1) Most households use tap water as direct drinking water. Even if the tap water has been treated and the water quality reaches drinking standards, this does not guarantee long-term drinking safety. If your home has aged pipes that contain lead and iron, the quality of your drinking water will be affected. This eventually leads to problems such as rusty smell in the water, high blood pressure, and kidney disease.

2) Many households face hard water issues due to local water quality issues or the use of well water as a source of drinking water. Long-term drinking of hard water can lead to hair loss, gastrointestinal upset, and dry skin, among other problems. Hard water can also lead to the accumulation of scale, affecting the service life of household appliances.

3) Some remote areas face challenges accessing drinking water, and bottled water is too expensive. Residents can only obtain drinking and domestic water through lakes, rivers, and seawater. However, these incoming water may contain harmful substances such as lead, viruses, organic matter, soluble salts, odors, and bacteria. So installing a reverse osmosis water filter/ultrafiltration filter is crucial to ensure a healthy water supply.

If you are struggling with the abovementioned problems, NEWater recommends investing in a reverse osmosis filtration system to improve water quality. Before purchasing a reverse osmosis system, you can use a TDS water test pen to evaluate your current raw water quality.

➢Reverse Osmosis System Advantages

Multi-level filtering

The reverse osmosis system uses multi-stage filtration, such as 3-stage, 4-stage, 5-stage, and 6-stage filtration, to ensure a thorough purification process. The benefit is to ultimately provide water that meets different levels of high-quality standards.

Effectively remove contaminants

The reverse osmosis system effectively removes almost all impurities in raw water, including heavy metals and hardness, ensuring that the water you drink is cleaner and safer. Learn how reverse osmosis systems work.

Improve sense of taste and smell

The pretreatment system in a reverse osmosis system includes an activated carbon filter and a water softener, which can filter out bad odor pollutants and calcium and magnesium ions.

➢How to Choose the Best Reverse Osmosis System? What Factors Do I Need to Consider?

Choosing the right reverse osmosis system for your home involves considering a few important factors. Here are six steps to guide you in selecting the best reverse osmosis system that truly fits your needs:

1. Budget

$1000-2000 Suitable for beginner users who have never used a reverse osmosis system and are looking for a cost-effective option.
$2500-$3500 It is suitable for users who have a certain understanding of the product and want to update their pure water equipment. Look for a system that is durable and requires low maintenance.
$4000-$5000+ Suitable for users with high product quality requirements and good economic conditions. There are requirements for the multi-function of the system.

2. Parameters

The purified water flow rate is related to the total purified water volume. RO water purifiers cannot look at the purified water flow rate alone. For example, a water purifier has a rated total water purification capacity of 4000L, a purification water flow rate of 5L/h, and a filter element life of 800 hours.

If the total rated water purification capacity of another water purifier remains unchanged at 4000L, and the purified water flow rate is 10L/h, its service life will only be 400 hours. NEWater recommends that when choosing a water purifier, you carefully compare the purified water flow rate and the rated total purified water volume to choose a cost-effective water purifier.

RO System Parameters

It is worth noting that the wastewater produced during the filtration process can also be called “concentrated water” and can also be used for activities such as watering plants or flushing toilets.

3. Filter Element

The correct choice of filter element determines the service life of your water purifier. Here are a few key considerations to consider when choosing a filter.

  • Choose reverse osmosis membranes from well-known brands to ensure quality, such as Dow, Toray, GE, Shihan, Haide, etc.
  • Choose an RO system with a larger rated water purification capacity for better durability and quality.
  • Check your system for additional features such as rolling film technology, multi-film blades, and automatic flushing to ensure protection of equipment life and performance.
  • Replace the filter element when it reaches about 80% of its ideal life.

The cost and price of filter elements are mainly divided into two levels, one is the auxiliary filter element (multi-stage universal filter element, composite filter element) and the main filter element (RO filter element, ultrafiltration element). The price of one liter of water = the price of various filter elements plus cycle ÷ rated water purification capacity.

Another influencing factor is the number of filtering stages. Generally speaking, the more filtering stages, the better. It does not mean that the higher the price of the filter element, the better the quality and the longer the life. You can choose the most cost-effective filter brand based on specific models and performance.

4. Function Configuration

The functional configuration of the reverse osmosis system mainly includes additional functions and hardware configuration. The hardware configuration is a closed design plus an integrated water circuit board. Additional functions are mainly basic functions such as convenient element replacement and filter element reminder. Others include APP intelligent control, zero stale water, intelligent auxiliary heating, screen display faucet, etc.

5. Classification of Water Purifiers

Understand the general classification of household water purifiers to determine the type that suits your needs.

Frequently Asked Questions (FAQs):

1. How does an RO Water Filtration System Work?

A Reverse Osmosis System essentially incorporates additional layers of protection between water inlets and outlets. These layers, in the form of filters and membranes, permit the passage of clean water while retaining impurities such as solid particles and salts.

The best RO systems may also include features like UV light to eliminate microorganisms or post-taste filters for refreshing water taste.

2. Is Distilled Water better than RO Water?

While distillers and RO filters share a similar function, they operate differently. The best RO systems utilize water pressure and a membrane to filter impurities, providing instant clean water. In contrast, distillers boil water, capture the steam, and condense it back into liquid form.

Both methods are effective, with superiority depending on the impurities you’re dealing with and the intended application, be it commercial water purification or water filtration at home.

3. How long does an RO water filtration system last?

The lifespan of RO systems varies, typically lasting between 2-5 years and potentially indefinitely with proper maintenance. Some of the best reverse osmosis systems from reputable companies, such as NEWater, come with a 2-year warranty, offering insights into their expected duration.

4. Does a Reverse Osmosis (RO) System remove minerals?

Technically, yes. However, this is by design, with the primary goal being to provide clean water. While minerals are removed, it’s important to note that the absence of these minerals in water is far less harmful than consuming water contaminated with heavy metals. When considering clean and safe-to-drink water, RO systems remain among the best options available.

5. Is RO System maintenance cost high?

Most RO systems necessitate an annual replacement of pre-filters and post-filters, while the membrane lasts an average of 2-5 years, contingent on quality, water quality, and usage. Maintenance costs are usually higher for commercial water purification and lower for water filtration at home.

Even for the best RO systems, maintenance expenses pale in comparison to the potential costs associated with healthcare in the event of contracting a waterborne disease, making it a prudent investment in all respects.
