The Taste of UK

We human are made up of more than 60 percent of water.

But unfortunately most water nowadays are polluted with toxic chemicals to harmful bacteria and virus that can make us sick and in some cases can kill us. In this environment it is essential that we either boil the water before drinking or use high quality water filters. But with so many types of water filters available on the market it is not easier to decide which one is best for you. In this article I will be discussing about how you can choose best water filters of 2019 so that you can have clean and pure drinking water for you and your family.

Is bottled water safe?

Bottled water is a huge industry as we haul water all up and down the road trying to guarantee a safe water supply. But is bottled water the answer? It’s certainly an environmental disaster. What with all the bottles in landfills and all the fuel burned up transporting water over land and sea. And most bottled water is still just filtered municipal water anyhow…

Is Reverse Osmosis System the Best?

The reverse osmosis water filter system may be the best choice for you. They aren’t the cheapest filtering systems, but these filters are the best answer for many people. They also take out all the minerals too. That’s somewhat controversial.

Water goes from your tap through this really fine filter. That filter is a really fine mesh membrane that gets out all the toxic chemicals and minerals plus many drugs that end up in our water. Did you know there are lots of drugs in city water? Why these filters will even take out tiny radioactive particles. How’s that? Well the trick is that your water pressure forces part of your water through the filter membrane.

But part of the water doesn’t make it through the filter membrane. That waste water takes all the bad stuff away. The filtered out stuff goes down the drain and the water that’s left is pure and clean. See that’s also why these filters are cheap to use… the bad stuff doesn’t clog the filters. Only clean water actually makes it into the filter medium.

Now there are some other tricks. The system contains carbon filters too. Carbon filters are really good at some kind of filtering. Carbon really gives the water the best taste you can get too. You’ll find that many doctors and health care people recommend these filters because they do get so many toxic things out of the water.

DI filter, DeIonisation, mixed bed resin, filterhousings

Some people use the resin without a reverse osmosis unit to make 0ppm water, but it is expensive. In a reverse osmosis system the DI-filter MUST be placed after the membrane, which typically makes water with 20-50µS (10-25ppm). Thus, the water is already well filtered before it comes to the DI filter, and thus the resin last longer. A cartridge to be inserted in a 10″ filter housing. The cartridge can be refilled with approx. 400 gram. The advantage with this one compared to the small 0.25 filter is that the filter housing stands upright, and the water always flows properly from below and upwards.

You can put both A and B at any system AFTER the membrane, but most people with a small 3-stages system prefer the small 0,25 liter inline filter A). If you have a system with large filter housings, you might prefer the cartridges B). See below under Capacity

If you have a system with 3 large filter housings linked with tubes, you might want to use the third housing as resin filter and in this way you avoid buying another filter housing. Remember that the resin filter must come AFTER the membrane. With some (cheaper) RO systems, the filter housings are built together and NOT connected with tubes and with these system you cannot do it.

How to fill the filterhousingss

I’ve read in a german forum from a professional. How important it is, I do not know, but it does not hurt to do it this way: No small grains must move. If there is too much play in the filter container, the individual parts of the ions connect to each other. Fill the resin slowly in small portions in the container, then fill enough water slowly until the water is just above the resin.

Slightly rotate and swing your container so air bubbles can disappear. Continue this way until the container is full.

The water must be forced to meet so many resin balls as possible with as much contact as possible. If the resin is not packed very well, the water might find its own way without encountering too many resin beads.

Capacity

Published several places and my preliminary studies show: The greater the volume of resin and the slower the water runs through the resin filter, the cleaner the water. And from an experienced german person I have been told:

After an osmosis system 1 liter resin purifies 800-1200 liters of water by 30-40µS to 0-1µS at a flow rate of approx. 10 liters per hour.
