When buying a sunshade, Ultraviolet Protection Factor (UPF) is the most critical factor for blocking harmful UV rays. But how can you verify if a sunshade truly offers high UPF protection?
This guide covers:
✔ Understanding UPF ratings
✔ Key features of high-UPF sunshades
✔ How to test UPF at home
✔ Common scams to avoid
1. What is UPF? (Ultraviolet Protection Factor)
UPF measures how much UV radiation a fabric blocks:
UPF Rating | UV Blocked | Protection Level |
---|---|---|
UPF 15-24 | 93.3%-95.9% | Good |
UPF 25-39 | 96.0%-97.4% | Very Good |
UPF 40-50+ | 97.5%-98%+ | Excellent |
✅ For maximum protection, choose UPF 50+.

2. How to Check if a Sunshade is Truly UPF-Rated?
✔ Look for Certified Lab Testing
Legitimate UPF claims are backed by third-party lab tests from:
- Australia/New Zealand (AS/NZS 4399)
- Europe (EN 13758)
- USA (ASTM D6603)
⚠️ Red Flag: If a label says “UV protection” but has no UPF number or certification, it may not be reliable.
✔ Examine Fabric Quality
- Tightly Woven Fabric (less light passes through)
- Dark Colors (black, navy absorb more UV than light colors)
- Special Coatings (titanium dioxide, silver reflective layers)
Quick Test: Hold the fabric up to bright light—if you see lots of tiny light dots, UPF is likely low.

3. How to Test UPF at Home (Simple Methods)
Method 1: UV Test Card
- Place the card in direct sunlight (note the color change).
- Cover it with the sunshade—less color change = higher UPF.
Method 2: Flashlight Test
- Shine a bright flashlight from inside the shade.
- If minimal light passes through, the UPF is likely high.

4. Common Sunshade Scams to Avoid
❌ “Black Fabric = High UPF” – Some cheap black fabrics lack UV-blocking tech.
❌ “Waterproof = UV Proof” – Water resistance ≠ sun protection.
❌ “No Certification Needed” – Always demand lab-tested UPF ratings.
5. Best High-UPF Sunshades (Tested & Trusted)
- Coolibar UPF 50+ (Certified for extreme sun)
- Sunny Parasol ProShade (Military-grade UV blocking)

Final Tip: Check the Warranty
A 5+ year warranty often indicates confidence in long-term UV resistance.
