concentration of the virus that causes COVID-19 (SARS-CoV-2) in the air, reducing the risk of airborne transmission can.

  • Make sure your HVAC filter is properly installed and upgrade the filter to the highest rated filter your system can handle (see your HVAC manual or contact an HVAC professional for details).
  • HVAC systems only filter the air when the fan is running. Let the system fan run longer or continuously. Many systems can be set to operate the fan even when there is no heating or cooling.
  • When used correctly, air purifiers can help reduce air pollutants, including viruses, in homes or confined spaces.
  • Improving ventilation with outside air to improve indoor air quality:
    • If possible, open the windows or screened doors.
    • Open the outside air inlet or the ventilation opening of your window air conditioner during operation.
    • Run a bathroom fan when the bathroom is in use or continuously if possible.
    • Avoid these measures if outdoor air pollution is high or if your home is getting too cold, hot, or humid.
  • With portable ventilation equipment such as fans, care should be taken to ensure that air is blown from one person directly to another to reduce the potential for virus spreading in the air or in the air.
  • Operate your HVAC system with an air purifier or portable air filter and increase ventilation are not enough to protect yourself and your family from COVID-19. Continue to follow other prevention guidelines.
  • Use of ozone generators in occupied rooms is Not recommended. They do not effectively remove viruses, bacteria, mold, or other biological pollutants when operated at concentrations that meet public health standards.

Bedroom and bathroom

  • The person who is sick should stay separated from other people in the home (as much as possible).
  • When you have a separate bedroom and bathroom: Wear disposable gloves and clean the area around the sick person only when necessary, e.g. B. when the area is dirty. This will help limit your contact with the sick person.
  • When you don't have a separate bedroom and bathroom: The sick person should clean and disinfect after each use. If this is not possible, the caregiver should wait as long as possible before cleaning and disinfecting.

  • Wash dishes and cutlery with disposable gloves and hot water: Handle used dishes, cups / glasses or cutlery with gloves. Wash them with soap and hot water or in the dishwasher.
