We purchased our humidifier 01/06/2020. We had maintained the paperwork and manual since we would refer to it to clean it to put it away for the season. This year when we started it, it would not put out the strong mist it had before and finally went to producing no mist. We contacted the website and received an immediate response. We did as they recommended trying to get it to work, which it did for about 15 minutes, then back to no mist. We contacted them again, sent the necessary documentation and we are not being shipped a new one. How wonderful and refreshing to deal with a company so efficient and who stands by their product. One of the reasons for our purchase was the 5 year warranty. We are Pure Enrichment customers forever now! Oh and we love how quiet it is.
