I am worried about the filter

I remember it was only a few weekends ago, our husband and myself went to go see a new film that just came out at the cinema. That multiplex sure was packed. I can never get over the prices they charge for drinks and popcorn! It seems completely crazy to pay the same price as I would pay for a delicious steak supper for some movie snacks. Well, they actually get away with it because people like me buy plenty of popcorn and chips, like for our husband and I. While all of us were watching the movie, all was going well and it was a very great film! Unfortunately, they experienced some sort of tech malfunction with the air conditioner system in the theatre. It started to get undoubtedly very warm as all of us were in the Summer season. It must have been 95 degrees outside. The cinema was definitely cool when all of us walked in, however in the middle of that film it was incredibly warm and humid inside! I couldn’t rest it anymore because it was ruining the whole film for us. Both of us made complaints and got our money back. They also provided us free passes to our next film. I was still mad about the air conditioner system breakdown spoiling the ending of the film; I didn’t even get to watch the whole thing! I got over it though and was at least pleased about the free tickets. Both of us went back the following weekend to the same cinema. I thought it was smart for them to supply us free tickets, because they knew all of us would be coming back again. With us coming back… all of us bought more chips and popcorn for a massive price again! That’s how they get you… Well the air conditioner was sure fixed in the cinema and I was undoubtedly gleeful with the air quality. I was pleased with the whole cinema experience even though I had to watch the film all over again.
