One of the ways to improve the air quality in your home by eliminating airborne viruses errant smells, like cooking odors, is with a device called a Guardiian Air. This particular model plugs in to a standard household outlet, it has built in another pair of outlets, so you are not prevented from continuing to use that outlet for other devices. The unit has a built in fan that allows the unit to do a great job of handling smells and purifying the air in certain problem areas or near bedrooms, when there is not a central air duct system in the home. For homes with air ducts, there is a centrally located unit that can be installed to take care of the whole home from a central location.
