These filters are made from MERV 14 synthetic material and are designed to capture particulates 0.3 microns in size or larger. Read more about MERV rating here.
Washing of disposable filters is not reccomended as it may affect the filtration effectiveness. To get the most out of your filter packs, separate each filter into a separate plastic bag and number the bags 1-10. Each day use a new filter from a new bag, being careful to wash your hands before inserting the filter. At the end of the day, replace that filter in its designated bag and move on to the next one the next day. Once you reach the final bag, you can start over with the first filter in the initial bag. The best currently available data shows that Covid-19 is not able to survive on plastic beyond 5 days. By using this system, each filter is sealed in plastic for at least 9 days before reuse. For best results, place the packaged filters in direct sunlight as UV radiation seems to also help kill the virus. Each filter should maintain its filtration capability for about 6 months. If the filter shows any signs of physical degrading or wear, please replace as that may affect its effectiveness
