If you are not sure which configuration to choose, use this as a starting point before digging through every variant.

Still unsure? Call (855) 786-5010 or email sales@homesteadheavy.com and we will help you sanity-check the fit.

Important: Whole-house RO should be matched to your water test results, pressure, flow needs, and installation space. If your water has heavy sediment, iron, bacteria, hardness, or very high TDS, confirm the right pre-treatment before buying.

Most whole house filters remove specific contaminants. Reverse osmosis removes nearly everything -- dissolved salts, heavy metals, fluoride, nitrates, chlorine, chloramines, pesticides, pharmaceuticals, and hundreds of other dissolved solids. The Crystal Quest Whole House RO System takes that purification level and scales it to your entire home, not just a single tap. With 9 flow rate options from 300 GPD to 7,000 GPD, this system is sized for anything from a small off-grid cabin to a large home with 5+ bathrooms.

Every system is factory-tested before shipping and arrives operational. Prefilters extend membrane life. As long as prefilters and membranes are replaced on schedule, these systems are designed to run 15-20 years.

Important note on RO water: Reverse osmosis removes minerals from water, which can lower pH and potentially affect plumbing and taste over time. The optional remineralizer add-on adds essential minerals back and raises pH -- recommended for whole-home installations.

Not Sure Which Whole-House RO System Is Right?

A whole-house reverse osmosis system has to match your water source, household size, bathroom count, flow needs, storage tank space, and installation plan. Guessing wrong can mean poor pressure, wasted money, or a system that does not fit your property.

Talk to us before you buy. We will help you sanity-check the right GPD rating, tank configuration, pump option, and add-ons for your home or off-grid setup.

What Buyers Say About the Crystal Quest Whole House RO System

These reviews come from Crystal Quest whole-house RO customers. They are useful because they point to the real buying questions: support, installation, delivery, and what happens if something needs fixing.

"Crystal Quest was great to work with. The system arrived without some of the install documentation but after a call they sent me the documentation and helped me with the installation."

Jacob P.

"The staff of Crystal Quest is great. Any time I called in they answer all my questions and make me feel confident about my purchase. Love the system."

Crystal Quest customer

"So far so good, was delivered quickly and accurately. Easy to install with some experience."

Normand Roberge

"Overall quality of the product is quite decent. The installation manual doesn't mention that there is a need to flush the system for 30 minutes before drinking the water, but the customer service was able to guide me through that."

Pierre-Etienne Durand

"I was surprised when I turned on the unit for the first time that water started leaking from carbon filter. Called Crystal Quest and they immediately sent me a replacement. Great customer service."
