How to Create a Fragrance-Free, Low-Chemical Home: A Practical Guide for Chemical Sensitivity

If perfume, laundry products or a freshly cleaned room leave you with headaches, breathing trouble or brain fog, your home is the one place you can control most. This guide walks through making it fragrance-free and lower in chemicals, room by room, starting with what mainstream sources support and then what functional and environmental-medicine practitioners add. For background on the condition itself, see our multiple chemical sensitivity guide.

This is general information, not a diagnosis or a treatment plan. Symptoms like these can have other causes, such as asthma, allergies or a mast cell disorder, so it’s worth working with a licensed clinician to check ^[6].

Why start with fragrance

In the 2016 national survey, people with MCS most often named these triggers: fragranced consumer products in general (73.1%), air fresheners and deodorizers (67.6%), being in a room recently cleaned with scented products (67.6%), being near someone wearing a fragranced product (65.5%) and scented laundry products coming from a dryer vent (57.9%) ^[2]. The survey relied on self-report, so it shows what people experience rather than what causes it.

Fragrance is also hard to spot on labels. Under FDA rules, fragrance ingredients in cosmetics can be listed simply as “Fragrance,” because fragrance formulas are complex mixtures that are often trade secrets ^[3]. Many scented products used around the home, such as laundry detergents, fabric softeners, dryer sheets and room fresheners, aren’t regulated as cosmetics at all ^[3].

Step 1: Remove sources

The EPA says source control is usually the most effective approach, and often more cost-efficient than increasing ventilation ^[1]. Household products such as air fresheners, cleansers and disinfectants, aerosol sprays, paints and solvents, moth repellents, hobby supplies and dry-cleaned clothing can all release volatile organic compounds (VOCs), both while you use them and, to some degree, while they’re stored ^[7]. Studies have found several organic pollutants average 2 to 5 times higher indoors than outdoors ^[7].

• Start with the strongest scents: air fresheners, plug-ins, scented candles and scented laundry products.
• Move storage out of living space. The EPA advises against storing opened containers of unused paints and similar materials indoors and suggests buying limited quantities ^[7]. In one of the house-call case studies described below, a detached storage shed greatly reduced VOC levels in the home ^[8].
• Swap one product at a time so you can notice what changes.

Evidence: public health guidance on indoor air, not trials in MCS.

Step 2: Choose fragrance-free, low-VOC products

“Fragrance-free” versus “unscented.” These terms aren’t interchangeable. The FDA notes that some “unscented” products may contain fragrance ingredients, because a manufacturer may add just enough to mask the smell of other ingredients ^[3]. Check the ingredient list for “fragrance” or “flavor,” and be cautious with products scented with essential oils, which have no regulatory definition ^[3].

Look for third-party labels. The EPA’s Safer Choice program has a separate label that indicates a product is fragrance-free ^[9].

Cleaning and laundry. ISEAI, a society of environmental-health clinicians, suggests fragrance-free cleaning and low-VOC products as budget-friendly steps ^[10]. Simple cleaning with fewer products also means fewer sources.

Personal care. Shampoo, lotion, deodorant and hair products are worn all day and travel with you. Swapping these, and asking people you live with to do the same, can matter as much as cleaning products.

Evidence: labeling facts from the FDA and EPA; product swaps haven’t been tested in trials for MCS.

Step 3: Ventilate

The EPA lists opening windows and doors when the weather permits, running window or attic fans, and using bathroom and kitchen fans that exhaust outdoors as ways to bring in outdoor air ^[1]. When you use products that release VOCs, increase ventilation and follow label directions: if a label says to use a product in a well-ventilated area, the EPA suggests going outdoors or using an exhaust fan ^[7]. If outdoor air is smoky or polluted, the EPA advises thinking carefully before relying on ventilation ^[1].

Our clean indoor air guide covers ventilation and humidity in more detail.

Evidence: public health guidance.

Step 4: Filter the air, and avoid ozone

Air cleaners can help but don’t replace source control, and the EPA notes most aren’t designed to remove gases such as VOCs ^[4]. If you’re considering one, look for a device designed for gases as well as particles, and check that it doesn’t produce ozone.

Some devices sold as air cleaners deliberately make ozone. The EPA says ozone can damage the lungs and that, at concentrations within public health standards, ozone is “generally ineffective in controlling indoor air pollution” ^[5].

Evidence: public health guidance.

A room-by-room checklist

• Bedroom: you spend hours here, so it’s a good first room. Remove candles and air fresheners; in one house-call case study, candles had been kept in the bedrooms and living room ^[8].
• Laundry: switch to fragrance-free detergent and skip dryer sheets and scented fabric softener ^{[3, 2]}.
• Kitchen and bathroom: use exhaust fans that vent outdoors ^[1] and fragrance-free cleaners ^[10].
• Garage, closets and storage: move paints, solvents, fuels and moth repellents out of the living space where you can ^[7].
• New furniture, flooring and renovations: building materials and furnishings release VOCs ^[7]. Ventilate well, and if possible be away during painting or remodeling.

Our MCS guide also covers workplace accommodations and planning for medical visits.

The functional and environmental-medicine view

Functional, integrative and environmental-medicine practitioners often put the home at the center of care for chemical sensitivity. These are their models and approaches, described in their terms. Mainstream bodies such as ACOEM say evidence does not exist to define MCS as a distinct disease ^[6], so read each one as a hypothesis, and talk with a licensed clinician before trying any of them.

• Loss of tolerance (“TILT”). Dr. Claudia Miller proposes that an initial exposure causes susceptible people to lose tolerance, after which tiny amounts of everyday chemicals trigger symptoms; she calls it a “yet-to-be-proven” theory ^[11]. In this model, lowering everyday exposure is the foundation. Evidence: a theory.
• Environmental house calls. Miller’s research group visited the homes of people with chemical intolerance, measured indoor VOCs, and made a personal action plan, such as switching to unscented cleaning, laundry and personal care products and isolating VOC sources. In three case studies, symptom improvement went along with lower indoor VOCs, most notably fragrances, and one home saw a 76% drop in total VOCs ^[8]. Evidence: three case studies by the program’s developers, without a comparison group.
• Total exposure “load.” ISEAI groups chemical sensitivity with mold illness and MCAS as “environmentally acquired illness” and says exposures “may be cumulative” ^[12]. Practitioners who share this view often tackle mold, water damage and chemicals together; see our mold toxicity guide. Evidence: a professional society’s position based on clinical experience.
• “Detox” approaches. ISEAI says treatment often involves reducing exposure and what it calls “detoxification” ^[12]. The AAAAI describes sweating and oral minerals and oils as an undocumented form of “detoxification” ^[13], and the NIH’s complementary-health center says studies of “detox” programs are few and of low quality ^[14]. Evidence: no controlled trials in MCS found.
• Calming a sensitized nervous system. Dr. Neil Nathan writes that he first recommended limbic retraining mainly for patients with MCS ^[15]. One small trial of a similar program in fibromyalgia and chronic fatigue reported improvements, but fewer than half of participants finished it ^[16]. Evidence: clinical observation and one small trial in related conditions; we found no controlled trials in MCS.

A caution about going too far. The AAAAI cautions that some avoidance programs become extreme, and that there is evidence such programs may make patients worse ^[13]. Many people find it helps to aim for a home that feels manageable, not perfect, and to keep work, relationships and activities in view.

What’s known and what’s debated

Generally accepted: fragranced and VOC-releasing products are common indoors, and removing sources is the most effective way to improve indoor air ^{[1, 7]}. Many people report symptoms from these exposures ^[2].

Debated: what causes MCS. A systematic review of 37 challenge studies found people with MCS reacted mainly when they could tell active exposures from sham ones, which suggests expectations may play a role ^[17]; Miller’s group proposes a biological explanation instead ^[11]. Either way, symptoms are real, and reducing exposure is a reasonable, low-risk step.

Questions to ask your doctor

• Could asthma, allergies or another condition explain my reactions?
• Which changes at home are most worth trying first for me?
• How can I make changes without letting avoidance take over my life?
• Would a referral to an allergist, occupational medicine doctor or counselor help?

The bottom line

Start with the sources you can remove, especially fragrance, then ventilate and filter, and go one change at a time. A licensed clinician can help rule out other causes and fit these steps to you. For more, see our multiple chemical sensitivity guide and clean indoor air guide.
