Air pollution is a serious problem — especially inside your home! The EPA has named indoor air pollution as one of the top 5 environmental risks to public health. The EPA also reports that indoor air can be up to one hundred times more polluted than the air outside. One hundred times! And while you are offered many options — standard 1" furnace filters, portable purifiers and ionizers — there’s only one truly effective solution: an Aprilaire Whole-House Air Cleaner.
