Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at 877-695-2757 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability.

Filter light came on after two weeks

Lisa from Slidell 9/30/2023

Only had this unit for approximately two weeks and it now states that the filter needs to be cleaned. When we checked the filter it was free from dust/debirs. Also I ordered this unit online through Amazon from a third party. The description that they posted stated that the unit was for an 800 square foot room. When I received the unit the box stated it was for a 700 square foot room.
