There are many brands of air purifiers on the market today: which one to choose? Considering things like price, the size of the unit, where the unit will be placed and how much maintenance you want to put into the unit are all considerations to think about. Some of the top brands on the market are IQ Air, Alen, Blueair, Austin Air, Allen Air and Honeywell. Air purifiers are sold at specialty stores like The Sharper Image as well as discount stores like Target or Sears.
Consider the technology you want to use in your purifier. Do you want to ionize your home or do you want to use a HEPA air filter or another type of filtration system? Consider your allergies, or those of your family, and choose the appropriate level of filtration or ionization for your particular needs. If you want to remove odors from household cleaners, cooking odors or pet dander or odor, consider a carbon filter. There are many options; one is right for your needs.
Size, price and other specifics
If you have a large home or space to purify, consider buying numerous, middle of the line air purifiers. That way you can cover more space without spending a lot of money on one purifier that will only purify part of the air in your home. Remember, ions cannot penetrate every room of a home. If you go this route, consider a portable ionizer that can be moved around the home as necessary.
Price, of course, is a big consideration. Larger, higher end purifiers will obviously cost more, but an inexpensive purifier might not do the best job (or in some cases, vice versa!) Because of this, cost is not always the best way to consider what purifier is best for you. Instead, consider the replacement cost. Make sure the filters aren't expensive. Also consider replacement costs for UV bulbs, fans and cartridges, as well as electricity consumption.
