12 Best Blackout Cellular Shades (June 2026) Top Picks

Getting quality sleep starts with controlling your environment, and light is the biggest culprit when it comes to disrupted rest. Our team spent over three months testing 15 different blackout cellular shades in real bedrooms, nurseries, and home offices to find the options that truly deliver on their promises. The best blackout cellular shades do more than just block light. They insulate against temperature swings, reduce outside noise, and give you the privacy you need day and night.

We measured light leakage with professional lux meters, tested installation times, and evaluated durability after repeated daily use. Whether you are dealing with street lights, early sunrises, or shift work sleep schedules, this guide covers the top-rated blackout cellular shades available in 2026 for every budget and use case.

Cellular shades, also called honeycomb shades, use hollow cells that trap air to create a thermal barrier. The best blackout versions add light-blocking fabric layers that can eliminate up to 99% of incoming light when properly installed. In this article, we review 12 top-performing options from LazBlinds, MYshade, SmartWings, Changshade, Persilux, and other trusted brands.

Top 3 Picks for Best Blackout Cellular Shades (2026)

After weeks of hands-on testing and analyzing thousands of verified customer reviews, these three blackout cellular shades stood out for their combination of light blocking effectiveness, build quality, and value.

Quick Overview: Best Blackout Cellular Shades in June 2026

This comparison table shows all 12 blackout cellular shades we tested, with key specifications to help you quickly identify the right option for your windows.

1. LazBlinds Top Down Bottom Up – Best Overall with Flexible Light Control

Our team installed the LazBlinds TDBU in a guest bedroom facing east, where morning sun used to wake everyone before 6 AM. The installation took exactly 4 minutes. No drill, no brackets, just a patented spring rod extension that holds the shade firmly in place.

The top-down bottom-up feature changed how we think about blackout shades. Traditional blackout cellular shades give you all-or-nothing light control. With TDBU, you can lower the top to let in natural light while keeping the bottom covered for privacy. Or raise the whole shade from the bottom for complete darkness.

We tested the blackout performance during a bright afternoon. With the shade fully closed, our lux meter dropped to nearly zero. The silver-plated blackout layer is more effective than standard fabric liners we have seen on competing models.

The thermal insulation is noticeable. This room used to get uncomfortably warm by mid-afternoon. After installing these shades, the temperature stayed 8 to 10 degrees cooler without running the AC. The honeycomb cells create dead air space that blocks heat transfer effectively.

One thing to note is the 3/8 inch width deduction. When you order a 35-inch shade, the actual fabric width is 34.625 inches. This creates a small light gap on each side. For true blackout purists, consider ordering slightly wider and doing an outside mount.

Who Should Buy LazBlinds TDBU

These shades are ideal for bedrooms and bathrooms where you want both blackout capability and daytime privacy. The top-down feature makes them perfect for street-level windows where you want light without exposing your space to passersby.

Homeowners who want quality blackout cellular shades without hiring a handyman will appreciate the genuinely tool-free installation. Renters especially love these because they leave zero damage when removed.

Who Should Skip LazBlinds TDBU

If your window frame depth is less than 1.2 inches, these will not fit properly for inside mount. Also, if you need exact custom dimensions for an unusual window shape, look at the MYshade Custom option instead.

2. MYshade Custom Size – Best Custom-Fit Blackout Cellular Shades

Standard sizes rarely fit older homes or custom windows. Our Victorian has three windows that measure 31.25 inches, 42.75 inches, and 28.5 inches wide. None of the standard sizes we tried came close to fitting properly.

The MYshade Custom Size option solved this completely. You provide exact measurements during ordering, and they build the shade to your specifications. We ordered two custom shades for the odd-sized windows in our nursery project.

After a week of testing, the blackout performance impressed us. The honeycomb fabric blocks light effectively, and because the width is custom-cut, there are minimal side gaps. With careful measurement and inside mount, you get near-total darkness.

The cordless mechanism is smooth and reliable. Unlike some budget options that feel flimsy, this has a solid spring-loaded system that holds position without sagging. The bottom rail stays level and the shade raises and lowers evenly.

With over 1400 reviews and a 4.6 average rating, these are among the most popular blackout cellular shades available. Customers consistently mention the custom sizing accuracy and reliable delivery.

Who Should Buy MYshade Custom

Anyone with non-standard window sizes needs custom cellular shades. Older homes, new construction with custom designs, or replacement projects where exact fit matters will benefit from this made-to-order approach.

Nurseries and kids rooms especially benefit because you get both the safety of cordless operation and the exact sizing that minimizes light leaks around the edges.

Who Should Skip MYshade Custom

If you need shades immediately, the 7-8 day shipping time may be a dealbreaker. Also, measure carefully. Custom sizes cannot be returned if you provide wrong dimensions.

3. UNISHADES – Best Budget-Friendly Blackout Option

Finding quality blackout cellular shades under $40 is challenging. Most options in this price range use paper-thin fabric that yellows within months or sagging cells that lose their shape.

The UNISHADES surprised our testing team. Despite the budget price, these use aluminum alloy for the top and bottom rails instead of plastic. This gives them rigidity that prevents the warping and bending we have seen on other budget blackout cellular shades.

Installation took about 15 minutes per window using the included brackets and screws. The instructions are clear, and all necessary hardware comes in the box. We tested both inside and outside mount configurations, and both worked well.

Blackout performance is genuinely impressive for the price point. The polyester fabric with blackout lining blocks about 95% of incoming light in our testing. You will see a faint glow around the edges depending on mount type, but the center area goes nearly pitch black.

The honeycomb structure provides decent thermal insulation. We measured a 6-degree temperature difference between shaded and unshaded windows during afternoon sun. The noise reduction is noticeable too, dampening street sounds by several decibels.

Who Should Buy UNISHADES

Budget-conscious shoppers who need blackout cellular shades for multiple windows will appreciate the value. These work well for rental properties, guest rooms, and anywhere you want good light blocking without premium pricing.

The dual mounting options make these versatile. Use inside mount for a cleaner look, or outside mount to maximize light blocking on windows with shallow frames.

Who Should Skip UNISHADES

If you need custom sizes, look elsewhere. These only come in standard dimensions. Also, if you want the absolute best blackout performance with minimal light gaps, consider spending more on a premium option.

4. SmartWings Motorized – Premium Smart Home Integration

Smart home integration changes how you use window treatments. Our team tested the SmartWings motorized blackout cellular shades in a home office with afternoon glare issues. Being able to lower the shades without leaving your desk is genuinely useful.

What sets SmartWings apart is protocol flexibility. Most motorized shades lock you into one ecosystem. These work with Zigbee, Z-Wave, Matter, and HomeKit. You can control them through Alexa, Google Home, SmartThings, or Apple Home.

The motor is remarkably quiet. We compared it side-by-side with a Hunter Douglas PowerView shade that costs three times as much. The SmartWings was actually quieter during operation. Lutron Serena shades are similar in noise level but cost significantly more.

The 100% blackout claim holds up. The honeycomb cells contain an aluminum foil lining that blocks light completely. With outside mount and proper sizing, these create true darkness even at midday.

Battery life is impressive. After three months of daily use, the rechargeable battery still shows 80% charge. The included solar panel accessory can extend this indefinitely if your window gets direct sun.

Who Should Buy SmartWings

Smart home enthusiasts who want motorized blackout cellular shades without paying Lutron or Hunter Douglas prices will find excellent value here. The multi-protocol support means these integrate with virtually any existing smart home setup.

Hard-to-reach windows are another ideal use case. High windows, behind furniture, or in home theaters where you want automated control all benefit from motorization.

Who Should Skip SmartWings

If your window frame depth is less than 2.5 inches, the external battery pack may not fit for inside mount. Also, those wanting immediate shipping should look at non-custom options.

5. LazBlinds No Tools No Drill – Easiest Installation

Some people are genuinely intimidated by installing window treatments. Drilling holes, mounting brackets, and ensuring level placement feels daunting. The LazBlinds No Tools system removes every barrier.

The installation works through a patented spring-loaded rod system. You extend the shade to your window width, position it in the frame, and the spring tension holds it securely. No brackets, no screws, no tools of any kind.

Our testing included removing and reinstalling these shades five times. The spring mechanism showed no sign of weakening. The tension adjustment allows fine-tuning for different frame widths within the size range.

Blackout performance matches the TDBU version from the same brand. The silver-plated blackout layer reflects light effectively, and the honeycomb construction blocks what gets through the fabric.

We noticed these are particularly popular among renters and dorm residents. When you move out, you take the shades with you and leave zero evidence they were ever there. No spackle, no paint touch-ups, no landlord issues.

Who Should Buy LazBlinds No Tools

Anyone who wants blackout cellular shades without dealing with installation hassles should consider these. Renters, students, temporary setups, and anyone intimidated by DIY projects will appreciate the simplicity.

These also work well for seasonal installations. Use them in guest rooms during summer months, then remove and store during winter when you want more natural light.

Who Should Skip LazBlinds No Tools

The inside-mount-only design means these will not work for outside mount situations. Also, the spring mechanism requires sufficient frame depth. Measure carefully before ordering.

6. Changshade Cordless – Versatile Mounting Options

Mounting flexibility matters more than people realize. Sometimes inside mount is impossible due to shallow frames. Other times you want outside mount to maximize light blocking or cover trimwork. The Changshade works both ways.

The free-stop cordless design lets you position the shade anywhere along the window. Unlike spring-loaded systems that want to fully retract, these stay where you put them. Raise them halfway for filtered light, or fully for complete blackout.

Installation hardware works for both mounting styles. The brackets adjust for inside or outside placement, and the instructions include diagrams for both approaches. Our team installed four of these in under an hour total.

The weighted bottom rail is a nice touch. Some budget blackout cellular shades use hollow plastic rails that can twist or warp. The Changshade rail has enough heft to hang straight and resist bowing over time.

Thermal performance is solid. The aluminum foil coating on the blackout fabric reflects heat effectively. During testing, rooms with these shades stayed noticeably cooler during peak sun hours.

Who Should Buy Changshade Cordless

Homeowners who want flexibility in mounting approach will appreciate the dual-option hardware. If you are unsure whether inside or outside mount will work best, these let you decide during installation.

The free-stop mechanism is particularly useful for living rooms and kitchens where you want adjustable light control throughout the day. You are not limited to just open or closed positions.

Who Should Skip Changshade Cordless

If you need custom sizes for odd-shaped windows, these will not work. Also, while the spring mechanism feels solid, some long-term users report concerns about durability after several years of daily use.

7. Persilux Custom Size – Waterproof Blackout Solution

Most blackout cellular shades are not designed for humid environments. The fabric absorbs moisture, which can lead to mildew, warping, and fabric degradation over time. The Persilux addresses this with a waterproof polyester construction.

We tested these in a bathroom with a large window directly above the shower. After three months of daily steam exposure, the shades show no sign of moisture damage. The fabric repels water droplets and dries quickly.

The 100% blackout claim is accurate for the fabric itself. The single-cell construction with blackout lining blocks light completely. However, as with any cellular shade, light gaps around the edges depend on your mounting approach and measurement accuracy.

Custom sizing is available but note the fabric width runs about 0.16 inches shorter than the ordered size. This is intentional to ensure smooth operation, but it means slightly larger side gaps than you might expect.

The anti-static treatment actually works. Dust and pet hair do not cling to these shades the way they do to standard polyester cellular shades. A quick dusting with a microfiber cloth keeps them looking clean.

Who Should Buy Persilux

Bathrooms, kitchens, laundry rooms, and any high-humidity spaces need waterproof blackout cellular shades. The Persilux fills this niche without sacrificing light-blocking performance.

Anyone frustrated by dust accumulation on standard cellular shades will appreciate the anti-static treatment. These stay cleaner longer with minimal maintenance.

Who Should Skip Persilux

If you want top-down bottom-up functionality, these only operate bottom-up. Also, the custom sizing requires careful measurement. The 0.16 inch width reduction surprises some buyers.

8. BlindsAvenue – Best Light Filtering Cellular Shade

Not every window needs complete blackout. Living rooms, dining rooms, and home offices often benefit from diffused natural light that cellular shades provide while maintaining privacy. The BlindsAvenue excels at this light filtering role.

With nearly 4000 reviews and a 4.6 average rating, these are among the most popular cellular shades on the market. The 9/16 inch single-cell construction provides good insulation without the bulk of double-cell designs.

The fabric filters harsh sunlight into a soft, even glow. During testing, we found these eliminated glare on computer screens while keeping rooms bright and cheerful. The privacy level is sufficient that you cannot see details through the shade from outside.

Installation follows standard cellular shade procedures. Mount the brackets, clip in the headrail, and attach the bottom rail if it comes separate. Most windows take 10 to 15 minutes for a first-time installer.

The color selection is extensive. White and off-white options provide a traditional look, while bolder colors can become design elements. The PVC and polyester construction resists fading better than all-fabric alternatives.

Who Should Buy BlindsAvenue

Anyone seeking light filtering cellular shades for common areas will find excellent value here. These work well in living rooms, dining rooms, kitchens, and offices where complete darkness is not the goal.

The massive review base provides confidence. With nearly 4000 verified purchases, you can trust that these deliver consistent quality.

Who Should Skip BlindsAvenue

If you need true blackout for bedrooms or nurseries, these are not the right choice. The light filtering fabric allows significant light through. For blackout, choose one of the dedicated blackout options in this guide.

9. CHICOLOGY – Slim Profile Blackout Shade

Window depth varies significantly. Older homes often have minimal frame depth, while modern construction sometimes prioritizes wall insulation over window recess. The CHICOLOGY slim 2-inch profile fits where bulkier shades cannot.

The 90% blackout rating is honest marketing. These block most light but are not designed for total darkness. During testing, we could see a faint glow around the edges and some light penetration through the fabric itself in direct sun.

For many applications, 90% blackout is sufficient. Living rooms, kitchens, and offices rarely need complete darkness. The CHICOLOGY provides enough light blocking to reduce glare, protect furniture from UV damage, and provide privacy.

The slim profile does not compromise build quality. The headrail and bottom rail are sturdy, and the honeycomb cells hold their shape. The single-cell construction provides decent insulation despite the compact size.

Safety certification matters for homes with children. The CHICOLOGY meets WCMA and CPSC standards for cordless window coverings. The absence of pull cords eliminates strangulation hazards.

Who Should Buy CHICOLOGY

Windows with limited frame depth are the primary use case. If standard cellular shades are too deep for your window recess, the slim 2-inch profile solves the problem.

Budget-conscious buyers who want partial blackout without premium pricing will appreciate the value. These deliver solid performance at an accessible price point.

Who Should Skip CHICOLOGY

If you need true 100% blackout for sleeping, look elsewhere. These allow too much light for shift workers, nurseries, or anyone sensitive to ambient light during sleep.

10. Changshade Motorized – Alexa Compatible Smart Shades

Smart home integration is increasingly important for window treatments. The Changshade Motorized line brings blackout cellular shades into your connected home ecosystem without requiring professional installation or programming.

The dual-layer blackout fabric blocks light effectively. During testing, we found these created true darkness when fully lowered. The motorized operation ensures consistent positioning without the slight variations that happen with manual shades.

Voice control through Alexa works reliably. Simple commands like “Alexa, lower the bedroom shades” or “Alexa, set living room shades to 50 percent” execute smoothly. The SmartThings and Google Home integrations function similarly.

The app adds convenience features beyond voice control. Schedule automatic opening and closing based on time of day, sunrise and sunset, or custom triggers. This creates the illusion of an occupied home when you are away, adding security.

Installation requires more steps than manual shades. You need to mount the motor housing, connect to WiFi, and pair with your smart home system. Plan for 30 to 45 minutes for the first shade, less for subsequent installations.

Who Should Buy Changshade Motorized

Smart home enthusiasts who want motorized blackout cellular shades with broad compatibility will appreciate the Alexa and Google Home integration. The custom sizing ensures proper fit for your specific windows.

Anyone with hard-to-reach windows or mobility concerns benefits from motorization. The ability to control shades from a phone or through voice commands eliminates physical strain.

Who Should Skip Changshade Motorized

If you need immediate delivery, the 4-5 day shipping time and lack of Prime eligibility may be problematic. Also, the higher price point reflects the motor and smart features, so skip these if you do not need automation.

11. MYshade Motorized – Rechargeable Smart Blackout Shades

Battery-powered motorized shades eliminate wiring requirements but create their own hassles when batteries die. The MYshade Motorized uses a rechargeable battery that lasts approximately six months between charges, solving the disposable battery problem.

The environmental sensors differentiate these from other smart shades. Built-in temperature, humidity, and light sensors enable automatic adjustments based on conditions. When afternoon sun hits the window, the shades can lower automatically to prevent overheating.

True 100% blackout performance comes from the dual-layer cellular construction with blackout backing. Our lux meter showed near-zero light penetration with the shades fully closed. This is genuine blackout, not just room darkening.

The rechargeable battery design is practical. A micro-USB cable connects to the motor housing for charging. You do not need to remove the shade from the window. One overnight charge provides months of operation.

Voice control integration works well with Alexa. Google Home and SmartThings compatibility extends the ecosystem options. The app interface is clean and scheduling is intuitive.

Who Should Buy MYshade Motorized

Environmentally conscious buyers who want motorized shades without disposable batteries will appreciate the rechargeable design. The automation sensors add genuine utility for energy savings and comfort.

Anyone wanting true 100% blackout with smart home integration should consider these. The combination of complete light blocking and intelligent automation is rare in this price range.

Who Should Skip MYshade Motorized

With only 93 reviews, long-term reliability data is limited. If you prefer established products with extensive user feedback, consider the non-motorized options or more established smart shade brands.

12. Graywind Smart – Multi-Protocol Smart Home Shades

Smart home protocol fragmentation frustrates many homeowners. The Graywind supports multiple standards, connecting directly to some Alexa devices and working with hubs for broader compatibility. This flexibility future-proofs your investment.

The 5/8 inch single-cell construction achieves 100% blackout through fabric density rather than double-cell design. This keeps the profile slimmer while maintaining complete light blocking. The beige color we tested looks warm and sophisticated.

The rechargeable motor lasts 3 to 6 months per charge depending on use frequency. The 15-channel remote allows grouping control for up to 15 shades separately or together. This is useful for whole-home automation.

Thermal insulation and sound absorption are notable. The cellular construction creates dead air space that dampens outside noise and insulates against temperature transfer. We measured a meaningful reduction in street noise during testing.

Customer service responsiveness stands out. Several reviews mention helpful support for troubleshooting connectivity issues. Smart shade installation can be challenging, so good support matters.

Who Should Buy Graywind Smart

Smart home users with mixed ecosystems will appreciate the multi-protocol support. Whether you use Alexa, Google Home, or HomeKit, these integrate without requiring specific hub brands.

The quiet operation makes these suitable for bedrooms where motor noise could disturb sleep. While not silent, the motor is noticeably quieter than many competitors in this price range.

Who Should Skip Graywind Smart

The setup complexity requires some technical comfort. If you struggle with smart home device configuration, consider simpler options or budget for professional installation. Also, some Alexa integrations require specific Echo models or additional hubs.

Buying Guide: How to Choose the Best Blackout Cellular Shades

Selecting the right blackout cellular shades requires understanding several key factors that affect performance, installation, and daily use. Our testing revealed significant differences between products that look similar on the surface.

Inside Mount vs Outside Mount

Inside mount places the shade within the window frame for a clean, built-in appearance. This looks more finished but creates small light gaps on the sides where the shade is slightly narrower than the opening. Outside mount attaches to the wall or trim above the window, overlapping the frame by several inches to eliminate side light leaks.

For true blackout, outside mount is generally superior. The overlap prevents the light halo effect that occurs when light sneaks around the edges of inside-mounted shades. However, inside mount preserves views of decorative trim and looks more integrated.

Cordless vs Motorized

Cordless blackout cellular shades use spring-loaded mechanisms or manual push-pull operation. They are safer for homes with children and pets, eliminate dangling cords, and provide a cleaner look. Motorized options add convenience and smart home integration but cost significantly more.

For most bedrooms and living spaces, cordless operation provides the best balance of safety, aesthetics, and value. Motorization makes sense for hard-to-reach windows, home theaters, or smart home enthusiasts who want automated schedules.

Single Cell vs Double Cell Construction

Single-cell shades use one layer of honeycomb cells. They provide good insulation and cost less. Double-cell construction stacks two layers of cells, creating additional dead air space for superior thermal and acoustic insulation.

For blackout purposes, either construction works if the fabric includes blackout lining. Double-cell shades offer better energy efficiency but cost more and have a deeper profile that may not fit shallow window frames.

Cellular vs Honeycomb Shades

These terms describe the same product. The honeycomb-shaped cells that trap air are sometimes called cellular construction. Whether labeled cellular shades or honeycomb shades, the technology is identical. Both use hollow cells to create insulation.

True blackout cellular shades add light-blocking fabric layers to the honeycomb structure. Standard cellular shades only filter light. Check opacity ratings carefully when ordering.

Side Track Systems for True Blackout

The biggest challenge with blackout cellular shades is light halo. Even with blackout fabric, light leaks around the edges of the shade. Side track systems seal these gaps with channels that the shade edges slide into.

These systems require outside mount installation and add cost, but they achieve near-absolute darkness. For home theaters, photography darkrooms, or shift workers who sleep during daylight, side tracks are worth considering.

Measuring Tips for Perfect Fit

Always measure twice before ordering custom blackout cellular shades. For inside mount, measure the width at the top, middle, and bottom of the window opening. Use the narrowest measurement. For height, measure left, center, and right, using the longest measurement.

Most manufacturers deduct 1/8 to 3/8 inch from the ordered width to ensure the shade fits within the opening. Factor this into your calculations if you want minimal side gaps. When in doubt, order slightly narrow for inside mount or slightly wide for outside mount.
