Hey, I would like to get feedback about this filter. I also need to change the filter, but I don't know which one is better. What do you recommend? I also have a question about the ozone generator. If someone used it to disinfect the car and get rid of the unpleasant odor, share your experience. I recently read an article on Damage Control-911 and think this is a good way to solve these problems. Do you have a personal ozone generator or did you order this service at a car wash? I am interested to find out if this really works and what is more profitable-to buy your own generator or order this service?
