Spent $300 on a radon fan and it dropped my shelter levels by half
I finally bit the bullet and installed a radon mitigation fan in my basement bunker last month. The whole setup cost me about $300 for the fan and piping from the local hardware store. My buddy who does HVAC told me I was an idiot for not testing first, so I grabbed a $15 home test kit. Levels inside the shelter were at 6.5 pCi/L before, which is way over the EPA limit. After running the fan for a week, it dropped to 2.1. Anyone else deal with radon in their underground setups?

Right there with you, the drop in those numbers is a huge relief to see on the test kit. @the_piper is totally on the money about the variable speed controller too, I added one and it made the whole setup way more tolerable at night lol.

A neighbor of mine had a similar problem a few years back with his underground storm shelter. He spent almost $500 on a professional setup because he was afraid to do it himself. After a month his levels went from 8.0 down to 1.5 or so. He told me the fan noise was annoying at first but he got used to it pretty quick.

Double down on the noise issue though, @the_tessa. I ran my fan for about a week straight and the hum kinda faded into the background for me too, but the real trick was getting a variable speed controller. Let me dial it back at night when radon levels drop, so it's barely a whisper. Your neighbor probably would have saved half that $500 just by picking up a good digital meter and a quieter inline fan from a hydroponics shop instead of the fancy radon company markup.
