Best Reverse Osmosis System consumer reports Ultimate Buying Guide
Things to consider before buying
Filters
The filters are what will keep your tap water free of contamination.
We advise you to buy a sediment pre-filter and carbon post-filter system.
Keep in mind that some pre-filters will need replacement regularly to make sure the filtered water remains contaminant-free.
If you’re planning on drinking manufactured pure water, consider buying a reverse osmosis water filter with a remineralization option.
It puts back some miners that are removed during the filtration process.
Water Dirt
If you have well hard water, you should purchase a RO system with a filter to remove iron and hydrogen sulfide.
The style of reverse osmosis systems also depends on how dirty your hard water is.
It’s recommended that you purchase a membrane with a higher number of square feet if your water contains lots of dirt.
If you’re purchasing a system to use for camping, buy a lightweight and mobile unit.
Slipstream filters are more compact, but they do not last as long.
Filter Longevity
The filter’s longevity depends on the type of system you purchase.
If you have a tank-style unit, it will need a replacement filter regularly.
In this case, it’s best to purchase a system with an indicator light, and it will warn you when it needs a replacement filter.
It isn’t as crucial for a portable system because it doesn’t have a large tank to clean.
Make sure you know how often the filter needs replacement if you plan on purchasing a system with this feature.
Microns
The smaller the micron rating, the better.
Whole House Reverse Osmosis is an effective way to filter out contaminants, but it can’t remove microbial cysts like giardia and cryptosporidium.
Always choose a RO system with at least a .5 micron filter to remove cysts.
Consumption
Before buying a system, make sure about consumer reports and how much clean water your family needs from reverse osmosis.
If you have a large family, consider purchasing a system with a large tank.
If you live in an area where the tap water supply isn’t safe to drink, make sure you purchase a system with a dedicated faucet.
It allows you to access the pure water when you need it without disturbing the tank.
Water Flow
The filtered water flow is measured in gallons per minute.
Ensure you know how much your family needs before buying a system with this feature.
Some people prefer a high water flow, but it’s better to buy a system with a lower rate.
It can constantly refill a portable tank. If the water flow is too high, the filter may work too fast and the water will go through unfiltered.
Ease-of-use
If you travel often, it’s essential to purchase a system that is easy to transport.
A portable reverse osmosis unit is lightweight and comes with carrying handles.
The portable tank will be small enough for your car’s or compact storage areas.
If your family spends more time outdoors, this type of system might be the best option.
FAQs
Why should you use reverse osmosis?
Reverse Osmosis (RO) is a water purification process that uses pressure to force water through a semi-permeable membrane, which removes impurities from the water.
The RO system has been used for many years by commercial and home users.
The main reason why people are turning to RO systems is that they are much more efficient than traditional methods of drinking water treatment.
RO systems can treat up to 90% of the total water volume. This means that if you have a large amount of water flowing into your house daily, you won’t need to install multiple units to get enough clean water.
Another advantage of using an RO system over other filtration systems is that it doesn’t require chemicals to work effectively.
In fact, most of the time, there isn’t even a filter involved. You connect the pipes, turn on, and let the pure water flow.
Is Reverse Osmosis Water Better For You?
The reverse osmosis process removes most contaminants and chemicals from the water.
That makes it a great way to get uncontaminated drinking water.
There are some minerals that the process leaves behind which may make the clean water taste better.
RO system can remove up to 98% of these chemicals.
= Arsenic, Bacteria, Chlorine, Lead, Mercury, Nitrates
Some minerals are removed during this filtration process like:
= Calcium, Magnesium, Potassium
Each of these minerals is necessary for optimal health.
If you purchase a system with a demineralization option, some minerals add back into the water.
How to clean a whole house water filter?
If you have a whole house water filter, it will need regular cleaning.
You can buy a specific cleaning solution from your local hardware store that won’t damage the filter.
You may purchase a black band that fits your faucet for cleaning the filter with water pressure.
Once you’ve finished, turn on the faucet to help rinse away any remaining solution.
When should I use ROS?
RO is the best system to remove contaminants from the water. It includes heavy metals, bacteria, and chemicals.
We can also use it to make saltwater drinkable.
Suppose you live in an area where the water isn’t safe to drink. In that case, it’s best to get a reverse osmosis system that is advised in various consumer reports.
Which membrane should I use?
There are four types of membranes available for home reverse osmosis units.
Each one has different benefits and disadvantages. The following are the most common types of membranes:
– Thin Film Composite
– CTA (Cellulose Triacetate)
– Polyamide
– RO Membrane
The most popular membrane is the thin film composite.
Before purchasing a reverse osmosis system, review the benefits of each type of membrane.
It will help you find the best option for your household needs.
Conclusion
Reverse osmosis is a great way to get safe drinking water.
It’s essential to do research before purchasing the best reverse osmosis system as per consumer reports, so you know which option is best for your family.
Each unit has different features, but the most important ones are the size of the tank and the type of membrane used.
Make sure you understand your household needs before investing in any water system.
