If you want better air quality in your home and you have a cat or multiple cats, you always will want to change the litter box when it gets full.
By not changing the litter box not only will your cats crap all over your home, but it will always make the air quality very bad and almost dangerous after a while! I used to be lazy in changing the litter box for my cats. But after I got tired of feeling sick from that ammonia type smell killing the air quality in my home, I decided it was time I step things up and make the extra effort to always clean the litter box every other day even if it isn’t full. It is better to take that extra precaution than to be sorry later and have serious air quality issues. Just because I have cats and in addition to the litter box other things can cause bad air quality, I went out and invested in a whole home air purification system for my home. The whole home air purification system really makes things better all around as long as I remember to clean that litter box every few days or so. That makes it so that all the whole home air purification system has to contend with is the pet hairs and such. This makes it much easier for the whole home air purification system to do its job and do it very well! I would not want to have it any other way than this for sure.
