Review on METROVAC Computer/Electronics Duster, 4 inW, 70 cfm, Upgraded 2016 Version by Michael Reynolds

Could have lasted longer but I forgot to clean the filter underneath and it could burn out the motor. This is fantastic and a huge saving compared to buying compressed air! They are strong, heavy and feel incredibly durable. The engine is serious, but again, don't forget to clean the filter on the bottom after each use! I don't see any difference between the main unit and the cheaper white in appearance other than the color and attachments. It has an extra ESD wrist cord and the attachments are ESD marked (the old ones weren't). When I bought my first one, the ESD version wasn't available yet. Glad to have it and well worth the money to have on hand. ESD cleaning your computer is also worth your peace of mind. The fan motor is POWERFUL so clean outside if you can, it can make a HUGE mess! I use it to blow out small fans and filters to extend life a bit (for air purifiers - hey, those filters are expensive!). So not just for computers. Love mine, will replace it as long as they do! Hope that helps!
