Ro Water Purifier Manufacturer : The Ultimate FAQ Guide

Purified water is indeed very important in our everyday lives.

Therefore, commencing a business that is related to this kind of machine is a wise move.

Though, we understand that it is not easy to find a manufacturer that will be a good partner for you.

Nothing to worry as we are here to help you answer all of your questions in order to proceed.



What is the best location for manufacturing the RO water purifier?

For your Ro Water Purifier Brand, Chinese manufacturers are the best choice.

In recent years, China’s economy has grown to become one of the largest in the world.

Since the government allowed international trade and brought in the global market, several changes have occurred in the country.

China has grown significantly as a manufacturing and purchasing powerhouse in recent years.

There is no denying China’s prominence as a manufacturing powerhouse.

There are a variety of factors that contribute to this, including expertise, ability, credibility, and ease of doing business.

We are proud to inform you that Ningbo Longbank Resources possesses all of these characteristics.

The following is an overview video of our company:


To be marketed to the general public, must the Ro Water Purifier machine meet certain standards?

Before importing or exporting our appliances, including Ro Water Purifier machines, we ensure they are certified.

If customs officials doubt the safety of a product, they may seize it until the China product certification has been presented.

In order to ensure the quality of products, certifications are introduced.

In addition to 3C, CE, RoHS, UL, ETL, CB, SAA, GS certification, nearly every kitchen appliance certification is available.


How does  Ro Water Purifier work?

By using pressure to force water molecules through a semipermeable membrane, reverse osmosis (RO) removes contaminants from water.

The contaminants are filtered out and flushed away during this process, leaving clean, tasty drinking water behind.

Please see this table for the working principle.


Stage 1, 5 Micron Sediment Filter 20 inch Sediment filters can efficiently eliminate suspending sand, rust, and other particles bigger than 5 micron.
Stage 2, Activated Carbon Filter 20 inch GAC Filter can efficiently absorb the free chlorine, heavy metals, organic chemicals and bad smell.
Stage 3, CTO Filter 20 inch CTO Filter can efficiently remove the free chlorine, heavy metals, organic chemicals and bad smell.
Stage 4, Reverse Osmosis Membrane A thin film composite 4 high quality membranes.

Can process 400/600/800 gallons of water per day.

It removes hard water contaminants:lead, cooper, barium, chromium, mercury, sodium,cadmium, fluoride, nitrite, nitrate, and


Stage 5, Post Carbon filter Removes objectionable tastes and odors to enhance taste.


Please check out this video to have a better understanding:


What is the advantage of  Ro Water Purifier?

Among the pollutants that can be removed from water by reverse osmosis systems are lead, pesticides, fluoride, pharmaceuticals, arsenic, and many more. 

In addition to removing chlorine, an RO system can also improve the taste, odor, and appearance of your water with a carbon filter.

Living in a highly polluted world has the unfortunate side effect of increasing your risk of contracting deadly diseases such as cholera, E. 

With an RO water purifier, you can reduce your risk of getting sick by filtering out 99% of bacteria from your water.

With that being said, this machine is very important to all of us.

Why is it important to use Design for Testability when manufacturing RO Water Purifiers?

Developing products in a testable manner (also known as Design for Test, or DFT) makes it easier for testers to test them. 

There are a number of test points, parametric measurement devices, self-test diagnostics, test modes, and scan design examples that are typical of testing.
Testability features are added to hardware designs through IC design techniques. 

The addition of new features simplifies the development and application of manufacturing tests for designed hardware.

While performing quality control and inspections, DFT is taken into account. 

Coating system durability is determined by the thickness of each coating layer and the total DFT for the entire system.

Is it possible for manufacturers to release different versions of Ro Water Purifier?

Yes, without a doubt! We have a lot of options to choose from, it is true.

Whether you want a standard design or a customized one, we have it all.

You can check out some of these best sellers:

What is the minimum order quantity for Ro Water Purifiers?

There is usually a minimum order quantity for a product or service that a business will sell to a customer at one time.

MOQs are typically used by manufacturers or suppliers in the context of production runs, but they can also be used by merchants.

Having said that, we always set our MOQs to be reachable by our clients.
For this specific appliance, such as Ro Water Purifiers. There is a minimum order quantity of 1000 to 1500 pieces.

Even so, we still need to consider the type since there are different MOQs for different appliances and versions.

This is determined by their pricing, the materials they use, and other factors.


What is the power consumption of an RO water purifier?

Due to the fact that people use 2 liters of water every day, reverse osmosis water purifiers consume 0.03 kW of electricity per day. 

To consume 1 kW of electricity, the water purifier must filter 33.33 liters of fresh water. 

So basically, it depends on how the water is consumed per day.

But for Watts, most of the models we manufactured only consume 500W

How sustainable is that?


Does the manufacturer design Ro Water Purifier with Safety features?

Yes, of course! It is our priority to build them with safety features. There is no danger in using them.

You should test your local water quality before purchasing a water purifier to determine which one is best for you.

 You can choose between RO and UV water purifiers based on the quality of the water in your area. Additionally, you should check whether the water purifier is certified.


How do manufacturers of RO water purifiers assist small businesses?

According to estimates, small businesses generate 43.5% of the country’s GDP and create two-thirds of new jobs.

Additionally, small businesses keep the economy going by contributing to innovation. 

Small businesses produce 16 times more patents per employee than large patenting companies.

It is not only small businesses that contribute to their communities, but they are also passionate about what they do.

As important as helping small businesses grow is our support for them.

In addition to benefiting from small businesses, customers can also benefit from them.

Having said that, we are looking forward to working with you and coordinating.


For manufacturers, what are the benefits of wholesalers?

Wholesalers play a vital role in improving the efficiency of transportation for manufacturers. 

After bulk shipments from suppliers are received by wholesalers, many retailers receive goods directly from them. 

The wholesalers are responsible for breaking down large quantities. 

Manufacturers are not concerned about small packaging and small shipments, but with quality and efficiency.

Why does the manufacturer make sure the Ro Water Purifier machine works with different types of electrical sources?

In order to ensure that there will be no damage, fires, or other problems with our products, we carefully test them.

All Ro Water Purifiers  have universal compatibility

In order to ensure compliance with standard socket types, it is necessary to look at the region/country.

An adapter can also be used.

Plugin adapters do not typically support grounding, however. 

There is a difference between the operation of ground plugs and grounded circuits. 


Is there a standard turn around time for Ro Water Purifier orders?

The industry places a great deal of emphasis on turnaround time (TAT).

Besides improving the efficiency of the industry and laboratories, 

Furthermore, it strengthens the relationship between industry authorities and their customers.

Any business organization’s delivery depends on the number of orders it receives. 

There is a tendency for it to take longer when the number is higher.
In most cases, it takes between 30 and 45 days.

The production of pieces with quantities of 1 – 100 can take up to 15 days.

Higher pieces are negotiable and can be discussed. A delivery of 100 – 1000 pieces takes 30 days.

It doesn’t matter what the season is, we guarantee a 100% On-Time Delivery Rate.

What is the most affordable shipping method in China?

Large, heavy shipments are often more economical to ship by ocean.

In contrast, as shipment sizes decrease, the margin between air and ocean prices also decreases.

The first step toward a more sustainable future is to reduce transportation costs.

Please note that air shipping is not recommended for large volumes of orders due to expenses. 

In the event that you are just taking samples, we can offer it to you.

The option of land shipping is also available.

Express Delivery is also available, but it comes at an additional cost.


Is there a customs fee when ordering from an international package?

Either the seller or buyer of a shipment is responsible for paying customs duties, fees, and taxes. 

Generally, the party responsible for payment is pre-arranged between the shipper and receiver. 

Most of the time, the buyer is responsible for paying. 

We cordially invite you to contact us via email for further details.

Is Ro Water Purifier manufactured in China in accordance with ISO standards?

That’s right, of course! An organization receives this certificate when a certification body certifies that its quality management system meets ISO 9001 standards. Often, Chinese suppliers provide it as one of their most common documents.
Due to the fact that we manufacture all over the world, we are responsible for adhering to these types of organizations.

It is not taken for granted that this agreement exists.

The China ISO Member body is the Standardization Administration of China.

When dealing with Chinese companies, ISO 9001 certificates are commonly seen. A quality management system inspection and certification indicates that the company has established a quality management system.

Additionally, we were in compliance with other Standard Certifications we needed to maintain in order to remain in business.

To ensure quality, more than one person is needed. 

We make sure that all of the professionals in this field in our team are involved whenever we work on this issue.

Moreover, we always make sure our staff is well informed about the improvements we need to make.

Additionally, we offer customization of packaging and graphics printed on your machine.

It would be helpful if you could let us know what type and design you want.

Direct orders from manufacturers are more efficient, so why should I do that?

In direct deals, manufacturers usually offer better shipping options, greater control over transit, customs handling, and quality oversight. 

In addition, buying directly from the manufacturer ensures a higher level of authenticity.

By working directly with retailers, manufacturers can offer wholesale prices, giving them a competitive advantage.


When it comes to after-sales service, how do Ro Water Purifier manufacturers fare?

We offer the same warranty on all of our products.

After purchasing a Ro Water Purifier, you can use the warranty within one to two years.

Factory defects will be covered, but customer-caused malfunctions will not.

A professional maintenance team should provide services to clients.

We also offer on-site installation services.

Furthermore, spare parts are free of charge.

How does OEM work in the manufacturing of RO water purifiers?

Making components for other companies is known as original equipment manufacturing (OEM).

A value-added reseller (VAR) then sells the end-product under its own brand. 

OEMs market to other manufacturers’ retailers while VARs target the general public

Utilizing the supplier’s existing category expertise, supply chain, etc. The factory develops a new product from a buyer’s design.


In order to evaluate the effectiveness of your product, would it be possible to obtain samples?

It is a great way to let clients know what your products are like and to test their quality by providing samples.

Providing product samples is the best way for us to help clients better understand what we offer.

As well as introducing our product or Ro Water Purifiers to new clients unfamiliar with our brand.

Encourage loyalty among existing clients by developing relationships with them.

We offer a wide range of products.

You are welcome to request samples if you wish. 

Sample charges and shipping costs will, however, be the buyer’s responsibility.

It is possible to get a credit back on your account if you decide to place an order.

Samples can only be delivered within 1 to 7 business days in order to reach your preferred address.

Are Chinese manufacturers able to sell replicas of Ro Water Purifiers?

In order to create the best products, we use the best raw materials and manufacture them according to the highest standards.

Our official website and email address are the best places to make your purchases if you want to protect yourself from online fraudsters.
Upon request, we can provide you with our quality certificates so that you can verify the authenticity of our products.

Our company operates with honesty and integrity since we believe that what goes around comes around.

A wide range of clients from around the world have trusted us with their creations.

The importance of this cannot be overstated.
