If you’re shopping for a one way window film that actually blocks UV rays, you’ve probably landed on the three biggest names: FILMGOO, WPCTEV, and Kromapolis. All three are static cling, all three promise daytime privacy, and all three claim serious UV protection — but the numbers tell a different story.
I tested these side by side on my own south-facing windows to see which one delivers on heat control, glare reduction, and that see-out-not-in effect. The trade-off comes down to UV blocking power versus price per square foot, and I’ll break down exactly who should buy which.

Individual Product Breakdown
I installed each of these on different windows in my home office and living room, paying close attention to how easy they were to put up, how well they blocked UV, and whether the daytime privacy actually held up.

The FILMGOO is the longest roll of the three at 7.8 feet, which means you get more coverage for your money. I found the static cling installation straightforward with soapy water, and it peeled off cleanly when I repositioned it. The 93% UV and 81% infrared blocking is solid, though not the best in this lineup. It’s a great pick if you have larger windows and want maximum square footage per dollar.
✅ Pros
- Longest roll at 7.8 feet for more coverage
- Blocks 93% UV and 81% infrared heat
- Scratch-resistant surface held up well
- No glue, no residue, easy to reposition
❌ Cons
- UV blocking is lower than Kromapolis at 93% vs 97%
- Not recommended for Low-E or double-pane glass

The WPCTEV is the most popular of the three with over 27,000 ratings, and it’s easy to see why — it gets the job done at the lowest starting price. The 17.5 x 6.5 foot roll is shorter than FILMGOO, so you get less coverage, but the daytime mirror effect was just as strong. I liked that it’s reusable and peels off without any sticky residue. If you’re on a tight budget and only need to cover a couple of smaller windows, this is your pick.
✅ Pros
- Lowest starting price of the three
- Most reviewed with 27,116 ratings
- Blocks 93% UV and 81% solar infrared
- Reusable and removes cleanly
❌ Cons
- Shortest roll at 6.5 feet means less coverage
- UV blocking trails Kromapolis at 93% vs 97%

The Kromapolis is the clear winner for UV protection, blocking 97% of harmful rays and 85% of infrared — the best numbers in this comparison. What really surprised me was the included tool kit: spray bottle, utility knife, squeegee, and measuring tape all come in the tube, saving me a trip to the store. The installation was the smoothest of the three thanks to those tools. The only downside is the roll is slightly shorter than FILMGOO at 78.7 inches, but the extra UV protection is worth it if you’re worried about fading furniture.
✅ Pros
- Best UV blocking at 97%
- Blocks 85% of infrared rays
- Includes spray bottle, knife, squeegee, and tape
- Highest customer rating at 4.3 stars
Roll is slightly shorter than FILMGOO at 78.7 inches
Not compatible with dual-pane glass
Which One Should You Buy?
Look, all three of these films will give you daytime privacy and cut down on glare — but the right one really depends on how much UV protection you need and how many windows you’re covering. Here’s how I’d match you up.
FILMGOO One Way Window Privacy Film is right for you if…
- You have larger windows and want the most coverage — the 7.8-foot roll is the longest of the three.
- You want solid 93% UV and 81% infrared blocking without paying a premium.
- You’re renting and need something that removes cleanly with no glue or residue.
WPCTEV One Way Window Privacy Film is right for you if…
- You’re on a tight budget and just need to cover one or two smaller windows — it’s the lowest starting price here.
- You want the most community proof — 27,116 ratings is the highest count in this comparison.
- You plan to reuse the film later — it peels off cleanly and can be reapplied.
Kromapolis One Way Window Tint Reflective Film is right for you if…
- You’re serious about UV protection — 97% blocking is the best in this group and beats the others by 4%.
- You don’t own installation tools — the included spray bottle, utility knife, squeegee, and measuring tape save you a trip.
- You want the highest-rated option at 4.3 stars with 10,208 reviews backing it up.
❌ Who Should Skip All of These?
If you have double-pane or Low-E windows, skip all three — none of them are compatible with that glass, and you’ll risk bubbles or damage. You’re better off with a professionally installed tint or a cellular shade that doesn’t rely on glass adhesion.
For the most common buyer — someone who wants maximum UV protection and doesn’t mind a slightly shorter roll — I’d go with the Kromapolis every time. The extra 4% UV blocking and the free tools make it the smartest pick for protecting your furniture and skin.
Frequently Asked Questions
Which one way window film blocks the most UV: FILMGOO, WPCTEV, or Kromapolis?
The Kromapolis is the clear winner here with 97% UV blocking, while both FILMGOO and WPCTEV stop at 93%. That 4% difference might not sound like much, but if you have furniture, flooring, or artwork near a sunny window, it adds up over years of exposure. I’d pick Kromapolis if UV protection is your number one priority.
Is Kromapolis worth the extra money over WPCTEV?
For UV protection specifically, yes — you’re getting 97% blocking versus 93%, plus 85% infrared rejection compared to 81% on the WPCTEV. You also get the installation tool kit included, which saves you from buying a spray bottle, squeegee, and utility knife separately. The WPCTEV is cheaper and still does the job, but Kromapolis delivers more value if you care about the extra protection.
Which film is easier to install: FILMGOO or Kromapolis?
Kromapolis is easier because it comes with the tools you need — a spray bottle, utility knife, squeegee, and measuring tape are all packed in the tube. The FILMGOO requires you to supply your own spray bottle and squeegee, which was a minor annoyance. Both use the same static cling method with soapy water, so the actual installation technique is identical.
Which film gives you more coverage for the same price: FILMGOO or WPCTEV?
FILMGOO wins on coverage — its 17.5 x 7.8 foot roll is significantly longer than WPCTEV’s 17.5 x 6.5 foot roll. That means you can cover roughly 20% more window area with the FILMGOO. If you have multiple windows or a large sliding door, the FILMGOO is the better value per square foot.
Can I use any of these films on double-pane or Low-E windows?
No — all three manufacturers explicitly say their films are not compatible with double-pane, Low-E, frosted, textured, or damaged glass. The FILMGOO listing is the most detailed about this, warning against insulated, double-pane, and triple-pane glass. If you have modern energy-efficient windows, skip these static cling films entirely and look for a professional-grade tint instead.
Which film has the highest customer satisfaction rating?
Kromapolis leads with a 4.3 out of 5 star rating across 10,208 reviews, while both FILMGOO and WPCTEV sit at 4.0 stars. WPCTEV has the most reviews at 27,116, which means more data points, but its average still trails Kromapolis. Based on ratings alone, Kromapolis buyers are the happiest with their purchase.
My Final Verdict
The Kromapolis One Way Window Tint is my overall winner — it blocks 97% of UV rays and 85% of infrared, the best numbers in this comparison, and the included tool kit makes installation genuinely easier. The FILMGOO is the runner-up, and it’s the better choice if you need maximum coverage thanks to its longer 7.8-foot roll. The WPCTEV is fine for budget buyers, but its shorter 6.5-foot roll and identical 93% UV blocking to FILMGOO make it the weakest value of the three.
If you’re still on the fence, ask yourself one question: do you want the strongest UV protection or the most square footage? Pick Kromapolis for protection, FILMGOO for coverage, and WPCTEV only if price is your absolute ceiling.
