There are some filters that are very effective at blocking the virus, whereas there are others that provide no protection against the virus. If you have a MERV 8 filter, it will not be able to effectively block the virus. However, filters with a MERV rating of 11 or higher are designed in a way that allows them to block and remove 85-95% of viruses. If you are thinking about getting filters to protect against the virus, contact us today.
