Research preview

Sleep with the window open. Hear less of the street.

A window insert we're designing to let fresh air in while taking the edge off voices, dogs and neighbors' AC. It fits the window you have, so it works for renters too.

Expected price$349
Reserve for $1 (fully refundable)

In development. No noise claims until it's tested.

FAQ

Is it available now?
No. Aerolull is in research preview. It hasn't been built in final form or lab-tested yet.
What does the $1 do?
It holds your place for the first production run. It's fully refundable. Just reply to your receipt email.
How much quieter will it be?
We don't know yet, and we won't guess. We'll publish measured results once it's tested. It's meant to take the edge off, not to make a room silent.
Will it fit my window?
We're designing for common sliding, double-hung and casement windows, with no tools and no changes to the frame.
Why $349?
That's our expected price for the powered insert. You'll get the final price before you're asked to pay it.

If you reserve, we keep your email, any optional answers (window type, own or rent, main noise source), the date, your approximate country, and which link or campaign brought you here. Payments are handled by Stripe, and we never see your card details.
