What is a Well Water Filtration System?

The well water, as mentioned, has a high probability of having harmful contaminants in it. A whole house well water system will have a series of filters designed to remove most of the contaminants from the water entry point of your house. The benefit of installing at the entry will save your plumbing pipes and valves from any damage due to the minerals in the water, and it will also keep your showerheads, sinks, and taps free from lime scales caused by hard minerals.

These well water filters are available in a wide range, and you can choose one based on the high level of a specific contaminant in the water. Some filters are specially designed to remove the high quantity of specific contaminants.

These water filters remove hard minerals, toxic chemicals along with VOCs, lead, and heavy metals from the water.

Before choosing a water filter, you should test your water and see the level of contaminants. If any specific toxin or metal level is high, then you can go for the one that will specifically attack that contaminant more.

Why Should You Get a Well Water Filter System?

The quality of water is ensured when the water is coming from the municipality because they follow the strict regulation set by the EPA for public health, which makes you worry-free. After all, you know that the water coming to your house will be safe to use.

When you use the water from wells without filtering, then you may not know, but it may contain harmful parasites and chemicals that may have leached into the water from the surroundings. You can always check for the quality of water, but with the rapid change in the industry, the well water isn’t going to be safe for longer.

When you use the water from a private well, you don’t know the quality of it because there are no regulations to follow for the well water. Many homeowners believe that the water from the well will be safer since the soil acts as a natural filter. But the truth is, according to the study conducted in 2009 every one well from five had a dangerous amount of toxins and disease-causing bacteria.

YouTube video

The well water may contain bacteria, viruses, parasites, heavy metals, radionuclides, fluoride, and even more harmful things. If the minerals and other chemicals are present in small quantities then they will change the taste and odor of the water in small quantities, but when the large amount is present, it becomes risky for you, your family, and also for your water appliances.

If you don’t have a premium well water filter, then these things will have an open way to get into your house and can drastically affect the health of your loved ones and water appliances.

Different Types of Water Filter Systems

There are mainly two categories from which you can choose the water filter. These categories are based on the place of use, where the filter purifies the water.

It can either be under the sink or at the water entry point on the mainline. The filters which are on the mainline are known as “Whole House Water Filters” because they remove most of the contaminants from the water before it enters the house, and the pure water is available for use in every tap and faucet. The filters used at a specific place are known as ” Point of Use ” filters, which provide filtered water at only that point.

Filters are furthermore divided by the type of contaminants and how they are removed. A whole house water filter is made up of different stages, which are a combination of these different filters to achieve the best results. To know more about the different types, keep reading.

Activated Carbon Filter

An activated carbon filter is used as a pre-filter to protect the next filtration stages. It removes the fine silt and sediments from the water.

The carbon filter works by absorbing contaminants permanently from the water, so it is no longer present in the water. The efficiency is determined by the quality of a granule, and a granule vaguely means the smallest particle of substance, which results in a large particle.

The use of carbon for the absorption of toxic materials like heavy metals, chemicals, and pesticides is justified because the surface area of a single gram of carbon is 32,000 square feet. This makes it very efficient at absorbing the particles and gives it a longer lifespan.

Sediment Filter

The sediment filter is a mechanical filter, which means it removes the particle by physically blocking it. The main function of a sediment filter is to remove the large particles so that they don’t reach the upcoming stages and clog them.

The size of the particle it can remove depends on the opening of the pores in the filter. Generally, the rating to this type of filter is given in terms of a micron. It indicates that particles that are bigger than a certain size will be blocked by the filter.

The ability of this filter varies based on the type of blocking structure and material used. It can be as simple as a mesh structure, or it can be highly complex pore structures that not only remove particles but also remove ultra-small pathogenic organisms.

If the rating of the filter is 5 microns, then it will remove particles that are visible to the naked eye. While the rating of a 1-micron sediment filter will remove the particles which you can’t see with the naked eye or can barely see through a microscope. Moreover, there are also filters available which remove particles of the size up to 0.5 microns, with this rating it can remove most of the suspended particles along with cysts.

Note that this filter doesn’t remove any bacterias, minerals, or chemicals present in the water.

Reverse Osmosis Filter

Reverse osmosis systems are highly efficient water filters, and they remove most of the contaminants from the water. Even if some particles are escaped from the sediment and active carbon filters, then they are removed here. This is because this filter has the smallest pores, which won’t let even the tiniest particles pass through.

The reverse osmosis filter system removes fluoride, hexavalent, chromium, arsenic, nitrate, copper, and if you have a water softener installed before the filter, then it will remove the salt as well. It can also remove some of the pathogens from the water, but not all.

The working mechanism is simple; it uses a permeable membrane. On the one side of the membrane stays the contaminated water, which is made to pass through with the help of pressure. The water can pass through the membrane but not the particles, particles stay behind, and you get the clean water on the other side.

The downside of this filter is that it is a slow process, I mean extremely slow. Moreover, it will also create wastewater during the filtration process. The slow process of filtering will result in decreased pressure at the tap, and the wastewater will increase the water bill.

UV Water Filters

UV water filters are the most prevalent filters. They are most effective in removing the disease-causing bacterias and viruses from the water.

With the help of ultraviolet light, the removal is done. The water which is contaminated is exposed to the high radiation, which will neutralize the bacterias. Once they are neutralized, they can’t reproduce, and bacterias that can’t multiply themselves are not capable of making you sick. This treatment of pathogen removal is the highest level of filtration process to remove micro-organisms.

The plus point of this filter is that you won’t have to pour any additional chemical into the water or heat it. Another thing to note is that they only remove viruses and bacterias so, it is always used in combination with other filters to remove other contaminants.

Choosing the Right Well Water Whole House Filtration System

The choice of the right whole house filter system for well water depends on many factors. Before you purchase any filter, you will have to first know what kind of contaminants are present in your water and in how much quantity. To determine that, you can use separate kits available in the market or send the water sample to the state lab.

The well water will mostly contain the leached chemicals, a high amount of hard water minerals. And one study shows that most of the well water will have E.coli or coliform bacteria present in it. So make sure that the filter that you choose can remove these contaminants effectively.

Also, keep in mind that different whole house filters will have a combination of different filter stages so choose the one which is most suitable to remove the contaminants present in your tap water. Before buying a filter, check the fine details about the contaminants each filter stage can remove.

Moreover, the size of the whole house water filter will mainly depend on the size of the family. A filter should provide you with enough flow rate that everyone in your house should be able to use the water without the pressure drop. A good way to calculate the flow rate is to know the flow rate of all the taps and faucets which are simultaneously going to stay on. The filter should provide that much flow rate, to the least.

What to Consider When Buying a Well Water Filter?

Water filter companies flood the market every year with so many water filters. They vary significantly from each other in terms of their size and the technology used to remove the contaminants. And it isn’t an easy task to choose the one for your specific needs. It will be helpful if you keep these things in mind before purchasing a water filter to treat the well water.

Daily Usage

The consideration of your daily need is inevitable, because without knowing your daily needs, if you purchase a water filter which can’t supply enough water, then it will be useless.

The water needs depend on the number of family members. If your daily water needs are high, then you will need to buy a water filter that can supply enough water to fulfill all your water needs. You will need a filter that provides a high flow rate and can filter a large amount of water in less time.

If your daily need is less, in essence, for smaller families, you can go with the small water filters. A good rule of thumb to follow when choosing a well water filter is to go for one which produces more water in an hour than the number of family members.

Budget

Before you start your search for the best well water filter, you must have a budget in mind as it can simplify many things. Once you have a number in mind, you can go for the one which suits your needs based on the water quality. It will also help you to go for the alternatives which can do the job rather well if your budget is low.

We always recommended going for the highest quality filter that you can find because here, you are compromising your health. If you can’t find the one which suits your needs in the budget you chose, then your budget should be flexible.

Contamination

When selecting a water purifier, as I have mentioned several times by now, you will need to first check the amount and types of different contaminants present in the water.

If it contains a high amount of solid metals, VOCs, and chemicals, then the water becomes alarmingly dangerous to be drunk by a human being. Also, the high amount of nitrate, if present, raises great concern.

The solution is to use the purifier, which is specifically designed to remove specific contaminants. If the water contains a high amount of bacteria, then you can go with the UV filter. This filter will neutralize those bacterias by strong radiation from a UV lamp. If bacteria is not your concern, then you can go with the RO filter, which will filter out most of the toxic content through its membrane.

There are filters available in the market that combine both UV and RO filtration stages in a single filter, so you don’t have to purchase two separate filters. Another option is to go with the UF filter, which is best when you have a TDS-free water supply and removes most of the suspended bacteria from the contaminated water.

Electricity

Water filters are available in different sizes and types. Some use electricity, and some don’t. The filter which can work without the electricity is suitable to use when there is a problem of frequent power outages, or power doesn’t stay available for long periods.

RO and UV filters are most efficient to remove most of the contaminants from the water, and they work on electricity. UV filters use electricity to produce the radiation for the removal of pathogens, while in RO filters, the pressure is created with the use of electricity.

If you have any one of the two and you don’t have electricity, and then you will have to arrange for an alternate power source for them to work.

We suggest that you go with the electric purifier because they remove almost all the contaminants which are hazardous to human health. On the other hand, purifiers which can work without electricity are not that effective. They can remove only some of the chemicals and germs along with the sand and suspended particles.

Legitimacy

When you are approached at your home by a filter salesperson, then it is a red alert that you will need to be careful Because in recent years, there are many reports of water purifier scams, and most of them were from lone salespersons convincing you to buy their water purifier. It is not that all salespeople who sell water purifiers are there to scam you, but you can’t take a risk with your health.

Water purifiers became the essential part of life that keeps you healthy, but with the increasing demand, there is a rise in a number of companies who provide water purifiers at cheap price, and no quality checks have been performed on them.

So, to be on the safe side, always buy the water filters from the registered franchises and also check the customer’s reviews online. There is no better source to check the quality of the product and services offered by the company than customer feedback.

Moreover, always check the detailed description of the contaminants that the particular filter is capable of removing.

FAQs

Q. What Are Some Ways to Know the Contaminants Level in The Well Water?

Direct use of well water from a private well is not recommended at all, and it may contain harmful contaminants. To know exactly what type of contaminants are present in the water, whether it is chemicals, bacteria, or simply high TDS level, you can use many water testing kits available in any of the stores.

Another way to get the exact presence of contaminants and their quantity is to just send the sample from your well water to any water testing company, and they will provide you the detailed report on the contaminants level.

After analyzing this report, you can decide on which water filter is best suited for this well water.

Q. Why You Shouldn’t Install a Well Water Filter Outside?

When it comes to the whole house filters that are designed to purify the well water, they are intended to be installed at the point of entry in the house. There are some filters that exist in the market which you can install outside, but with the majority of filters, you can’t keep them outside.

The reason being, filters are designed to work satisfactorily in the certain temperature and pressure range. When they are installed outside, the temperature doesn’t stay in this range. It drops significantly low in winter and reaches a very high level in summer. Filters don’t work as intended in these extremes.

You can always consult the manufacturer to see if it is possible to install the filter outside.

Q. Is It Safe to Drink Water Directly from A Whole House Filter?

It depends on what your whole house filter removes from the well water. A simple whole house filter will only deal with the bad taste and odor of the water, and it won’t remove any of the other contaminants. There is no guarantee on the purity of water from a whole house filter. So, if you want to use water directly from a whole house filter for drinking, then first get it checked at any lab for contaminant levels.

Q. How Much Does It Cost to Install a Best Whole House Filter?

If you want the simplest whole house water filter then the price can vary between $250 to $500. But we suggest that you always keep in mind the long-term use of a filter than the initial cost. Because it might cost you less now, but in the long run, it will require much more maintenance and frequent cartridge changes.

YouTube video

On the other hand, a filter that is costly and has a quality filter will not bother you so much in terms of maintenance. If you want a better filter, then you will need to keep your budget high.

Q. Are Whole House Water Filters Worth It?

If your daily water needs are fulfilled by well water, then definitely a whole house filter is worth it. The well water is going to have many contaminants like sediments, leached chemicals, rust, and disease-causing microorganisms.

A good whole house filter takes care of all the contaminants in the water, and it also removes the high level of TDS and improves the taste of water. In fact, it ensures your good health. Not only that, it also improves the lifetime of your water equipment by removing most of the hard minerals from the water.

Even if you live in a city and get filtered water from a municipality, then also it won’t hurt to have a simple whole house filter installed. It removes most of the contaminants along with the chlorine and chloramine from the water.
