We’ve all heard the reports of Covid-19 cases on the rise. To give extra help to keep your family safe it may be a good idea to invest in a humidifier. This will make viruses less likely to be inhaled because the humidity prevents them from staying airborne. Keep the humidity level to about 50% indoors. No humidifier? No worries. Place bowls of water near your radiators or boil water on the stove for about 15 minutes to raise humidity levels.
