Finally Beat the Foggy Window Battle This Winter

Interesting perspective. I've been battling foggy windows all winter and honestly hadn't thought much about humidity-controlled extractor fans. I've mostly relied on cracking a window open, but it's getting old (and chilly). The sizing point makes sense though - I've learned the hard way that going cheap usually costs more in the long run. Might just bite the bullet and go for a decent fan... seems worth it if it means no more wiping down windows every morning.

Have you looked into how noisy these humidity-controlled fans get? I'm tempted too, but worried about trading foggy windows for a constant hum... Wonder if there's a sweet spot between power and quiet operation. Might need some digging before committing.

"Wonder if there's a sweet spot between power and quiet operation."

That's exactly what I'm curious about too... Have you checked if manufacturers list decibel ratings for these fans? Might give us a clearer sense of how noisy they actually get in practice.

"Have you checked if manufacturers list decibel ratings for these fans?"

Yeah, most decent brands do list dB ratings, but honestly, take those numbers with a grain of salt. I've found that real-world noise can vary quite a bit depending on how and where you mount the fan. Rubber washers or foam padding between the fan and the frame can make a surprising difference. I recently swapped out a powerful but noisy fan for one slightly less powerful with better mounting - huge improvement in noise without sacrificing much airflow.

Good points about the mounting - made a big difference for me too. A couple other things I've noticed:

- Fan placement matters a lot. I moved mine slightly away from the window frame, and it cut down on vibration noise.
- Sometimes the grille or cover can amplify noise. I swapped out a metal grille for a plastic one, and it was noticeably quieter.
- Also, dust buildup can make fans louder over time... quick clean every few months helps keep things running smooth.

Small tweaks add up!

Fan placement is definitely underrated. I had mine mounted super close to the window frame at first, and it sounded like a tiny helicopter was landing in my bathroom every morning. Moved it just a couple inches away, and suddenly it was whisper quiet. Interesting about the grille though - I always assumed metal would be sturdier and quieter. Might have to experiment with plastic next time I swap one out...

Totally agree about fan placement. Had a similar experience - mine was directly above the shower, and it made a weird humming noise every time steam built up. I shifted it just slightly towards the center of the bathroom ceiling, and suddenly it was way quieter and more effective at clearing moisture. About the grilles though, I've tried both metal and plastic. Honestly, plastic surprised me - it felt flimsy at first, but ended up being quieter overall. Metal seemed to amplify vibrations somehow...go figure.

"Metal seemed to amplify vibrations somehow...go figure."

I've noticed the same issue with metal grilles. A few years back, I installed a metal grille in my own bathroom fan thinking it would last longer. It did - but it also resonated noticeably whenever humidity increased. Switched to a plastic grille, and the noise dropped significantly. My guess is the flexibility of plastic helps absorb those vibrations better, even though it initially feels less durable.

It did - but it also resonated noticeably whenever humidity increased.

Had a similar issue with metal vent covers rattling during winter. Ever tried adding thin foam strips behind the grille edges to dampen vibrations? Worked pretty well for me without swapping to plastic.

Foam strips can help, but I've noticed they sometimes trap moisture behind the grille edges, especially in humid conditions. Had a similar setup once and ended up with minor rust spots after a couple seasons. Switched to silicone bumpers instead - still dampens vibrations, but lets air circulate better. Might be worth considering if humidity's a recurring issue in your place...

Good point about the silicone bumpers - I switched to them last year and noticed a big difference. Couple things I found helpful too:
- Make sure the grille edges are clean and dry before installing anything; trapped dirt or moisture can accelerate rust.
- If you're still seeing condensation, check if your indoor humidity is consistently high. A small dehumidifier or even just cracking a window slightly can help.
Had foam strips before, and yeah...they're decent short-term, but silicone bumpers definitely hold up better long-term.

Good advice on checking humidity levels - I see a lot of folks underestimate how much indoor moisture contributes to window fogging. Silicone bumpers are definitely a step up from foam strips, especially if you're tired of replacing them every season. Another quick tip: if you're noticing stubborn condensation, sometimes just rearranging furniture or curtains to improve airflow around the windows can help a surprising amount. Glad you've found something that works long-term...it's always satisfying when you finally nail down a solution.

"sometimes just rearranging furniture or curtains to improve airflow around the windows can help a surprising amount."

Totally agree with this. You wouldn't believe how many times I've seen heavy drapes practically glued to the glass, trapping moisture like crazy. Another sneaky culprit is blinds - especially those thick wooden ones. They look great, but man, they can block airflow big-time. Swapping them out or even just cracking them open slightly can make a noticeable difference. Glad you finally kicked foggy windows to the curb...it's a small victory, but it feels awesome, doesn't it?

"Another sneaky culprit is blinds - especially those thick wooden ones."

Interesting point about the wooden blinds, but honestly, I've had the opposite experience. My wooden blinds actually seem to help a bit because they don't absorb moisture like fabric curtains do. I think the real issue is how tightly they're closed - if you leave them cracked open slightly, airflow improves noticeably. Still, nothing beats proper window insulation or weather stripping if you're serious about tackling condensation long-term...just my two cents.

Funny you mention airflow - I had these heavy wooden blinds at my old place, and at first, I blamed them for the constant fogging. But one weekend, I left them slightly open by mistake, and surprisingly, the windows stayed clear. Seems like just that tiny gap made a big difference. Still skeptical they're a full solution though...probably more of a band-aid fix compared to proper insulation or weather sealing.

"Seems like just that tiny gap made a big difference."

Yeah, airflow can help a bit, but have you checked your window seals lately? I spent years fiddling with blinds and curtains before realizing the seals were shot... replacing those made way more difference than any gap trick.

Good point about the seals - I overlooked mine for ages too. Also worth checking if your windows have drainage holes at the bottom of the frame. Mine were clogged with dirt and debris, trapping moisture inside and making fogging worse. Cleared them out with an old toothbrush and it made a noticeable difference. Simple fix, but easy to miss...

Good shout on the drainage holes - I didn't even know windows had those until recently. 😂 A few months back, I was convinced my windows were just cheap junk because of all the fogging. Turns out, nope, just years of gunk blocking those tiny holes. Quick scrub with a toothpick and some compressed air, and suddenly my "cheap junk" windows are magically decent again. Who knew windows needed their own plumbing system...?

Haha, windows having their own plumbing is spot on... I had a similar revelation with my sliding patio door track - years of dirt and leaves jammed in there. Ever checked yours? Might be another hidden gunk trap waiting to surprise you.

"Ever checked yours? Might be another hidden gunk trap waiting to surprise you."

You know, I laughed when I read this because I just went through something similar last weekend. Decided on a whim to clean out my patio door track...and oh boy, the stuff I found in there was like an archaeological dig. Leaves, dirt, random twigs, even a Lego piece - I don't even have kids! Makes me wonder how long it's been since the previous owner gave it a good clean.

But honestly, it's pretty satisfying once it's all cleared out. The door slides so smoothly now - feels like a new installation. It's funny how these little things around the house can make such a noticeable difference. Now you've got me eyeing my windows suspiciously again... guess I know what I'll be doing this weekend.
