PUREPLUS 2-Stage Filter Overview
PUREPLUS 2-Stage Whole House Filter traps rust, sand, and silt for households requiring a 30,000 Gallon filtration capacity.
Using a Coconut Shell Carbon Block allows for the removal of 99%+ chlorine, bad taste, and odors while retaining healthy minerals in your home’s water supply. This dual-action approach ensures that the water feels and tastes cleaner without stripping away essential minerals.
The PUREPLUS 2-Stage Filter achieves this result by combining the carbon block with a 20-micron pre-filter for comprehensive whole-house protection. It is a 1″ NPT port system that includes a bracket and wrench, making it a complete kit for main line installation.
We evaluated 52 whole house water filtration options and selected this model for a full review because it is one of the most-rated products that passed screening, holding 59 buyer ratings.

The Short Answer on the PUREPLUS 2-Stage Filter
Best for: you need to filter sediment from a private well or high-sediment municipal source and require a dual-stage system for a household of up to four people.
The PUREPLUS 2-Stage Filter is a practical choice at the $144.99 price point.
- Pro: The coconut shell carbon block removes 99%+ chlorine and VOCs while retaining healthy minerals.
- Pro: Dual pressure gauges provide a visual readout of the system’s performance.
- Con: The 30,000-gallon capacity limits the service life to roughly 3 months for a large family, requiring more frequent media changes.
- Con: The 1″ NPT ports require your existing plumbing to match this specific standard for a proper connection.
Don’t buy this if: you require a filter with a service life exceeding 150,000 gallons, as this unit falls below that typical lifecycle capacity.
Price assessment: The $144.99 price is fair for a dual-stage system that includes both a 20-micron sediment pre-filter and a carbon block.
Green Writer score: 8.2/10 (data-driven – see “How we picked” above)

Before You Buy: A Whole House Water Filtration System Checklist
The first thing to check is the plumbing connection size to ensure the unit fits your existing pipes.
- ☐ Confirm the inlet and outlet ports are 1″ NPT — if your plumbing uses a different thread size, you will need to purchase adapters to avoid a leak.
- ☐ Measure a footprint of 16″L x 7.2″W x 15.2″H — insufficient clearance in your utility space will prevent the unit from being installed.
- ☐ Verify your water volume needs against the 30,000-gallon capacity — if your household exceeds this volume in under 3 months, you may experience media breakthrough, where exhausted media allows contaminants to pass through.
- ☐ Check that you have enough space for a 20-micron heavy sediment pre-filter — if the surface area is too small for your flow rate, a pressure drop will restrict water flow to your showers and appliances.
- ☐ Budget around $144.99 for the initial purchase — failing to account for the price of the PUREPLUS 2-Stage Filter may prevent you from completing the purchase.
You should not buy this product if you require a system that can provide clean water for a large household for a full year, as the 30,000-gallon capacity is lower than the 100,000 to 150,000 gallons required for that duration.
You can install the PUREPLUS 2-Stage Filter yourself in about 30 minutes because it is a countertop-style whole-house system. The process begins with positioning the unit in your workspace, then connecting the 1″ NPT ports to your water lines. You finish by tightening the included fittings and wrench to secure the connection.
To clear enough space for the unit, you need a dedicated area that can accommodate 16″L x 7.2″W x 15.2″H. This allows the 20-micron heavy sediment pre-filter (a filter that traps rust, sand, and silt) and the coconut shell carbon block to sit freely without obstructing your utility room.
What These Specifications Let You Do
How a 20-micron rating traps sediment from well water
The PUREPLUS 20 Micron 2-Stage Whole House Filter traps rust, sand, silt, and debris from well water or dirty sources using a 20-micron rating. This rating is sufficient for filtering out heavy sediment, as it captures particles significantly smaller than standard sand or silt grains. For a family of four, the 30,000-gallon capacity provides enough filtration for about 54 to 81 days of use, even under heavy sediment conditions.
The PUREPLUS 2-Stage Filter supports a maximum flow rate of 20 Gallons Per Minute while maintaining water pressure. Because the filtration capacity is 30,000 gallons, you can expect to replace the cartridges every 2 to 3 months if your well produces high sediment levels. This capacity is lower than the 150,000-gallon lifecycle of a standard 20-inch sediment/carbon cartridge, which marks the typical benchmark for long-term use in the category.
Coconut shell carbon block removes chlorine and odors from water
The PUREPLUS 2-Stage Filter removes 99%+ of chlorine, bad taste, odors, and organic chemicals using a coconut shell carbon block. This carbon block also retains healthy minerals while providing whole-house protection. If you need to treat water for a large household for a year, you would require 100,000 to 150,000 gallons of capacity, meaning this unit would require several replacements to meet that specific workload.
This system utilizes oxidation reduction potential, a filtration type used to treat water chemically and physically. The 30,000-gallon capacity allows you to treat water for a large family for about 2 to 3 months before the media requires replacement. You can rely on the coconut shell carbon to address the specific chemical profile of your water supply without removing the minerals you want to keep.
Dual pressure gauges monitor resistance in this A Whole House Water Filtration System
Dual pressure gauges on the PUREPLUS 2-Stage Filter allow you to monitor the pressure before and after the water passes through the filtration media. These gauges provide a visual indicator of how much resistance the filter is providing to your plumbing system. You can use these readings to identify when the filter is becoming clogged with sediment and requires a cartridge change.
The 1″ NPT ports provide the standard plumbing size required for most residential main line connections. By monitoring the pressure drop across the unit, you can ensure the 20-micron rating isn’t restricting flow to your showers and appliances. If the pressure drop becomes significant, it indicates the 30,000-gallon capacity has been reached or the sediment load has exceeded the current media’s limits.

| Provide clean water for a large household for a year | 100,000 to 150,000 Gallons for 12 months, 85% usable | About 2 to 3 months – short of the 12 months the job takes |
| Filter water for a family of four for one month | 10,000 to 15,000 Gallons for 30 days, 90% usable | About 54 to 81 days – enough for the whole 30 days even at the heavier end |

Final Verdict on the PUREPLUS 2-Stage Filter
You need a system that handles heavy sediment and organic chemicals from a private well before you upgrade your current filtration. The PUREPLUS 2-Stage Filter is a suitable choice at the $144.99 mark.
The 30,000-gallon filtration capacity allows you to filter water for a family of four for about 54 to 81 days, even under heavy usage. This capacity provides enough volume to sustain a household for roughly three months of consistent use.
The PUREPLUS 2-Stage Filter uses a coconut shell carbon block, which is a type of filter that removes 99%+ of chlorine, bad taste, and odors. It also features a 20-micron heavy sediment pre-filter to trap rust, sand, and silt from dirty water sources.
The 1″ NPT ports provide the standard plumbing size for most residential main line connections. Because the 30,000-gallon capacity is lower than the 150,000-gallon lifecycle of a standard 20-inch sediment/carbon cartridge, you should plan for more frequent media changes in high-sediment environments.
The PUREPLUS 2-Stage Filter includes dual pressure gauges to monitor performance. These gauges help you see if the 20-micron rating is maintaining water pressure or if the media requires attention.
The 30-minute DIY installation is designed for a countertop setup, though it is listed as a whole-house system. You should confirm your mounting space can accommodate the 16″L x 7.2″W x 15.2″H dimensions before ordering.
You should choose the PUREPLUS 2-Stage Filter if you need to treat well water with high sediment levels and want a system that removes 99%+ of organic chemicals. The $144.99 price point provides a dedicated two-stage solution for rural or private well setups.
The 4.3 rating from 59 buyer ratings indicates a consistent user experience for this specific filtration configuration. This rating provides a reliable signal of the system’s performance in real-world residential settings.
Skip it if: You need a filter to last a full year for a large household, as the 30,000-gallon capacity will be exhausted in roughly 3 months.
