How to choose
Common questions
What is a commercial grade water filter?
It is a system built to handle higher flow rates and larger volumes than residential filters. They often use bigger housings and more robust media to serve businesses, restaurants, or large homes.
How often should I replace commercial water filters?
It depends on water quality and usage. Some filters last 3 to 6 months, while others can last years. Always follow the manufacturer’s guidelines and monitor water pressure and taste.
Can I install a commercial filter myself?
Some point-of-entry filters are DIY friendly. Whole house or high capacity systems may require a plumber due to complex connections. Always check local codes and warranty requirements.
What contaminants do commercial filters remove?
Common removals include chlorine, sediment, VOCs, heavy metals like lead and mercury, and sometimes bacteria. Reverse osmosis systems can remove even more, including fluoride and arsenic.
Are commercial filters certified?
Many are certified by NSF or WQA. Look for certifications that match your needs, such as NSF/ANSI 42 for aesthetics and 53 for health contaminants. Always verify the specific claims.
What is the difference between whole house and point-of-use filters?
Whole house filters treat all water entering the building. Point-of-use units treat water at one tap, like under a sink. Commercial kitchens often use a combination for different needs.
How much maintenance do these systems require?
Regular maintenance includes replacing cartridges, cleaning housings, and sometimes sanitizing. High capacity systems may have larger filters that need less frequent changes but still require periodic inspection.
Can I use a commercial filter in a residential home?
Yes, some are designed for large homes. They offer benefits like better flow and longer filter life, but may require more space and a higher budget.
Our take
For most businesses and large homes, the Aquasana Rhino system is the top pick due to its massive capacity and minimal upkeep. If you need high flow for a restaurant, the 3M Aqua-Pure is a solid choice. Budget conscious buyers should consider the iSpring system, which provides good performance at a lower cost.
