How tall are the canisters? (Pictures appear small, but picturs are also deceptive!)

The filters themselves are 8in long. The canister body is approximately 9in. The overall height of the unit is approximately 13in tall. Hope this helps.

can this be installed outside (in a non-freezing environment)?

Can this unit be used in a condo?

Hi, Thanks for your interest in our whole house filter product. Since this filter uses 1" fitting, if it can be connected to your current water line, it should be able to use in a condo. If you have contacted us via email but received no reply, please check the Spam/Junk Folder first. Thank you. If you have any other inquiries, please feel free to contact us. 1-888-352-3558 Kind Regards Mia Lauren Customer Service Rep

Is the filter delivered alongside the machine, or do I need to buy the filter separately?

Dear Sandra, Thank you for your inquiry. The system comes with two filters – a PP cotton filter and an activated carbon filter. The PP filter requires replacement every 3-6 months. The GAC filter requires replacement every six months. We recommend buying extra filters for an emergency and here is the link for your reference: https://www.amazon.com/dp/B08RHLWQ6N I hope this information may help you. Please feel free to let us know if you have any other questions. Thank you. Kind Regards, Mia Lauren Customer Service Rep
