Not sure if it works.
Got 2 units for our 45' motorhome. Was hoping to get rid of my allergies. They run 24/7 for almost a month on low speed. Filter reminder come on, which is supposed to go on after 500 hours. Checked the filters. They look like new. Allergies still there.<br />Would be better to know that the airflow is restricted to notify for filter replacement than 500 hours of use.<br />Time will tell if I get a relief from allergies with this purifiers.
