Cure Problem Water With A Trusted Product
Arsenic is a naturally occurring contaminant you can’t see, smell, or taste which is exactly what makes it so concerning. It’s found in groundwater across California and can affect both well and municipal supplies. A whole house arsenic filter reduces this potentially harmful contaminant at the source, giving you cleaner, safer water. Likewise, you’re backed by the best water treatment service in the industry.

Why Price Tags Are Deceptive
Unless you were an expert installer, you wouldn’t buy a water heater directly off Amazon. However, big box retailers, both in-store and online, take this transactional approach to homeowners for whole house arsenic filtration. They offer you low price tags for incentive. But what they don’t tell you about are the installation hassle, the third-party customer service on both ends, and how you’re left to your own devices to maintain your system – don’t forget, your home is unique. There is no one-size-fits-all solution. If you truly want to save throughout the life of your system, go with the expert!

Whole House Filter FAQ
We Have Answers!
How Does An Arsenic Filter Remove Arsenic From Water?
The Aquasential™ Arsenic Reduction filter uses high-absorption Cull-AsX53 media that adsorbs arsenic as water passes through. It’s a chemical-free process that requires no regeneration chemicals, salts, or additives. The system simply reduces arsenic at the source and alerts you when the media needs replacement.
Can I Tell If I Have Arsenic Without A Test?
No. Arsenic is colorless, odorless, and tasteless, so there are no warning signs in your water. The only way to know your levels is a water test. A free Culligan in-home water test will measure your exact arsenic levels and confirm whether a filter is needed.
Is The Culligan Arsenic Filter Certified?
Yes. It’s the only certified whole house arsenic water filter on the market, independently certified by IAPMO against NSF/ANSI Standard 53 for the reduction of up to 100 ppb of total arsenic, plus NSF/ANSI 372 and CSA B483.1.
Does It Remove Both Types Of Arsenic?
Yes. The Cull-AsX53 media is designed to reduce both Type III (trivalent) and Type V (pentavalent) arsenic — an important advantage, since many filters only address one form.
How Is The System Installed And Maintained?
Your local Culligan water experts handle everything from the free in-home water test and installation to ongoing maintenance like filter changes and system sanitation. Your system can be installed anywhere with access to main water piping, a drain, and an electrical outlet, and can be monitored proactively through the Culligan Connect™ App.
Do I Need This If I’m On Municipal Water?
Possibly. Even treated municipal water can contain arsenic at varying levels, and private wells aren’t regulated at all. A whole house arsenic filter provides consistent, added protection at every tap. Your water test will tell you what’s right for your home.
What Sizes And Models Are Available?
The Aquasential™ Smart High Efficiency Arsenic Reduction filter comes in 12″, 14″, and 16″ sizes, in both indoor and outdoor models, operating at 20–120 psi. Your Culligan expert will size and place the system to fit your home.
What Warranty Comes With The System?
Culligan products are reliable and long-lasting with industry-leading warranties: a lifetime warranty on the Quadra-Hull® tank; a ten-year warranty on the GBX circuit board and control valve body; a five-year warranty on the Soft-Minder® meter; and a one-year warranty on the entire system.
How Much Does A Whole House Water Filter Cost Compared To A Reverse Osmosis Filter?
Whole house water filters are typically more expensive than reverse osmosis systems for a couple of reasons. A RO system only filters water at one tap, while a whole home filter operates as a water system throughout your home. Likewise, custom options to filter major issues such as iron and sulfur are not applicable to a reverse osmosis system. Think of an RO system taking care of your drinking water at one tap, while a whole house filter provides customizable solutions for all water problems — scale, hardness, laundry — throughout your home.
Do Whole House Water Filters Soften Water?
Whole house systems are designed to reduce sediment, chlorine and other contaminants, leaving you with cleaner, safer, fresher-tasting water. Based on the makeup of your water, Culligan may recommend a combination of whole-house filtration and water softening. Minerals such as calcium and magnesium can decrease the effectiveness of your whole house water filter, so if there is a need for a whole house filter in an area with a high level of hardness, this would be the solution suggested by your Culligan expert.
Do Whole House Water Filters Reduce Water Pressure
An undersized or poorly-installed whole house water filter will reduce your water pressure throughout your home, which can range from a minor annoyance to a major flow issue in your sinks and showers. You can prevent this issue by avoiding retail and third-party plumbers, who do not have experience installing whole house water filters as their primary job. Culligan also provides your product with a warranty, as well as maintenance options so if there is an issue, it can be fixed immediately.
