The Case for a Fragrance-Free Stay: Evidence First, Comfort Always

Open the door. The room is quiet, the linens are crisp, and the air smells like…nothing. That’s not an absence of care; it’s a design choice. At EarthOMs, especially at higher tiers, we default to a fully fragrance-free standard for housekeeping, laundry, and “room scents,” with one optional exception: a sealed, guest-use-only essential-oil mist some Hosts may offer. Below is the why, grounded in published research and policy, followed by a simple, effective, scent-free cleaning playbook. References to the mentioned studies is listed at the end.

The science, in plain language

1) Indoor air concentrates what we use

Volatile organic compounds (VOCs) from everyday products – such as cleaners, air fresheners, and laundry additives – accumulate indoors, often at higher levels than outside. That’s basic indoor air physics and a consistent finding in U.S. guidance. (1)

2) “Citrus” or “fresh linen” doesn’t stay simple

Common fragrance terpenes (like limonene) can react with small amounts of indoor ozone to create secondary pollutants – ultrafine particles and aldehydes – beyond the original scent. Controlled experiments and reviews in the indoor-chemistry literature have documented this mechanism for decades. Put simply: you spray “orange”; chemistry makes something else. (2)

3) A meaningful share of people feel unwell around fragranced products

Large population surveys report that a notable percentage of adults experience headaches, respiratory irritation, or other symptoms when exposed to fragranced products, and many prefer fragrance-free environments. This isn’t rare, and it’s not limited to people with diagnosed conditions. (3)

4) Ingredients and co-ingredients matter

Fragrance mixtures are complex. Some specific fragrance substances have triggered restrictions abroad. Most notably among these being Butylphenyl Methylpropional (Lilial), prohibited in EU cosmetics since March 2022 due to reproductive-toxicity classification. This doesn’t mean “all fragrance is dangerous,” but it shows why blanket “smells good = good” is too simple for modern hospitality. (4)

5) Ongoing debate around phthalates underscores a precautionary approach

Phthalates have historically been used in fragrances (e.g., DEP as a fixative). The FDA’s current position is that phthalates “as used in cosmetics” don’t present a demonstrated safety risk; simultaneously, global reviews on endocrine-disrupting chemicals continue to raise concern about certain phthalates and exposure pathways. For a premium stay serving diverse guests, including those who are pregnant or fragrance-sensitive, the sensible choice is to eliminate added fragrance rather than litigate ingredient-by-ingredient. (5)

Bottom line: Scented products add VOCs to indoor air; those chemicals can transform into other compounds; and a substantial slice of the public reports symptoms around fragranced products. Removing added fragrance reduces avoidable uncertainty while improving clarity for guests.

What we enforce at higher tiers (and why)

  • No added fragrance in housekeeping or laundry. That includes detergents, softeners/dryer sheets, “fresheners,” plug-ins, and perfumed cleaning concentrates. It’s simpler to manage across staff and turnovers, and it respects guests who prefer neutral air.
  • Optional, sealed, guest-use-only room mist. If present, it’s clearly labeled, not pre-sprayed, and never used by staff between stays.
  • Clear, verifiable listing notes. Hosts disclose the unscented products in use (brand/type), and we display “verified on 2025” so guests know the information is current.

This is not a moral stance; it’s a quality and risk-reduction stance consistent with the research above. 

A fragrance-free cleaning playbook that still reads “luxury”

You don’t need perfume to communicate clean – you need process. Here’s the short list we recommend because it works, travels well across teams, and keeps indoor chemistry boring (that’s a compliment).

Core products (unscented)

  • Neutral pH soap for general surfaces; unscented dish and hand soaps at sinks.
  • Diluted white vinegar for mineral scale, glass, and select degreasing tasks where appropriate; baking soda as a gentle abrasive.
  • Oxygen-based whiteners (per label) for linens; unscented laundry detergent with measured dosing.
  • Microfiber cloths and mop heads laundered fragrance-free.

Core practices

  • Air exchange during turnover (windows/HVAC) and a properly rated, regularly changed HVAC filter.
  • Source removal > masking. Moisture control, drain maintenance, fabric refresh cycles.
  • Label everything. A one-page dilution/usage sheet and a photo inventory of approved unscented products keep teams aligned.

The “quiet luxury” finish

Let the room’s materials, light, and temperature do the talking. When the air is neutral, guests notice the hand of the textiles and the calm of the space – not a plume of “fresh linen.”

Quick guidance by audience

For Hosts

  • List your unscented products in the amenities/details (e.g., “unscented detergent; no dryer sheets; no plug-ins”).
  • Upload label photos during verification; we’ll show “verified on 2025.”
  • If you offer a room mist, keep it sealed and optional, placed in the welcome tray, never applied by staff.

For Guests

  • Expect neutral air on arrival.
  • If you like a light scent, use the optional mist (when provided) after you settle in.
  • Sensitive travelers can filter for fragrance-free housekeeping and laundry in listing details.
