We refurbish returned and trade in models. They are inspected to be sure they are suitable for this use. We check the body for cracks and failing paint. We test the motors for speed and quick starts. The voltage and amperage of the power supplies is measured. Workers inspects cells for broken wires and bent plates. After all of these steps are completed, we decided whether a unit is a good candidate to become a 2nd life air purifier.
We clean the bodies thoroughly. Any failing paint is touched up. We replace fan motors in most cases. Technicians install new parts needed in power supplies. We clean the filter cells. Units are reassembled carefully. Finally, each product is carefully repacked in new packaging which is made of mostly recycled products.
