Whole House Water Filtration Systems Are The Only Long-Term Option For Sediment

by admin on February 20, 2014


Filtering Sediment Out of Drinking WaterThere is no one way that sediment will appear in your water.  Depending on where you live, and what type of water quality you have, water sediment may be large or small, dirty or sandy, fine or gritty.

As there are so many unique ways that water sediment issues can rear there ugly head, where do you start to solve the issue?

Whole House Water Filtration Systems Are Only Optional To A Point
At the most basic level, if you have water sediment issues in your home, you will eventually need to invest in a whole house water filtration system in order to gain complete control over the issue.  Why whole house? Because sediment will leave an impact in every pipe and from every faucet, whether that means a sandy glass of drinking water or a corroded interior of a washing machine.  This is not too say that there are no point-of-use systems that will not act as perfectly fine short term solutions, including shower filters or even washing machine filters, only that a whole house system will be necessary if you are trying to solve this issue once and for all.

Selecting Your Filter Housing
There are five industry standard whole house water filter housings, based on cartridge size – 5″ x 2.5″, 10″ x 2.5″, 20″ x 2.5″, 10″ x 4.5″ and 20″ x 4.5″.  The system pictured below is a Pentek Big Blue system that uses a 20″ x 4.5″ cartridge.

Pentek Big Blue Whole House Water Filter HousingFar too many homeowners that install a whole house water filter err on the side of small, while for most, a larger housing will be a more ideal solution. Flow rates will be better, pressure loss will be less, time between cartridge changes will be longer and water filter cost will be lower per square inch of media.

I’m not trying to indicate that you will need the biggest filter housing available, only that when buying a whole house system, it’s sometimes better to err on the side of large rather than small.  If you are unsure at this point whether you need a smaller or larger housing, I invite you to call our customer service department at 1-888-801-PURE (7873.)

Choosing Your Water Filter Cartridge Type
When choosing your whole house water filter cartridge, you’ll first want to determine whether your water is treated or untreated.  If you have untreated water you absolutely must avoid any cartridge made of cellulose media.

Cellulose is derived from plants and is therefore a feast of food for any microorganism lucky enough to find your filter, where he will live, grow, multiply and potentially cause serious threats to your health. Cellulose is most often found in pleated cartridges, but some manufacturers also produce pressed cellulose cartridges.

Untreated water requires the use of a bacteriostatic filter media. Bacteriostatic simply means that microorganisms will not live and grow on the filter.  The most common bacteriostatic media is polypropylene, though polyester is also bacteriostatic.

There are two common types of polypropylene water filters; string wound and spun. The string wound water filters look just like the name indicates; a spool of tightly wound string. The spun are made from the same polypropylene, but the poly is melted and blown out of a gun and spun onto a cartridge, sort of like cotton candy.

Hydronix Pleated Sediment Water FilterThey have nearly identical performance, and are perfect for sediment removal from untreated water. For better flow and lower pressure loss consider a pleated polyester sediment water filter, like the 20″ x 4.5″ Hydronix filter to the left. The pleats give the filter more surface area than a poly string wound or poly spun water filter.

For treated water you could use any of the filter types already mentioned, but there’s no reason to look any further than pleated cellulose. Pleats offer more surface area, thus better flow with lower pressure loss. Pleated cellulose water filters are almost always the best choice for treated water.

A final option open to you when selecting whole house water filter cartridge is brand specific.  RUSCO water filters are sediment filters designed for large particulate over 75 microns and are commonly used to filter irrigation water to protect the sprinkler heads from clogging.

The most popular aspect of the RUSCO filter line is their ability to be cleaned and reused, courtesy of a flush valve to purge out the collected sediment and rinse off the cartridge. No replacing cartridges, but they don’t work well with sediment smaller than 75 microns.
