Light filtering cellular shades soften incoming daylight while offering more privacy than an uncovered window. The BlindsAvenue top-down/bottom-up shade is best for buyers seeking flexible light control; its standard cordless shade suits shoppers who need a specific 27-inch width. Joydeco is a candidate for a 26-by-64-inch window, while the thermal-insulation shade and LazBlinds model fit different size and feature priorities. Measure carefully before choosing: the listed models have fixed dimensions.
| Shade | Listed Size | Best For |
|---|---|---|
| BlindsAvenue TDBU | 28 × 72 inches | Top-down/bottom-up operation |
| BlindsAvenue Cordless | 27 × 72 inches | Windows matching its mount requirements |
| Joydeco Cordless | 26 × 64 inches | Buyers seeking a light-filtering shade |
| Cordless Thermal Insulation | 22 × 48 inches | Smaller windows and thermal-insulation priority |
| LazBlinds Cordless | 34 × 36 inches | Short windows and adjustable height |
BlindsAvenue Cordless TDBU Cellular Shade

Best for: Buyers who want a 28-by-72-inch white shade identified as top-down/bottom-up (TDBU). The TDBU designation makes this a suitable option to compare when adjustable coverage from the top or bottom is a priority.
The listed product name also identifies it as cordless and cellular. Choose this model if those features and its stated size match your needs. The provided product information does not specify fabric composition or detailed measuring allowances, so confirm fit and operation details before ordering.
BlindsAvenue Cordless Cellular Shade

Best for: Buyers whose window measurements work with this 27-by-72-inch white shade. Its listed material is 100% polyester, and the product includes separate sizing guidance for inside and outside mounts.
For an inside mount, the seller says to order the shade 1/4 to 1/2 inch narrower than the opening. It specifies that this shade fits openings from 27-1/4 to 27-1/2 inches wide for an inside mount. For an outside mount, order the width of the area to cover. The limitation is its narrow stated inside-fit range; measure precisely before choosing it.
Joydeco Cordless Light Filtering Cellular Shade

Best for: Shoppers looking for a white cordless light-filtering shade in a 26-by-64-inch size. The title directly identifies the light-filtering function, making this a relevant option for rooms where softened daylight is the goal.
Choose it if the listed dimensions suit your window and you want a cordless design. The supplied product details do not provide material, mounting instructions, or specific privacy performance. Check the listing for those details and verify the shade dimensions against your installation plan.
Cordless Thermal Insulation Cellular Shade

Best for: Buyers with a smaller 22-by-48-inch window who prioritize a product described as thermal insulation. The listing name also identifies it as cordless and white, making it a size-specific alternative to the larger options.
Choose this model if those stated attributes match your priorities. The provided information does not explain the fabric’s light-filtering level or provide mounting measurements. Confirm how the shade handles light and how to size it before buying, especially if daytime privacy is important.
LazBlinds Cordless Cellular Shade

Best for: Buyers who want a 34-inch-wide shade with height adjustable from 0 to 36 inches. The seller describes its soft polyester fabric as light filtering: it allows soft light into a room while providing privacy. The listed cordless design raises and lowers by hand.
For inside mounting, the seller recommends choosing a size the same as or closest to the window width. For outside mounting, it recommends a shade 3 to 5 inches wider than the window. Avoid this choice if your window is taller than the stated 36-inch adjustment range or if its width does not suit the fixed 34-inch listing.
Buying Guide: How To Choose Light Filtering Cellular Shades
What does light filtering mean?
Light-filtering fabric is intended to soften daylight rather than block all incoming light. It can offer privacy while allowing some light through, but privacy varies with fabric and lighting conditions. The LazBlinds listing specifically describes soft light and privacy; for products without comparable details, verify the fabric description before purchase. Light filtering is not the same as blackout.
How should you measure for a cellular shade?
First decide whether the shade will sit inside the window frame or cover it from outside. Measure the window opening carefully and follow the product’s own sizing instructions. The BlindsAvenue 27-inch model gives a specific inside-mount opening range, while LazBlinds recommends extra width for outside coverage. Do not assume all brands use the same deductions or sizing rules.
Which size and features matter most?
- Match dimensions: Compare the listed width and height with the window and mounting plan before selecting a model.
- Consider operation: Cordless options are listed across the products; the 28-by-72-inch BlindsAvenue model is specifically labeled TDBU.
- Prioritize stated functions: Choose a clearly described light-filtering model for softened daylight or consider the thermal-insulation product if that named feature is important.
- Check missing details: Confirm material, installation hardware, light control, and fit information when the supplied description does not specify them.
Frequently Asked Questions
Do light filtering cellular shades provide privacy?
They can provide privacy while allowing softened light, but the level depends on fabric and lighting. Check the product description for explicit privacy details.
Do light filtering shades make a room completely dark?
No. Light filtering is designed to admit some light. Choose a product described as blackout if blocking light is the priority.
How much wider should an outside-mount shade be?
It depends on the product and desired coverage. LazBlinds recommends adding 3 to 5 inches to the window width; follow the chosen model’s instructions.
Are cordless cellular shades adjustable?
The LazBlinds listing says its shade can be raised or lowered, with height adjustable from 0 to 36 inches. Check each product’s details for its specific operation.
What is a TDBU cellular shade?
TDBU means top-down/bottom-up. The BlindsAvenue model is identified by that term in its product name; confirm its operating instructions and fit details before ordering.
