Air Purifiers

Air purifierDo They Really Work for Mold Problems?

If you suffer from mold allergies or live in a wet climate where you know mold spores are rampant, you may have considered purchasing an air purifier for your home. But do they really work?

If you are looking to help prevent mold growth in your home, purchasing an air purifier might be one of many good options. If you already have a mold growth problem, you’re probably going to need an expert to clean up and remediate the problem before an air purifier will prove beneficial. Air purifiers will not help with molds that have already established residence on a damp surface.

Air purifiers work by filtering out air contaminants, such as pollen, dust, pet dander, smoke, and the tiny microscopic spores (seeds) that can potentially develop into a mold problem if given a moist surface to land on. When you turn on the air purifier, it goes to work cleaning the air of the room. Most are designed to run 24 hours a day so you always have clean air to breathe in.

How do you chose an effective air purifier?

  • HEPA filters are recommended since it filters out more than 99.9% of particles down to .3 microns in size. Molds range from 1-20 microns. HEPA filters are also rated (ex. H10, H12) so the higher the rating, the more effective they are. HEPA filters are also more effective than ultraviolet or ionizer air purifiers.
  • Consider the size of the room you want to purify and chose a unit which will accommodate that size or larger. Choosing the right size unit will help with energy efficiency too. Most are designed to work at 10 watts or less on a low setting so you can run it throughout the day without worrying about your power bill. Typically, the bigger the room it’s designed for, the more power it will use.
  • Experts typically recommend that an air purifier should change out the air of the room twice per hour, while some recommend up to six times per hour (ACH).
  • The Clean Air Recovery Rate (CADR) can also tell you how quickly it can clean a certain particle per minute, for example, pollen is between 25 and 450. Air purifiers above 350 are considered, “excellent” by Consumer Reports, while under 100 is considered, “low”.
  • Air filter replacement cost is another consideration. Some can be cleaned and reused while others need to be replaced.
  • The noise level of the unit while it runs is another consideration. Most are very quiet but make sure you are satisfied with the noise level since it is designed to run 24 hours a day.
