Multipure Aquasource (Whole-House System)
The Aquasource provides point-of-entry filtration, treating all water entering your home—showers, baths, laundry, dishwashing, and drinking water.
NSF Certifications:
- NSF/ANSI 42: Aesthetic effects
- NSF/ANSI 53: Health effects
- NSF/ANSI 401: Emerging contaminants
How it works:
Installs at point-of-entry (garage or basement near water heater). Uses an array of multiple solid carbon block filters to reduce contaminants while maintaining household water pressure for simultaneous use across multiple fixtures.
Key Benefits:
- Filtered water at every tap, shower, and appliance
- No pressure loss during simultaneous use (multiple showers, laundry, dishwasher running)
- Reduces chlorine exposure during bathing (skin and respiratory)
- Protects appliances and plumbing from sediment and chemical buildup
Installation: Professional installation required. System integrates with existing plumbing at main water line entry.
Best for: Well water users, households wanting whole-home protection, those with skin sensitivity to chlorine, homes with high simultaneous water use
Pairing with Natural Action: Many customers install Aquasource for whole-home filtration and add an Aquaversa at the kitchen sink for enhanced drinking water quality, or pair with a Whole Home Revitalizer for combined filtration + structured water throughout the home.

Frequently Asked Questions
What does NSF certification mean, and why does it matter?
NSF International is an independent third-party testing organization that verifies water filtration product performance claims. 92% of filtration buyers prefer independently certified filters and are willing to pay 17% more for certified products.
Multipure systems are certified under multiple NSF/ANSI standards:
- NSF 42 (Aesthetic Effects): Reduces chlorine taste, odor, and particulates
- NSF 53 (Health Effects): Reduces contaminants with known health impacts (lead, mercury, asbestos, VOCs, cysts)
- NSF 401 (Emerging Contaminants): Reduces pharmaceuticals, BPA, PFOA/PFOS, pesticides, herbicides
- NSF P231 (Microbiological Purifier): Reduces bacteria (99.9999%), viruses (99.99%), and cysts (99.9%)—only the Aquaperform and Aqualuxe carry this certification
These certifications verify that Multipure's products reduce a wide range of contaminants while maintaining structural integrity and material safety.
Which contaminants do Multipure filters remove?
Multipure solid carbon block filters are certified to reduce 80+ contaminants depending on the model. Common contaminants include:
Heavy metals: Lead, mercury, arsenic V (Aquaperform only)
Disinfection byproducts: Chlorine, chloramine, trihalomethanes
Volatile organic compounds (VOCs): Benzene, toluene, xylene, MTBE
Pesticides & herbicides: Atrazine, lindane, metolachlor, DEET
Forever chemicals: PFOA, PFOS
Emerging contaminants: Pharmaceuticals (ibuprofen, naproxen), BPA, estrone
Microbiological: Bacteria, viruses, cysts (Giardia, Cryptosporidium)—Aquaperform P231 certification
Particulates: Asbestos, sediment, turbidity
For complete contaminant lists and performance data, view the NSF certification listings or request product-specific performance data sheets.
How do Multipure filters compare to pitcher filters or refrigerator filters?
Solid carbon block filters are the most effective consumer means for reducing a wide range of contaminants; certain systems have been certified to reduce upwards of 85 contaminants.
Multipure solid carbon block vs. pitcher filters:
- Contaminant reduction: Multipure systems reduce 80+ contaminants across 4 NSF standards; most pitcher filters reduce 5-15 contaminants (primarily chlorine, taste/odor)
- Flow rate: Multipure delivers 0.75-1 gallon/minute on demand; pitchers require filling and waiting
- Capacity: Multipure filters last 600-750 gallons (~12 months); pitcher filters last 40-80 gallons (~2 months)
- Cost per gallon: Multipure ~$0.12/gallon; pitcher filters ~$0.25-0.50/gallon
Multipure vs. refrigerator filters:
- Refrigerator filters typically reduce chlorine, taste, and odor but are not certified for health-effect contaminants like lead, arsenic, or PFOA/PFOS
- Multipure systems are NSF 53 and 401 certified for health-effect and emerging contaminants
- Refrigerator filters require frequent replacement (3-6 months); Multipure filters last 12 months
How do Multipure filters work with Natural Action structured water units?
Natural Action recommends a two-stage approach for optimal water quality:
- Filtration first (Multipure): Removes chemical and microbiological contaminants
- Structuring second (Natural Action unit): Revitalizes filtered water through vortex flow dynamics
Recommended pairings:
- Under-sink drinking water: Multipure Aquaversa → Natural Action Under-Sink Revitalizer
- Whole-home: Multipure Aquasource (point-of-entry filtration) → Natural Action Whole Home Revitalizer (main line structuring)
- Custom systems: Contact Natural Action for integrated filtration + structuring designs
The Aquaversa allows structured water to maintain the qualities supported by the Whole Home Revitalizer—something many filters do not do as effectively.
How often do I need to replace Multipure filters, and what do they cost?
Replacement schedule:
- Aquaperform: Every 600 gallons or 12 months, whichever comes first
- Aquaversa: Every 750 gallons or 12 months, whichever comes first
- Aquasource: Varies by household usage; typically 12-18 months
Annual filter cost: Approximately $90 for under-sink models (Aquaversa, Aquaperform)
Replacement is simple: unscrew the housing, remove the old cartridge, insert the new cartridge, and re-secure the housing. No tools required for most models.
Do Multipure filters remove beneficial minerals?
No. Multipure solid carbon block filters use mechanical filtration, adsorption, and catalysis to remove contaminants while leaving beneficial minerals like calcium and magnesium in the water. Unlike reverse osmosis systems that strip all dissolved solids, carbon block filtration is selective—removing harmful compounds while retaining mineral content that supports taste and health.
Can I install a Multipure system myself, or do I need a plumber?
Under-sink systems (Aquaversa, Aquaperform): Most homeowners can install these systems with basic tools. Installation involves:
- Drilling a hole for the dedicated faucet (if not using existing spray hose or soap dispenser hole)
- Connecting the system to the cold water line under the sink
- Connecting the outlet line to the dedicated faucet
Installation typically takes 30-60 minutes. Multipure provides detailed instructions, and video tutorials are available.
Whole-house systems (Aquasource): Professional installation is recommended. The system installs at the main water line entry point (garage or basement) and requires plumbing integration to maintain proper flow and pressure.
Are Multipure filters NSF-certified to remove PFAS (forever chemicals)?
Yes. The Aquaperform and Aquaversa use solid carbon block filtration to reduce PFOA and PFOS, two of the most common PFAS compounds, and are certified under NSF/ANSI 401 (Emerging Contaminants) and NSF/ANSI 53 (Health Effects) for these contaminants.
For households with known PFAS contamination, we recommend the Aquaperform, which has enhanced carbon block media for broader PFAS reduction.
What is the difference between NSF 53 and NSF P231 certification?
NSF 53 (Health Effects): Certifies that a filter reduces specific contaminants known to cause adverse health effects, such as lead, mercury, asbestos, VOCs, and cysts. This is the standard for most drinking water filters.
NSF P231 (Microbiological Purifier): A higher standard that certifies a system can purify microbiologically compromised water—reducing bacteria by 99.9999%, viruses by 99.99%, and cysts by 99.9%. This is among the highest levels of certified water protection, often sought by military bases, schools, restaurants, and food processing plants.
Only the Multipure Aquaperform (among under-sink models) carries NSF P231 certification, making it suitable for well water or areas with microbiological contamination concerns.
How do I know which Multipure system is right for me?
Choose Aquaperform if:
- You have well water or known arsenic contamination
- You need microbiological purification (bacteria, viruses, cysts)
- You want the highest level of NSF-certified protection (4 certifications including P231)
Choose Aquaversa if:
- You have municipal water and want broad-spectrum contaminant reduction
- You plan to pair with a Natural Action structured water unit
- You prioritize taste improvement, chlorine removal, and emerging contaminant reduction (PFOA/PFOS, pharmaceuticals)
Choose Aquasource if:
- You want whole-home filtration at every tap, shower, and appliance
- You have well water or high sediment/chlorine in municipal water
- You want to reduce chlorine exposure during bathing and protect appliances from buildup
