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.

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.
