Query: High quality bags!

I will never buy another vacuum bag as long as these exist! I have 2 dogs and 2 cats, so I have to vacuum ALOT and these have completely changed how well our vacuum works. The light on our Windtunnel vacuum that senses dirt, gets and stays to green much longer, so I am not having to go over areas as much. My sinuses arent bothering me as much after cleaning. It's crazy one could like a vacuum bag this much, haha! Oh, and the price is amazing for the quantity!
