Choosing the Right Water Filtration System for Your Central Washington Home: Whole House vs. Under Sink Systems

Many homeowners in the Yakima Valley face the decision of investing in water filtration systems to ensure clean, safe, and fresh tasting water. Two popular options are whole house filtration systems and under-sink systems. In this blog post, we’ll explore the differences between these two options and help you make the right choice for your Central Washington home.

Whole House Filtration Systems


  1. Comprehensive Coverage: Whole house filtration systems filter water at the main entry point, ensuring that every tap and fixture receives treated water. This is especially beneficial in Central Washington, where water quality can vary across the county and you want peace of mind.
  2. Minimizes Contaminant Exposure: With a whole house system, you’ll be reducing exposure to contaminants in your shower, washing machine, and even the garden hose. This is important for both your health and the longevity of appliances.
  3. Convenience: No need for individual filters at every tap. You can enjoy clean water without the hassle of managing multiple filter units.
  4. Longevity: Whole house systems often have longer filter lifespans compared to under-sink systems. This means fewer replacements and less maintenance.


  1. Cost: Whole house systems can be more expensive upfront, which might not be feasible for everyone.
  2. Professional Installation: These systems usually require professional installation, adding to the initial cost.
  3. Space Requirement: You’ll need ample space to install a whole house system, including a dedicated spot for the unit and access to your main water line.

Under-Sink Water Filtration Systems


  1. Affordability: Under-sink systems are typically more budget-friendly than whole house systems, making them a suitable option for homeowners looking for a cost-effective solution.
  2. Easy Installation: Many under-sink systems are designed for DIY installation, saving you money on professional installation fees.
  3. Customization: You can choose under-sink systems with specific filters tailored to your water quality concerns, like sediment, chlorine, or lead. This customization can be especially helpful in Central Washington, where water conditions can vary widely.
  4. Saves Space: These units are compact and fit conveniently under your kitchen sink, not taking up much space.


  1. Limited Coverage: Under-sink systems only filter the water at the point of use. While they ensure clean drinking and cooking water, they don’t address water quality issues in other areas of your home.
  2. Maintenance: Filters need to be replaced regularly, and this can be more frequent compared to whole house systems. Over time, this may add up in terms of costs and maintenance effort.
  3. Not Ideal for Hard Water: If your concern is hard water, under-sink systems might not be the most effective solution. Whole house systems or water softeners are better for tackling this issue.

Choosing between a whole house filtration system and an under-sink system in Central Washington ultimately depends on your priorities and needs.

Consider these factors when making your decision:

1. Water Quality Concerns: If you’re mainly worried about drinking water, an under-sink system might suffice. However, if you want to address issues in showering and appliance usage as well, a whole house system is more appropriate.

2. Budget: Assess your budget and decide how much you’re willing to invest in water quality. Remember that whole house systems have higher upfront costs will save you money in the long run.

3. Installation and Maintenance: Think about whether you’re comfortable with DIY installation and regular filter replacements. If not, a whole house system with professional installation might be more suitable.

4. Available Space: Consider the available space in your home. If you lack the room for a whole house system, an under-sink unit is a more space-efficient option.

5. Water Quality Variation: Central Washington’s water quality can vary by location. If you live in an area with consistent water issues, a whole house system might be more appealing. In areas with better water quality, an under-sink system could suffice.

In Central Washington, where beautiful landscapes meet water quality challenges, choosing the right water filtration system is crucial. Both whole house and under-sink systems have their merits and downsides, and your decision should align with your specific needs, budget, and the water quality conditions in your area. With the right system in place, you can ensure the safety and health of your family.
