There are a few options when it comes to the air purification in your home. Below are some options we offer from Lennox that would replace a normal 1″ filter. As long as there is room to cut into your ductwork to add a couple inches to your filter box, you can install one of these.
This system uses a combination of a 5″ filter and a UV light to kill germs and bacteria to a .01 micron level. It also is communicating with the Signature Lennox lines and Icomfort S Thermostat. If you are looking for this high level purification without the communicating aspect, the Pureair is the one to choose (See below tab)
This is the system that would be placed in ductword. A standard unit covers up to roughly 3,000 square feet
AirScrubber Pro 3000
This is the portable option if a house does not have any ductwork. It covers the same amount of space as the Plus and can plug into any outlet.
