Choosing Between Backwashing and Non-Backwashing Whole House Water Filters: A Complete Guide for Florida Homeowners
When it comes to protecting your home’s water supply, whole house water filtration systems offer two primary approaches: backwashing and non-backwashing systems. Each has distinct advantages and drawbacks that can significantly impact your water quality, maintenance routine, and long-term costs. Understanding these differences is crucial for making an informed decision that best serves your household’s needs.
Understanding Backwashing Whole House Filters
Backwashing filters use a self-cleaning process where the control valve initiates a “backwash” to clean the medium of collected particles and to resettle the bed. This is accomplished by sending water down the riser tube from which it enters the filter tank at the bottom. The force of the water actually lifts the media bed, swirling and tossing the granular medium, with water leaving the filter tank through the control valve and routing through the filter’s drain line.
A whole house backwashing filter cleans all the water that enters your house, making it pure, fresh, and free of contaminants. This type of system is capable of filtering heavy contaminant loads by trapping them inside the filter media and rinsing them away periodically. In other words, the backwashing refreshes the filter media sending all contaminants down the drain.
How Non-Backwashing Systems Work
Non-backwashing systems use a canister—made of plastic or stainless steel—that holds a replaceable filter or membrane to trap sediment, chlorine, and other impurities. Some advanced cartridge systems with ultrafiltration membranes feature a backwash function to flush out contaminants, extending filter life. Cartridge systems require regular filter replacements, ensuring fresh filtration media with no fouling or efficiency loss.
Pros of Backwashing Systems
Backwashing prevents a pressure drop in your water supply and allows the media to be reused, so it lasts much longer than a filter cartridge – usually upwards of 5 years. The process maintains a steady flow of filtered water without affecting water pressure and prevents the accumulation of mold and bacteria inside the tank, greatly reducing the risk of microbiological contamination.
Tank-based systems auto-backwash and are virtually maintenance-free. Media life will depend on the type of media used in your backwash filter, available backwash flow rate and the concentration of contaminants treated. NEXT sand is advertised to last 5 year or longer. Katalox light recommended media life is 7-10 years. Catalytic carbon backwash filters typically need media changed every 4-6 years.
Cons of Backwashing Systems
Tank based systems require more space, electricity to operate the control valve and connection to a drain pipe. We recommend hiring a plumber to do the installation. Please note that a minimum of 20 psi (1.4 bar) of water pressure is required for the backwash/regeneration valve to operate effectively.
Backwash filter systems cost more upfront than cartridge setups. Most quality systems fall in the $900–$2500 range. If you’re hiring a plumber, add another 50% for installation.
Pros of Non-Backwashing Systems
Cartridge based filters are much cheaper upfront, easier to install and does not require much space. They do not require a drain connection and can even operate at low house water pressures. A non-backwashing system is less expensive and doesn’t require a connection to a drain pipe.
With cartridge systems, you get fresh performance with every filter change, while backwash tanks rely on aging media that degrades over time, leading to reduced effectiveness and costly replacements.
Cons of Non-Backwashing Systems
However, the filter cartridges may need frequent replacement depending on your water quality and water use. Unfortunately, cartridge based filters can severely restrict the water flow and pressure. However, it does require more maintenance in that you have to replace sediment filters.
Cartridge-based systems require annual filter changes, and these filter replacements are more expensive than the media used in backwashing systems, so after just a few years, a cartridge system is actually more expensive.
Which System Is Right for Your Florida Home?
The best choice depends on your household’s water quality concerns, space availability, maintenance preferences, and budget. For most homeowners, a cartridge filtration system offers the best balance of efficiency, water quality, and long-term savings. With consistent performance, lower maintenance, easier installation, and no wasted water from backwashing, cartridge systems provide a hassle-free and cost-effective solution for clean, safe water.
However, for homes with high sediment levels or specific water quality challenges, backwashing systems may provide superior long-term value despite higher upfront costs.
