Yeah, battery compatibility is a sneaky factor—went through the same thing with DeWalt. As for noise, personally I'd rather deal with a little hum if it means better airflow. Nothing worse than feeling stuffy and trapped during a storm... Glad your inspection stress is over!
Totally agree about airflow being worth a bit of noise. We had a shelter installed last year, and the first time we tested it out during a storm drill, I realized how quickly things can feel cramped and stuffy. Ended up adding a small battery-powered fan—made a huge difference. Glad your inspection went smoothly; it's always such a relief when you know everything's good to go.

Haha, I learned the airflow lesson the hard way too. We got our shelter set up a couple years back, and during the first storm drill, my kids immediately started complaining about the heat and stuffiness. Thought they'd tough it out, but nope... had to improvise with one of those handheld misting fans from Disney World. Felt pretty silly sitting underground with Mickey Mouse keeping us cool, but hey, whatever works, right? Glad your inspection went well—peace of mind is priceless.
We had a similar issue when we first set ours up. I initially focused so much on structural integrity and waterproofing that airflow didn't even cross my mind. First drill, ten minutes in, and it felt like a sauna down there...lesson learned. Ended up installing a couple of small battery-operated fans strategically placed near the vents—made a huge difference in comfort. Funny how it's always the little details you overlook at first that end up mattering most.
Had the exact same realization when I built mine a couple years back. Spent days obsessing over reinforced walls, waterproof seals, and emergency lighting, but ventilation? Barely gave it a second thought. First time we actually used it during a tornado warning, my family and I were sweating buckets within minutes—felt like we'd stepped into a sauna rather than a shelter.
Ended up retrofitting a small solar-powered fan with an external battery backup. It made things way more bearable down there. Funny thing is, now whenever I'm helping clients plan their shelters or safe rooms, ventilation's always one of the first things I mention. It's amazing how often people overlook airflow until they're actually sitting down there wondering why it's so stuffy...
