#8. Home Master HMF2SMGCC 2-Stage System – Best for Tap Water

Features
- High-grade sediment filter for superior filtration
- Granular activated carbon to reduce chlorine, taste and odor
- KDF85 media to remove heavy metals

#9. 3M Aqua-Pure Whole House Water Filtration System

Like Aquasana’s EQ-1000, 3M’s Aqua-Pure AP904 also features a scale inhibition system that protects pipes and appliances.

- Reduces sediment, chlorine taste and odor, rust, dirt and other contaminants from your home’s water supply.
- Easy to install and includes a bypass valve for easy maintenance without having to shut off the water supply.
- Compatible with most existing plumbing systems.

Pros
- Its capacity is 100,000-gallons — a tenth of the EQ-1000 — and it doesn’t remove heavy metal or chemical contaminants
- If you don’t need that capability, it’s among the most economical filters on the market.
- This filter is great for a family of four and should last you about a year before needing to replace the filter.
- If your sediment levels are very high, it may need to be changed sooner.
- Do-it-yourself installation is a cinch and won’t compromise the warranty.
- Maintenance is as simple as an annual cartridge change.
Cons
- Not suitable for areas with hard water.
- May not remove all contaminants from the water.

Simplicity defines this filter. Both installation and cartridge changes are a snap. Water flow is generous and with one annual filter change, you can set it and forget it. It works with city water and protects your plumbing, but it’s mostly just a high-quality filter with softening capability.
It doesn’t remove heavy metals, chemicals, and it won’t make water potable, but if you don’t need that, why pay for it? Sometimes, simple is best.

Pros
- It has a similar 100,000-gallon total capacity and an even higher 15 GPM flow rate.
- It doesn’t remove lead, so if that’s your goal, you’ll need the WGB22B-PB version of this system, but if it’s not an issue.
- This unit will meet your needs for about 30-percent less than the Home Master. It’s a top value.
- It’s designed to be DIY-friendly but basic plumbing skills help.
- We really like that both replacement filters can be replaced at the same time — about once a year.
Cons
- Doesn’t reduce lead
- Not ideal for heavily chlorinated water
Our take
This system doesn’t remove lead. That’s a significant drawback if you want a water filter for peace of mind but don’t know what’s in your water. If you’re confident your water is lead-free, the WGB22B is a superb value. Your water will taste great, and it’s an
#11. Express 3-Stage Home Water Filtration System

- Compact design that fits easily in small spaces
- Affordable price point compared to similar systems
Cons
- Doesn’t remove heavy metals including lead.
- It’s on the pricey for filter replacements.
Our take
Express is a newcomer in the whole house water filter market, but this product is particularly well-built. It’s a few dollars more than it’s competitors, but it feels solid. You’ll want to be sure your water is lead-free before using this system, especially if you have kids, but it does what it says it’ll do, and it does it well.
The gauges help guide cartridge changes, and the system comes with lifetime technical support. I recommend it for nervous first-time filter buyers.

Buyer’s Guide: To Whole House Water Purification Systems
Investing in a whole house water filter doesn’t have to break the bank. You can evaluate your risks and find the best filtration system for your family without sacrificing other expenses.
Peace of mind against the unknown is important, but not all water supplies are prone to the same type of contamination. Make sure you get what you need without overspending.
Let’s look at the most important things to consider when making a purchase decisions.
In this guide, you’ll learn:
- How we chose these systems
- Key considerations
- Choosing the right system for your home
- How to test your water
- System size and footprint
- Frequently asked questions
How We Chose
We understand that it can be an overwhelming process if you’re new to whole home water filtration systems. So we wanted to set your mind at ease and share our selection process, and expertise, in what we feel are top considerations to make before any purchase.
In our selection process, we look at 7 key factors: certifications, contaminant removal, flow-rate, ease of use, maintenance requirements, warranties, and long-term ownership costs. We also take it a step further by speaking with the manufacturers of these brands for information we feel wasn’t covered well enough.
Before any system makes it on our list, we need to dig into online reviews and user feedback. In doing so, this process sometimes would reveal problems for a variety of reasons that our personal testing or research didn’t uncover.
Key Considerations

- Contaminant removal: Pay close attention to the systems ability to remove contaminants from water, including the type of filter media, micron size, and the efficiency and rate of contaminant removal.
- Flow-rate: This is especially important to those who already have low water pressure, pay close attention to max flow rates as these differ wildly between systems — anything above 7GPM (gallons per minute) is good.
- Ease of use: most manufacturers have helpful tutorials showing you how to install the system, should you opt to go the DIY route. Having said that, the systems we have listed above are overall DIY if need be.
- Maintenance requirements: Keep in mind, some systems may require a post and pre-filter that will need to be changed in 6-12 month intervals and should be taken into consideration.
- Certifications: Be sure to look for NSF/ANSI standards logo as that means the system does exactly what the manufacturer describes it should do — it’s an added level of quality assurance and peace of mind.
- Warranties: Pay close attention to the manufacturer warranties to have a clear understanding of what they cover and length of protection.
- Long-term ownership costs: Estimate long-term costs associated with owning this model, including replacement parts or maintenance services fees, so you can make an informed choice about purchasing it.
Contaminant Reduction Capability

City and well water can both contain contaminants like lead from aging pipes, chemicals, pharmaceutical residue, and microbes. Fluoride and chloride are added to municipal supplies but can be harmful. Hard water with excessive minerals will damage pipes and appliances. To select the right whole house filter system, you need to know what’s in your water now and evaluate potential future risks.
The best way to select a whole water house filter system is to know exactly what’s in your water and the best possible water treatment plan to resolve those issues. Test kits are available at hardware stores that allow you to send a sample to an independent lab for accurate results. For city water, contact your water treatment authority for more information.
See our top recommended water test kits.
System Type and Footprint
Whole house water filters are just as effective as point-of-use systems, but they provide larger capacity and require installation near the water entry point.
Make sure to measure the area beforehand and compare filter dimensions before purchasing.
Capacity
Brand | Capacity | Flow Rate |
---|---|---|
Springwell | 1,000,000 Gallons | Up-to 20 GPM |
Aquasanna EQ | 1,000,000 Gallons | 7 GPM |
Pentair P600 | 600,000 Gallons | 10 GPM |
Ispring WGB32B | 100,000 gallons | 7 GPM |
3M Aqua-Pure | 100,000 gallons | 10 GPM |
Filter capacity determines how many gallons a filter can process before needing to be changed. Always check the system’s total filter capacity – some have multiple filters with different change intervals. The higher the capacity, the less maintenance is needed for your whole house water filter.
Flow Rate
Fixtures & Appliances | Flow-rate (GPM) |
---|---|
Dishwasher | 1-3 GPM |
Washing Machine | 3-5 GPM |
Shower | 2-5 GPM |
Toilet | 2-3 GPM |
Faucet | 2-4 GPM |
A higher flow rate means a filter can process water faster. The average combined water-using activities (like flushing a toilet and showering) use 6 GPM, making that the minimum required for such tasks.
However, the more contaminants a filter removes, the lower its flow rate will be e.g. Aquasana EQ-1000 Whole House Filter System offers comprehensive filtration with a 7 GPM flow rate (lowest on our list), while Home Master’s HMF2SMGCC 2-Stage System has 15 GPM.
How to Calculate Your Water Flow Rate
You might not be aware of this important detail. However, it’s very important to know what your “effective flow-rate is” so that you can purchase the right size whole home filtration system for your needs so that you don’t buy an under-performing system.
1. Make sure all water faucets indoors is closed off and not running.
2. Grab a 5 gallon bucket and locate your water spigot.
3. Begin filling up your 5 gallon bucket and set a timer on how many seconds it takes to fill up.
4. For example: 5 GPM would be roughly 60 seconds to fill up a 5 gallon bucket. See our chart below.
Seconds To Fill 5 Gallon Bucket | Water Flow Rate | Seconds To Fill 5 Gallon Bucket | Water Flow Rate |
---|---|---|---|
76-100 | 3 GPM | 61-75 | 4 GPM |
51-60 | 5 GPM | 43-50 | 6 GPM |
38-42 | 7 GPM | 34-37 | 8 GPM |
31-33 | 9 GPM | 28-30 | 10 GPM |
26-27 | 11 GPM | 24-25 | 12 GPM |
22-23 | 13 GPM | 21 | 14 GPM |
20 | 15 GPM | 19 | 16 GPM |
18 | 17 GPM | 17 | 18 GPM |
16 | 19 GPM | 15 | 20 GPM |
14 | 21 GPM | 13 | 22 GPM |
12 | 23 GPM | 11 | 24 GPM |
10 | 25 GPM |
Micron Rating
When selecting the right filter for your home, it’s important to consider the micron rating of a whole house water filtration system. This measurement indicates the size of particles that can be filtered out by the system; typically ranging from 0.5-50 microns.
For maximum protection from small contaminants like bacteria or viruses, choose a filter with a low micron rating (0.5-10). If you’re mainly concerned about removing large particulates such as sand or silt, opt for one with a higher micron rating (20-50).
Keep in mind, that the lower you go on micron rating can cause water pressure issues and is the main reason why you don’t see to many whole house reverse osmosis systems on the market.
Does it meet NSF standards?

The federal government doesn’t test or regulate water filters. Instead, industry members of NSF International created voluntary, minimum performance and safety standards recognized by ANSI, the American National Standards Institute.
Filters certified:
- NSF 42 remove taste and odor impurities
- NSF 44 soften water by removing hard minerals via ion exchange
- NSF 53 reduce contaminants with known health effects
- NSF 55 kill bacteria, viruses and cysts with ultraviolet light
- NSF 58 reduce EPA-regulated contaminants via reverse osmosis
- NSF 401 reduce on of 15 emerging contaminants not yet regulated such as PFOA and pharmaceuticals
NSF/ANSI-certified whole house water filters are the gold standard for quality assurance. Companies willing to pay for independent testing and certification fees typically provide transparency about their filter’s performance. However, don’t focus solely on certifications; other factors like filter material quality should also be taken into account.
Certified filters offer an additional layer of confidence as they are regularly tested for quality control, so no one gets a “bad batch” of water filters. All things being equal, certifications are an added boost of assurance.

Getting The Best Value
What does it filter out?
The purpose of finding the best home water treatment system for the entire household is to remove unwanted contaminants, so it makes sense to know which pollutants are common problems.
If you have city water, it’s disinfected and safe to drink. But despite EPA regulations, it could contain unsafe levels of:
- Fluoride
- Chlorine
- Chloramine
- Bromate
- Haloacetic acid
- Herbicides
- Pesticides
- PFOA/PFOS
- Industrial solvents
- Volatile organic compounds
- Sediment
- Trace pharmaceuticals and more
Lead, bacteria and parasitic cysts can also enter water through deteriorating underground pipes after leaving the treatment plant.
If you have well water, added fluoride and disinfectants aren’t a risk. But an estimated 20-percent of wells in the US are contaminated and could harbor natural and human-made toxins, including:
- Sediment
- Hard minerals
- Lead
- Arsenic
- Mercury
- Chromium
- Nitrates
- Agricultural chemicals
- Petroleum products
- Industrial chemicals
- Bacteria, parasites and more
Not all wells contain these substances. What’s in your water is determined by local geology and your watershed — the area around your home that feeds your water supply. If you live near a landfill, heavy metals and VOCs are a risk. If you live near a large farm, contamination with nitrate fertilizers, herbicides and pesticides is more common.

The best way to choose a whole house water filter is to know what’s in your water today. City water users can get a quality report from their treatment authority but should test their tap water for lead separately.
Well owners should do a comprehensive test — DIY or via a certified lab. Regardless of water source, you can then shop confidently for a filter that targets the greatest number of problem contaminants.
Understanding Warranties
Choosing the wrong whole house water filtration system can be a costly mistake. Make sure to read the fine print and choose a company/brand that offers an iron-clad warranty and decent return policy – this way you’ll have peace of mind knowing your investment is protected!
Filtration Brand | Warranty | Money Back Guarantee |
---|---|---|
Springwell | Lifetime | 6-month money back guarantee |
Aquasanna | 6 years | 90 days |
Pentair | 650,885 Gallons or 5 years | 60 days |
Ispring | 1 year | 30 days |
3M Aqua-Pure | 5 years | 30 days |
Money-back Guarantees – What You Should Know
Trial periods are great, but make sure to read the terms & conditions. Avoid restocking fees and return shipping costs by opting for a 30/60/90-day trial period. But beware, size and weight can affect return shipping costs and that’s on you!
What does a “lifetime limited warranty” really mean?
Many consumers overlook the fine print when it comes to “lifetime” warranties. Be sure to read all of a company’s terms and conditions before buying so you know exactly what is covered. Often, only tanks are covered while fittings and valves may not be included.
This doesn’t mean the company is bad in any way, it comes down to how much the company is willing to cover.
Are you paying for more than what you really need?
Knowing what could be in your water is scary, but most homes only need selective filtration. Unless a water main breaks or there’s a disaster, you don’t need an expensive system for killing viruses. And if you don’t have hard water, skip the softening capability.
Invest in preparedness only if necessary and consider over-filtering if you can afford it.
Whole House Water Filtration Systems Vs. Reverse Osmosis
Whole house water filtration systems ensure your family always has safe water. Installed near the home’s inlet, it treats every drop used for drinking, bathing, and more. No need to worry about quality — it’s all safe!
Multi-stage systems using sediment, carbon, and KDF filters remove contaminants like dirt, rust, chemicals, and heavy metals. No drop in water pressure; just cleaner looking, smelling, and tasting water.
Reverse osmosis systems produce higher-quality water with an RO membrane to remove even the tiniest particles, but they’re slow and limited to gallons per day. Under-sink RO filters purify drinking/cooking water at the point of use and can remove toxins like fluoride that traditional filtration may miss. Cost-effective for heavily contaminated areas.
Since prices are similar, a whole house water filter may be a better value if it removes target contaminants and treats all incoming water.
Filter Cartridges
Evaluating filter cartridges is difficult as performance ratings are based on average water conditions. Five filters may claim 95% lead reduction but actual performance can vary depending on water quality.
Additional media in a cartridge may improve results, and systems with sediment pre-filters remove large particles that could clog other filters, improving overall performance and longevity.
Similarly, when contaminants are removed “up to” a certain percentage, that could be anywhere between 0-percent and the highest claimed, depending on the total quality of your water. Specifications are helpful, but not ironclad.
Systems like the Express Water Whole House Water Filter and the iSpring WGB32B and WKB32B have sediment pre-filters that remove large particles that could clog other filters in the system — improving their performance and longevity.
Brand | Filter | Annual Cost |
---|---|---|
Springwell | 5 Micron filter | ~$40.00 |
Aquasanna EQ | Pre Filter & Post Filter | $120.00 |
Pentair P600 | 5 Micron filter | $70.00 |
Ispring WGB32B | filter cartridges | $75.00 |
3M Aqua-Pure | Filter Cartridge | $127.00 |

Softening Capability
No filter on our list is an actual water softener, but two have some softening capability that protects appliances. The Aquasana EQ-1000, the Home Master HMF3SDGFEC 3-Stage System have some variation on technology that doesn’t remove minerals, but it prevents them from building up on pipe walls.
It won’t alleviate the other effects of hard water, but in place of adding a separate water softener, it’s a plus.
Pros & Cons to Consider

Pros:
- Enjoy clean, safe purified drinking water throughout your entire home with a whole house water filtration system.
- These systems are designed to remove chlorine and other chemicals used in municipal treatment plants from all the water entering your home.
- Plus, they can reduce sediment buildup in pipes and fixtures that could lead to clogs or reduced flow rates over time.
- Installing a whole house system is often more cost-effective than buying bottled water or individual filters for each faucet in the home.
Cons:
- Whole home water filtration systems require regular maintenance and filter changes to ensure optimal performance at all times.
- The initial installation costs may be higher than those of individual filters due to their larger size and complexity of installation requirements.
- They may not be able to remove all contaminants from the water, so it’s important to research which system best fits your needs before purchase for maximum safety benefits!
Installation & Maintenance

This is a basic overview on how to install a whole house water filter. Keep in mind, the systems we review have video tutorials on their website, and on YouTube.
- Shut off the main water supply to your home and locate a spot for installation of the filter system, such as near the main line entering or in an area with easy access for maintenance and replacement.
- Install shut-off valves on both sides of where you will be installing the filter system so that it can be isolated from other plumbing when necessary.
- Connect flexible tubing to each side of the shut-off valve, ensuring all connections are secure and leak free before proceeding further.
- Attach one end of another length of tubing to the outlet port on your whole house water filter system and connect it to one side of a T-fitting using appropriate connectors; attach another length back into your main water line using more suitable connectors as needed (this is how filtered water enters).
- Connect yet another length from this same T-fitting onto an additional shut-off valve which should then be connected directly to a drain pipe or other drainage point (this is how unfiltered/dirty water exits).
- Insert filter cartridges into housing, making sure they are securely in place and all connections are leak free before continuing onward.
- Turn on main water supply, check for leaks or issues, and test water pressure and flow rate to ensure it is within acceptable limits.
- Once everything is working properly, turn on the shut-off valves connected to the filter system and enjoy purified filtered water throughout your home!
Maintenance
The beauty of owning a tank-based unit is that there’s hardly any maintanance at all, except for changing out your pre/post sediement filters as needed. On the flip side, cartridge based filters require filters to be changed per manufacturers recommendations.
Use our helpful guide to give you a quick run-down:
- Change your filter every 3-6 months: Check the manufacturer’s instructions for specific recommendations based on your water quality.
- Clean the housing unit regularly: Unscrew and remove it from its mounting bracket, then rinse with warm water to remove dirt or debris that may have accumulated over time.
- Inspect all parts of the system: Ensure connections are secure and there is no corrosion or damage to any components of your whole house water filter system.
- Test incoming water pressure annually: Use a pressure gauge to make sure it is within normal operating range (typically between 40-60 psi). If not, contact a professional plumber for assistance in adjusting it accordingly.
- Flush out sediment buildup periodically: Over time, sediment can build up inside pipes which can reduce flow rate and cause clogs; use an appropriate flushing device such as a garden hose or backwashing valve every 6 months to flush out this buildup.
- Check for leaks frequently: Visually inspect all fittings and connections around your whole house water filter system for any signs of leaking or dripping; if you find any, contact a professional plumber for assistance in repairing them immediately.
- Monitor water quality consistently: Test your water regularly to ensure it is free from contaminants and meets all safety standards; if not, contact a professional plumber for assistance in adjusting the filter accordingly.
Frequently Asked Questions
A whole house water filter is only necessary when the water is not safe to drink. However, many non-harmful impurities make the water unpleasant to taste or cook with; thus people often opt for filters to improve its flavor rather than safety.
Yes, they are! Invest in a whole home water filter if your kids don’t enjoy drinking tap water. Hydration is important and filters are usually cheaper than bottled water and healthier than sugary soft drinks.
A whole house Reverse Osmosis filtration system is costly but would remove the most organic molecules, viruses, and particles as small as 0.0001 microns. Traditional under sink reverse osmosis filtration tank media is more suitable for residential use.
Depending on your filtration type, a sediment pre-filter should be changed every 3 to 6 months. A Carbon filter every 12 Months and a post-filter every 12 months.
This entirely depends on the water filtration system you choose. Tank-based filtration media can last up to 10 years or 1 million gallons. Whereas, cartridge based systems can last up to 12 months.
