Whole house water filters are very handy as the offer a comprehensive solution to all the water related issues at hand. The whole house water filters are very popular because they deliver high quality and safe water and are very effective too. Also, these systems are eco-friendly and they don’t produce any harmful substance or chemicals in the water.
From cleaning to bathing and from cooking to drinking, water is the most important part of everyone’s daily routine. Without safe and clean water everything can go wrong and can cause threat to a healthy lifestyle.
Fortunately, because of the advanced technology things are getting better and advanced methods are being used to make the water pure and safe for daily use. A whole house water filter is a purification and treatment unit that that filters and cleanses the water and makes sure that the water is not contaminated.
Whole House Water Filter Buying Guide:
A good quality whole house water filter is certainly the best investment for anyone who is troubled with the smell of chlorine or other metal in the water. However, there are many options available as there are many companies that design whole house water filter.
In such a situation, it gets difficult to choose one. So, if you’re going to invest in a whole house water filter, consider these factors before you do it:
The first thing to find out is the quality of water at your place. This will allow you to get a water filter of the exact type that is suitable for removing the contaminations in your water. Is your water sourced from city water or well? Do you have access to the quality report of the water you get? If you aren’t sure, you can send the water to a lab and get the lab report from there. Also, there are test kits available that give you a little bit idea of your water quality. If you’re receiving municipal or city water, you’re lucky because you’ll get the quality report for free.
However, municipal tap water contains haloacetic acids, trihalomethanes, and fluorides that can pose serious risk to the health. In some cases, water is polluted with chemicals such as herbicides, fertilizers, pesticides, and harmful microorganisms. There is a chance that the water may be contaminated with lead if you’re using old pipes. Following are some common types of contaminants in water:
- Chemical contaminants can be man-made or naturally occurring. Examples include pesticides, salts, metals, bleach, toxins produced by animal drugs, bacteria or humans. The metals include ferrous and ferric those are two forms of iron.
- Physical contaminants include materials or sediments suspended in rivers, lakes and streams from soil erosion.
- Radiological contaminants include uranium, cesium, and plutonium.
- Biological contaminants are the micro-organisms present in water and that include parasites, bacteria, protozoan, and viruses.
The next important step is to determine your household requirements. Some household filters are based on the maximum flow rate through your place. For example, at a particular time in the day there will be a maximum flow rate because there will be so many activities going on at once.
There must be someone bathing, dishwasher running, using washing machine, toilet flushing and thus the flow rate will be high at that time. The number of bathrooms in a household also helps to determine the flow rate.
Another important thing to consider is the number of people in your house. The flow rate will also depend on this as the greater the number of people, the higher the flow rate. Knowing the number of people can give you an idea of the household water usage. Some whole house water filters size is based on the average flow rate or total water used by a household per day.
Flow rate and microns:
The flow rate, as mentioned above, is the measure of the amount of water that is used or spent in the household. It is measured in gallons/minute and to buy a water filter, you must first determine the flow rate. For example, toilets and dishwashers will have a flow rate of around 3 to 5 gpm while a showerhead will have 2.5 to 5 gpm.
A bathroom faucet will have a flowrate of 1.5 gpm while a kitchen faucet will have a gpm of around 2.2 gpm. Now depending upon the number of dispensers such as hot water heaters, showers, toilet, and dishwashers, you can take out a rough estimate of the total gallons per minute. You must also consider the family members of the household because this also affects the flow rate.
Most of the standard flow rate requirements of small to large households are ranged between 15 to 40 gpm. For the total flow rate you’ll have to add the individual flow rates and then get an estimate.
If you want, you can also consult a professional for help. Another thing to be noted is the micron, which is the unit for measuring the effectiveness of a water filter. A smaller micron rating indicates thorough filtration where 1 micron is a thousandth of a millimeter.
For example, a water filter with a micron rating of 50 will be able to remove rust, sand, and silt. A micron rating of 50 won’t be able to remove smaller particles such as chemicals, lead, fluoride and most of the pathogens. There are micron ratings of 25, 10, 5 and even 1 but there is one problem with a small microns rating. The smaller the microns rating, the lesser the water flow.
Size of the water filter:
The larger the size of the water filter, the greater the flow rate and the pressure. For most of the homes, the ideal size is 4.5’’ X 20’’ but larger homes will need larger filters of around 25 gpm flow rate. Port size also plays an important role here and the ideal port size is 1’’ if you want to avoid pressure drops.
The port size is the connection point diameter and it helps in carrying enough water through it so that the pressure drop becomes virtually non-existent.
It is a good thing if your water filter is certified by the NSF (National Sanitation Foundation). Certain verifications and certifications such as the WQA (Water Quality Association) seal on the whole house filter indicate the high quality and standard compliance.
These are the most prestigious organizations in the US and certifications from these companies are necessary. However, even if your device is certified, it doesn’t mean that it is completely error free. Also, if your water filter isn’t certified, it doesn’t mean that it is of poor quality.
This is because certification from these organizations is very costly which most of the small companies aren’t able to obtain.
No matter what the size of the water filter is, you must make sure that it is certified and approved from the concerned authorities. Such whole house water filters are not only compliant to the protection and safety rules by the authorities, but also solve all the filtration needs.
Types of water filters:
Choosing the type of water filter is also very necessary as there are many different types available. This must be done after you’ve determined the quality of water and identified the types of contaminants in the water.
The chemicals responsible for the unpleasant taste and smell of the water are chlorine, sediment, and other chemical substances. A water filter that is specialized to remove these materials will remove magnesium, iron, and other heavy metals from the water too.
A reverse osmosis system makes water 100% drinkable as it removes all the harmful substances from it. However, you must talk to a professional so that you’re guided in the right direction regarding the type of filter you need for your house.
If your main water line is maintained by municipal service, you’ll have to remove chlorine, sediments, chemicals, and minerals from it. If your main water line is sourced by a well, then you’ll need to consider removing iron, minerals, sediments, and hardness from the water.
When buying a whole house water filter you must not only consider the cost of buying the system, but also the maintenance and replacement costs. A filter with a higher capacity will be more expensive but it will last for long.
To buy a whole house water filter, you don’t need to sell your kidney but don’t go for the cheapest one either. For example, if your water supply is already soft, you won’t need an additional feature in your water filter and you can go for an affordable one that can just remove the harmful substances.
Lifespan of the water filter:
A whole house water filter is very hard to install, and it takes a lot of time and plumbing skills as compared to just using a countertop filter. There are many other things included in the maintenance such as replacing the cartridge which is another difficult thing.
For this reason, you must go for a water filter that doesn’t require maintenance very week or few days. This is because, maintenance of a water filter will involve turning on and off of the water supply that can trouble the family members. There are filters that are effective for even 10 years and you can choose them if you feel frequent maintenance is not your thing.
As compared to average filter systems, the whole house units are much larger and thus you’ll have to arrange ample space for it. If you have enough space at your home, you’ll be able to install it easily there.
Manufacturer and seller credibility:
There are many manufacturers and best sellers that provide free of cost installation, shipping, and other services. Always go for the sellers and manufacturers that are credible and have lots of positive reviews. Also, it is mandatory to get the installation done by the manufacturer and make sure they get it done from a certified and professional plumber.
Also, check the list of the contaminants that a water filter can remove. Look for free services and warranty too so that you don’t have trouble with maintenance later. FDA approved cartridges are very efficient but not all the manufacturers can provide it.
How We Picked:
We have picked the best whole house water filters so that our readers get to choose from a list of the bests. The performance and effectiveness of the water filters vary according to the type of the filter. Most of the water filter manufacturers publish the lab test reports on their websites and we checked them from there.
Some of the water filters didn’t have lab test reports and that’s the reason we requested from the company by calling them. We analyzed the report thoroughly and then picked the best water softeners. All the water filters listed here are tested by a certified third party lab.
How We Tested:
A lab test report lists the contaminants that the filter is able to remove. A water filter is considered of good quality if it’s able to remove most of the contaminants from the water. We tested the whole house water filters and compared them according to the number of water pollutants they were able to remove.
We also considered the water flow to determine the performance of a water filter. The third party lab tests were very helpful in determining the performance of a water filter. Some water filters are able to remove more contaminants than the others and that is how we decided the position of them on our list.
For example, one water filter might be able to remove 50% of a contaminant while other may be able to remove 90% of it. Following is a list of the 10 best whole house water filters we have picked:
