Water softeners or water conditioners are the best way to overcome hard water issues. However, they barely improve water quality in terms of potability. Water filters, on the other hand, are great for removing harmful contaminants as well as taste and odor, but most don’t do much when it comes to the removal of hardness minerals.
In other words, oftentimes you need both a water softener AND a water filter. What is the best whole house water filter and softener system? This buying guide features a collection of our favorite combos. Ready to find your ideal setup? Let’s go!
1. Best Whole House Water Filtration and Softener System for City Water: SpringWell CSS or CSF (Salt-Based vs. Salt-Free Softening)
SpringWell is our top pick for both whole house water filtration and water softening. Naturally, if you’re looking for a combination of the two we highly recommend you opt for SpringWell.
For city water, you can choose between the SpringWell CSS and the CSF filter-softener combo. Both use the same catalytic carbon filter to remove chemicals and organics among other water contaminants, turning even the nastiest tap waters into great-tasting drinking water.
The difference, however, is that the SpringWell CSS relies on a traditional salt-based water softener to remove hard water minerals, while the SpringWell CSF includes a salt-free water conditioner to reduce scaling. Both combos have proven to be highly effective at what they do. Thus, it really depends on your personal preferences which one to choose. We like either one. 5 stars!
SpringWell CSS4 Whole House City Water Filter + Salt-Based Water Softener
5-micron pre-filter is a physical barrier for sediment. Prevents clogging of the rest of the system.
Whole house water filter is filled with catalytic carbon and KDF. The carbon removes chlorine, chloramines, volatile organic compounds (VOCs), pesticides, disinfection byproducts, and more. The KDF takes care of various heavy metals (e.g. lead) + it controls the growth of microorganisms.
You get clean & healthy, refreshing, odor-free water. Perfect for cooking, drinking, showering, and washing.
SpringWell guarantees chlorine/chloramine reduction below the minimum detection level for 1,000,000 gallons or 6 years.
SpringWell Salt-Based Water Softener Only:
Ion exchange water softener replaces hard minerals (calcium, magnesium) in water with sodium. This makes it soft.
Most effective treatment method to eliminate scale buildup in your home.
Entire plumbing system, fixtures, and appliances will work more efficiently and last longer. Less maintenance requirements, fewer repairs.
Your hair and skin will look and feel better. Laundry will be softer.
Upgraded 10% crosslink softening resin lasts up to two times longer than standard resin which is less chlorine resistant.
Digital head unit controls water softener system regeneration.
Bluetooth compatible: Can be connected to phone/tablet via app (available for iOS and Android). Allows for easy configuration of regen cycle frequency, length of backwashing, and salt dose.
Control valve measures water use and adjusts the amount of water and salt that will be used during next regeneration. Vortech plate improves backwashing efficiency.
Saves resources. (And money!)
Water softener is fully NSF-certified for structural integrity.
Choose from 3 different sizes:
CSS1 combo provides a water flow rate of 9 gallons per minute. For homes with 3 bathrooms maximum. Water softener: 32,000 grains.
CSS4 is rated at 12 gallons of water per minute service flow. Ideal for 4-6 bathrooms. Softener: 48,000 grains.
CSS+ is the largest and only makes sense for a house with 7 or more bathrooms. 20 gpm. 80,000-grain water softener.

2. Best Whole House Water Filter and Softener Combo for Well Water: SpringWell WSSS or WSSF (Salt-Based or Salt-Free Softener)
As mentioned before, SpringWell is our top recommendation for people looking for a whole house water filter and/or whole house water softener. So it only makes sense for us to recommend SpringWell if you want to combine the two.
If you’re on well water, your best option is probably the WSSS or the WSSF series. They’re perfect for water containing iron, manganese, or hydrogen sulfide (rotten egg smell), or a combination of the three.
Apart from filtration, your water will also go through a softening stage. Actually, only the WSSS combo uses a “real” salt-based water softener, whereas the WSSF setup applies a salt-free water conditioning system. Both effectively reduce scaling but the latter won’t remove any hardness minerals from the water doing so.
Which filter-softener combination should you choose? This is a matter of personal preference. Each has their own benefits (learn more below). Personally, we like them both. 5 stars!
Side note: In case there’re a lot of chemicals and organic contaminants in your well water you might want to consider adding the SpringWell catalytic carbon filter on top. It’ll not only greatly improve water aesthetics (odorless, clean taste), it’ll also make your water perfectly safe and healthy.
SpringWell WSSS4 Whole House Well Water Filter + Salt-Based Water Softener
SpringWell WS whole house well water filter system eliminates rust staining in toilets, sinks, showers, etc. and unpleasant sulfur smell. The filtered water will also taste much better.
Combines air injection oxidation with greensand media filtration to remove maximum combined of ferric & ferrous iron (7 ppm), manganese (1 ppm), and hydrogen sulfide (8 ppm). Also reduces arsenic and radium.
Safe for septic and sewer systems.
Digital head unit resets air pocket daily + backwashes greensand media periodically to flush out all accumulated contaminants. No need for you to worry!
Can be connected to your mobile device via Bluetooth for programming.
SpringWell Salt-Based Water Softener Only:
Water softener removes hard water minerals and replaces them with salt. Little to no remaining water hardness.
No more scaling in your home’s plumbing, appliances, and fixtures. Water heater will work more efficiently. Overall less maintenance requirements and fewer repairs.
Soft water is gentler on your hair and skin (and clothes).
10% crosslink resin is more resistant to chlorine in case you shock your well.
Digital head manages system regeneration fully automatically.
Bluetooth functionality allows for easy programming of cycle frequency, backwashing length, salt dose, etc.
Metered regeneration + Vortech mineral tank plate save water + salt. Highly efficient!
Only NSF-certified parts are used.
Whole house water filter-softener combo comes in 2 sizes:
WSSS1 version is for homes with 1 to 3 bathrooms (11 gpm flow rate). Softener size: 32,000 grains.
WSSS4 version is designed for any 4 to 6-bathroom household. Softener size: 48,000 grains.
SpringWell Water Conditioner Only:
Sediment pre-filter protects conditioning tank from fouling.
Saltless water conditioning system crystallizes hardness minerals. In crystal form they can’t attach themselves to surfaces – think pipes. Scale formation reduces by up to 99+% (scientifically proven).
Protects your home’s entire water system from scaling. Existing deposits will vanish over time.
Any remaining scale is soft and easy to clean.
Conditioned water is better for hair & skin but doesn’t feel slippery.
No salt. No chemicals. No regeneration. No change in water pH. Great for you, your home, and the environment.
Catalytic media has no expiration date.
Max hardness level that can be handled is 81 gpg which is considered extremely hard.
Choose WSSF-1 whole house well water filter and salt-free water softener combination if your home doesn’t have more than 4 bathrooms. Water flow rate: 12 gpm.
Choose WSSF-4 combination if you have more than 4 bathrooms. Water flow: 15 gallons per minute.
Tanks come in neoprene sleeve for protection.
Designed for DIY installation but you need to be handy with tools.
Both water filter and softener combos are maintenance-free. You just need to fill brine tank with new salt or replace the sediment pre-filter of water conditioner every 6 to 9 months. Cost: ~$40 per year.
Everything is backed by 6-month money-back guarantee + lifetime warranties.
SpringWell support is responsive, helpful, and knowledgeable.
Some fittings are plastic. We would have preferred metal.
Granular activated + catalytic carbon to adsorb chlorine, chloramine, pesticides, pharmaceuticals, industrial solvents, disinfection byproducts, benzene, and other related contaminants.
Two different Eagle Redox Alloys to remove heavy metals like lead and chromium, more water disinfectants, and hydrogen sulfide (rotten egg smell). The copper-zinc blends also control growth of bacteria + algae.
Ion exchange resin to reduce even more heavy metals and inorganics.
Ceramic and tourmaline balls to adsorb any remaining impurities, especially metals. The balls also help balance water pH and are supposed to aid human metabolism.
Coconut shell carbon block post-filter (5-micron nominal) removes VOCs, pesticides, etc. and cleanses any residual tastes and odor.

Choose 1,500,000 gallons filter + 64,000-grain water softener if you have 4 bathrooms or more. Water flow: 10-13 gpm.
Optional: Upgrade fiberglass to stainless steel tanks for looks and longevity.
Self-installation is doable but certainly a bit more demanding.
Maintenance requirements are low.
Filtration and softening media last up to 10 years, depending on your daily water usage and feed water condition.
Additional filter cartridges last 12-18 months, maybe a bit longer. Average annual cost: ~$40-65 which really isn’t much.
Refill brine tank with salt if you opt for traditional softener.
Crystal Quest warranty all its systems for 1 year.
Not the most affordable option out there.
Water conditioner might require pre-treatment of water if iron, manganese, copper, phosphate, or hydrogen sulfide content, or hardness level is too high.
Best to contact Crystal Quest support team about this (they have a live chat!).
4. For Small Budgets: FilterSmart FS1500 – Activated Carbon Filtration + Salt-Free Softener
The main selling point of the FilterSmart FS1500 is certainly the low price. For well under $2,000, you get an activated carbon whole house water filter paired with a salt-free water softener a.k.a. conditioner.
The combo will give you access to considerably cleaner drinking water throughout your entire home. And it’ll solve your hard water problem – definitely worth checking out! 4 stars.

5. For Even Smaller Budgets: Tier1 Whole House Water Softener + Point-of-Use Reverse Osmosis Drinking Water Filter System #Cheap
Tier 1 whole house water softener + point-of-use reverse osmosis drinking water filtration system. This is by far the most affordable solution when you want to combine water filtration with softening.
Both systems are designed for the mass market, mind you, so don’t expect outstanding quality. And there’re other trade-offs that you must expect in this price segment (more on this in a bit). That said, both units still get the job done – soft water throughout the entire house and filtered water ready for drinking straight from the kitchen faucet – guaranteed! 4 stars.
Tier1 Whole House Water Softener + Point-of-Use Reverse Osmosis Drinking Water Filter System #Cheap
Tier1 Everyday is a genuine salt-based water softener. Removes hard water minerals (calcium and magnesium) from water for little to no scaling.
Capacity is 48,000 grains. 11.2 gpm water flow. Suited for small to mid-sized homes with up to 4, maybe 5 bathrooms.
Protective neoprene tack jacket is part of the package.
Tier1 RO5 under sink reverse osmosis system filters water at the point of use.
Produces clean, pure drinking water.
Uses sediment and carbon block pre-filters, RO membrane, and GAC post-filter.
5-stage filtration process removes or reduces sediment and other particular contaminants, chlorine, taste and odor, chemicals, and the vast majority of dissolved solids (i.e. arsenic, chromium 6, fluoride, lead, cysts, nitrates, radium).
Water is stored in 3.2-gallon storage tank and can be dispensed using dedicated chrome faucet. Enough water for family use.
4 reusable glass water bottles are included.
Both water softener and RO should be easy to install. There are printed installation instructions and video guides.
Dedicated water dispenser of RO system requires hole in countertop or sink, so you need to drill one if there isn’t a spare one. You’ll definitely have to drill into the drain line of your kitchen sink.
Maintenance is simple: Refill water softener brine tank with salt and change RO filter stages every 3 to 6 months. RO membrane itself lasts up to 2 years.
Manufacturer provides satisfaction guarantee on water softener for the first 90 days after purchase (only valid if water is within stated specifications).
One-year warranty on water softener control valve + tank. Lifetime warranty on RO unit.
8% crosslink softening resin is less chlorine-resistant and wears out quicker when used on chlorinated city water supply.
Water softener installation instructions could be better.
Programming the digital head unit requires some getting used to.
Bypass valve is manual so water service disrupts during regeneration. 1 cycle takes about 2 hours.
Not an issue when you set frequency to weekly and at night time.
Some parts of the reverse osmosis system feel a little cheap.
Buying Guide: How to Choose the Best Whole House Water Filtration and Softener System
Test Your Water Quality
The best approach to finding the ideal water filter and/or water softener always starts with finding out more about your water quality. If there’s no recent quality report (check here or here) for your water supply you need to have a direct sample tested by an independent lab. Or you purchase a test kit and do the testing yourself to get a rough idea of what you’re facing.
Choosing the Ideal Water Filter
Primary Filter Media
If your water is high in sediment get yourself a sediment (pre-)filter.
For chlorine, chloramines, and all sorts of chemicals and organics commonly found in tap water you want to install a carbon water filtration system. Carbon is also great for neutralizing off-taste.
Iron water filters are designed for the removal of iron, manganese, and sulfur.
KDF is not only bacteriostatic, it also reduces disinfectants and a bunch of heavy metals.
Choosing the Ideal Water Softening System
Water Softener or Water Conditioner
There’re salt-based water softeners that use ion exchange to replace hardness minerals in water with sodium or potassium. And there’re salt-free water conditioners that apply different technologies to reduce the scaling effects of hard water without adding or removing anything from it.
The former are still the industry standard and preferred choice of most home owners due to their effectiveness. But, water conditioners are getting more popular as they’re becoming more sophisticated delivering better and better results.
Personally, we like both. If we were to go with a water conditioner, though, we would make sure it uses Template Assisted Crystallization.
Water Softening Capacity
Salt water softeners need to regenerate in order to replenishing their softening resin. The amount of grains that a system can remove between two regeneration cycles is its capacity. Depending on its size, capacities start at 8,000 hardness grains (portable water softeners) and can reach 80,000 grains (whole house systems) and higher if need be.
Simply put, your new water softeners needs to be large enough to handle your water hardness level and demand.
Both whole home water filter and softener need to be able to process enough water to supply your entire household – kitchen, bathroom(s), appliances…
If that’s not the case your water pressure might drop when you use too many water outlets simultaneously, or raw feed water could bleed through.
10-15 gallons per minute water flow is pretty standard for whole house applications.
Look out for NSF Standard 42 in whole house water filters. It guarantees effective chlorine reduction.
NSF Standard 44 was established for cation exchange water softeners and covers things like salt and water efficiency, and most importantly the effective reduction of hard minerals.
It might seem obvious, but don’t underestimate the size of a whole house water filter and softener next to each other.
When it comes to cost, the initial price tags of a whole house water filtration system and softener are important, but so are operating/maintenance cost. Not all filter cartridges/media last equally long. And some are cheaper to replace than others.
As for water softeners, remember to take into account the expenses for salt and water required for regeneration (salt-based systems only). Compared to something super cheap, a more expensive but more resource-efficient unit likely turns out more cost-effective in the long run.
All-in-One Water Softener and Filter
We’re not fans of all-in-one water softeners and filters. First of all, they’re really rare. And second of all, they’re usually much less effective and efficient than separate filters and softeners set up in sequence.
One of the reasons is that proper water treatment takes time – contact time between the water and the filter media and the softening resin. Providing less of both, an all-in-one water softener and filter simply cannot keep up with two large separated systems.
