Pros

Fabric feels thick, soft, and smooth, with strong seams and consistent quality across multiple purchases.
Blocks enough light to darken a room significantly, and helps insulate against heat and cold.
Both sides are the same fabric rather than a rubbery backing, so they look polished from either direction.
Wrinkles from packaging come out with a dryer cycle or ironing, and the curtains hang cleanly once smoothed.
Provides full privacy even in lighter colors.

Cons

Not true 100% blackout; lighter colors in particular let noticeable light through, closer to 70-80% blocking.
Colors can run darker or more muted than the listing photos suggest, especially yellows and lilacs.
Arrive with deep fold creases that take real time to iron or steam out.

Triple-weave polyester with a silver coating on the back side. The silver layer is what does the heavy lifting for light blocking and thermal insulation; the front faces the room as a smooth, solid-color fabric.
Sold in pairs across a wide range of sizes and colors, so you can match different windows in the same home without mixing brands or fabrics.
The silver-backed design helps limit heat transfer in both directions, keeping rooms cooler in summer and reducing drafts in winter. If you're shopping for non-toxic curtains for a nursery or bedroom, the thermal layer does double duty.
Densely woven enough to dampen outside noise, which matters most for street-facing windows or rooms where someone sleeps during the day.

Light Natural Linen Sheer Curtain

Pros

Fabric feels substantial and well-constructed, with stitching and finishing that hold up over multiple washes and ironings.
Filters light while still providing enough privacy for bedrooms and street-facing windows.
Wrinkles from packaging mostly fall out after hanging, so steaming or ironing isn't strictly necessary.
Available in longer lengths (up to 144 inches) that are hard to find elsewhere in natural fabric sheers.

Cons

The rod pocket opening is tight, making panels difficult to slide back and forth even on thinner rods; clip rings are a common workaround.
Color consistency can vary between panels in the same order, especially in the Natural shade, which has shown up in both taupe and beige tones.
Panel lengths within the same order can differ by 1 to 3 inches, so ordering extras and matching may be necessary.
Gray shades lean noticeably purple, which makes matching to existing gray decor tricky.

Pure linen with an open weave, so it filters and softens incoming light rather than blocking it. You still get privacy, but rooms stay bright and airy.
Sold as a single panel, not a pair. If you're covering a standard window, you'll likely need to buy two.
Linen has a naturally textured, slightly irregular look that's different from the smooth uniformity of polyester sheers. Expect visible slubs and subtle variations from panel to panel.
The fabric softens and develops more drape with each wash, so these non-toxic curtains will look and feel different after a few cycles than they do out of the box.
Handcrafted in a family-owned factory using European flax linen. The edges are double-layered at the top, bottom, and sides to prevent fraying and add weight to the hem.

Quince
See price

European flax linen front panel with a cotton lining behind it. The cotton layer adds medium opacity for light filtering and helps protect the linen from color fading over time.
Sold as a single panel, not a pair. Most windows need two, so plan to buy accordingly.
Dual top treatment lets you hang these with either a back tab or pole top, depending on the look you want. A grommet version is also available separately.
Linen will wrinkle; that's inherent to the fabric, not a defect. Dry clean only, since washing can cause shrinkage.
Quince ships factory-direct and skips the traditional retail supply chain, which is how these non-toxic curtains come in well below comparable European linen panels from brands like Pottery Barn, Crate & Barrel, and RH.
Available in 14 colors and multiple width/length combinations, including a 96" wide panel for larger windows.

ATLINIA

100% Linen Sheer Curtains

Pros

Well-stitched construction with a quality feel that multiple people describe as looking expensive.
Sheer enough to let natural light flood in while still providing meaningful privacy from the outside.
Hidden rod pocket makes mounting easy and looks clean once hung.
Filters direct sun effectively, useful for protecting furniture and rugs from afternoon light.

Cons

Sold as a single panel, but the listing language has led multiple buyers to expect a pair.
Expect noticeable shrinkage after washing: one person reported about 3 inches in width and 1 inch in length on low dry.
Wrinkles easily and won't fully smooth out even with ironing, which is inherent to the fabric but worth knowing.

Made from French flax linen, these are sheer panels that filter and soften incoming light rather than blocking it entirely. You'll still see the outdoors through them, but they diffuse brightness and add a layer of privacy.
Sold as single panels (or two-packs depending on the retailer), unlined. If you're shopping for non-toxic curtains and want a natural fiber option without synthetic linings or coatings, linen sheer is about as simple as it gets.
Linen will wrinkle, and the brand treats that as a feature rather than a flaw, noting that ironing is optional. The texture has a relaxed, slightly rumpled look that leans farmhouse or boho.
Three hanging methods built into each panel: back tab, rod pocket, and hook ring/drapery pin compatibility. That means you can switch hardware without replacing the curtains.
ATLINIA sources its flax from Normandy, France, and sells direct rather than through wholesale distributors. The brand's broader line is all linen home textiles: bedding, table linens, and bath.

Sleepout

Loop Blackout Curtains

Free From: Azo Dye Free, Formaldehyde Free, Heavy Metal Free, Low VOC, PFAS Free, Phthalate Free
Certified: GREENGUARD, OEKO-TEX Standard 100

Sleepout
See price

Sold as a set of two panels with six built-in hanging styles: backtabs, two rod pockets, loops, and compatibility with rings and track systems. They slide onto any standard curtain rod without tools or extra hardware.
Most blackout curtains leave a visible strip of light where the two panels meet in the middle. These are designed to overlap and seal that center gap, which is where a lot of light leakage actually happens.
The backing is off-white and reflects sunlight rather than absorbing it, which helps keep the room cooler. It also provides thermal insulation in winter and reduces noise.
Most blackout curtains on the market haven't been independently tested for chemical safety. Sleepout pulls random units from production and screens them through third-party labs against a long list of substances, making these an uncommon option if you're specifically shopping for non-toxic curtains.
Sleepout started when the founder, a lifelong light-sensitive sleeper, couldn't find a curtain that actually blocked all light without resorting to tin foil and improvised fabric. The company ships from Texas and focuses exclusively on blackout products.

INK+IVY

100% Cotton Single Panel Curtain

Pros

The textured pattern looks better in person than in the listing photos, and multiple people say they add a high-end, boho feel to a room.
Fabric is thick and lined, giving them a substantial weight and good drape.
Accurate sizing, and they hang well straight out of the package with minimal wrinkling.
Sunlight filters softly through the cutout pattern, which creates a cozy dappled effect for rooms where full blackout isn't needed.

Cons

Not effective as blackout curtains; light comes through the cutout design, and heat insulation is mediocre.
Sold as one panel per package, so outfitting multiple windows adds up quickly.
Fabric sheds lint and may need washing before hanging.
The ivory color's pattern is bolder than the main listing photo suggests; check the secondary images for a more accurate read.

Sold as a single panel, so you'll need to buy two for standard window coverage. Each panel has both a rod pocket and back tabs, giving you two hanging options: a gathered look or a cleaner, tailored drape.
The face is 100% cotton with a geometric print and tufted chenille stripes that add real dimensional texture, not just a flat pattern. The lining on the back is also cotton.
That cotton lining serves two purposes: it softly filters light (not full blackout) for some privacy, and it gives the panel enough weight to hang and drape well.
If you're looking for non-toxic curtains in a mid-century modern style, the Imani line also has coordinating bedding and shower curtains in the same print, so you can match across a room.
Machine washable, though the fabric may need steaming or pressing afterward to look crisp again.

Quince

European flax linen on the front, with a separate blackout liner bonded to the back. The linen gives you the natural, textured look while the liner does the work of blocking light and reducing outside noise.
Sold as single panels, not pairs. Most windows need two, so you'll want to add two to your cart if you're covering a full window.
The dual top treatment lets you hang these with either back tabs (for a clean, pleated look) or threaded directly on a pole. No need to pick one style at purchase.
If you're shopping for non-toxic curtains for a nursery or bedroom, the blackout liner here uses an acrylic-based finish rather than the vinyl or PVC coatings common in cheaper blackout curtains.
Linen will wrinkle; that's the nature of the fabric. Quince recommends dry clean only because the linen can shrink if washed at home.
Quince sources factory-direct and publishes a full cost breakdown for each product. Their curtain materials cost about $18 per panel, with the retail price covering freight, duties, and fees on top of that.

Sleepout
See price

Made to order using a multi-layer polyester fabric with a woven, linen-look finish that has a subtle crosshatch texture. The "Lux" line is Sleepout's thicker, heavier drapery fabric compared to their Classic version.
Most blackout curtains let some light through; Sleepout's fabric is third-party tested to block 100% of light. The off-white backing also reflects sunlight, which helps keep the room cooler.
Built-in versatility for hanging: the loop design includes backtabs, two rod pockets, and compatibility with track systems and rings, so it works with whatever hardware you already have.
Available in seven custom lengths and eleven colors. Because each panel is made to order, expect a longer lead time than their ready-made curtains.
Particularly relevant as a non-toxic curtains option for nurseries and kids' rooms, since most blackout fabrics achieve their light-blocking through coatings that haven't been tested for off-gassing or chemical safety.
The fabric also provides thermal insulation and noise reduction, so it serves a dual purpose in rooms where temperature swings or outside sound are an issue.

How to Swap to Non-Toxic curtains:

Here's how to swap to non-toxic curtains:

What to know about curtains

Curtains hang in your living spaces all day, so the materials they are made of and how they are treated matters. Many conventional curtains are made from synthetic fabrics treated with wrinkle-resistant, stain-resistant, or flame-retardant finishes that can release compounds into your indoor air over time.

Curtains in bedrooms and nurseries deserve the most attention since you spend long hours sleeping near them.
Heavier drapes and blackout curtains often have more coatings and backings than simple woven panels.

Check the curtains you already have

Look at the care labels and product tags on your current curtains to understand what they are made of. Labels will usually list the fabric content and may mention finishes or treatments applied to the material.

Look for terms like "wrinkle-free," "stain-resistant," or "flame-retardant" on the label or original product listing — these indicate chemical treatments.
Start by checking curtains in the rooms where you spend the most time, especially bedrooms and children's rooms.

Reduce exposure from your current curtains

If you are not ready to replace your curtains right away, a few simple steps can help lower what they release into your air. This is especially worth doing with newer curtains that still have a strong "new fabric" smell.

Wash new curtains before hanging them — a full wash cycle can remove residual finishing chemicals from the fabric.
Open windows regularly to ventilate rooms with synthetic or treated curtains, especially in the first few weeks after purchase.

Choose cleaner replacements

When it is time for new curtains, look for simple, untreated natural fabrics. Curtains made from organic cotton, linen, or hemp without added finishes are a cleaner choice for your home.

Avoid curtains marketed as wrinkle-free, stain-resistant, or with PVC-based blackout backings — look for naturally textured fabrics instead.
