TDS is an abbreviation for total dissolved solids. They represent the total concentration of dissolved substances in the water, made up of inorganic salts and minimal organic matter. Such inorganic salts include calcium, magnesium, potassium, and sodium.
Anions included are such as carbonates, nitrates, bicarbonates, chlorides, and sulfates. Cations are positively charged ions and anions are negatively charged ions. These minerals get into your water through natural resources such as mineral springs or human activities such as agricultural and urban runoff.
These runoffs carry excess minerals into water sources. Increased TDS concentrations can cause technical effects, thus producing hard water, which leaves deposits and films on various fixtures. However, a low concentration of TDS gives water a flat, undesirable taste.
The United States guideline for TDS is 500 parts per million(ppm). Therefore, you should install the best water purifier or filter, such as a reverse osmosis system. They come with a combination of UV and UF filters that ensures your water is 100% contaminant-free.
So, what is the best water filter for high TDS?

Factors to Consider When Buying a Water Filter for High TDS
Total dissolved solids(TDS) in your water consist of minerals that you might prefer to eliminate from your drinking water. You will need a water filtration system that will remove almost all the contaminants, heavy metals, and TDS. Such filtration systems that can filter these contaminants are the reverse osmosis systems.
The market for reverse-osmosis systems is surprisingly large and varied. To find the right one for your needs and budget, here are a few key factors to consider;
1. The Price
You should prioritize how much you’re willing to spend. Reverse osmosis water filters range in price from around $150 to over $1000. The more expensive ones often use more water filters and can filter larger quantities of water at a time. They also have extra features like autoflush.
In some cases, the higher-end systems can put more valuable nutrients back into the water after the harmful ones have been filtered out. You are more likely to end up with a low-quality RO water system that won’t last long if you choose to purchase a cheap one.
However, any mid-range products will get the job done well enough for most people’s needs, and the higher-end options can add in some nice-to-have features.
2. The Size of the Water Filter
Whether you buy a countertop or under the sink reverse osmosis system, the space you have available for it is an important consideration. If you have limited counter space in your kitchen already, then a sizeable reverse-osmosis system will add to the space’s clutter. An under-counter reverse osmosis system has to fit in the area you have under the sink.
If you purchase one that’s too big, you’ll have to resend it and start from scratch. Therefore, measure the space you have available and check it against the dimensions of any system you’re considering. If you’re worried the one you want might be a tight fit, check with an expert who can weigh in on how the size will affect their ability to install it properly.
3. Amount of Water
Another factor related to size is how much you can filter your reverse osmosis water. Each RO system will provide information on how many gallons of water a day it can handle. The most standard sizes in the market are 50 to 100 gallons.
If you have a relatively small household, then the 50-gallon system should work for you. If your family is large and uses a lot of water, then bumping up to a whole house system is a smart bet.
4. Its Effectiveness
You are likely to come across a lot of reverse osmosis systems that reference several stages. It refers to the number of filters the system uses to remove particles from the water. For example, a four-stage system may include a sediment filter, a carbon filter, a reverse osmosis membrane, and a post-carbon filter.
At the end of all those stages, you can likely count on your water being clean and tasting great.
Depending on the state of the water you’re starting with, you may not need five or six stages, but if you want the confidence that your system is doing a complete water filtration, those extra stages may be worth the investment.
5. The Ease of Installation
You may want to call in a professional to install your reverse osmosis system, mainly if you buy an under-the-sink one. How difficult an installation job is will influence how much you need to pay for the job or how much time you spend if you decide to do it yourself.
When purchasing a reverse osmosis water filtration system, make sure you check for the DIY installation Dvd from the manufacturer if you are planning on personally installing it.
Therefore, you should consider a water filtration system that’s pretty straightforward is likely in your best interest.
6. The Ease of Use
If you buy a reverse osmosis system, it will be pretty simple to use every day, but you will have to do some work to keep it in excellent working condition. Always ensure to check how often a system’s filter needs to be replaced.
You should also check how complicated it will be to clean before deciding which water filter to buy. If you know you’re the kind of person to begrudge having to deal with replacing a filter every other month, then go for a model that only needs a replacement once a year.
Therefore, you will need regular maintenance for your reverse osmosis system to do its job and last a long time.
7. Overall Waste Created
One of the downsides of reverse osmosis systems is that they create a lot of water waste to deliver clean water to you. Many systems only recover about 5-15% of the water they filter. In general, that extra water use is simply a necessary effect of getting cleaner water to drink.
Some systems are designed to reduce water waste by repurposing it toward other uses, like dishwashing or laundry. These are touted as zero-waste systems. Suppose you’re okay with having clean water to drink but using water with more chemicals and sediments for other household uses. In that case, these are the best choice you have for using reverse osmosis without wasting water.
8. The Lifespan of the Water Filter
If you’re going to invest in a reverse osmosis water filtration system and go to the trouble of having it installed, you want to know you can count on it for years to come. Going with a well-regarded brand and a product with solid reviews is your best bet for finding a system that will last you for a long time.
Make sure you choose a water filtration system that comes with warranties, including limited lifetime warranties in some cases. If you want to be confident that you won’t be dealing with a broken or worn-out system soon, you can opt for one that offers a solid warranty.
With these tips in mind, you can confidently purchase a water filtration system that will get you clean and great-tasting water.
Frequently Asked Questions
1. Does water filter reduce total dissolved solids (TDS)?
Reverse osmosis eliminates virtually all TDS or should reduce it to a deficient level of less than 50ppm. If your TDS is above 500 ppm, this will be the best water treatment method to reduce or remove TDS from your water. A TDS level above 2,000 ppm is entirely unsafe to use or drink.
2. How do you get rid of high TDS in water?
Water treatment facilities can use reverse osmosis to remove the water’s dissolved solids responsible for elevated TDS levels. Reverse osmosis removes virtually all dissolved substances, including many harmful contaminants, minerals, such as salt and lead. You are assured of the excellent quality of your water.
3. Does Brita filter remove TDS?
Brita filter pitchers remove 60 contaminants from the water they filter but don’t make claims about reducing total dissolved solids (TDS). Brita filters do reduce TDS, but not significantly. It’s so sure of its filtration that a TDS meter for TDS reading is included so you can always see for yourself.
4. What should be the TDS of filtered water?
Total dissolved solids are acceptable in your drinking water. However, the TDS level in the range of 80-150 is considered ideal. If you are using a reverse osmosis water purifier, make sure the TDS level of purified water is not below 80 mg/L.
5. What happens if you drink high TDS water?
While these solids may not affect human health, they can cause technical damage to your home’s plumbing and surfaces. Elevated TDS levels can indicate corrosive water. If drinking water has high corrosivity, it will often contain high amounts of chloride, iron, copper, manganese, or zinc.
6. How much is a whole-house reverse osmosis system?
Whole-house reverse osmosis systems usually range from $12,000 – $18,000 as an installed price. The cost depends on several factors but is most closely linked to the amount of water that needs to be generated per day.
7.Which is better reverse osmosis or carbon filter?
Carbon filtration excels at removing chlorine taste and odor. It also does a great job of capturing large particulates. On the other hand, Reverse Osmosis will remove almost anything from your water, but it works better if the large particles are removed ahead of it to prevent premature fouling of the membrane.
8. Do I need reverse osmosis if I have a whole house filter?
RO treatment works differently – in part because most systems purify your water in addition to filtering it. They remove contaminants from all of the water you use to drink and cook. Whole-house systems, on the other hand, generally don’t use RO. That’s because they don’t need to.
9. What is a TDS meter used for?
A TDS meter is a small hand-held device used to indicate the total dissolved solids in a solution, usually water. Since dissolved ionized solids, such as salts and minerals, increase the solution’s conductivity, a TDS meter measures the solution’s conductivity and estimates the TDS from that reading.
10. What happens if you drink low TDS water?
Loss of calcium, magnesium, and other essential elements in prepared food. Possible increased dietary intake of toxic metals. Distilled and low mineral content water (TDS < 50 mg/L) can have negative taste characteristics to which the consumer may adapt with time.
