I'm trying to solve this problem myself, and I was hoping to find some answers here. And there are more questions than answers. To update my post, I want to add that sometimes I wish I was born a boy, because I can't do many men's chores. Well, I raise my children alone and use every opportunity to save money, so I sometimes do minor car repairs myself, watching videos on YouTube. By the way, thank you for the scheme you sent me! I appreciate it. And I have a question, while searching for a new air filter on Amazon, I found ozone generators. I studied information about them on the Internet and read the instructions on https://www.damagecontrol-911.com/ozone-generators-in-the-car/. I want to ask if you know anything about this, please advise whether I should order it to make the air in my car clean and fresh.
