Filterbaby is currently compatible with ~98% of US faucets with a circular removable aerator! Your kit comes with 10 adaptors to help fit different faucet sizes.

If you are still unsure about whether the filter will fit, please contact us and we gladly help. We also have a 60-day refund policy for all orders in the case that none of the provided adaptors fit. 

FilterBaby will NOT fit faucets that are square shaped, pull out, hand-held, spray-style, or faucets with a sensor.

We're here to help! We have extra specialty adaptors we can provide for free. Contact us for help ASAP!

Most standard sink aerators are easily twistable by hand, if you're having difficulty a wrench or or pliers will do the trick.

Hidden aerators need to be removed using aerator keys which are provided in your starter kit. 

If you're still having difficulty please contact us and we're happy to help.
