Tips on Choosing the Best Whole House Air Purifier

  • Make sure that you are choosing a purifier that will clean the air in your whole home. If you are choosing a unit that only cleans an area smaller than your home, you won’t notice results and will likely still see dust and experience allergy symptoms.
  • Decide what filter is best for you. HEPA filters are widely regarded as some of the best in the industry as they capture even the most minute pathogens and particles in the air. Ozone filters are extremely powerful at cleaning the air, but they can be harsh and cause nausea if you’re home while the system is running.
  • Know how loud the unit is. Especially if you’re planning on keeping the unit in your bedroom, you’ll want to make sure it either emits a white noise or is very quiet. Additionally, consider the lights on the unit too. They might keep you up if they are very bright!
