Specifications side by side

Aquasana Whole House Filters Compared

You will find two distinct paths here. The Rhino Well + Pro Kit suits well water homes needing UV protection. It is a large system measuring 57 inches tall and weighing 116 pounds. This unit provides robust pathogen protection for households with moderate hardness. You get high capacity filtration designed specifically for well water sources.

The Max Flow UV system targets high-flow homes needing sterilization. It is compact, weighing only 12 pounds, and offers 16 GPM. This model focuses on microbial protection and chlorine reduction. It is ideal if you need chemical-free disinfection certified by NSF/ANSI Standard 55. Choose the larger kit for well safety or the compact unit for high-volume chlorinated water.

Where Aquasana fits

Aquasana’s current lineup targets two specific needs. You can choose a compact UV unit for high-flow homes or a large, heavy kit for well water. The range spans from a small 12-pound cylinder to a massive 116-pound system with conditioner. Both models include UV sterilization. You will not find standard carbon-only filters here. There are no models designed solely for chlorine reduction without UV treatment. If you need basic sediment filtration without pathogen protection, this brand’s whole house options may not suit you. The spread is narrow, focusing on disinfection capacity rather than general filtration variety.

How to choose the right Aquasana system

1. Match the system to your water source

   Your water source dictates the necessary filtration path. If you rely on well water, you likely face higher microbial risks and sediment loads. The Rhino Well + Pro Kit is designed specifically for this use case. It includes a conditioner to handle moderate hardness. If you are on city water, you may not need the full well kit. Check the product attributes to confirm the intended use. Selecting a system built for your specific source ensures the media works effectively without premature clogging or inadequate protection.

2. Check UV sterilization certification

   UV filtration provides chemical-free disinfection by neutralizing microbes. However, not all UV units are created equal. Look for systems certified to NSF/ANSI Standard 55 Class A. This certification ensures the unit delivers a sufficient UV dose to kill bacteria and viruses. The Max Flow UV system carries this specific certification. This standard is critical for whole house applications where you need guaranteed pathogen reduction. Verify the certification level in the specs to ensure your family receives true microbial protection.

3. Evaluate flow rate for household size

   Flow rate determines how many fixtures can run simultaneously. The Max Flow UV system supports up to 16 gallons per minute. This high volume suits larger households with multiple bathrooms. If you have a smaller home, a lower flow rate might suffice. Check the gallons per minute rating in the product data. A system that cannot keep up with your demand will cause pressure drops. Match the flow specification to your peak usage times to maintain consistent water pressure throughout the house.

4. Assess physical footprint and weight

   Whole house systems require significant space in your utility area. The Rhino Well + Pro Kit is substantial, weighing 116 pounds and measuring 69 inches long. It needs a sturdy floor and ample clearance. In contrast, the Max Flow UV unit is compact, weighing only 12 pounds. It fits into tighter spaces. Measure your installation area before ordering. Ensure your floor can support the weight of the larger kit. Proper spatial planning prevents installation delays and ensures safe, secure mounting of the unit.

5. Consider additional filtration stages

   Some systems combine multiple filtration methods for comprehensive treatment. The Rhino Well + Pro Kit includes a conditioner alongside its main filters. This adds a stage to address water hardness and improve taste. The Max Flow UV system focuses on chlorine reduction and UV sterilization. Decide if you need extra conditioning stages. More stages mean higher capacity but also larger physical size. Review the features list to see what is included. Choose the combination that addresses all your specific water quality concerns.
