A: I don't run this when we leave town. However I've run this 24/7 for a couple of years unless we lose power. Dog & cat in the house. This is still going strong.

A: Thank you for your inquiry. If this unit loses power, it will need to be manually turned back on once the power is restored. Additionally, the pre-filters have a rated life of 3 months of use. Additionally, we do not advise running this unit without any supervision. If you have any other questions, please do not hesitate to contact our consumer relations team by emailing us at SocialSupport@helenoftroy.com. Thank you.

A: Thank you for your inquiry. This unit is made to be run 24 hours a day to provide constant and clean air. Some Honeywell HEPA and AirGenius air purifiers have been 3rd party tested and found to be effective at reducing certain non-harmful virus and bacteria from the air that passes through the filters. Virus reduction claims vary by model and are clearly marked on each package and on HoneywellPluggedIn.com. We have not tested product effectiveness for the COVID-19 virus and therefore do not claim that the product is effective at COVID-19 virus reduction. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at SocialSupport@helenoftroy.com. Thank you.

A: Thank you for your inquiry. Yes, the Honeywell HPA5100W Insight HEPA Air Purifier still captures pollen because the same true HEPA filter is working at all fan speeds. Quiet just moves air more slowly, so it cleans the room more gradually while staying low‑noise. For faster pollen removal, higher settings increase airflow.
