5 Best Commercial Water Filters

If you want a successful business and a healthy workforce, you need the best commercial water filters. But given there are so many choices, what’s the right filter for you?

In this article, we created a list of the best commercial water filters considering key factors like production rate and filtering capability. In this way, you can pick exactly the right commercial water filter for your situation. So let’s get right to it!

In A Rush? Here are our Top Picks

Our Criteria

The market is flooded with a wide range of commercial water filters, so sometimes picking the right one can be confusing.

Here are some of the important factors that we monitored closely before recommending the best commercial water filters. 

Production (GPD)

Water filters are rated depending upon the amount of clean and filtered water they can produce per day. This is commonly referred to as Gallons Per Day (GPD).

The production rate is measured under various conditions. You can take a look at the entire measuring process here.

While a 50 GPD water purifier works well for residential use, commercially used water filters should have a GPD of more than 300 GDP or more for optimal results.

Filter Life 

The lifespan of a commercial water filter depends on the type of filter, the water usage, and the level of contamination. 

The average lifespan of a water filter is between three to four months. Some brands even offer a service life of up to a year or two.

Flow Rate

Flow rate is the amount of water that comes out of the faucet or the water outlet. It is measured in gallons per minute(GPM).

As a frame of reference, a residential complex with 9-10 residents and 4-5 bathrooms would need approximately 20 GPM as per these experiments. Depending on how big your establishment is, you might need an even higher GPM.

Our best pick has a GPM value of 35.

Water Pressure

RO filters and UV filters both make use of high water pressure. If your establishment does not have a consistent water supply, then you should not buy RO filters without a booster pump. 

Choosing a carbon-activated water filter will also solve the problem of low water pressure.

If your water supply is not only low but also high on TDS, then you have to get a RO filter. However, if you have a steady water supply, you can choose either UV or RO filter.

This model is a 5-stage filter system that comprises high-capacity filters which not only improve the water quality but enhance the life of the overall system. The first stage removes dust particles and rust using a polypropylene sediment filter.

The second and third stage filters use activated carbon filtering to remove chlorine, foul taste, odor, and cloudiness from your drinking water. The Volatile Organic Compounds are also removed in this stage.

The reverse osmosis membrane filter at the fourth stage removes up to 99% of the dissolved solids from your water. The pressure in this stage is so high that it can get rid of contaminants like arsenic, lead, bacteria, and viruses.

The contaminants that are stubborn enough to remain in the water supply after 4 stages of filtration, will find their way out in the 5th stage of the filtration process using its advanced coconut shell refining carbon. The residual taste from sitting in the filter for so long is also removed in this stage.

What we like:

  • Long-lasting filters with a 2-year warranty
  • The remineralization in the last stage enriches the water with important minerals and balance the pH of the water
  • Bigger output results in drawing more water in a shorter amount of time as compared to other brand commercial filters.
  • Filters are WQA(Water Quality Association) certified 

What we don’t like:

  • No booster pump. If you have low water pressure, you might have to invest in an additional permeate pump.

Best Suited For:

This model is good for organizations with good water pressure since it does not have a booster pump. It is perfect for providing safe drinking water to schools, offices, restaurants, and hotels.

Express Water Commercial RO Water Filtration System: Standard Water Filter

No products found.

If you own a car wash or hotel and really go through a lot of water every day, then you might want to go for something like the Express Water Commercial Filter. Its 2000 GDP is amongst the highest you can find.

Of course if you own a small restaurant, something like the WECO HydroSense filter is MORE than enough.

The Express water filtration system is a stainless steel construction that is sturdy and reliable. This model is equipped with a sediment filter at every entry point. This means that dust particles and rust can’t enter your water supply from any entry point.

The polypropylene microfibers in the filter can capture particles of 5 microns and above. It is not as good as the 1-micron water filters but if your water supply does not have super fine particles, you are good to go with a 5-micron water filter.

Other features are quite standard but one thing that makes it different is its compact design. It takes up less space than other commercial water filters and is comparatively light in weight. 

The installation process is easy and can be done on your own using basic home tools.

What we like:

  • 2000 gallons capacity per day
  • The compact and durable build of the unit

What we don’t like:

  • Very Expensive 

Best suited for:

The reverse osmosis filtration system is great for Hotels, Hospitals, Factories, Car Washes, Restaurants, and more. It improves the taste of food and drinks and protects appliances that use water like boilers or water heaters.

Commercial Water Filter Types

Different types of impurities require different types of water filters for making them safe for drinking. Tap water contaminants vary depending on the source and can be treated using different types of filters. The different types of commercial water filter are:

Reverse Osmosis

Reverse osmosis filters are surface filters that remove contaminants using membrane screens. The contaminated fluid is forced through the membrane by applying pressure. The water that comes out of the filter is free of most of the contaminants from water.

The contaminants are removed depending on the size of the membrane pores. If the particle size is greater than the membrane pores then they are trapped there but smaller contaminants can pass through.

A reverse osmosis filter can be used to remove limescale, salts, and nitrates. However, there is a lot of wastewater in these filters.

UV Filters

The UV water filter system uses ultraviolet rays to kill the harmful substances in the water. It is one of the most effective methods for disinfecting bacteria from drinking water. The UV rays penetrate the harmful pathogens and eliminate their ability to reproduce.

The contaminants from the water are removed without adding any chemicals to the water which retains the water’s taste. UV filter treatment should be used for poor water sources.

Carbon Filters

Carbon filters use activated carbon granules that have been burnt at a high temperature in limited oxygen. These filters can remove harmful contaminants such as pesticides, chlorine, manganese, iron, and hydrogen sulfide.

Carbon filters need to be replaced after a few months to avoid clogging pipes with impurities. 


Commercial water filters help increase the efficacy of industrial operations. We have provided a list of the best commercial water filters that have been built for different industrial functions.

If you want a standard commercial water filter with the basic functions then we recommend that you go for Light Commercial Reverse Osmosis Water Filtration System.

For low maintenance and highly efficient water filter, we suggest the WECO HydroSense Reverse Osmosis Water Filter. It is a bit expensive but the features that it provides are worth it.
