Figuring out which air purification system is right for you can be a difficult task without the right information. There are a few key factors you should be aware of before purchasing a model for your home. Keep these four questions in mind when picking out features for your system.

How much ozone is being emitted?

  • Many air purification systems use an ionization process or an electronic precipitator which causes ozone to be emitted from the device. Ozone is a known lung irritant, so consider if anyone in the house has allergies or asthma, as this feature may negatively effect their health.
  • Systems that generate ozone can also leave pollutant deposits on walls.

Do I want a single room purified or the whole house?

  • If you want the air purified throughout your home, you may want to invest in a whole-house air purification system. While these cost a little more than a single room model, they’re more efficient.
  • Single room systems are compact and require no installation. Most use a HEPA or high efficiency particulate air filter, which needs replacement annually.

Does the model have a servicing indicator?

  • Keeping the air purifier in working order is essential to it’s function, so filters must be cleaned or changed as needed.
  • Many models will have a service light or air quality indicator which lets you know when it is time to change out the filter.

How much noise does the purifier make?

  • Systems that are built into the ducts of your home, like the whole-house system, are practically noise-free, while single room models tend to be louder.
  • Consider whether the purifier has an audible fan unit and where you may be placing the model in your home.
