Reverse Osmosis vs. Whole-House Filtration

Reverse osmosis (RO) is a point-of-use system, usually under the kitchen sink. Its membrane filters water far below a micron, removing dissolved solids and reducing lead, PFAS, microplastics, and many other contaminants for premium drinking and cooking water at one tap.

Whole-house filtration is point-of-entry — it treats all the water coming into your home, reducing chlorine, chloramine, sediment, taste and odor at every faucet and shower, but it doesn't remove dissolved solids the way RO does.

So which do you need?

They're complements, not competitors. Whole-house filtration protects your skin, hair, fixtures and appliances and improves water everywhere; reverse osmosis gives you the cleanest possible water for drinking and cooking. Many Central Texas homes run a softener plus whole-house filtration plus a kitchen RO unit for complete coverage. Testing tells us which contaminants you actually have so nothing is over- or under-built.
