Should I Buy a Whole House Reverse Osmosis Filtration System?
We really consider this as an investment, considering all the things and illnesses that can be caused due to not having clean water. This way you can have peace of mind, knowing you are drinking the cleanest and purest water there is, not just yourself but your whole family too. These systems have proved that they are doing an amazing job, yes they can be a little pricey, but if you are in need of one, and can afford a whole house reverse osmosis system then we say with upper confidence that your money is well spent.
What Is A Whole House Reverse Osmosis System And How Does It Work?
The reverse osmosis system removes feed water, or simply removes all the harmful contaminants from your water. The RO system has a pre-filter that removes sediment and chlorine, after passing the pre-filter the water going into the semipermeable membrane that does not allow anything but water to pass. After the water goes through the membrane it goes into a postfilter, this is used for polishing the water before going into your faucet. These filters can vary depending on what reverse osmosis system you use.
What Contaminants Does The Reverse Osmosis System Remove?
Although it removes almost every contaminant in the water, here are some of the most important ones.
What Are The Things You Need To Look For When Buying Your New Whole House Reverse Osmosis System?
Like every other appliance on the market, the whole house reverse osmosis system is a big purchase, so you are going to need to be careful and know what to look for to make the right choice. The whole house reverse osmosis system needs to have some great features to sway you into buying him, here are the most important ones you need to look for.
- Flow rate. The flow rate of the system is the first thing you need to look for, and also you need to know your daily usage approximately. The flow rate of systems nowadays is between 100 and 500 gallons, a regular person uses around 80 gallons a day. If you have a family of four, then you are going to need at least 250 gallons a day of production.
- Filtration stages. This is very simple, more stages, cleaner water. If the reverse osmosis system has four stages of filtration, it would be a lot better than those with two stages of filtration. Although the more filters the system has, the more maintenance it’s going to ask for. This also means buying more filters and the cost goes up.
- The installation. This one saves you a headache, some reverse osmosis systems come pre-built, meaning you only have to connect a few things, but some of the systems are quite complicated that you are going to need to waste a day or two installing it by yourself or even call a professional.
- The wastewater. This feature is really important for you to be economic about your water usage. The difference usually varies from one manufacturer to another, but mostly is in the limit of 1:1 to 1:1.5, this means that for every gallon of clean and purified water produced there are five gallons of wastewater.
- Does it have a tank? Some households don’t have the space to go for a large tank reverse osmosis system, so for smaller houses, it’s better to look for a tankless filtration system. There are a lot of oversized reverse osmosis systems on the market.
- The water pressure. The municipal waters are almost always with a good flow rate, but if you attach your whole house reverse osmosis system to it then the water pressure might drop significantly. Now, most RO systems have a 40 PSI ( pounds per square inch) water pressure, so that’s the number you need to look for when buying.
What Is The Best Whole House Reverse Osmosis System On The Market?
If you are going to buy a new whole house reverse osmosis system, we know it can be very difficult to make the right choice. There are so many things to keep in mind, things like the size, the wastewater production, the cost of filter maintenance, the installation, the filter capabilities… Do we need to go on?
