I live in an area with not so great air quality and no AC. We have little air filters inside the rooms, but at night we have to let the cool (and dirty) air inside to cool down the house.
I’d like a solution to blow air in while also filtering it - but aside from one Amazon listing and makeshift solutions with zip ties, I haven’t seen great options.
Any recommendations you have?
Maybe you could make a Corsi–Rosenthal Box. They’re pretty easy and cheap. It’s basically just a fan, a filter(s), and some tape.
Though it would be significantly less effective when bringing in outside air than just filtering inside air.
I like the portable AC units, you get AC AND filtering.
Just make sure you get a dual hose version. One hose is air intake, other hose is air exhaust.
$500, 14,000BTU
Edit Apparently automod hates the links Amazon generates in their apps. Had to get un-banned.
Let’s see if it likes the normal Amazon link better:
I have a dual-hose portable AC, because my landlord sucks and won’t install something sensible like a mini-split. My biggest complaint is that the only mode that sucks in outside air relies running the inefficient and expensive AC. I’m in SoCal, so no cheap electricity for me. If I had the option I’d 100% rather install solar, but as a renter that is definitely not an option.
That said if I was purchasing one, I’d buy the one recommended by TheWirecutter. It uses a dual hose-in-hose design and is more power efficient than most models.
A version of that is on sale in the US from Sam’s Club for $375.
Portable AC units suck. Window AC units are far more efficient
Oh, agreed, but some places limit the use of window ACs.
I’ve just bought some HEPA filters and ziptied them to one of those square fans. Works like a charm.
Honestly, I’d just throw a decent furnace filter on the intake side of a box fan. Its cheap, effective , and you can easily replace the filter once it gets too grimy.
