Key Points

• The weekend away thing that everyone recommends is not actually long enough to work, and there’s a study that says so
• Most of what your place smells like is coming out of soft things, not floating around in the air
• The coffee beans at the perfume counter have been tested and they do nothing

You have no idea what your house smells like.

Not the good version or the awful version, just… yours. That specific thing a friend picks up in the first two seconds at your door.

And your place definitely has one, every place does, mine included. I only found out what mine was because I asked somebody.

So this is how you find out.

A few of these take three days, and one of them takes about thirty seconds, and a couple are things I had wrong for years.

So with that said, here are 12 ways to work out what your home smells like to everyone who isn’t you.

 

 The Basics 

Your Nose Didn’t Break, It Just Stopped Reporting

Two things happen when you smell something, and they’re separate.

The first one is right up in your nose. Those receptors keep getting hit with the same smell over and over, and they stop firing as hard, so you lose sensitivity to that one thing. That’s adaptation.

The second one happens further back in your brain. Your brain decides the smell isn’t news anymore and quits passing it along to you at all, and that’s habituation.

Pamela Dalton at the Monell Chemical Senses Center wrote this up in Chemical Senses back in 2000, and the part that matters for you is that both of them are SPECIFIC.

You don’t go nose-blind in general. You go nose-blind to one thing.

That’s how you can smell your neighbor’s cooking through the hallway with no problem, but then walk into your own place and get absolutely nothing.

So your brain isn’t being lazy about your house. It’s decluttering.

 The Ideas 

Here are the 12 ways to finally find out what your place smells like!!

1Leave for Longer Than a Weekend

This one is very surprising, and it’s probably something you have been doing wrong for years (no offence!). 

Everyone says go away for a weekend and you’ll smell your house when you walk back in. And you sort of will!

But Dalton and Wysocki ran a study where people lived with one specific smell in their own homes for two weeks, and afterward their noses were measurably worse at picking that smell up.

This is the bit that got me. For most of them the dip was still there up to two weeks after the smell was gone.

Two weeks after. Not two days.

So a Friday-to-Sunday trip gives you a pretty small window, and it shuts fast, three or four nights away is where you start getting something real.

Here’s What to Do:

• Next time you’re gone three nights or more, decide before you go that you’re paying attention on the way back in
• Stand in the entryway for a second before you put your bags down anywhere
• Don’t open a window or light anything yet, just breathe normally for about ten seconds

Best move: Go in ahead of whoever you’re traveling with. Talking to somebody pulls your attention off it completely.

2Smell your own arm

The coffee beans on every perfume counter are there for people to sniff in order to “clear” or “reset” their noses before testing new fragrances.

That isn’t what they do.

Alexis Grosofsky and two other college students at Beloit College tried this method. They found no difference in how much fragrance was detected when using the coffee beans versus simply breathing in plain air.

It seems logical. A strong-smelling substance like coffee adds to the smells in the air rather than clearing or removing them from your senses.

Perfume makers use a different approach. Perfumes test their own body scent (usually from the inner elbow area) in order to provide a reference point for comparison.

Here’s What to Do:

• Push your sleeve up and put your nose in the crook of your elbow for a few seconds
• Breathe normally, you’re not hunting for anything
• Then go and smell the thing or room in your home you were trying to smell in the first place

Best move: Use bare skin with no lotion or perfume on it. Otherwise, you’re just smelling your body wash.

 

3Ask One Person, and Ask Them Properly

It’s all about the way you ask that determines the answer you get.

If you say “does my house smell?” they will say no. Every single time. There’s no version of that question a normal, polite person answers honestly, because “yes” sounds like an insult, and they’re not going to hand you one.

So you take the insult off the table first.

What you say instead is, “I’ve gone nose-blind to this place. What does it smell like when you walk in?” Not good or bad. Just what?

That’s a completely different question, and people are surprisingly good at describing a smell once you’ve let them off the hook.

And it’s worth doing, because self-reporting on your own nose is genuinely unreliable.

In one large US study of older adults, 12.4% said their sense of smell was fair or poor, but 22% actually had measurable trouble, and 74.2% of those with measured trouble had no idea.

Ask just ONE person, not a group. The first answer in a group sets the tone, and everybody else just agrees with it.

Here’s What to Do:

• Pick somebody who doesn’t come over constantly (a regular visitor is already adapted to your place too!!)
• Text them beforehand so they know to notice on the way in
• Ask what, never whether

Best move: Get the answer before they take their coat off. They’ll be adapted to your living room within a minute or two of standing in it.

4Check the Couch Before You Check the Room

Most of us go looking for a smell in the air, but the air isn’t really where it lives.

Fabric is. Your couch, the curtains, that rug, the pile of coats by the door.

There’s proper research on this now. Textiles pull odor molecules in and then let them back out slowly, which is why the sofa in a small apartment ends up being the loudest thing in the room. How much a fabric holds depends on what it’s made of, and older work found the amount going up roughly in step with how much moisture is in the fibre. Damp fabric holds more.

So your couch is sort of an object that inhales your life and breathes it back at you for months.

Which is also why spraying the air does very little, you’re perfuming air that’s about to get replaced by more air coming off the sofa.

Here’s What to Do:

• Get low and press your face right into the cushions, then the arm, then the back
• Do the same with your curtains, especially any that hang near the kitchen
• Check anything that ever got put away even slightly damp

Best move: Do your fabric check on a hot afternoon. Warm damp fabric gives off more, so August tells you the worst case.

 

5Open Every Closed Door First

 Smells build up wherever the air isn’t moving.

So that’s the closet, the spare room nobody uses, the bathroom with the door shut all day, under the sink, and the laundry cupboard if you have one.

Those are the spots where a smell gets concentrated enough that you might actually catch it, even with your worn-out nose. Your hallway is going to tell you nothing. The closet might tell you everything.

And you’re mostly looking for damp, because nearly everything that goes wrong smell-wise in a home starts with something staying wet longer than it should have.

Here’s What to Do:

• Open every door that’s normally shut, then walk the same loop again in the same order
• Look behind things and underneath things while you’re in there, not just at eye level
• Notice any room that feels warmer or stickier than the rest of the place

Best move: Start at the far end of the place and work toward your front door, so you’re going from the stalest air to the freshest.

 

6Don’t Test First Thing in the Morning

 This one is backwards from what you’d guess….!

Morning feels like the fresh start, new day, everything quiet, coffee not made yet.

But you just spent eight hours breathing your own bedroom without a single break, and that’s the longest unbroken exposure you get all day. You are more nose blind at 7am than at any other point.

Same reason the smell of your own bedroom is the one you’ll basically never catch.

You could always just do your walkthrough after you’ve been out for a few hours instead. Coming home from work, back from the shops, whatever it is.

Here’s What to Do:

• Test after you’ve been out of the house for at least two or three hours
• Coming back from somewhere cold or windy works even better since your nose clears out on the way
• Never test right after cooking or showering

Best move: Make the grocery run your test. You’re gone about an hour and you’re carrying things, so you’ll walk in without overthinking it.

7Learn What “Just Open a Window” Does

People say air it out like it’s one single thing, and there are actual numbers on this.

The measure is air changes per hour, so how many times all the air in a room gets swapped for outside air. The EPA and ASHRAE put the floor at 0.35 air changes per hour, and no less than 15 cubic feet a minute per person.

California’s Air Resources Board says it plainer. Around half an air change an hour handles the normal moisture and odors in a house with nothing big going on, and you want closer to three if you’ve just cooked fish.

Half an hour with one window cracked is nowhere near three air changes. You need two openings on different walls so the air actually moves through, and ideally a fan sitting in one of them pointing out.

Here’s What to Do:

• Open two windows on opposite sides of the place rather than one
• Put a fan in one of them facing outward so it pulls air through instead of stirring it
• Give it a solid twenty minutes, five won’t do much

Best move: Set it up right before you leave for errands, then the place resets itself while you’re gone.

8Notice What the Weather Is Doing

This one is strange, and I think about it more often than I probably should.

Fang and colleagues published a study in Indoor Air where they moved the temperature and humidity around on people and measured how the same air got rated each time. The smell’s strength didn’t really shift at all.

But people found the air a lot less acceptable as it got warmer and more humid.

Same smell, worse experience.

Which means your house can be exactly as smelly in February as it is in August and land completely differently on a guest. Warm sticky air just feels closer to everybody.

So if you’re testing, the honest version is the hot day one, that’s what your summer visitors are getting.

Here’s What to Do:

• Do at least one walkthrough on a warm, humid day with the windows shut
• If you’ve got a dehumidifier, notice how the place reads before and after you run it
• Try not to judge the whole place by how it smelled back in winter

Best move: Run the AC or a dehumidifier before people come over in summer. You’re not removing the smell, you’re making the same air sit better.

Side Note: If the whole place could use a refresh and not just a diagnosis, then these 12 cleaning hacks that leave a home smelling amazing are the next step.

 

9Know What an Air Purifier Can’t Do

This one saves money so I want to say it plainly.

Most air purifiers are built to catch particles. Dust, dander, pollen, all that kind of thing, and they’re really good at it.

But the California Air Resources Board is clear that the common ones won’t remove odors or gases or VOCs. For that you need a genuine amount of charcoal or some other sorbent material in the filter, and a lot of the popular ones have a thin token carbon layer that’s mostly decoration.

So if you bought a purifier and the place still smells the same, your purifier isn’t broken, it was never the tool for that job.

Here’s What to Do:

• Look at what’s in the filter and check for a real amount of activated carbon, not a sheet
• If odor is your actual problem, put the money into ventilation and washing fabric instead
• Keep the purifier going for dust and allergies where it earns its keep

Best move: Run it in the room you actually sit in with the door shut, rather than parking it in the hallway.

 

10Assume the Bad Stuff Went First

This is the mean part, and I’m sorry about it.

A study in Building and Environment this year compared how people adapted to a nice smell (lemon) against an unpleasant one (acetic acid, so basically vinegar). The unpleasant one faded faster, and people bounced back from it quicker once they left too.

So the order in which your nose stops noticing things isn’t random. The stuff you most want to know about is the stuff you lost first.

BUT it’s not fully settled, to be fair… A 2017 paper in Scientific Reports found the opposite pattern, though the authors pointed out that none of their smells were properly foul. 

So this means that whatever you can still smell in your house probably isn’t the problem.

Here’s What to Do:

• Trust a guest’s answer over your own nose even when you disagree with it
• Go and check the boring possibilities first, so the drains and the bins before anything else
• Don’t rule something out just because you personally can’t smell it

Best move: Write down the five likeliest sources in your place and check them on a schedule. Your nose won’t tell you when one of them turns.

Side Note: if the whole place needs the cozy treatment and not just a diagnosis, then here are 12 brilliant ways to make your home warm and cozy.

 

11Fix One Thing at a Time

Whether this feels slow is kind of up to you, but it matters more than it sounds.

Because adaptation is specific to one smell, if you deep clean the carpet and wash the curtains and empty out the fridge and buy a diffuser all in one Saturday, and the place smells better after… you’ve learned nothing.

You don’t know which one did it. And you don’t know which one is coming back in three weeks.

You could always just do one, wait a few days, get somebody to give you a read on it. Then the next one.

It takes longer, and it’s how you end up actually knowing your own house.

Here’s What to Do:

• Pick the single likeliest source and deal with only that
• Wait three or four days before you change anything else
• Keep a note on your phone of what you did and what changed after

Best move: Do the free ones first, so washing fabric and getting some air through the place. Those solve it more often than people expect them to.

 

12Write It Down in the First Thirty Seconds

 This one is fun, and it takes no effort at all.

Whatever window you get is short, because habituation starts working on you immediately. So the sentence you could say about your house at second five is gone by second sixty.

So to help you with this, do what I do in my own home. I keep a note on my phone for it. Just a couple of words, like “warm,” or “dusty, or musty”.

It looks a bit silly written down. But three of those entries in a row tell you far more than one dramatic entry does.

Here’s What to Do:

• Open your notes app before you unlock the front door
• Four or five words maximum, no full sentences, just whatever hit you
• Do it a handful of times over a month, then read them all together

Best move: Write it standing in the doorway before you step in properly. You’ll be adapted by the time your shoes are off.

Side Note: Once you know what you’re dealing with, this 15-minute reset routine keeps it from creeping back on you.

 

 Good to Know 

More on What’s Going On With Your Nose

Because there is so much to this conversation, here are a few good-to-know things you should brush up on to be fully ready to tackle any smell in your home!!

 

Nose Blindness vs. Actually Losing Your Sense of Smell

These are two different things and it’s worth knowing which one you’ve got.

Nose blindness is specific and it reverses. One smell, in one place, and it comes back once you’ve been away from it for long enough.

Real smell loss is across the board. Coffee, soap, cut grass, your own dinner cooking. And it doesn’t return by itself.

It’s not rare either. Smell and taste disorders affect about 20% of adults, and about 10% of people over 65 have some degree of them.

One bad week means nothing whatsoever. But if food has tasted flat for months and you can’t pick up strong things you used to pick up easily, that’s a conversation with a doctor rather than a cleaning problem.

 

Why Your Candle Seems to Quit After 20 Minutes

It didn’t quit. You did.

Same mechanism from up top, just applied to something you were enjoying. Your receptors settle down, your brain files it as background, and twenty minutes in you’re sitting next to a lit candle you can’t detect at all while anybody walking in gets hit with it in the doorway.

That’s how a lot of us end up completely over-scenting a place by accident. You keep adding because you can’t smell what’s already there.

Rotating is the fix rather than adding. Use different scents in different rooms, and switch what you’re burning every few weeks so nothing gets the chance to turn into wallpaper.

 

The Rooms That Are Usually the Problem

If I had to rank them by how often they turn out to be the source, it goes roughly wherever the laundry sits, then the bin area in the kitchen, then the bathroom, then the bedroom.

The thread running through all of those is water. Damp fabric, damp air, and things that stay wet in between uses. The washing machine door left shut, or a bath mat that never quite dries all the way.

Living rooms almost never start it. They just collect it, because that’s where all your fabric is sitting.

 

What’s Yours and What Came With the Apartment

Renting adds a whole extra complication, which is that some of what you’re smelling was never yours to begin with.

Old carpet, whatever is living in the walls, the previous tenant’s decade in there, and the building’s shared ventilation carrying somebody else’s dinner up to you. None of that is your fault and some of it you can’t fix at all.

The test is whether the smell is stronger in your things or in the fixed parts of the place. Press your face into your blanket, then into the carpet you inherited.

If the carpet wins, that’s either a landlord conversation or a rug you buy to go over the top of it.

 

How Long It Takes to Get Your Nose Back

Recovery isn’t one clean switch, it happens smell by smell.

So you might get your house back while your candle is still completely invisible to you, and that’s normal, they’re separate adaptations running on separate timelines.

The long-exposure research found sensitivity still sitting low two weeks out for most people, which is much slower than anyone expected. Short exposures bounce back in minutes.

Practically, your nose is most useful in the first minute after a real break, and it’s downhill from there.

 

 FAQs 

FAQs About Not Being Able to Smell Your Own House 🤍

---

What Is It Called When You Can’t Smell Your Own House?

While “nose blindness” is a term coined by marketers, scientists have also broken this process down into two distinct processes. Scientists say the first occurs on the inside of your nose with an adaptation to the odor receptors, while the second occurs in your brain, where the decision is made whether or not to continue mentioning the odor to you. Since both occur simultaneously, this process accounts for how quickly complete (total) desensitization can happen.

Does Nose Blindness Go Away?

Nose blindness does go away, but it’s a longer and more confusing process than you might like. It also brings your house smell back to you one scent at a time instead of bringing everything back to you all at once. So your candle will still be in hiding for another week or two.

What Is a Home Remedy for Not Being Able to Smell?

Smell training, and it costs nothing. Thomas Hummel’s protocol has you sniff four scents (usually rose, lemon, clove, and eucalyptus) for about 20 seconds each, twice a day, for around 12 weeks. His 2009 study found trained patients improved on the Sniffin’ Sticks test while the untrained group stayed flat. It won’t help with nose blindness though, that needs distance rather than practice.

What Is the Healthiest Way to Scent Your Home?

Ventilate first and scent second. Adding fragrance to stale air mostly just gives you scented stale air, and plenty of plug-ins put more VOCs into a room that already wasn’t clearing properly. Open two windows, run a fan, wash the fabric, and then add something you love. My 8 natural ways to make a home smell amazing go in that order on purpose.

What Is the Old Lady’s Smell Called?

It’s 2-nonenal, and it’s a real compound. Shiseido researchers led by Shinichiro Haze published it in the Journal of Investigative Dermatology in 2001 after testing shirts worn by people aged 26 to 75, and they found one compound that only turned up in people over 40.

It isn’t everybody, though… a few subjects in their 60s and 70s produced so little the machine could barely find it.

 

 The Takeaway 

Stop Asking Your Own Nose and Go Ask a Friend

You will never have an opportunity to enter your house and smell it like your friend smelled it; the opportunity doesn’t exist for you.

However, you do not need that. To get what you want out of life, you just need three nights away from your home, one honest person in your life who is willing to help you see yourself (and not be influenced by how others think), and a reminder on your cell phone.

The figure that I keep coming back to is that when your sense of smell returned to normal, it was still possible to measure the dip (i.e., the odor) up until two weeks later. Your nose is not a reliable witness to your home’s odors and smells.

And once you know what you’re working with, here are apartment ideas for small spaces that’ll help you plan around the parts you can’t change.
