A certified vinyl or laminate floor, installed well, adds very little to the air in your home. Three things decide it: the seal on the box, how the floor goes down, and whether moisture can get under it.
Luxury vinyl plank and tile raise two questions. How much does the floor give off while it's new, and which plasticizer keeps it flexible? A FloorScore or GREENGUARD Gold seal answers the first. On rigid-core vinyl, the ASSURE Certified seal answers the second.
Laminate raises one main question: formaldehyde from the resin that holds its fiberboard core together. Federal law caps it, and every laminate sold in the US must carry a TSCA Title VI label.
Whichever you choose, the installation and the first two weeks matter as much as the plank. A click-together floor needs no glue, and fresh air in a cool, dry house clears what a new floor releases.
Each part of a vinyl or laminate job has one thing to check.
| What you're buying | The air question | What to look for |
|---|---|---|
| Luxury vinyl plank or tile | VOCs while it's new | FloorScore or GREENGUARD Gold |
| Rigid-core vinyl (SPC or WPC) | VOCs, plus ortho-phthalates | ASSURE Certified seal |
| Laminate | Formaldehyde from the core | TSCA Title VI label (required) |
| Glue for a glue-down floor | Solvents while it cures | Its own FloorScore or GREENGUARD seal |
| A separate pad | What the foam gives off | Its own low-emission certificate |
| The old floor coming out | Asbestos in older vinyl and glue | Test it or cover it; never sand it |
Which is better for indoor air quality, vinyl or laminate?
Vinyl and laminate are even on air quality when both carry an emission seal, so let the room decide. Where water is likely, choose waterproof vinyl. A floor that stays damp underneath can grow mold, and mold is an air problem.
That puts luxury vinyl in basements, bathrooms, laundry rooms and the back entry where snow melts off boots all winter. In bedrooms, living rooms and upstairs halls, either floor works, so pick the look and feel you like. The laminate we carry clicks together and floats, with no glue in the room. Some vinyl goes down with adhesive, which adds one more product to check.
For a nursery, or for anyone in the house with asthma, the seal matters more than the material: look for GREENGUARD Gold. Laminate has no vinyl in it, so the plasticizer question belongs to vinyl alone. If you're also weighing durability, looks and price, our side-by-side comparison of vinyl and laminate covers the rest.
Is luxury vinyl flooring toxic?
No, a luxury vinyl floor with an emission seal has been tested against California's health-based limits for what it releases into the air. Two things are still worth checking: how much it gives off in its first weeks, and which plasticizer made it flexible.
Luxury vinyl is made mostly of PVC, in layers. A backing and a core sit under a printed design and a clear wear layer. Plasticizers are what let vinyl bend.
VOCs and the new-floor smell
VOCs, or volatile organic compounds, are chemicals that evaporate from solid and liquid products at room temperature. Paint, cleaners, air fresheners, furniture, glue and building materials all release them. That's why many VOCs run higher indoors than outdoors, sometimes ten times higher. At high enough levels they irritate the eyes, nose and throat, and they can bring on headaches and nausea.
A new vinyl floor releases the most VOCs in its first days, and the amount falls from there. That early release is the new-floor smell, and it fades as the floor airs out.
What the Duke study found about phthalates, and what to ask for
Phthalates are plasticizers that make plastic soft and flexible, and vinyl tile flooring is among the products that can contain them. They're released slowly, settle on floors and collect in house dust. That's how young children pick them up.
A Duke University study looked at children in homes with vinyl flooring in every room. They had 15 times more of a breakdown product of one phthalate, benzyl butyl phthalate, in their urine than children in homes without vinyl. That phthalate belongs to the ortho-phthalate family.
The answer is a vinyl floor made without ortho-phthalates. On rigid-core vinyl, the ASSURE Certified seal limits them to 0.1 percent of the product, alone or combined. Glue-down and loose-lay vinyl fall outside that program, so ask for the maker's written statement that the floor has no ortho-phthalates.
An emission seal like FloorScore can't tell you this. It measures what reaches the air, and phthalates travel in dust.
Does laminate flooring give off formaldehyde?
Yes, laminate gives off a small amount of formaldehyde, as anything with a composite wood core does, and federal law caps it. Laminate is built on high-density fiberboard: wood fibers pressed together with resin. Some of those resins release formaldehyde.
Since 2019, the EPA has required every composite wood product sold in the US to be certified and labeled TSCA Title VI compliant. The rule reaches finished products made with that wood, so it covers laminate, whether the floor is made here or imported. Laminate bought before then may carry a CARB Phase 2 label instead, which is California's version of the same limit.
Look for "TSCA Title VI compliant" on the box or the paperwork. Every laminate has to carry it. A FloorScore or GREENGUARD Gold seal on top of it covers the floor's other emissions.
Formaldehyde from composite wood drops over time. Heat speeds up its release, and humidity can raise it. On a hot, sticky Michigan afternoon, indoor levels run higher than on a cool, dry day, whatever floor you have.
How to choose vinyl or laminate that meets indoor air quality guidelines
To choose vinyl or laminate that meets indoor air quality guidelines, check the room first, then the seals, then the installation. These are the checks we'd run on any floor you're considering:
- Match the floor to the room: waterproof vinyl where water is likely, either floor elsewhere.
- Find the emission seal: FloorScore at least, GREENGUARD Gold for a nursery or anyone with asthma.
- For laminate, confirm the TSCA Title VI label.
- For vinyl, confirm no ortho-phthalates: the ASSURE seal on rigid core, a written statement on other vinyl.
- Choose a click-together floating floor where the room allows. For glue-down, get an adhesive with its own seal.
- Choose a floor with the pad attached, or a separate pad with its own low-emission certificate.
- Keep anyone sensitive out while the floor goes in, then keep fresh air moving for two weeks.
What FloorScore, GREENGUARD Gold, TSCA Title VI and ASSURE mean
GREENGUARD Gold is the stricter of the two emission seals. TSCA Title VI is the legal requirement for laminate, and ASSURE is the only one of these labels that tests what rigid vinyl contains.
| Label | What it checks | Where you'll see it |
|---|---|---|
| FloorScore | Emissions against California's limits; retested yearly | Hard floors and flooring glue |
| GREENGUARD Gold | Those limits plus 360-plus chemicals and total emissions | Floors, pads, many home products |
| TSCA Title VI | Formaldehyde from a composite wood core | Required on every laminate |
| CARB Phase 2 | The same formaldehyde limit, California's label | Laminate from before 2019 |
| ASSURE Certified | Indoor air, heavy metals, ortho-phthalates, performance | Rigid-core vinyl (SPC and WPC) |
FloorScore and GREENGUARD Gold both test a floor in a sealed chamber using the same California method. That method compares what the floor releases with California's long-term health limits for each chemical it measures. GREENGUARD Gold adds limits on more than 360 chemicals and on total emissions, which makes it the seal for a nursery, a classroom or a home where someone has asthma. FloorScore requires yearly retesting and a factory audit.
A seal belongs to a specific product, not a whole brand, unless the maker certifies its entire line. You'll find it on the product page or the spec sheet, and the FloorScore program keeps a public list of certified products you can check.
How installation affects the air in your home
Installation is the part of the job no seal covers. Emissions run highest while a floor is going in, so anyone sensitive to smells or chemicals should stay out of the area until the work is done. The glue and the pad are separate products, and a seal on the plank says nothing about them.
Glue-down vinyl and adhesives
A glue-down vinyl floor adds an adhesive that releases solvents while it cures. A click-together floating floor adds none. If your room calls for glue-down, ask for an adhesive with its own FloorScore or GREENGUARD Gold seal, and plan on extra fresh air for the first few days.
Pads and underlayment
A floor with the pad attached leaves one product to check instead of two. Many of the vinyl floors we carry come that way, and so does Pergo Elements laminate. A separate foam or cork pad should carry its own low-emission certificate. Our guide to underlayment options for laminate covers the types.
Taking out an old vinyl floor
An old vinyl floor can hold asbestos in the tiles, the backing of sheet vinyl or the glue underneath, and you can't tell by looking. Sanding, scraping or chipping it releases the fibers into the air.
If the old vinyl is flat and in good shape, a new floating floor can usually go right over it. That's what the EPA recommends for asbestos flooring that needs replacing. If it has to come out, have a trained and accredited asbestos professional test it and remove it, and don't take samples yourself.
Skip liquid adhesive removers and solvents on old glue, too. They're a heavy dose of VOCs, and they can cause problems with the new floor later.
How long does new vinyl or laminate flooring smell?
A new vinyl or laminate floor gives off most of its emissions in the first days and weeks, and the smell fades steadily after that. The certification test measures a floor on day 14. A California test method treats that as a realistic time to move back in after a renovation.
Open windows while the floor goes in and for the first few days. Run the bathroom and kitchen exhaust fans longer than usual. Keep the house cool and dry, since warmth and humidity push emissions up.
In January, with the house shut tight, crack a window for short spells and let the exhaust fans do more of the work. In July, run the air conditioning or a dehumidifier rather than letting the house heat up. If a strong smell hangs on for weeks, look at what else came in with the project, such as an adhesive, a pad or a new cleaner.
Can mold grow under vinyl plank or laminate?
Yes, mold can grow under vinyl plank or laminate if water gets underneath or moisture rises through the concrete. The floor itself doesn't feed mold; trapped moisture does, so keeping water out from under it is the whole job.
Basements are where this matters most around Metro Detroit. A concrete slab can pass moisture up from the ground, so test it before any floor goes down. A floating floor over concrete belongs on a 6-mil plastic vapor barrier. That sheet won't fix a wet slab, though; the water has to be dealt with first.
For basements, bathrooms and laundry rooms, waterproof vinyl is the usual choice. With any floor, dry a leak or a big spill within 24 to 48 hours, which in most cases keeps mold from starting. Holding indoor humidity between 30 and 50 percent helps as well.
Are vinyl and laminate good for allergies and asthma?
Yes, vinyl and laminate are good choices for allergies. A smooth floor gives dust, pollen and pet dander nowhere to settle in, so a damp mop or a vacuum lifts them off. The Asthma and Allergy Foundation of America recommends solid-surface flooring for people with dust-mite allergies.
Dust mites thrive once humidity climbs past 50 percent. The same 30 to 50 percent range that holds off mold keeps them in check too. For anyone with asthma or a strong reaction to smells, choose a GREENGUARD Gold floor. COREtec, one of the brands we carry, certifies every floor in its line to GREENGUARD Gold.
Cleaning vinyl and laminate without adding VOCs
Cleaning vinyl and laminate is easy on the air if you keep it simple, since cleaners and air fresheners release VOCs of their own. Damp-mop or use a vacuum with a HEPA filter. Use a plain cleaner your floor's maker approves, and skip scented sprays. The federal Safer Choice label on a cleaner means every ingredient in it has been reviewed for safety.
Is vinyl or laminate safe for babies and toddlers?
Yes, vinyl and laminate are safe for babies when the floor is certified and you keep up a few habits. Babies live on the floor and put their hands in their mouths, so floor dust matters more for them than for anyone else in the house.
For a nursery, choose a GREENGUARD Gold floor, and with vinyl, one made without ortho-phthalates. Put it in a few weeks before the baby arrives, so the new-floor emissions have dropped by the time the room is in use. Wet-mop regularly, wipe dust with a damp cloth and wash little hands often. The same routine suits a crawling toddler and a dog who naps on the floor.
If your vinyl or laminate floor is already installed
If your vinyl or laminate is already down, start with the box or the paperwork. A TSCA Title VI or CARB Phase 2 label on laminate means it was made to the federal or California formaldehyde limit. A FloorScore or GREENGUARD seal on vinyl means it passed the California emission test. Emissions from a new floor keep falling, and fresh air, cool rooms and a dehumidifier help them fall faster.
A home test kit for formaldehyde won't settle the question. The EPA hasn't verified any of them, and even a lab test of your air can't separate the floor from furniture, cabinets or a gas stove. If someone in the house has symptoms you think could come from a new floor, see a doctor and call your local health department.

Vinyl and laminate air quality questions
Why does my flooring have a Prop 65 warning?
A Prop 65 warning means the company that made or sold the floor knows or believes it contains a chemical on California's list. California's Prop 65 office says a business can add the warning on that basis alone, without measuring how much reaches you, so the warning doesn't tell you your exposure.
You'll see it in Michigan because the law covers products sold into California, online sales included. Ask which chemical triggered it, then check the floor's seals.
Will an air purifier help with the new-floor smell?
Yes, a little, if it has a filter made for gases, but fresh air does more. Many portable air purifiers carry only a particle filter, which catches dust and pollen but not the gases a new floor releases. If you buy one for a new floor, choose a model with an activated carbon filter, and let open windows and exhaust fans do most of the work.
Is laminate made overseas safe?
Yes, imported laminate has to meet the same formaldehyde limit as laminate made here. Composite wood products must be certified and carry the TSCA Title VI label when they enter the country. The label on the box tells you more than where the floor was made.
Is SPC or WPC vinyl better for indoor air quality?
It depends on the seal: neither an SPC core nor a WPC core is cleaner for the air by itself. SPC has a stone-and-plastic core, and WPC has a core of wood pulp and plastic. The ASSURE Certified program covers both with the same requirements for indoor air, ortho-phthalates and heavy metals.
