Air purifiers, as the name suggests, clean the air. Once dust, dander and smoke settle onto surfaces, there isn’t much these machines can do to eradicate them. So vacuuming and good old-fashioned dusting are important steps to keep allergens and particulate matter at bay. If you have an HVAC system, changing or even upgrading your system’s air filters can help keep bad air in check. The American Lung Association recommends filters with at least a MERV-13 rating. The association also recommends not burning candles in your home, foregoing air fresheners and opting for homemade cleaning supplies over chemical cleaners.
