- Magnetic or Metal Covers: These cover the chimney opening from the inside or outside and can be very effective but sometimes pricier.
Key Features I Looked For
When shopping, I focused on these important features:
- Size and Fit: My chimney has specific dimensions, so I measured carefully to ensure the draft stopper would fit perfectly without gaps.
- Material Quality: I preferred durable, fire-resistant materials since the stopper would be near heat.
- Ease of Installation and Removal: I wanted something I could easily put in place before winter and remove when using the fireplace.

- Reusability: I looked for products that I could use year after year without losing shape or function.
Additional Tips From My Experience
- Always measure your chimney flue’s width and height before ordering a draft stopper.
- Check if the product comes with clear instructions or customer support if you run into installation issues.
- Consider the appearance if your chimney is visible inside your home—I preferred a draft stopper that looked neat and unobtrusive.
- If you use your fireplace often, choose a stopper that’s quick to remove and reinstall.
