Review on Ultra Web Cartridge Filter Wet Pickup by Lisa Ramirez

I'm an engineer so I usually do things like this. I remove the tiles and a thin layer forms a fine dust. I have a decent air quality meter that measures particulates using general purpose bags and a filter. I received 234 at 2.5 µg in a room with a nozzle right at the site. I've switched to high power packs and a filter and now my readings are around 21 at 2.5 mcg. For reference, my house is typically running around 15 to 2.5 mcg on any given day. The combination of filters and bags was amazing.
