Carbon filters can help remove odors, which air ionizers alone won't do. HEPA filters are great at trapping small particles, so they're a wise idea for allergy sufferers.
Other types of purificationĪ large percentage of air ionizers don't use ionization alone to purify the air in your home. If you're not sure of the size in square feet of the room you want covered, multiply its length in feet by its width in feet to find the square footage. Bear in mind with larger coverage areas that the coverage will only extend into the next room if the door is left open, but the effects will be slightly less than in the room in which the ionizer is located. This is usually somewhere between 50 and 500 square feet. Rather, they have a maximum coverage area, measured in square feet. Key considerations Coverage areaĪir ionizers won't ionize the air in the entirety of your home. The vast majority of air ionizers use an extremely small amount of energy, so you can run them regularly without worrying about hiking up your utility bills too much.
