Here's our only air filter in the basement, the pc fan #CRBox. The basement is the same raw square footage as the first floor, and is divided up basically the same way (due to the way prior owners had remodeled the first floor to have an open kitchen, etc). Yes, that is an #AQI of 4. Note that the basement is not particularly air-tight - the windows are leaky and old (we actually have water intrusion through one of them, and ants through another). There's a leaky door.

The first floor has the following #CRBox. However, it also has two Coway Airmega AP-1512HH as well. They are too noisy on high, so they run on medium. However, I'm pretty convinced that the CR box is doing the heavy lifting here. But since we spend more time on the main floor than anywhere else in the house, I wanted extra air cleansing (esp for when kids get sick). That's an AQI of 2. The CO2 monitor shows pretty high CO2 because everything's closed up due to the heat.

@Andres4NY@social.ridetrans.it Great! I have one with 9 Arctic P14s & 4 20x20 Filtretes in my living room. I don’t seem to have posted about it on here, but here’s a similar one from my dad (mine has only foam board to house the fans on top, but he takes this one to activities like church and choir so likes it to be more sturdy-even has a handle!) https://mas.to/@thoughtsofawho/109714729163586259

@Andres4NY@social.ridetrans.it that is very cool. I like the more slim design of this, compared to the giant box fan edition! 🤩👍👍
