How do I know when to replace my Mila filter?

We typically recommend changing your filters every six months, which we make as easy as possible for you when you sign up for Auto-Refill. Auto-Refill gets you a fresh new filter every six months, which you can pause, skip or cancel at any time. That said, how long your filter lasts will depend on your home’s environment and other factors such as overall air quality in the region, incoming pollen levels, ozone or wildfire smoke that could affect overall air quality etc. Be on the lookout for upcoming product releases that will give you more insight into the factors affecting your home’s air quality, overall health, and your filter life.
