Non-Toxic Nursery Checklist

Newborns spend up to 17 hours a day in the nursery. The decisions made about materials, finishes, and air quality before a baby arrives have a direct and lasting effect on the indoor environment they develop in.

The nursery is a system. Treating it as a collection of individual products is where most parents go wrong.

Each piece of new furniture off-gasses VOCs. Add fresh paint, new synthetic fabrics, and a small enclosed room — the combined effect is higher than any single product label suggests. This checklist addresses the room as a whole. The picks are what we'd put in our own nurseries.

Before the checklist

The nursery as a system, not a collection of products

Each piece of new furniture off-gasses VOCs during its first weeks in use. A freshly painted room adds to that load. New synthetic fabrics and rugs contribute their own chemical signatures. In isolation, any single item may fall within acceptable limits. In a small enclosed room, the combined effect can be meaningfully higher.

The most effective approach is not to spend more on individual products but to think about the room as a system. VOC off-gassing is highest in the first 72 hours after installation. Assembling nursery furniture at least two weeks before the due date — with windows open — reduces the chemical load in the room by the time it is actually occupied. This single step costs nothing.

Highest-impact free action

Assemble all nursery furniture at least two weeks before the baby's arrival. Run ventilation (open windows or an air purifier) continuously during that period. This reduces VOC concentration more effectively than upgrading individual products.

Part 1 of 3 — Furniture materials and finishes

Furniture materials and finishes

All large furniture items (crib, dresser, wardrobe) are GREENGUARD Gold certified
GREENGUARD Gold tests for 10,000+ chemicals under enclosed-space conditions. It is the most meaningful certification for furniture chemical safety in a nursery context. UL GREENGUARD database
Any composite wood components meet CARB Phase 2 for formaldehyde emissions
MDF, particleboard, and plywood are common in flat-pack nursery furniture. CARB Phase 2 sets the most stringent US formaldehyde limits for these materials. CARB composite wood programme
Paint on all surfaces is water-based, low-VOC, and cured before the baby arrives
VOC emissions from paint peak immediately after application and decline over time. Paint the nursery at least 2 weeks before the baby arrives and ventilate continuously. Confirm the paint's VOC content with the manufacturer — 'low-VOC' has no single regulatory definition.
Flooring is hardwood, tile, or low-VOC sealed — not new synthetic carpet
New synthetic carpet and vinyl flooring are significant sources of VOC emissions and can also harbour allergens. If carpet is already in place and in good condition, it is safer than installing new synthetic carpet before the baby arrives.
No furniture is placed directly below hanging items that could fall
Shelving, wall art, and mounted storage above the crib or changing area create fall risks. Confirm all wall-mounted items are properly anchored to studs, not just drywall anchors.
Part 2 of 3 — Air quality and ventilation

Air quality and ventilation

An air purifier with a HEPA filter is running in the nursery
A HEPA filter removes particles down to 0.3 microns — covering dust, pollen, pet dander, and some mould spores. Run the purifier continuously during the furniture assembly period and after the baby arrives.
The air purifier also includes an activated carbon filter
A HEPA filter captures particles but does not absorb gases or VOCs. An activated carbon stage addresses the gas-phase chemical emissions from new furniture and paint.
Nursery temperature is maintained between 68–72°F (20–22°C)
The AAP recommends keeping the infant sleep environment at a comfortable room temperature — approximately 68–72°F. Overheating is a recognised risk factor in sleep safety.
No candles, air fresheners, or strong cleaning products used in the nursery
Candles and synthetic air fresheners introduce VOCs and particulates into the air. Use fragrance-free cleaning products in the nursery. If disinfecting is needed, choose products that are fully dry and ventilated before the baby is in the room.
Nursery is ventilated daily — at least one window opened for 15+ minutes
Mechanical air purifiers supplement but do not replace fresh air exchange. Daily ventilation is the most effective way to reduce accumulated indoor air pollutants.
Part 3 of 3 — Fabrics and bedding

Fabrics and bedding

Crib sheets are GOTS certified organic cotton or OEKO-TEX Standard 100 certified
GOTS certification covers the entire production chain from raw fibre to finished fabric. OEKO-TEX Standard 100 tests the finished fabric for harmful substances. Either is an acceptable standard for infant bedding. GOTS certificate search
No bumpers, pillows, or loose bedding in the crib
The AAP is explicit: the sleep surface should contain only the mattress and a fitted sheet. All other items — including breathable bumpers — increase sleep risk and should not be in the crib.
Any rugs are low-pile and free of synthetic backing
High-pile rugs and rugs with rubber or synthetic backing can off-gas VOCs and harbour allergens. Low-pile natural fibre rugs (wool, cotton, jute) with no synthetic backing are the lower-risk choice.
Curtains or blinds do not have cords that reach below 1.5m from the floor
Blind cords are a strangulation risk for children. The CPSC recommends cordless window coverings in any room where children are present. CPSC window covering safety
All soft furnishings have been washed before use
New fabrics can contain finishing chemicals, dyes, and manufacturing residues. Wash all crib sheets, blankets, and fabric items before they come into contact with the baby — in fragrance-free, dye-free detergent.

Our picks for a cleaner nursery

Premium
Medify MA-25 Air Purifier
Best for: H13 HEPA filtration with activated carbon for nursery VOC and particle removal
H13 True HEPA filtration captures 99.97% of particles down to 0.1 microns. Activated carbon stage addresses gas-phase VOCs from new furniture and paint. Covers up to 500 sq ft. Quiet operation suitable for nursery use. CARB certified.
Trade-off: Covers more area than most nurseries require — the additional coverage is not a disadvantage but does add cost.

Mid-range
Naturepedic Organic Crib Sheet Set
Best for: GOTS certified organic cotton crib sheets
GOTS certified organic cotton — certification verified via GOTS public certificate search. No dyes or finishing chemicals that require disclosure. Machine washable. Fitted sheet design confirmed compatible with standard crib mattress dimensions.
Trade-off: Organic cotton at a higher price point than conventional alternatives. The cost difference is the certification premium — justified for families prioritising verified material safety.

Budget
Levtex Baby OEKO-TEX Crib Sheet
Best for: OEKO-TEX Standard 100 certified fabric at accessible price
OEKO-TEX Standard 100 certified. Tested for harmful substances at every production stage. Machine washable. Standard crib dimensions. Available in multiple colourways without additional chemical treatments.
