Where do you put your air freshener in the car? I normally use the Japanese brand "Glare" which fits perfectly in cup holder. But there is no cup holder near the a/c. I am about to pick up my 2016 Rav4 Hybrid Limited.
We used to use one in our car but found that whatever chemicals were in it had a detrimental effect on my wife's asthma. She found it made her feel wheezy especially after a long trip. I removed it and within a couple of weeks or so she didn't have that problem after a car journey. Of course it might well have been just a coincidence but I am not going to risk it as it's quite scary being with an asthmatic who is having worse breathing problems than she usually has.
