Westinghouse 1804 Patented NCCO Technology Portable Air Purifier with True HEPA Filter and NCCO Technology - Removes Bacteria, Viruses, VOCs, Allergens, Dust, Smoke, Odors - Ideal for Airplane, Hotels

This air filter is small enough and quiet enough to take with me to meetings and restaurants. The filter is easy to replace. It is nice to have a choice of colors.

Opened the box just like the last one I purchased to find you must remove plastic from filters per startup instructions I pulled cover off, removed plastic from filter and NCCO and replaced as per instructions. The device powered up with a error double beep. So in reading the documents it sounds like there was an issue with filter installation potentially so removing the cover again I find the NCCO reactor has 2 small pegs that must align with holes in the bottom of the filet asssy. Unfortunately the NCCO reactor I received was severely warped and the pegs were raised just enough to make it not connect. After pulling one of the new NCCO reactors I had on hand at home for this model I found the unit still failed to power up or go beyond the double beep.This will not stand I say to myself as I just paid $70 its going to work.. So after carefully voiding my warranty 😉 I pull this thing apart to find more than one design flaw & one serious fire risk.. I would not recommend this to anyone who doesn't want to gutt it and replace the innards with quality comp. Good luck to those who bought this cheep garbage.

We used this during the pandemic in public spaces and it seemed to work but it stopped working a few days later. We never got around to getting it replaced. Do not have a lot of confidence in this product and would not buy again.
