Introducing the brand new Aprilaire 4200 Media Air Cleaner! The new Aprilaire 4200 filtration system is the first "active" particle filtration system on the market designed to improve upon the gold standard of whole-house filtration, the Space-Gard system. The Aprilaire 4200 media air cleaner is a highly-advanced filtration system that is easier to install and maintain than the Aprilaire / Space-Gard filter cabinet - the new system is the same height as the Space-Gard 2200 and connects with the same duct transitions, but is thinner by 3.25", allowing it to fit in many more applications without extensive duct modification. The 4200 Air Cleaner is easily adaptable o upflow or horizontal duct applications.
