3. Best for RO Purification: Crystal Quest Reverse Osmosis Under Sink Water FilterIf you use well water for cooking and drinking, the reverse osmosis under sink water filters by Crystal Quest might intrigue you. We’re talking about the 1000C/1000CP in particular. Both are geared towards well water. However, they are not NSF-certified, which is a downside. The units are downright similar except that the 1000CP utilizes an electric pump to enhance water pressure. Above that, the pump decreases wastewater and increases the filtration speed. What else is good? The units include 12 different filter stages to ensure maximum contaminant elimination from your well water supply. Besides, if you want to go a step above and wish to remove 99.9% of microorganisms, you can go for a 13th filter stage and convert the Crystal Quest 1000C/1000CP to the 3000C/3000CP.

Buyer’s Guide – How to Buy an Under Sink Water Filter for Well Water (+ How We Tested)Here’s our buying guide with everything you need to know about how to buy the best under sink water filter for well water. Test Your Water Quality
Well water is free and pretty much endless, which is excellent. However, if you’re getting water supplied via a private well on your property, you need to test it for contaminants. Just a bit more effort and you’ll make your water suitable for drinking. It’s best to test your well water yearly since the concentration and properties of chemicals in your water change over time. A well water test will inform you about potential problems with microorganisms and other bacteria or impurities/contaminants like iron, mercury, and pesticides. After knowing about your water quality, you can choose an appropriate treatment method. Pre-Treat Your WaterYou’re installing an under sink water filter to remove contaminants; what’s the point of pre-treatment anyway? We’ll explain. Your well water may contain disease-causing pathogens like harmful bacteria that no regular under counter water filter can eliminate. Also, the water may be filled with hardness minerals, sediment, iron, and other contaminants that’ll clog any regular point-of-use water filter in no time. So, before your new under sink well water filter becomes useless and the money spent to purchase it goes to waste, it’s often best to pre-treat your water.
Filter CertificationsNSF certifications are hands down the best way to know about the authenticity of an under sink water filter for well water and its ability to eliminate contaminants. This explains why most consumers look for NSF-certified filters. So, when comparing several styles, brands, and models, make sure you go for a water filter certified or tested by NSF. Why? NSF is a non-profit organization that analyzes and certifies items for health safety purposes using stringent criteria. You must look into the following certifications when purchasing an under sink well water filter for your home.
Filtration TechnologiesYour water test report is something that’ll help you determine an appropriate filtration method for your well water. You can go for any of these technologies:
Filtration StagesIn general, the more filter stages, the cleaner your well water will become. Simply put, if you want maximum water purification, you should go for a filter that offers multiple levels of filtration. But, when your water passes through several stages of filtration, its flow rate gets affected, too. So that’s something to keep in mind. Water Pressure and Flow Rate
Water pressure refers to the force with which water flows out of a faucet, whereas flow rate is the amount of water flowing out in a given time frame. Most private wells include a pressure tank that controls the water pressure of your well water supply. Because under sink water filters depend on the water pressure to work, make sure your home water has a pressure of around 60 psi. Poor flow rate reduces pressure and flow from your faucet and may result in poor filtration. Additionally, faucets without filters can supply water at a 1.5-2.0 gpm flow rate[3]. But no water filter system can match this. Generally, under sink water filtration systems include a faucet with 0.5-1.5 gpm flow. InstallationLuckily, most under sink water filters are easy to install, and you can set them up all by yourself. Only for a few exceptions you might need to hire a professional. If you’re going for the latter option, expect to pay around $200 in installation fees. Besides, we recommend you take opinions from two or more plumbers. Otherwise, you might end up paying a hefty amount for work that’s easy and takes no more than an hour. Also, note that under sink filter systems with a dedicated faucet cost more for installation. However, we recommend you go for one to utilize unfiltered water for washing vegetables or doing the dishes. This practice will ensure your filter lasts longer and requires less maintenance. MaintenanceBecause you’ll be replacing filters every six months, make sure you go for an under counter system that has easy-to-change cartridges. Otherwise, you might end up spending hours just to remove a filter cartridge. So besides saving time, an easy-to-maintain filter will also save you money by eliminating service charges. Price Meets Filter CapacityWhen purchasing an under sink water filtration system for your home, make sure you estimate the total average annual replacement cost. Because if you’re buying an inexpensive filter that needs frequent replacements, you may actually end up paying more in the long run. That said, most of the under sink well water filters available on the market require replacement every 6 to 12 months. SpaceUnder sink filters typically fit well inside any kitchen cabinet. However, if you’re out of space, make sure you purchase one that takes little room. For instance, inline filters take less space than RO systems using multiple filtering stages. AffordabilityLastly, don’t forget to consider your budget when purchasing an under sink filter for your well. It’s time to debunk the myth that more expensive filters indicate a quality product. Although this can be the case, an affordable filter with fewer features might be just enough for your water conditions and needs. Thankfully, you’ll find plenty of cost-effective options on the market. A simple under-the-sink filter can cost you as low as $80, whereas some heavy-duty systems come in at around $400-500. What is an Under Sink Water Filter for Well Water?
Under sink water filters provide filtered water on demand. You won’t find many filtration systems designed specifically for well water, though. Ideally, it’s best to go for a regular under sink filter system alongside pre-filtration. In many cases, private well water is high in iron, sediment, scale, or other contaminants. If your water is, too, it could block any under sink water filter system quickly. Therefore, it’s best to pre-treat your well water. Under Sink Well Water Filter Types and How They WorkBelow, we’ll discuss a few under sink water filter types that you can use for your well water. Dedicated Filtered Water Dispenser vs InlineAn inline under sink filter will connect the filter cartridge directly to your existing tap. While the idea of a single tap sounds enticing, you do not require filtered water all the think, i.e. for doing the dishes or washing vegetables. This is why some under sink water filters come with a separate faucet. You can set up a dedicated dispenser to minimize wasting filtered water. What’s more, this practice will prolong your filter’s life. Single-Stage FiltersThe simplest under sink well water filtration systems features a single filter cartridge/stage. However, you shouldn’t underestimate their usage. I mean, if your well water has no microbes and you’re already on a whole house sediment water filter, a simple carbon filter may suit you best. Multi-Stage UnitsMost conventional filtration systems use multiple stages to filter water. A few have two stages, while more advanced filters have three or even more. Multi-stage water filters ensure maximum filtration, but they may lower pressure and flow rate. Reverse Osmosis SystemsAn RO system is perhaps the best option for people on private wells. It treats your water to a molecular level. Conversely, reverse osmosis systems remove healthy minerals alongside the bad stuff. Besides, RO systems are not that eco-friendly, which is another bummer. On average, 3 to 4 gallons of water flushes down for every filtered gallon – without a pump. Benefits and Drawbacks of Under Sink Filter Systems for Well WaterBelow, we’ll discuss what we love about under sink well water filters and things we do not idealize. Advantages
Disadvantages
Who Should Purchase an Under-the-Sink Water Filter?If you suspect your water is contaminated, you should consider installing an under sink filter system regardless of whether you’re on a private well or city water. Installing Under Sink Water FiltersIf you’re a semi-technical sort of person, installing an under sink water filter should be easy as pie for you. Nonetheless, if your filter comes with a dedicated faucet, you’ll need to drill the sink top, of course. However, if your filter is DIY-installation friendly, you can save up costs by doing the job all by yourself. Here’s how.
How to Maintain an Under Sink Water FilterUnder sink filters can last for 6-12 months, depending on the filter cartridge you use. Make sure you keep track of your daily water usage. Your water quality also determines the lifespan of the filter. If your well water is highly polluted, it’ll clog the filter much faster. Private Well Water: Under Sink or Countertop Filters?There’s not that much of a difference between under sink and countertop water filters. Obviously, one goes under your kitchen counter while the other is placed above it. Prices are almost the same which also goes for the available filter methods. Which Type to Choose?Simply put, if you don’t have the necessary space under your kitchen sink to install a water filter system, go countertop. Vice versa, if your kitchen counter is already cluttered with a microwave, blender, coffee maker and other appliances, do yourself a favor and install an under sink filter system. Frequently Asked Questions (FAQ)

If it’s contaminant-free and tastes good there is no need for a water filter.

The same applies if a water test has shown harmful contaminants to be present in your water supply. How do you clean an under sink water filter? You can’t clean the filter cartridges. All you can do is wash the filter housings from the inside using a mild dishwashing detergent. Does an under sink water filter for well water limit the flow rate? If it’s a simple sediment filter then you’ll see almost no difference in flow rate. But the more thorough the filtration is, the more it will limit output water pressure and flow.
