03 / FAQ

Good to know.

Do passive vents need electricity?

No. The passive BigAir wall vents and Sky Light roof vent have no powered fan.

What is the difference between fan only and a bundle?

A fan-only listing contains the fan described on its product page. The bundles shown here pair a fan with intake vents; some include screen mesh. Check the exact Amazon listing before ordering.

Will a US Amazon link take Canadian shoppers to Amazon.ca?

Amazon OneLink can offer local matches when an applicable local listing and Associates setup are available. The destination is controlled by Amazon; check the final listing and delivery options for your location.

Why are prices shown on Amazon rather than here?

Amazon pricing and availability change. Use each product's Amazon button for the current offer in your region.
