Types of Water Filters
There are different types of water filters and understanding the most popular ones will help you make the best choice depending on where you stay and the impurities in it. This is how you know the best water filtration systems in Phoenix. Here are some of the most common water filters you may be choosing from:
-
Activated Carbon Filters
These filters make use of a material known as activated carbon which has a high surface area to trap the contaminants and prevent it from passing through.
It is useful for removing impurities like chlorine, bad taste, odor, and organic compounds. The most common types of activated compound are Granulated Activated Carbon (GAC) and Carbon Block filters.
-
Reverse Osmosis (RO)
In a reverse osmosis filter, the water is forced through a semi permeable membrane that removes contaminants like salts and dissolved solids when it comes through the other side.
It is generally effective in removing heavy metals from the water.Ro filters have high contaminant removal rate so they are great options for drinking water filtration.
-
UV Purification
Here ultraviolet light is used to kill bacteria and viruses in the water. Bear in mind that it does not remove sediments.
-
Ion Exchange
Like the name implies, an ion exchange filter exchanges unwanted ions like calcium in the water with useful ions that usually softens the water. It is best used for softening hard water.
-
Sediment Filters
Are there lots of solids in your water whether rust, dirt, or even sand? Sediment filters are the perfect type to remove these sediments.
Water Filter Systems: Which Should You Choose?
Knowing the types of filters and their uses is not enough, you should also know the different systems. Water filtration systems can be fixed differently depending on your needs. Here are the main systems:
Whole-House Filters
This filtration system is fixed to the main water source coming into the house and filters the water before it gets in. This way all the water in the house is filtered. They are also typically more expensive.
Under-Sink Filers
This type is placed under the sink and connected to the pipes underneath. An under sink filter will purify the water before it reaches the faucet. And just like whole-house filters, may require a professional for installation.
Faucet-Mounted Filters
These are small, usually affordable filters that are mounted directly on the faucet so it filters the water leaving the nozzle. It is usually easy to install but can make the facet bulky. While convenient, their lifespan is limited.
Countertop Filters
Countertop filters are standalones, away from the water sources. They are often jug-like where water is poured into and the filter works to produce clean water in a different chamber.
Factors To Consider Before Choosing a Filtration System
Before you make that decision, there are a few factors that can ensure you make an even better choice. Here are the factors to consider while choosing a filter:
Cost: consider the cost of the filter while including installation cost if any, upfront and long-term cost, as well as the cost of the filter.
Maintenance: some of these filters require frequent maintenance to keep working. So you need to consider this before making a decision.
Lifespan: filters like countertops and faucet-mounted filters have the shortest lifespans. Whole-house fi;ters last the longest, so you want to put this into consideration while making a decision.
Impact on Water Pressure: some of these filters reduce the water pressure from your taps while others, not so much. Filters like the whole-house systems do not affect the water pressure while faucet mounted filtration systems reduce water pressure.
Finally
Choosing the right water filtration system for your home needs will protect you and your family from a lot of issues including diseases and unpleasant water.
The busying decision can be a whole lot easier if you know what you’re looking for. These filters all have strong points, the type of impurities they remove best, so knowing which impurities in your water is the first step.
