Air Purifiers

There is a growing awareness of the importance of purified air, especially among those sensitive or allergic to pollutants and dust. Air purifiers vary greatly between models and manufacturers. Before buying an air purifier, here are some features to consider:

  • functionality - different types of technology are used to accomplish different types of purifying. Purifiers are designed to remove smells and odors, remove dust, remove mold and mildew, remove allergens and bacteria, or a combination of these. Make sure the model you pick meets your needs
  • size - units can only clean a fixed volume of air per hour. While larger units can provide a wider area of coverage, furniture and walls can block air flow and diminish a unit's effectiveness. It might be more effective to have a smaller unit in each room than one large unit for several rooms. Smaller units can also be placed on furniture or shelving instead of the floor
  • maintenance - maintaining the unit is important for effective operation; understand the frequency, cost, convenience, and availability of parts required to maintain the unit
  • cost - in addition to the purchase price, consider the ongoing costs of operating the unit; fans consume a lot of electricity, and many purifiers require replaceable filters that can quickly exceed the initial price of the unit
  • noise - especially important if you are placing the unit in your bedroom where fan noise will disturb your sleep

  • automatic timer - so that the unit only runs when you want it to
  • indicator lights - help you know when to cleaning/replacing filters to minimize maintenance while maximizing efficiency
