Water filters for home and farm.

Home page.

Not all water quality problems for rural homes, farms and properties can be solved easily. But there are some simple steps folks can take to improve the quality of their drinking water. Provided water is reasonably clear and clean, and this is often the case, simple cartridge systems may improve the look of the water, make the water taste better and offer protection against water borne diseases.


For example rainwater is usually fairly clear and the risk of diseases is low. In this case choose a dual cartridge system with a sediment cartridge and a carbon cartridge. Most particles that come from roofs or gutters can be handled easily by a standard 1 micron sediment cartridge. The carbon cartridge will help protect against unwanted smells that sometimes develope in tanks especially if they ae sealed and have little turnover or aeration. The KX Matrikx +1 cartridge is a good choice. It has a nominal rating of 0.6 micron and an absolute rating of 2 microns. By the way nominal rating means that this cartridge will stop around 85% of particles above 0.6 micron and the absolute rating means that this cartridge will stop around 99.9% of particles above 2 microns.

Cartridges for rainwater tanks can last 6 months or longer. You will easily notice when the flow from the tap starts to decrease, that's time to change the cartridges - check the sediment cartridge first. Most pressure pumps will handle the Matrikx +1 but if yours is making hard work of it try a Matikx CTO carbon cartridge. These have a nominal rating of 5 microns and absolute rating of 10 microns.

Spring water

Under spring water we include any water that is relatively protected but still may have had some contact with the ground. So in quality this might be in-between water in a rain water tank and water from a creek or dam. You will need a cartridge that will filter some fine sediment and also provide some protection from bacteria and other water born pathogens like protozoans. In this case choose a KX Matrikx CR1 cartridge as the first cartridge and a Ceramic cartridge as the second cartridge.


Farm / rural spring water system. The carbon cartridge is a Matrikx CR1 and the second cartridge is a ceramic cartridge such as the Doulton Sterasyl cartridge. Water has to flow through the carbon cartridge first and the ceramic cartridge second. To help your installation the housings can be reversed so the flow can be L to R or R to L.

The Matrikx CR1 has a nominal rating of 0.5 microns and an absolute rating of 1 micron so it will act as a barrier against water borne single celled animals like protozoans. It will aslo double as an effective sediment filter. The ceramic cartridge is even finer and will greatly reduce bacteria in the water. Ceramic cartridges last for quite a while as they can be taken out periodically and cleaned with a synthetic scouring pad. At Apps Labs we have tested ceramic cartridges and found them to be very effective against bacteria. We only confirmed what the manufacturers were saying! See the details at Ceramic test report.

Dam or river water.

This is likely to be water with a little more sediment and maybe more cloudiness. Also there may be pathogens present because this water could be exposed to runoff, animals and other contaminants. We suggest a dual cartridge system with an additional UV step. The first cartridge should be a standard 1 micron sediment cartridge. These cartridges are relatively cheap so they be changed more frequently if required. The second cartridge should be a fairly fine carbon cartridge such as the Matrikx CR1. These are designed to protect against waterborne protozan pathogens. All Matrikx carbon cartridges provide additional sediment filtration. The final stage should be a UV sterilizer. These are compact and are mounted over the top of the dual housings with an easy connection after the final cartridge. The smallest Aquapro UV system can provide 4.5 L/min. UV is very effective against bacteria. See details of this filter at Drinking water UV system.

Apps Laboratories is a water testing lab so we provide pre testing to help decide on a filter that's suitable for your water. You will also want to do a treated water test to check if your filter is working. Again we do the tests or can even provide DIY kits for bacteria testing. See details of the basic water quality test at Start testing your water.
