A reverse osmosis (RO) system is a technology that purifies water, allowing you to drink pure clean water. It eliminates the bacteria, germs, and other contaminants in the water. The system works by shoving the water to pass through a semi-permeable membrane that filters out almost 99% of water contaminants.
Factors to Look for when Buying a Reverse Osmosis System
The market offers several brands of RO systems, each of which claims to provide the best performance. All RO systems in the market function in the same manner and have the same design and components. With these similarities, choosing which brand to purchase can be maddening. Following are factors to look for when buying an RO system.
Choose a reverse osmosis system with filters that are easy to replace.
The filters should have at least 6- to 12-month round change schedule. The filter should be reasonably priced. Filter sizes are standard, so you can purchase it from any water filter store, just make sure they are of excellent quality.
Consider the price. Do not purchase a system that is less than $200.
These systems are of poor quality and will only give you problems and have a shorter lifespan. Low-priced RO systems are mass produced and made of substandard parts so they will eventually leak and crack easily under pressure. Although the price is a big consideration when purchasing an RO system, an expensive system is not a guarantee that it will perform better. Some high-priced systems are of poor quality.
Examine the components.
Choose a system that is made of superb quality components, particularly certified made in the U.S. Look for good craftsmanship, such as clean neat line connections and the system fits perfectly on a sturdy frame. Excellent quality materials and craftsmanship are the secrets of an effective and long-lasting RO water drinking filter system.
Select a 5-stage reverse osmosis system.
A system with fewer stages like three or four stages is less reliable and stable. It requires frequent filter changes (every 4 to 5 months), giving you more problems. A good-quality 5-stage reverse system has filters that last up to 9 to 12 months. It also provides better-quality and better-tasting water. A 5-stage system saves you time and money in the end.
Choose a system that has three pre-filters, two carbon blocks and a sediment filter.
The pre-filter filters the sand, dirt, deposits and other sediments before pushing the water into the RO membrane. The carbon filter is the next stage where chlorine, taste and odor pollutants are filtered and protects the early wear of the membrane due to the chlorine. Most of the 4-stage RO systems have only one carbon filter before the semi-permeable membrane. The other carbon filter is placed after the membrane, thus the membrane does not get the protection it requires.
Select a solid “carbon block” filter.
There are two types of carbon filters, namely: carbon block and granular activated carbon (GAC) filters. The carbon block filters do not leak fines and last longer. The GAC filters are inclined to leak carbon powder that block the RO system and wear out easily exposing the membrane to chlorine.
Purchase a reverse osmosis system with one, not two sediment pre-filters.
Sediment filters are cheaper than carbon filters. Some manufacturers use a sediment filter instead of a second carbon and this compromises the quality of your water and the lifespan of the system membrane.
Verify the reliability of the supplier.
Always check the integrity and trustworthiness of the supplier, particularly when purchasing an RO system online. The supplier should have a superb technical and parts support and a 24-hour and accommodating customer service. Read reviews of past customers to check the supplier’s reliability and integrity.
Do not be misled with claims of long warranties, such as 5 to 10 years warranty.
These are usually restricted, where you need to provide proof that the system was properly maintained to be covered under the said warranty period. It may also be that the warranty does not cover your specific components or problem. Read the fine print of the warranty to avoid confusion.
Get yourself armed with the above tips when buying a reverse osmosis system to ensure you get the value of your money.
