Therefore, don’t expect such a filter can remove all the pollutants in the water. Any system that can remove any amount of sediment, particles, bacteria, chlorine and other contaminants can be called a water filtration. If a system has a water filter of any type, it is a water filtration system.
Types of Filtration
Water filtration systems have many types, and each type has their own abilities to get rid of different types of contaminants:
Carbon filters: They normally contain activated carbon charcoal, so they are also called as activated carbon charcoal filters. They are widely used in many water filtration systems. For example, water pitcher filters include carbon filters. Some tap installed (inline water filters) or faucet-mount water filters (faucet water filters) use carbon filters as other main filters. Even a typical reverse osmosis system also uses carbon filters in the first some stages.
UV light filters (ultraviolet (UV) light filters): They are a little special, because they use ultraviolet light to kill bacteria, viruses and other organisms in our water. If you notice there are a large amount of organisms in your water, you can get one to kill them. Of course, they can be a separate filter. And some RO systems also include a UV filter to kill bacteria and viruses.
Reverse osmosis filters: Reverse osmosis is a regarded as one of the most effective ways to purify water. It uses a semi-membrane to only allow water to pass through and other contaminants are left on the other side of the membrane. Therefore, it uses a different way to purify water. Most other types of filters remove contaminants from water, while a RO system removes water from contaminants.
On the market, there are several types of water filtration systems use a RO filter as their core water filter to remove contaminants. For example, most under sink water filters (more than 4 stages water filters) are reverse osmosis systems, and some countertop water filters are also reverse osmosis systems.
Water Distillers: As one type of water purifiers, they are different from most water filters. They heat water to boil and liquid water will become steam and rise. This process separate water from contaminants which are left in the boiling chamber, because they cannot become steam in such a temperature. Of course, most water distillers also have a post water filter (a carbon filter) to remove VOCs in distilled water.
These types of filtration systems are very common in our home, so they also be known as home water filter systems. Of course, public water treatment plants or larger scale municipal water treatment plants may be different or use some of them.
Some home appliances also include a water filter, like refrigerators, water cooler dispensers, etc.
Which Type to Buy
Of course, on the market, there are many types of water filters. If you are going to buy one, your final decision will be determined by your water condition. Before investing in a home water filter system, you need to test your water first. And you can buy a home water test kit to do it yourself, or you can ask a professional to help you. If your water quality is bad and not potable, you may need a whole house or an under sink water filter that can remove contaminants and kill bacteria and viruses to make your water potable. Or if you only want to remove the bad taste caused by chorine, a water filter pitcher or a faucet water filter may be good enough.
Anyway, if you don’t know how to start, your local water experts can give you some valuable suggestions.
Once your demand on water quality has been confirmed, you can choose a specific filtration system to remedy your water to make your water potable. Purchase costs, ease of the installation, and further maintenance costs will be discussed. And don’t worry about. There are so many different models on the market and you can buy the right one. Most of them are more affordable than before.
How to Install a Home Filter
Most water filtration systems are designed to be easy to install. Anyone with basic DIY skills can install them.
The installation of under sink water filters
Although they are designed to be simple to install, compared to other types, the installation can be a little complicated. You can read its instructions or watch some installation videos, which can help you install such a system with ease. Another way is to hire a plumber to do the job, if you cannot install it.
The installation of carbon filters
Most of them are easy to install. You can do it yourself in 2 or 3 steps. For example, the installation of an inline filter only needs you to connect it to the water line.
The installation of water distillers
Actually, they are home appliances. A typical home distillers only needs you to install its nozzle and put the filter in. That’s all. You only need to take 2 or 3 minutes.
The installation of UV light filters
Most of them require no installation. You only need to know how to use them. If they are a separate system, you need to connect it to the electricity. If they are a part of a RO system, refer to the installation of an under sink water filter.
How to Keep It Clean
No matter which type of water filtration system you choose, maintenance should be done on a regular basis. And this can make your system work more efficient.
For water filters, you need to change its filters every 6 to 12 months. Different models require differently and the source water quality can also influence the water filter life. You can do it yourself, or you can choose a water specialist to do it for you.
For water distillers, you need to clean its boiling chamber. It is recommended to clean it every 1 or 2 week, or too much scale on the bottom will influence the work efficiency.
The Bottom Line
We need potable water to drink. If our tap or well water is not potable or contaminants or tastes that can influence our health, we need a home water filtration system to purify water.
