Whole-house and under-sink water filters solve different problems. One is not automatically better than the other; the right choice depends on where you want filtered water and what you want removed.
Whole-house filters
A whole-house water filter is installed near the point where water enters the home. That means the kitchen, bathrooms, laundry and appliances can all receive filtered water. This is the stronger fit when buyers are searching for every-tap filtration, chlorine smell reduction, sediment control or whole-home PFAS reduction.
Under-sink filters
An under-sink filter usually treats water at one tap, most often the kitchen. It can be a good choice when the main concern is drinking and cooking water, not showers, bathrooms, laundry or appliances.
Cost and install differences
Whole-house systems are usually higher cost and more installation-heavy. Under-sink systems are usually cheaper and simpler. That is why Google Ads should keep these intents separate until both product ranges are live.
Which buyer should choose whole-house?
Whole-house filtration is the better fit for homeowners who want one system working before water reaches the kitchen, bathrooms, laundry and outdoor taps. It also suits buyers who are thinking beyond drinking water: shower feel, chlorine smell, sediment in fixtures, appliance protection and family-wide water use are all part of the decision.
It is also the cleaner fit for higher-consideration concerns like PFAS, because the buyer is usually asking whether every tap can be covered rather than whether one drinking-water outlet can be improved. The trade-off is that the system needs proper placement, enough flow rate for the home and licensed installation.
Which buyer should choose under-sink?
Under-sink filtration is usually the right call when the buyer only cares about drinking and cooking water from one tap. It can be more affordable, simpler to install and easier to compare. It does not solve whole-home water concerns, and it is not the product intent we should push from the current AquaCo launch collection.
Current Home Harvest Hub recommendation
The current launch product is a whole-house product, so the main collection should target Whole House Water Filters. Under-sink terms should be treated carefully in ads unless an under-sink range is ready.
