The Hyrkan Air Purifiers, which are one of the biggest sellers of air purifiers on Amazon, are now sold out at Kohls Air Purification in Los Angeles.

The company has not officially announced that the store is closing its doors.

Instead, Kohls says that it has reached out to customers who have ordered the product and offered to reship the unit.

Hyrkan is also offering an online coupon code for the air purification unit that expires at 5:59pm PT.

The Air Purify, which has been sold to Kohls for $4,500 since it was launched in 2014, was the biggest seller on Amazon when it was first introduced in 2016.
