Your home should be the one place you control the air. Then a neighbor runs the dryer, the building plugs an air freshener into the hallway, or the cleaners mop the stairs with something piney. This page covers what’s known, how to talk to neighbors, and what you can ask a landlord for.

You’re not imagining the dryer vent
Scented laundry products put fragrance chemicals into outdoor air: in two homes, limonene (a citrus scent chemical) came out of the dryer vent only when fragranced detergent or dryer sheets were used (up to 14.7 ug/m3), not in the no-product runs. Moderate evidence. Steinemann 2013
Among people with symptoms, 56% named other people's perfume, 32% air fresheners and 28% other people's freshly washed (fabric-softened) clothes as triggers. Moderate evidence. Elberling 2005
Among people who get migraines, 40.8% (US) and 29.1% (Australia) report health problems from the scent of laundry products coming from a dryer vent, with asthma attacks the most frequently reported effect in this group. Moderate evidence. Goodman, Nematollahi & Steinemann 2020/2021
One limit: those measurements were taken at the vent itself. Nobody has yet measured what the people next door actually breathe. More in our article on what comes out of your dryer vent.
Switching detergent made a big difference
In a small study, switching cut the scent chemical at the vent and in the laundry room. Switching from a fragranced to a fragrance-free laundry detergent cut the fragrance chemical D-limonene coming out of the dryer vent by up to 99.7% (mean 79.1%) within one month, in real households, with no extra cost or apparent inconvenience. Moderate evidence. Goodman 2019 Switching to fragrance-free laundry detergent also reduced D-limonene in the laundry room's own indoor air, not just at the dryer vent, by up to 72.7% (mean 45.8%) within one month. Moderate evidence. Goodman 2019
So there’s a concrete, cheap thing to ask for: fragrance-free detergent and no scented dryer sheets. The study didn’t measure health effects or what neighbors breathe, but it’s the obvious first step.
Talking to a neighbor
Assume they’ve never thought about where their dryer air goes. Keep it friendly and specific.
- Pick a calm moment, not the minute the dryer starts.
- Say what happens to you, not what they’re doing wrong.
- Make one small, concrete ask, and make it easy to say yes.
Hi, I'm [name] from [unit/next door]. This is a bit awkward, but I get [headaches / trouble breathing] from scented laundry products, and when your dryer runs the vent air comes [into my window / onto my patio]. Would you be open to trying a fragrance-free detergent and skipping dryer sheets? I'm happy to buy the first bottle. Thanks for hearing me out.
If they say no, you haven’t lost anything. If you want a record, follow up with a short, friendly note, and see below for what a landlord can do.
What to ask a landlord or building for
The shared parts of a building are the landlord’s call, and that is where a request has the most weight. California’s public health department recommends the same basics for workplaces. The California Department of Public Health recommends enforced fragrance-free workplace policies, no air fresheners or fragranced cleaners, and better ventilation instead of odor masking. Moderate evidence. Weinberg 2017
- No air fresheners, plug-ins or scent diffusers in hallways, elevators, lobbies and the laundry room.
- Fragrance-free products for cleaning shared areas, and a heads-up before carpet shampooing, painting or pest treatment.
- Fragrance-free cleaning when your unit is turned over before you move in.
- A different unit, laundry schedule or vent position if the problem is one specific source.
Air fresheners are worth the fight. About 1 in 5 US adults (20.4%) reported health problems from air fresheners, and 23.6% from being near someone wearing a fragranced product. Moderate evidence. Steinemann 2016
From the HUD and Justice Department joint statement (2004), general guidance
- Under the Fair Housing Act, a “reasonable accommodation” is “a change, exception, or adjustment to a rule, policy, practice, or service that may be necessary for a person with a disability to have an equal opportunity to use and enjoy a dwelling, including public and common use spaces.” [HUD & DOJ]
- Explain what you’re asking for and, if it isn’t obvious, how it relates to your disability. Putting it in writing “will help prevent misunderstandings regarding what is being requested, or whether the request was made.” [HUD & DOJ]
- “A provider has an obligation to provide prompt responses to reasonable accommodation requests.” [HUD & DOJ]

Inside your own four walls
Start with what you can change today. EPA's own first advice on indoor VOCs is to identify and remove the source, ventilate when products are used, and buy only what you will use soon, because even closed containers leak. Moderate evidence. US EPA 2026
