How will I know when to change my filter?Updated a year ago
There is no exterior indication that the filter needs to be changed, but you can estimate when it needs to be changed based on how often you are filling it. The top reservoir holds about 1/2 gallon and the life of the filter is 100 gallons. If you fill the top reservoir twice a day, you’re filtering about one gallon per day. In that case, the filter would need to be changed in 100 days, or just over three months.*
