I have two cats, two dogs, am 8 year old child, and a 9 year old child. I cannot believe how awesome these are! I often use vinegar to clean out any odor build up. I thought it was doing ok...then I tried one of these. My entire house smelled good every load of laundry that I washed for the next week. I was concerned that the scent might mean a lot of chemicals - but my daughter and I both have sensitive skin and there have been zero issues. No irritation.
