There’s something you should know about your water: it’s not as clean as you might think.
In fact, depending on where it comes from, you could be having that skinny half-caf latte with extra primordial soup. Lots of little living things are in your drinking water right now, right in this moment. There are also plenty of minerals and more complicated compounds floating around in it, maybe even agricultural waste, if you get the drift.
It’s a pretty unpleasant picture, there’s no doubt about it. But without water, we mere mortals won’t last long. Just how do you keep from drinking a slurry that would potentially give you superpowers if you were in a comic book?
Water Filters for the Masses
Anyone who has a well should understand the need for regular testing and heavy filtration to protect their families from the things that can concentrate in the water supply, but most people who are on municipal water don’t give it a second thought. And why should they? Water goes to a treatment plant and it comes back as pure and glistening as new fallen snow.
Except that’s not really true. There are always contaminates that can’t be filtered out, no matter how hard you try. The technology is getting better all the time, but until it’s perfect, you may want to take some of the work of cleaning your drinking water into your own hands.
What Can a Water Filter Do?
There are plenty of water filters on the market today, mostly because many can only cover a portion of the contamination spectrum. It’s a lot to ask of one filter, though. The way you capture protozoa and eliminate them is completely different from how you’d get rid of excess calcium.
Unfortunately, this isn’t made very clear by those filter manufacturers. What ends up happening in many cases is that homeowners buy a single filter and are disappointed that their water is still kind of dirty.
For most whole-home filtration systems, using more than one type of filter will get you the best results possible. You will not get water that is perfectly free of anything but a couple of Hs and an O, but it will be much better overall.
Types of Filters
As mentioned above, there are several types of filters out there, most of which only cover a limited range of impurities. Some remove biological contamination from your water, but will not remove chemicals. These include:
Others are really good at getting the chemicals, but don’t do much for things like cysts and bacteria.
A few popular filters and techniques on that list are:
- Activated Carbon
- Ion exchange
Then, you have reverse osmosis.
Reverse Osmosis for Household Water Filtration
This particular filter technology as it’s regularly deployed to homeowners is a multipart system that not only includes a semipermeable membrane that prevents water contaminants like arsenic, hexavalent chromium, nitrates and perchlorate from entering your faucets, a carbon filter comes along with most standard systems to catch chlorine and other materials.
Part of what makes a reverse osmosis system so effective at cleaning your water are the multiple filtration stages. Of course water’s going to be cleaner with several polishes rather than the single pass your Brita pitcher gets.
The typical reverse osmosis filtration system uses pre-filtration to eliminate sand, dirt, silt and other sediments, carbon filters to remove chlorine and organic compounds, as well as the reverse osmosis membrane. By installing a reverse osmosis system, you are really installing multiple water filters that work together to create very clean water.
The Flip Side of Reverse Osmosis
Mostly, reverse osmosis systems are really pretty amazing. They do a lot of work without complaining much and need minimal maintenance if they’re installed properly. However, nothing in this world is perfect and the reverse osmosis filtration systems do have a few drawbacks to consider:
- Not all systems are the same. Just because many reverse osmosis systems include multiple pre-filters, it should not be assumed that the one you’re looking at on Amazon does. The quality of reverse osmosis systems varies dramatically, make sure you read the reviews and invest in a good system that will last.
- You need decent water pressure. Because the water has to be forced through what is essentially a super fine mesh, you need decent water pressure for a reverse osmosis system to work. If you’ve had water pressure issues in the shower, it’s a good bet you need a plumber out to take a look before you spend the money on a reverse osmosis filtration system.
- They use a lot of water. Many homeowners are surprised to see how much waste water their reverse osmosis system produces. How much discharge water is collected will vary based on local water conditions and the number and types of filters you use, but you can expect something like three to five gallons of discharge water per gallon of reverse osmosis purified water. The waste water, however, is totally useable for anything you’d use the purified water for, aside from consumption by humans or animals. Hook it up to your gray water discharge system and water your trees with it — it’s not wasted anymore!
Ready for Reverse Osmosis? Not Sure Where to Start?
Sure, you can buy that system from Amazon and hope that you know enough about your plumbing to set it up properly, but wouldn’t you rather be in the pool or kicking back on the sofa watching the game?
You don’t have to do it all yourself. Your HomeKeepr community is home to the best plumbers in your area. They’re happy to help you with that reverse osmosis system. Your real estate agent has probably already recommended a plumber, why not log in right now and see who it is? Not only will your recommended expert help you choose a level of filtration that works for your family, they’ll install it in no time.
