How airtight are Freedom Pet Pass pet doors? These pet doors have an "unflappable" flap with an airtight seal that will not blow open or allow drafts, moisture or insects to get in.
Seeing is believing. Check out this short but dramatic Freedom Pet Pass demo video.
A Freedom Pet Pass dog door may cost a little more than other brands but in the long run (60 months as determined by independent testing) you'll recoup the extra cost with money saved on home energy bills.
Other notable features: extremely quiet and safe for your pet; only non-toxic materials are used; no sharp inside corners, springs, pins or mechanical hinges that can harm your pet.
