Frequently asked questions about air purifiers for asthma

  • What is better for asthma air purifier or humidifier?
  • Should I have an air purifier in my bedroom?
  • Where's the ideal place to put an air purifier?

      When choosing the right spot for your air purifier, make sure it's not hidden behind furniture or under shelves. Most air purifiers have an intake at the front. It's best to keep this facing the open room. It's important to place it in an open area where it can access all the airborne particles in the room. The more you reduce airborn particles the more an air purifier can help with asthma symptoms.

  • Can air purifiers eliminate dust?

      Yes, most air purifiers feature mechanical filtration systems. A method that captures pollutants. This is done by filters trapping and removing large dust particles from the air. Less dust in the air will help with dust allergies & asthma triggers.
