Top 4 Best 3-Stage Reverse Osmosis Systems 🥇(December 2024)
Last Updated: 21 December 2024
In this article, we’re going to be talking about the best 3-stage reverse osmosis water systems that are available on the market.
Reverse osmosis systems are used to remove poisonous substances, contaminants, bacteria, and much more from our water supply, so that the drinking water is clean and able to be consumed in a safe way.
3-stage RO units have three individual filtering stages, which are used in combination to remove these substances, contaminants, and bacteria.
If you’re worried about the quality of drinking water in your home or commercial environment, experts are also giving even more reasons to be concerned.
Why? Well, between 1982 and 2015, millions of Americans got their drinking water from a source that was in violation of the Safe Drinking Act.
And even now, researchers at the nonprofit Environmental Working Group and Northeastern University found out last year that at least 43 US states have sites where toxic fluorinated compounds known as PFAs contaminate drinking water.
That they make your tap water safe to drink isn’t the only reason why you might want to invest in a high-quality tanked or tankless RO system.
These water filters also improve the taste of your water, eliminate up to 99% of all contaminants, neutralize any odors, and improve its quality.

The WGB32B by Spring is a whole house filtration system suitable for general usage, designed for cleaning up water supplies to a home or business on municipal (city) water.
Unlike “point of use” systems (like reverse osmosis systems) that are installed to supply water to a specific faucet, the WGB32B filters your water from the source. This means water from every output in your home or business will have passed through the three filtration stages of the WGB32B.
Used as the first stage of defense on the system, the stage 1 housing holds a 5-micron high-capacity polypropylene sediment filter. This filter removes dirt and other various larger sized particles from the water that can clog the following filters.
The second and third stages of the WGB32B house 5-micron CTO coconut shell carbon block filters. Block carbon is more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters, and are therefore more effective in removing their targeted contaminants.
The carbon block filters knock out bad tastes and odors, combine to remove over 90% of chlorine from the water, and are highly effective on organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals.
If you are on well water or have unusual contaminants in your municipal water supply, you may want to consider the WGB32BM over the WGB32B
Pros
- Great customer reviews
- Extremely affordable
- High GPM
- Removes common contaminants
- 5-micron filter
- Easy to install
- Suitable for general usage
Cons
- Not for well water (use WGB32BM instead)
iSpring WGB32B-PB 3-Stage Water Filtration System – Whole House – Lead – $$
Technical Specs
- Filter Stages: 3-Stage
- Gallons per minute (GPM): 15
- Water pressure: 25-80 psi
General Specs

The WGB32B-PB whole house filtration system is an ideal “point of entry” filtration system for cleaning up well water.
Unlike “point of use” systems (like reverse osmosis systems) that are installed to supply water to a specific faucet, the WGB32B-PB filters your water from the source. This means water from every output in your home will have passed through the three filtration stages of the WGB32B-PB.
What exactly do these three stages of filtration offer?
Used as the first stage of defense on the system, stage 1 housing holds a 5-micron high-capacity polypropylene sediment filter. This filter removes dirt and other various larger-sized particles from the water that can clog the following filters.
The second stage of the WGB32B-PB houses a 5-micron CTO coconut shell carbon block filter. Block carbon is more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters and are therefore more effective in removing their targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes over 90% of chlorine from the water, and is highly effective on organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals.
The third stage of the WGB32B-PB houses an iron and lead reducing filter. The FCRC25B iron and lead reducing filter are only included with the WGB32B-PB model.
Pros
- Fantastic customer reviews
- Extremely affordable
- High GPM
- Suitable for cleaning well water
- Removes common contaminants (But more particularly lead)
- 5-micron filter
- Easy to install
Cons
- A little more expensive than the WGB32B unit

The third stage of the WGB32BM has an iron and manganese reducing filter – also great for the plethora of heavy metals found in well water sources. The FM25B iron and manganese reducing filter is only included with the WGB32BM, as it is not needed for most municipal water supplies that the WGB32B targets.
If you are on municipal (city) water or a generally clean water supply, you may want to consider the WGB32B over the WGB32BM. For removing the common contaminants and heavy metals found in the majority of well water supplies however, the WGB32BM fits the bill.
Pros

- Extremely affordable
- High GPM

- Removes common contaminants (But more particularly iron & manganese)
- 5-micron filter
