For a couple days in my room, i find that my nose is hurting and bit congested. I try to find out what's causing this. I seem to think these might the suspects. This is in my bathroom. They don't really look like mold to me. I think it looks to dry to be a mold. more like dirt. but i wanted to see the sub opinion on this.

Picked up a file cabinet at an estate sale. It was free!
But when I brought it home and started cleaning it, I found raised black spotting along the sides.

Is it mold?

It’s a metal cabinet manufactured to look like wood. It doesn’t look like a peel and stick surface that I can easily remove.

Any tips on whether it can be cleaned, or suggested to toss, are much appreciated!

I just bought this cat scratch post off Marketplace and didn’t look at the bottom until hours later.

On the dry wall

Shower frame rotted away and left this?

Im in england, birmingham. Im really confused as to what it could be? Google says maybe some yellow trichia slime mold...

How and what do I wash clothing in that were in a moldy environment? I’ve heard you need to wash it 3 times, in white vinegar and then borax, etc. Is this accurate? I’ve also heard washing it in white vinegar once is fine.

What are the best air purifiers?

I need to move out of my current place and some of the items I have stored were in mold. I’m going to get rid of things like my mattress, couch, computer chair—but do I need to get rid of books? Boots? My desk? Where do I draw the line on what to get rid of? None of my belongings have mold on them, and when I was living in mold, I didn’t even realize it. But in brought all of my belongings with me to a new place and I’ve since became sick since I have a lot of other health issues.

I’m pretty sick right now since a recent tick bite when my MCAS went crazy and I’m super sensitive. I know my gut is an issue. I’m too sick to aggressively treat right now so my doctor is trying to stabilize me first. Any advice on what I should be focusing on? Not sure if mold is a main issue right now but had a horrendous reaction when going through a tote of moldy items a week ago.

Any device is appreciated.

Is this mold and is it concerning? I dumped white vinegar on it.

I discovered that a very minor amount of draining water had accidentally been pooling against our house. Location: Southwest

It is mostly growing on wooded areas in my apartment and once you clean it , it will grow again quick

Can anyone tell me what I’m looking at here? More advanced flooring in basement because they have a home theatre there today - it’s put together with layers of plywood, OSD, and wood flooring. Under is neoprene and wood framing - appears to be some sort of peg board helt within a metal frame as well. It’s dry, slightly flaky, but no idea if it’s actually mold? Any thoughts? Desperate and mildly panicked here because this could be our dream home and this is the main red flag… inspector couldn’t say what it was because of the nature of the complicated floor.

I recently bought a magazine overseas, and I knew there was going to be age-related signs because of when this magazine was published. However, when it arrived, the magazine had a lot of stains and I wasnt sure if it is all totally age-related. I learned about foxing and kept researching but its still unclear to me because there are some spots in the photos that i circled that are not reddish-brown and look a bit weird. The staples used seemed to have rusted. Ive kept it in the packet it arrived in and left it on the floor just in case. I appreciate any insight and help!

This is my home. About 4 months ago a contractor installed this wallpaper. It’s been hot all summer. On the other side of this wall there is a utility storage area, but it’s probably 15 degrees cooler than the house. No water pipes inside this wall and it’s very unlikely to have leaks inside. This wall has no insulation. I moved the couch and found this. Considering replacing drywall on both sides and insulating the wall while I’m at it. Proximity to the outlet seemed strange.

Located in NV.

We have been dealing with various leaks/plumbing issues for two years in this apartment, and in 2024 we reported seeing mold under the sink where leaks had been occurring.
Our landlord painted over it and insisted it was mildew and was not a cause for concern. When I asked to get mold testing, my property manager said that she could arrange testing, but if no mold was found we would have to pay for the costs of testing ($1000+). This effectively scared us out of getting testing done, which I feel so stupid about.

Now in 2026, we have significant flooding issues with water coming out of the walls. Yesterday, the plumber pulled out a piece of the wall and found this mold (pictured), the same stuff that my landlord insists is mildew and not a cause for concern (but isn’t mildew a type of mold…?).
I know you can’t tell what type of mold something is from a photo, but is there anything I can do right now/any advice anybody has for determining if this is “toxic” black mold OR mildew? If it’s toxic, I want to find a place to stay for the foreseeable future as this is being worked on, but that’s a lot of $$ in hotel stays and I don’t want to overreact.

The plumber also found this type of mold in several other places (including all around and behind the dishwasher) and said the water/flooding is all underneath the kitchen floorboards. He said we would at minimum likely need the entire floor replaced, as well as the wall where the leak/water is coming from. They still do not know what is causing the leak; it may be a connecting unit, but the cause is unknown at this point.

I feel paralyzed with uncertainty and don’t even know where to begin. I should get mold testing done, right?
Is this a cause for concern or am I being dramatic? In finding this sub, it seems the moisture and flooding is concerning and obviously must be addressed.
How does one get mold testing done? What should I be asking of my landlord through this process? Any insight is super appreciated, I am really stressed and have no experience in anything like this.

Hi !
I wanted to help my parents clean their house and when I lifted the mattress I saw this orange “dust” and I was wondering if this looks like mold?
It’s a very old wooden house, not very well insulated and we can find this orange stuff on walls sometimes. This room is only used by me when I come back from traveling (I leave for more than a year each time) and it’s not cleaned as often as it should be. I’ve had allergic reactions in the past thinking it was because of pollen but I’m now thinking this could be the cause behind my allergies.
What do you think? Should I get this cleaned by a professional? Is it really mold?

Thank you
