An old filter isn't filtering. A subscription fixes that for good.

Our take
An old filter can be worse than no filter
We make whole-house systems with our own manufacturers and wholesale to water companies, and the same standards go into our store products.
Filters don't fail loudly. They just quietly stop working. A spent carbon filter stops removing chlorine, and a clogged one drops your water pressure. Old cartridges can even let trapped particles back through.
That's why we push subscriptions. Not to sell more filters, but because nobody remembers a 6-month schedule. The filters show up, you swap them in a few minutes, and your water stays the way it was on day one. If you'd rather not swap them, a partner plumber can do it.
