How To Choose The Best Waterdrop Filter For Your Needs

When choosing the best Waterdrop filter, considering some crucial aspects is important.

The followings are the top important things you want to consider before buying a Waterdrop filter.

What Type Of Filter Does It Has?

Waterdrop filters generally have three types of water filters: Reverse Osmosis, Ultrafiltration, and Carbon Block Filter.

Reverse Osmosis water filters are a great choice for use as drinking and cooking water.

In contrast, if you want to remove all colloidal particles, Ultrafiltration is a better choice.

A carbon block filter is a great choice for removing harmful organic compounds and impurities.

It also improves the taste, smell, and quality of the water.

What Is The Capacity Of The Filter?

The capacity of a water filter ranges from 400 gallons to 10000 GPD.

For household purposes, a 400 GPD rating is enough. They will filter around 40 gallons of water per day.

But if you want to use it for commercial purposes, I recommend using a 600-700 GPD rating water filter.

This type of water filter can filter 60 to 70 gallons of water daily.

What Is The Flow Rate Of The Filter?

The flow rate of a water filter can be anywhere from 0.8 to 2.5 GPM.

Does your household have high or low water contamination levels with more or less fouling components?

If the water has reduced harmful substances and minimal fouling odor, a faster flow rate is better to reduce the processing time and save energy.

On the other hand, when your main water source contains a higher level of harmful substances with too much bad smell, you want a water filter with a relatively slow flow rate.

The main advantage of a slower flow rate is its better interaction with contaminated water.

It traps and filters out the maximum harmful substances from the water. 

What Is The Water Pressure Of A Water Filter?

A water filter’s water pressure can be from 30 psi to 100 psi.

If your Waterdrop filter has an RO system, the water pressure should be around 40 to 60 PSI.

Generally, higher water pressure ensures more increased water flow.

Some come with a pressure limiting valve to control the pressure for filters that can’t withstand extreme pressure.

A water filter with reasonable water pressure is necessary to make the overall system efficiency and prevent unwanted energy wastage. It will also ensure a better filtration effect.

Can The Water Filter Remove Odor?

Water filters have an aeration system or an activated carbon filter to reduce various types of odor.

An aeration system appears more practical when the water has gas contaminants.

But if the water filter has bad physical substances that cause a foul smell, activated carbon filters are the best choice to get rid of them.

How Much Water Will Waste And Drain? 

Regardless of the Waterdrop filter you choose, they waste and drain a specific amount of water while filtering the water.

However, their wastage rate may vary from one to another.

It is mainly described in ratios, such as 1:4, 1:2, 1:1, and  2:1 water waste ratio. Avoid choosing any water filter with 1:4 water waste systems.

They waste a huge amount of water. A 1:1 and 2:1 water waste ratio is the best choice as they ensure minimal water waste because, during the process, one gallon of pure water is.

How Many Filtering Stage The Waterdrop Filter?

High-end water filters may have up to ten-stage water filtering systems. But most have 5 to 8 stages of water filtering system.

It is necessary to choose at least four stages of water filtering systems.

Experts recommend selecting seven stages of a water filtering system to ensure safe drinking water.

The water filtering stage a water filter has, the cleaner and safer will be the water.

It is especially important if your water source has higher contaminant and pollutant substances.

What Is The Price Of The Waterdrop Filter?

How much are you ready to pay to own a high-quality Waterdrop filter?

If the under-sink water filter has several stages of filtering system, it will cost anywhere from $150 to $500.

But water filters with reverse osmosis systems will cost around $200 to $500 depending on their filtration rate, type, and other things.

How Long Does The Waterdrop Filter Will Last?

The average lifespan of a regular water filter can be anywhere from 5 to 7 years.

The service life of a Waterdrop Filter varies depending on its type and how much water is processed daily.

Ultrafiltration Waterdrop filters have a service of three to seven years.

In contrast, reverse osmosis systems can last anywhere between 10 and 15 years.

However, you want to replace pre- and post-filters every six months to one year.

Carbon block water filters can last up to four years. But, experts recommended changing the filter within 18-24 months if you used it heavily regularly.

 Humidity, usage patterns, carbon quality, and plant type will affect the overall lifespan of the carbon block water filter.

Is The Waterdrop Filter Easy To Install?

Installing an under-sink water filter requires around two to four hours for an experienced plumber.

If you don’t have a higher level of plumbing knowledge, the installation duration might be longer.

Besides, you need all the essential tools for simple installation. Using the right equipment will make the installation task easier.
