Built from stainless steel and food-grade plastics, the system guarantees a long lifespan. The filters themselves have a 100,000-gallon capacity, and when it is time to change them it’s an easy process.
And the 0.25 gallon per second flow rate, translating to around 15GPM, ensures the system won’t choke with high use. It’s perfect for families looking to purify their well water.
3. Aquasana Whole House Well Water Filter System – Best For Low Maintenance and a Long Lifespan
Aquasana’s impressive whole house well filter system utilizes activated carbon and a KDF membrane and then combines this switch UV purification and descaling for ultimately pure water.
- Softens water thanks to the descaler

However, with no descaler, you may need to bolt on a water softener to your system to extend the lifespan of the filter system as a whole.
iSpring has designed a more compact unit with no compromise on filtering and it comes with everything you’ll need for a seamless DIY installation.
5. 3M Aqua-Pure AP903 – Best For Great Tasting Drinking Water
The 3M Aqua-Pure isn’t designed to remove every contaminant under the sun, but it is highly targeted at aesthetic impurities and great for anyone on a budget.
- Great value
- Reduces sediment
- Great for taste
- NSF certified to reduce aesthetic impurities
- 100,000-gallon capacity
- Limited filtering – bacteria, viruses, and other contaminants aren’t targeted
- Additional components required for installation
The filter is NSF 42 certified, meaning it removes impurities that impact taste and quality of drinking water. That includes sediment and chlorine. But viruses, metals, and bacteria won’t be removed. Make sure you know your water quality inside out before you buy.
It has an impressive capacity of 100,000 gallons making it great for families, and a flow rate of up to 15 GPM ensures you’ll never run dry.
It’s designed for DIY installation, but be prepared to pop to the hardware store as there are a range of components and fittings not included, such as plumbers tape, 1” connections, and 2” ball valves.
Nevertheless, it offers great value if you’re looking for crisp and flavorsome drinking water and you’re not worried about a whole lot else!
6. Culligan WH-HD200-C – Best For Targeting Rust And Sediment
Culligan’s combo filtration system and cartridge is a budget option that targets a few pesky contaminants in your water supply.
- Great budget option
- Targets sediment and rust
- Reduces odor and improves water taste
- Easy installation
- Bypass shut-off valve
- 3 GPM flow rate is restrictive
- A limited range of contaminants are filtered
The sediment cartridge is designed to block particles wider than 25 microns from entering your home water supply – it excels at removing rust, sediment, grit, and sand, and can reduce chlorine too.
The upshot is great-tasting drinking water without the sediment. However, it isn’t targeted at a range of chemicals and metals commonly found in well water – I’d recommend testing your water before committing to a limited filter like this one.
The filter cartridge has a 10,000-gallon capacity – so you can expect to change it every three months for average use, and more frequently if your water contains heavy sediment.
And the flow rate of just 3 GPM will occasionally limit you if you’re a busy household with high water usage.
But this is a great value sediment filtering option, and as it comes with everything you need for installation you’ll have an easy job getting filtered water flowing.
7. Aquaboon 20″ x 4.5″ – Best For Choice Of Replacement Filters
Aquaboon’s one-size-fits-all whole house well water filter system is quick and easy to install and, thanks to a standardized filter slot, gives you the widest choice when it comes to filter cartridges.
- 100,000-gallon capacity
- Targets rust and sediment
- Compatible with a wide range of off-brand filters
- Easy installation without specialist tools
- Limited filtering
- Additional plumbers tape required for installation
It’s a one-stage filter, meaning you miss out on pre- and post-filtering. The absence of KDF and activated carbon means that chemicals, viruses, and heavy metals aren’t targeted. But it’s a great option when it comes to rust and sediment.
Built from premium materials including a high-flow polypropylene (HFPP) cap, this is going to be a long-lasting and durable whole house well water filter system. The double-O ring lock reduces the risk of leaks to near zero.
The easy-install design doesn’t require any specialist tools and replacing filters is simple, minimizing the maintenance needed on the unit. In fact, Aquaboo has simplified almost everything to create an exceptionally easy-to-use product.

Home Master’s whole house well water filter features three stages for exceptional filtering capacity.
- Immense 15 GPM flow rate
- Sediment filtration down to 1 micron
- Targets metals and chemicals
- Reduces odor and improves water taste
- Premium price tag
- Will be damaged by chlorinated water
The activated carbon layer is effective at removing pesticides, herbicides, and chemicals, whilst the four-depth sediment filter can eliminate particles down to a microscopic 1 micron.
It’s also capable of reducing iron content to 3ppm – particularly crucial for well water. The output is a clean and great-tasting drinking supply.
Thanks to up-sized filters, it also offers a premium flow rate of up to 15 gallons per minute. It’s great for busy households with high water usage – you’ll never see the flow fall to a trickle with this.
And in the box is everything you need for installation, including bolts, brackets, and other components. This is a whole house well water system for comprehensive filtering, but it comes with a premium price tag.
9. EcoPure EPWO4 – Best Cheapest Option

The housing unit is built for a single filter, so this is 1-stage filtering. That means sediment and rust (down to 1 micron) can be removed and chlorine-removal is an additional option with the right filter.
But don’t be fooled by the price – this is just the housing unit and filters are sold separately. Nonetheless, it’s great value for anyone stepping into the whole house well water filter market.
Filters aside, everything you need for seamless self-installation is included. The durable BPA-free plastic components are designed for long life.
Ultimately, what will appeal to most is the price. Filtered water without splashing out.
Before You Buy: The Buying Guide For Whole House Well Water Systems
Need to know how to size a water filter system for your needs? Or what the essential features of whole house water filter systems are? Let’s take a deep dive into the world of whole house water filters for well water.
Targeted Contaminants
Finding a water filter that’s suited to your particular supply is essential. Whether you’re worried about lead and iron, pesticides or minerals in the form of TDS (total dissolved solids) should guide your purchase.
For a full-spectrum, multi-stage filtering is a great option. Pre- and post-filtering can remove chlorine, metals, and other chemicals and even offer remineralization to give you the best flavor in your drinking water.
Sediment Targeting
One of the main concerns with well water is sediment, rather than chemicals or pesticides. Sediment targeting is expressed in microns, and the smaller the number, the less detritus will make it through the filter.
Budget water filter systems will start filtering around 25 microns, whilst premium models can remove contaminants down to a minuscule 1 micron through multi-layered sediment filtering.
Filter Capacity and Lifespan
Whilst a well-built whole house water filter for well water will be made from durable materials and have a long lifespan, filters themselves are consumable products.
Filter capacity tends to be in the tens of thousands of gallons, but can stretch to 100,000 gallons in premium models, giving you and your family near-limitless filtered well water.
Filter lifespans are the manufacturer’s recommended time before a replacement is required. The quality of your water, including sediment and chlorine, will shorten the lifespan of your filter, and if you don’t replace the filter regularly, your water quality will be compromised.
3 to 6 months is a standard lifespan and the cost of replacement filters should be factored into your budget.
Flow Rate
Whether it’s the comfort of a warm power shower or just the time it takes at the sink to fill your water bottle, flow rate matters in your everyday life.
And a smaller flow rate might mean your family can’t use multiple showers or do the washing up whilst running a bath.
Small filters tend to have limited flow rates, down to about 3 GPM – just enough to run the shower, whilst premium whole house well water filters will stretch to 15 GPM, enough for the whole family.
Certification
In the world of water filters, NSF (National Science Foundation) certification is the main standard. However, this expensive certification is eschewed by some big-name brands, which use alternative independent lab testing.
For complete peace of mind, NSF certification is a must. But NSF also offers different levels of certification for different products, and a certificate doesn’t mean every contaminant is removed.
For example, NSF 42 certification ensures that aesthetic contaminants such as chlorine are removed, so you can be sure the filtered output will taste great – but it doesn’t tell you anything about contaminants that put your health at risk.
Water Softening
For true water softening, an additional reverse osmosis system will be required – but some whole house water filters for well water offer an additional descaling treatment to prevent the minerals in hard water from bonding with your pipes and appliances.
The presence of a descaler in premium models can actually save you money – the filters should last longer and maintenance will be lower than on other models.
Installation and Maintenance
Most whole house well water filter systems are designed for self-installation. But if you’re the type of person who tears their hair out over IKEA furniture, that might not help…
If you’re planning to opt for self-installation, make sure that all the necessary components are included as sometimes simple things like wrenches and plumbers tape are left out.
Most systems are very low maintenance once installed – replacing filters regularly is an important job.
Price
Lastly, price is always a factor. Whole house filter systems for well water can range from under $100 for simple, sediment removal filters to upwards of $1000 for powerful flow rates and premium capacity, and the widest range of contaminants filtered.
Final Thoughts
Anyone drawing their own water from a well will be used to a wide range of contaminants.
From rust discoloring your water to the chemical tang of chlorine, the water nature provides isn’t always clean.
And whilst taste and color might put you off your water, there are plenty of microscopic contaminants you can’t see. Bacteria can make your whole family sick, whilst heavy metals can slowly undermine your health.
For peace of mind with well water, you need a whole house filter for well water. And as we’ve seen, they don’t have to break the bank.
No matter which contaminants you need to target, or the size of your family's water needs, there’s a whole house water filter for your well water.
