While distillation and reverse osmosis systems produce water cleaner than you would normally get out of your tap, the treatment processes are completely different.To create distilled water, the water is boiled and evaporated, leaving dissolved solids behind. The vapor is then condensed, and the clean water is collected in another container.RO filtration uses pumps and a semipermeable membrane to produce clean water.While you can find both distilled water and RO-filtered water in stores and at home, RO water filtration systems are much more practical and common.

Cypress gives you a visual structure of suites, tests, and assertions. Soon you'll also see commands, page events, network requests, and more.

Cypress automatically detects things like a page transition event and will automatically halt running commands until the next page has finished loading.

Over in the Command Log you'll see Cypress display the suite, the test and your first assertion (which should be passing in green).

We mentioned previously that Cypress waited 4 seconds before timing out finding a DOM element - but in this case, when Cypress detects a page transition event it automatically increases the timeout to 60 seconds for the single PAGE LOAD event.

Notice Cypress displays a message about this being the default page on the righthand side. Cypress assumes you'll want to go out and visit a URL on the internet - but it can also work just fine without that.

An RO system can last up to 10 years if maintained properly. However, the filters will need to be changed according to the instructions that come with your system (usually every year).

Cypress builds on these popular tools and frameworks that you hopefully already have some familiarity and knowledge of. If not, that's okay too.

Osmosis is the natural tendency of water molecules to move through a semipermeable membrane in a way that results in an equal concentration of any substances dissolved in the water (such as salts or ions) on both sides of the membrane.

And there you have it: a short test in Cypress that visits a page, finds and clicks a link, verifies the URL and then verifies the behavior of an element on the new page. If we read it out loud, it might sound like:

There are a few different types of reverse osmosis systems that requires different levels of installation. Most people are able to install the undersink RO systems following the instruction manual. They do require drilling to install the faucet and drain saddle.

2. Reverse OsmosisNext, high-pressure pumps force the water through a semipermeable membrane. The membrane allows pure water to pass through while filtering out particles like salts, minerals, metals, and most bacteria and viruses.When the process is complete, one side of the membrane will have pure water, and the other side will have leftover water with a higher concentration of contaminants. This unfiltered water is released down your drain.After this step, some systems may use additional specialty filters to pick up any remaining contaminants or a remineralizing filter to add back healthyminerals.3. StorageOnce the water has been completely filtered, a typical RO system with a storage tank will collect the water. Then, anytime you turn on the faucet for filtered water, you’ll have a supply ready for your use—no need to wait for water to go through the filtration process.

Ok, now we want to click on the link we found. How do we do that? Add a .click() command to the end of the previous command, like so:

Waterborne bacteria and viruses can lead to serious illnesses. Recommended by the CDC, APEC’s reverse osmosis systems effectively remove bacteria from water and eliminate harmful microorganisms, offering the highest protection for your family’s health with virus removal water filters.

In other words, based on the commands and the events happening, Cypress automatically alters its expected timeouts to match web application behavior.

Let's make an assertion about something on the new page we clicked into. Perhaps we'd like to make sure the new URL is the expected URL. We can do that by looking up the URL and chaining an assertion to it with .should().

First, let's visit a web page. We will visit our Kitchen Sink application in this example so that you can try Cypress out without needing to worry about finding a page to test.

We can pass the URL we want to visit to cy.visit(). Let's replace our previous test with the one below that actually visits a page:

Can you see what Cypress is doing under the hood? It's automatically waiting and retrying because it expects the content to eventually be found in the DOM. It doesn't immediately fail!

As the name suggests, reverse osmosis takes this process and reverses it, using pressure to push water through a semipermeable membrane that blocks larger particles from passing. This results in pure water on one side of the membrane, with almost all contaminants left behind on the other.

Cypress also displays the stack trace and the code frame where the assertion failed (when available). You can click on the blue file link to open the file where the error occurred in your preferred file opener. To read more about the error's display, read about Debugging Errors.

You might also see this phrased as "Given, When, Then", or "Arrange, Act, Assert". But the idea is: First you put the application into a specific state, then you take some action in the application that causes it to change, and finally you check the resulting application state.

We can use cy.get() to select an element based on its class. Then we can use the .type() command to enter text into the selected input. Finally, we can verify that the value of the input reflects the text that was typed with another .should().

RO systems can produce waste water while producing clean drinking water. And every system will require routine maintenance such as filter change. RO water filters remove almost all minerals from water, including healthy minerals. But there are many systems include a re-mineralizer, which adds healthy minerals back to the filtered water.

In general, the structure of your test should flow query -> query -> command or assertion(s). It's best practice not to chain anything after an action command; for more details on why this is, see our guide on retry-ability.

PFAS, also called "forever chemicals", are a growing concern in water contamination. APEC Water’s carbon and reverse osmosis filtration systems can remove up to 99.99% of many harmful contaminants, including PFAS, ensuring PFAS-free drinking water and protecting your family’s health.

APEC offers RO systems in all shapes and sizes to suit different needs. Here are the three main types of RO systems you can choosefrom.1. Tankless RO SystemsTankless RO systems are among the most convenient because they’re small enough to fit almost anywhere. They don’t have a water reservoir, so they’re compact and visually pleasing. However, they need a 110 V outlet, as they operate with electricity.These systems are built for everyday consumers with an extremely easy filter-changing process. You can replace a used filter in just a fewseconds—just twist and pull to remove, then push on the new filter.2. Traditional RO SystemsA traditional RO system has a tank that holds 4 gallons of water, so the water dispenses faster than from a tankless system. It also ensures you always have clean water available, even if your water supply is temporarily shut off. It does, however, require more space than other options.If you feel intimidated by this system, don’t be. Even though it's bigger than a tankless system, it actually has a simpler configuration. You can clearly see all parts of the system, making it easy to identify problems.3. Countertop RO SystemsA countertop RO system is a perfect option for renters and small spaces. It takes up very little space and is easy to install and maintain.The system operates with electricity and has a water reservoir you fill instead of connecting to your tap water supply. It can also dispense hot water thanks to preset and custom temperature settings.

Generally speaking, the point of Cypress is to be a tool you use every day to build and test your own applications, not a general purpose web automation tool. However, this is a guideline rather than a hard-and-fast rule and there are a number of good reasons to make exceptions for certain kinds of application:

We are not limited to a single interaction and assertion in a given test. In fact, many interactions in an application may require multiple steps and are likely to change your application state in more than one way.

Mineralized/Alkaline water is slightly less acidic than regular drinking water. A reverse osmosis water filtration system adds alkaline minerals at its last stage after the water is filtered through an RO membrane.

Chlorine is commonly used to disinfect city water, but overexposure can cause skin irritation, bleach-like odors, and other unwanted effects. Our premium activated carbon filters, featured in APEC water filtration systems, effectively remove chlorine from tap water to deliver cleaner, better-tasting water.

A reverse osmosis system typically requires regular filter replacements, usually every 6 months to 1 year for pre-filters and post-filters, while the RO membrane itself should be replaced every 2-5 years depending on water quality and usage.

An RO system connects to your tap water line and uses a sophisticated process to purify the water. This process can be broken down into three key steps.1. Pre-FiltrationFirst, water enters the system and passes through a series of filters designed to remove larger particles from the water. They remove substances like:

Yes, reverse osmosis is considered the best way to filter water at home. It is one of the most effective methods of removing wide range of contaminants, including dissolved solids, chemicals, heavy metals, bacteria, viruses, PFAS, and more.

Reverse osmosis water is clean and healthy. Reverse osmosis water from a maintained RO system is the same quality if not better than bottled water.

Your tap water, though deemed drinkable by local processing facilities, is likely not free from impurities. A reverse osmosis water filter system removes unwanted inclusions like dirt, bacteria, salts, and minerals from your home water source so your water is cleaner, healthier, and better tasting.
