Frequently Asked Questions

How do I know which system is right for my home?

It comes down to your water source (city or well), the number of bathrooms in your house, and what you’re trying to address. City dwellers might be okay with just a simple filtration system like the 20″ Big Blue, while well water often needs something more robust, such as the Aquasana Well System. For hard water, the Whirlpool Hybrid or Aquasure Harmony are solid choices. The APEC bundle is a good option if you want both filtration and softening.

What does “grain capacity” mean with water softeners?

Think of “grain capacity” as how much hardness a softener can remove before it needs to recharge. A higher number means it can go longer between recharges. For example, the Aquasure Harmony with 48K grain capacity is great for larger homes or those with very hard water.

What’s the difference between salt-based and salt-free systems?

Salt-based softeners like the Whirlpool Hybrid actually remove the minerals that cause hard water through a process. Salt-free systems, like the Aquasana Well System, condition the water so the minerals don’t stick to pipes and appliances, but they don’t actually remove them. Folks often choose salt-free when they want to avoid the sodium added to the water by traditional softeners.

Do I need a professional to install these systems?

Some of these are DIY-friendly, especially the simpler filtration systems like the 20″ Big Blue. However, for more complex systems, such as the APEC bundle or the Aquasana Well System (especially with the UV purifier), you might want to call in a pro. This is especially the case if you’re not comfy with plumbing or electrical work.

How often do I need to replace or maintain these systems?

It varies. The 20″ Big Blue filters will need changing every 6-12 months. Salt-based softeners require salt refills every so often (the Whirlpool Hybrid has a low-salt alert to help with that). The Aquasana Well System has a long-lasting 500K gallon capacity, which could mean years between replacements. Regular checks can also ensure everything’s running smoothly.
