How much does a home water filtration system cost?
A home water filtration system typically costs between $25 and $75 per month with financing (subject to credit approval), or can be purchased outright. With Puragain, that price includes professional installation and a lifetime service plan — not just the equipment.
What drives the cost
The two biggest factors are the type of system (a point-of-use reverse-osmosis unit costs less than whole-house treatment) and your home — its size, plumbing, and installation complexity.
Puragain pricing
Reverse osmosis starts around $26/month, the 6-stage alkaline system around $42/month, and whole-house treatment around $74/month — all with zero money down, subject to credit approval. Systems can also be purchased outright.
What's included in the price
Every system includes free professional installation, a 7-year warranty, and a lifetime service plan: annual filter changes, annual water testing, annual maintenance, and unlimited service calls. That ongoing service is a real part of the value, not an add-on.
Filtration vs. bottled water
Households that buy bottled water often spend more over a few years than a filtration system costs — with the added hassle of hauling and storing cases, and the plastic waste. Filtration gives you unlimited clean water from your own tap.
