DIY air quality test just slapped me across the face with how gross my indoor air actually is, and yeah, I’m writing this from my slightly musty living room in suburban Ohio where the windows haven’t been cracked since, uh, March? Like, I always figured my place smelled a little “lived-in,” but plugging in this random $30 air quality monitor off Amazon—because I’m too cheap for the fancy ones—lit up like a Christmas tree on fire. Red bars everywhere. PM2.5 at 87. Seriously? That’s wildfire-level bad, and the closest fire is the pizza I burned last week.
I’m not some eco-warrior, okay? I’m the guy who forgets to take out the trash until the bag rips and onions roll under the fridge. But when that little DIY air quality test gadget started screaming at me, I kinda panicked. Not full-on “call the hazmat team” panic, but enough to open a window and cough dramatically for effect.
Why I Even Bothered with a DIY Air Quality Test in My Crusty Apartment
Look, it started because my eyes were itchy and I blamed the cat—but I don’t have a cat. Then my throat felt like I’d been gargling sandbox. So I ordered this purple plastic air quality monitor that looks like a knockoff Tamagotchi. Plugged it in next to my bed—mistake number one, because bedtime readings are apparently the worst. Woke up to 102 µg/m³ of PM2.5. For reference, the EPA says anything over 35 is “unhealthy for sensitive groups.” I am now a sensitive group. Great.
The Embarrassing Numbers from My DIY Air Quality Test (Spoiler: I Live in a Gas Station)
Here’s the raw, unfiltered data I scribbled on a sticky note at 2 a.m. while stress-eating cereal:
- Kitchen (post-cooking bacon): PM2.5 hit 214. That’s “hazardous.” Like, roll-up-the-windows-at-the-pump hazardous.
- Bathroom (after shower, door closed): Humidity 78%, mold risk flashing. I just stared at the black speckles on the grout and whispered, “We meet again.”
- Living room (vacuumed… last month?): VOCs at 1.2 ppm. Turns out my “lavender vanilla” plug-in isn’t masking anything—it’s adding to the soup.
Anyway, I texted a screenshot to my mom and she replied with the praying hands emoji. That’s when you know it’s bad.
What I (Kinda) Fixed After My DIY Air Quality Test Freakout
I’m not saying I turned into Mr. Clean, but I did some stuff:
- Cracked windows like a maniac. Even when it was 34°F outside. My fingers went numb, but the PM2.5 dropped to 42 in an hour. Worth it.
- Bought a $60 HEPA filter that sounds like a jet engine. Named it “Karen” because it complains constantly but gets results.
- Stopped cooking fish in the microwave. RIP my tilapia era. The VOCs were off the charts—smelled like low tide in my hallway for three days.
- Washed my curtains. Yeah, I didn’t know they were washable either. They came out gray. The water was… brown. I gagged.
Also, I learned that my “cozy” habit of drying clothes on a rack in the bedroom? Straight-up mold farm. DIY air quality test taught me that the hard way when the humidity spiked to 82% and the monitor started beeping like R2-D2 in distress.
The One Mistake I Keep Making (Don’t Judge Me)
I still burn scented candles. I know, I know—the VOCs, the soot, the “you’re literally smoking indoors,” blah blah. But “Pumpkin Marshmallow Dream” smells like childhood and bad decisions, and I’m weak. My air quality monitor hates me for it. We’re in a toxic relationship.
Wait—Is Outdoor Air Worse? (A Quick Reality Check)
Stepped outside with the monitor during rush hour. PM2.5: 28. Inside my apartment after improvements: 38. So yeah, my DIY air quality test confirmed I’m basically hotboxing myself with febreeze and regret. The EPA’s outdoor air quality map for my zip code? “Moderate.” My living room? “Unhealthy.” I win.
Final Thoughts: Your Turn to Run a DIY Air Quality Test (Please Don’t Be Like Me)
If you’re reading this while ignoring the faint mildew smell in your bathroom, just… get the $30 gadget. Link below to the one I used (not sponsored, I swear—though I wish). It’s ugly, it beeps, and it will roast your life choices, but at least you’ll know. My indoor air’s down to the 20s now on good days. Still not “good,” but I can breathe without imagining tiny particles setting up camp in my lungs.
