1. SpringWell WS1 Whole House Well Water Filter System: 9.4/10

  • The best micron water filter for well water
  • Price: $2,204.09

The SpringWell Whole House Well Water Filter System effectively removes a wide range of contaminants commonly found in well water, including sediment, volatile organic compounds (VOCs), pesticides, herbicides, and various other impurities.

Pros

The Springwell whole house filter system uses a spin-down sediment filter, a 1-micron mesh screen, and an air injection oxidation system to effectively trap sediment, such as sand, silt, and rust, that can cause sedimentation and potentially damage plumbing fixtures and appliances.

With a 1-micron rating, the mesh screen is effective at trapping sediment particles that are 1 micrometer or larger in size. This includes finer sand, silt, and other microscopic debris that may be present in well water. The air injection oxidation system removes 8 PPM (parts per million) of hydrogen sulfide, up to 7 PPM of iron, and 1 PPM of manganese.

One very convenient feature is the automatic backwashing function, which reverses the flow of water within the filtration system and flushes the captured contaminants and debris out of the system. This prevents clogging and prolongs the lifespan of the filtration media. It also ensures consistent performance by removing accumulated contaminants and debris.

Even better, you can initiate a manual regeneration system using your phone or tablet. This system is fitted with a Bluetooth head that allows you to not only manually configure the backwash feature but also monitor water usage data.

Cons

Just keep in mind that this is an expensive unit, and the initial cost may be higher compared to simpler water filters. Of course, it comes with an amazing lifetime warranty on the tank and valves, and a six-month money back guarantee. Also, the greensand filter has a lifespan of 18–25 years. So it’s pricey, but SpringWell stands by its design.

While installation can be relatively straightforward for those familiar with plumbing, you may need professional installation. Additionally, the system includes a large tank, so you’ll need sufficient space available to accommodate it.

The effectiveness of the SpringWell system depends on the quality of your well water. While it’s designed to handle common well water contaminants, contaminants vary from location to location. Fortunately, available upgrades, including a salt-based water softener and a reverse osmosis water filter, can help filter excess contaminants.

Overall

Despite the upfront cost, it’s important to consider the long-term benefits and savings from reduced maintenance and potential health-related costs. If you’re in the market for a comprehensive, convenient, and highly effective micron filter for your well water, buy the SpringWell WS1 Whole House Well Water Filter and stop worrying about your water.

2. Aquasana Rhino Whole House Water Filter with UV Filter: 8.8/10

  • Best for microbe removal
  • Price: $1,698

The Aquasana Rhino Well Water Filter with UV Filter System combines multiple filtration stages, including sediment filtration, activated carbon filtration, and UV disinfection, to provide thorough and effective purification of your well water.

Pros

The 5-micron pre-filter in the Aquasana Rhino effectively captures sand, silt, rust, and other particulate matter present in well water. These particles can cause cloudiness, discoloration, and potential clogging issues in plumbing fixtures and appliances. Larger suspended solids, including dirt, debris, and organic matter, can also be trapped by the pre-filter. 

The 0.35-micron post-filter effectively captures smaller sediment and particles that may have passed through the previous filtration stages. This low micron rating also implies that the post-filter is capable of removing certain bacteria, larger viruses, and harmful microorganisms that can cause waterborne illnesses.

The UV filter stage utilizes ultraviolet light to disinfect the water by inactivating bacteria, viruses, and other harmful microorganisms. This stage provides an extra layer of protection against waterborne pathogens, ensuring that the water is safe for consumption.

Cons

While the Aquasana Rhino filter for well water is effective at removing sediment, chemicals, bacteria, and viruses, it may not be as efficient at removing certain other contaminants, such as heavy metals, fluoride, or dissolved solids. Because of the upfront cost, as well as installation, plumbing modifications, and maintenance, its filtration may not be sufficient.

Additionally, the filtration process, particularly the UV disinfection stage, can slightly reduce your water’s flow rate. While the impact is usually minimal, it’s important to consider the potential reduction in water pressure and adjust accordingly.

Overall 

Despite its shortcomings, the Aquasana Rhino whole-house sediment filter is a decent and cheaper alternative to the SpringWell filtration system. Check it out here

The Best Micron Filter System for Well Water: Review Methodology

In this section, I explain in detail the process I went through to review these seven water filters for well water.

Step 1: A big list of all available products

Because I was starting from scratch, I needed to know the major players in the water filtration sector. This included developing a comprehensive list of reputable companies in the sector. 

I spent hours searching Amazon, Lowes, Home Depot, and Costco for the best-selling brands of well water filters with different micron ratings. I also spoke with a few water treatment dealers to broaden the scope of my investigation. I ended up with a list of 25 distinct models.
