Let’s get started!
SimPure Y7 Countertop Reverse Osmosis System Overview
The SimPure Y7 Countertop Reverse Osmosis system, like the name suggests, is a countertop RO system so it won’t require installation, and can be easily placed in a countertop, office, RV, or apartment unit.
One of our favorite features is its outstanding efficiency, as it only wastes 1 gallon of water for every 5 gallons of water filtered, which is much better than the typical RO system which wastes 3 to 4 gallons of water for each gallon of filtered water. This means that you will not only save much more money in the long run, but it is also a more environmentally friendly option than most RO systems.
The SimPure Y7 Countertop Reverse Osmosis system is NSF certified, ensuring that it can remove up to 99.99% of more than 1.000 harmful contaminants, through a 4-stage process that includes a UV step that destroys nasty water pathogens.
The manufacturer offers a 30-day refund and 1-year limited warranty which shows the trust that they have in its product, and allows you to try it without worries.
SimPure Y7 Countertop Reverse Osmosis Filtration Capabilities
The SimPure Y7 Countertop Reverse Osmosis system can reduce 90% of TDS (total dissolved solids) and remove up to 99.99% of more than 1.000 harmful contaminants such as chlorine, bacteria, viruses, heavy metals (lead, mercury, arsenic, etc.), fluoride, VOCs, chemicals, pesticides, herbicides, PFOA, PFOS, carcinogens, pharmaceuticals, bad taste & odors, etc.
This high contaminant reduction capability is achieved through a 4-stage filtration process, that contains the following steps:
- Stage 1: Sediment PP Membrane, which removes larger contaminants like sediments, cloudiness, and other larger impurities from the water
- Stage 2: Activated Carbon Filter, which removes several contaminants like chlorine and chloramines, chemicals, VOCs, etc.
- Stage 3: ultra-fine 0.0001-micron RO Membrane, which removes 99.99% of contaminants, leaving your water virtually contaminant-free
- Stage 4: UV sterilization, which destroys viruses, bacteria, microorganisms, germs, and other pathogens
The SimPure Y7 Countertop Reverse Osmosis system has NSF 58 certification which ensures that this product was independently tested to be able to reduce TDS, removing harmful contaminants like chlorine, heavy metals, fluoride, limescale, and much more.
SimPure Y7 Countertop Reverse Osmosis Design Features
The SimPure Y7 Countertop Reverse Osmosis system has many design features that are worth highlighting.
First, it is a countertop unit which means it doesn’t require installation and can be placed almost anywhere, as long as you can connect to electricity.
The sleek and modern design of the SimPure Y7 Countertop RO system makes it a great fit for most kitchens.
It comes with a removable tank, so if you prefer cold water you can place the filtered water tank on the refrigerator.
It includes a modern digital display that lets you know when to change each of the filters, and when you need to fill the water tank, so you won’t have to keep track of these things.
The SimPure Y7 Countertop Reverse Osmosis allows you to run shorter filtration cycles so you can fill just one glass of water, or filter smaller water quantities (180, 350, or 450 ml), so you won’t have to wait long if you are in a hurry.

And changing the filters is quite simple, as its design includes quick-change filters that you only need to twist/rotate to remove and replace with a new one.
SimPure Y7 Countertop Reverse Osmosis Performance
The SimPure Y7 has one of the best performance of the RO systems available, as its waste ratio is 5:1, meaning that it only wastes 1 gallon of water per 5 gallons of filtered water, which is an 83.3% efficiency.
This is much better than the average RO system that generates 3 or 4 gallons of waste water for each gallon of filtered water, making the SimPure Y7 RO more environmentally friendly than the competition.
This compares amazingly against the competition, as the average RO generates 3 or 4 gallons of waste water for each gallon of filtered water (1:3 to 1:4 waste water ratio), making it one of the most efficient, if not the most efficient Reverse Osmosis system in the market!
SimPure Y7 Countertop Reverse Osmosis Capacity
The SimPure Y7 Countertop RO system is not directly connected to the main water line like other conventional under-sink RO systems, so you will need to fill its tank manually so that the system has water to filter.
But the tank has a nice capacity of 1.3 gallons (5L) and the filtration process will take a few minutes to fill the pure water tank that has a capacity of 0.45 gallons (1.8L) of filtered water.
You can also run shorter filtration processes that will filter only a glass (180ml), 350ml, or 450ml, so that you won’t have to wait for a full filtration cycle in case you are in a hurry and need just a small amount of water.
The SimPure Y7 Countertop RO system can filter up to 418 gallons of water per day, so the filtration process is quite fast.
SimPure Y7 Countertop Reverse Osmosis Installation & Maintenance
A regular Reverse Osmosis system installation process is somewhat complex, as you would need to drill through the sink to install a specific faucet, and will also need to connect the system to the main water line.
But the SimPure Y7 Countertop Reverse Osmosis system is quite different from a regular RO system, so no installation is required, only the initial setup of the system. You only need to place it in the kitchen or whatever place you want to use it (as long as it is near an electric outlet as it needs electricity to work) and it’s ready to use.

You can watch in the video below how easy it is to do the initial setup:
Maintaining the SimPure Y7 Countertop Reverse Osmosis system is easy and straightforward. This system uses 2 filter cartridges, the CF filter with the PP Sediment Membrane & Pre-Carbon Block that lasts between 3 to 6 months, and the RO Filter which contains the UF RO Membrane that should last for 6 to 12 months, so you will only have to replace the filters a few times a year.
The device will let you know when it is time to change the filters, and replacing them will take only a few seconds as you just have to turn, rotate, remove, plug the new one, and rotate again.

The system also includes a flush button so that you can run flush cycles a few times a year to make sure the SimPure Y7 continues to run without issues.
Because no installation is required and due to its compact design, you can easily have it at home, office, or RV, and move it from one place to another if needed.
