Top on the list is this Express filtration system, the reason being its an efficient purifier with minimal water wastage.

This system can eliminate up to 98% of the contaminants present in your water in its purification process.

With the five stages purification process, the final product is pure water. The first stage works to remove the larger particles such as sand, dust, rust, and dirt.

The next two stages comprise granular activated carbon that helps the system remove the chemical components such as organic materials and chemicals like chlorine.

Reverse osmosis happens in the fourth stage, where the more difficult impurities such as lead are eliminated. The semi-permeable membrane allows only the water molecules through, resulting in purified water.

Finally, the final stage polishes your water to give it great an excellent taste and remove any foul odor in your water.

This system is fitted with a leakage detector to reduce water wastage, and an increase in the detector’s moisture content raises the alarm. This makes it possible to mitigate any leakage within the system.

It’s also fitted with a vital shut-off valve in case excess water from leakage is detected. Furthermore, the filters in this system are double sealed, which means they are preserved to give you maximum value.

This purifier can withstand a flow rate of up to 0.8 GPM. It allows the water to flow fast without being held in the system, which could overwhelm it, leading to leakages.

This system also comes with a 4-gallon tank which also aids in minimizing water wastage. Holding the water in the tank means that you get access to pure water when you need it, and in case of a break down the tank can hold the water as you do the repairs.

Filters that come with this system last up to 6 months. This means in a year, you get to flush the system when cleaning it twice; thus, minimal water loss during the replacement procedure.

PROS:

Buyers Guide

Consider the following factors when looking for the best purifier without water wastage.

1. Pure to Drain Ratio

This is the amount of water purified compared to the volume of water wasted during the purification procedure. Go for a purifier that has zero water wastage, or the ratio is minimal.

2. Purification Technology

Purifiers that use UV and UF purification technologies are known to waste zero water. However, if your TDS level is high, you will have to go for RO water purifiers or use the combined technologies.

RO water purifiers are also known to be efficient with an increased flow rate, and some also act as softeners.

If you buy a RO water purifier, check out for the pure to drain ratio and the allowance to have it fitted with a permeate pump. This way, you are guaranteed zero water wastage.

3. Certification

Go for a water purifier that is certified by reputable bodies. Consider the NSF/ANSI certification or the WQA. This way, you will have peace of mind knowing the purifier has met the quality obligations.

4. TDS Control Knob

If you choose to go for a RO water purifier, ensure it has a TDS control knob. When an RO water purifier dispenses water with a shallow TDS level, more water is wasted. The knob will allow you to increase the TDS level and thereby minimize the water wasted.

5. Allowance for Permeate Pump Modification

For zero water wastage when using a RO water purifier for your purification, check to see it has a permeate pump. If it doesn’t have one before you buy, ensure it can be modified to accommodate one.

This way, you are guaranteed you will have minimized the water wasted drastically.

6. Water Pressure

A high water pressure translates to a raised flow rate. Purifiers that can handle an increased flow rate mean reduced water and your plumbing system’s contact time. This way, contaminants that cause build-up and clogging with eventual leakage are not retained on the pipes.

7. Leakage Detector

Buying a purifier with a leakage detector will give you peace of mind knowing that any slight leakage in the filter will detect fast.

8. Ball Valve for the Tank

For purifiers that come with tanks, ensure that they either have a ball valve or an automatic shut-off valve. These stop overflow in the tanks once full. They allow you to mitigate the water wastage risk.

9. Space Available

When buying a water purifier, consider the space you have available to host the purifier. RO water purifiers are generally bulky and will need a bigger space.

10. Cost

Water purifiers that waste minimal water vary in cost. Depending on your clean water demand and space available, there is a purifier for every budget. You can even start with a filter pitcher as they cost less, waste less water, and you will still get quality water.

Frequently Asked Questions

1. Which RO purifier wastes less water?

RO purifiers that are fitted with permeate pumps waste less water. Also, those fitted with leakage detectors minimize the risk of water wastage.

2. What type of water filter leads to wastage of water?

The conventional RO that are not fitted with permeate pump wastes more water at the rate of 1:3. Meaning for every glass of filtered water dispenser, 3 glasses of rejected water are wasted.

Therefore when buying the RO filter, insist on the permeate pump modification.

3. Which water purifier has a low maintenance cost?

Water purifiers with several purification stages have minimal maintenance cost since the filters’ replacement is not regular.

4. Does water purifier wastewater?

Yes. A water purifier will sometimes wastewater if the installation is done purely and maintenance neglected. Lack of leakage detection also leads to purifiers wasting water.

5. How can I achieve zero water wastage?

Invest in a water filter that uses either UV or UF filtration technology. If you use RO water purifiers, ensure they are fitted with permeate pumps.

6. Which water purifiers last long?

With proper maintenance, most of the purifiers can last for a long time. Ensure you replace the filters and membranes on time for longevity.

7. Between RO and UV purifier, which one wastes more water?

The conventional RO purifiers waste more water compared to the UV purifiers. However, if TDS levels are high in your water, you need to invest in a combined purifier for maximum benefit.

Add a permeate pump to the RO purifier to minimize water wastage.

8. Do I need a storage tank to reduce water wastage?

A storage tank only serves to hold the filtered water to avoid running the purifier every time you need a glass of pure water. Water storage after purification is a critical aspect as it prevents water loss.

Conclusion

Water purifiers do a great job in ensuring your household is supplied with purified water. However, the purification process should be done in a way there is minimal to zero water wastage.

Zero water wastage can only be by having the right purifier for the process. Consider the purifiers listed above for highly filtered water and minimal water wastage.

Ensure timely maintenance of the purifiers. This way, you will have pure water all through, and still, during the purification process, less water is wasted.

Leakage in the purifiers, especially at the connector points, is a great contributor to water loss. Invest in a leakage detector even if your system doesn’t come with one; you can have the plumber install one.
