How To Pick The Right Filter For You
When selecting a hot water filter it is necessary to attempt to personalize your search, by looking at different criteria, such as size, storage, type of water, number of people and any other personal requirements that will make you more comfortable with your choice.
Here are a few questions to ask yourself as you begin the process of looking for a water filter or filtration system that will work best for you.
What type of water will you be feeding into the filter?
Not all filters do the same job, some are better at removing chlorine and chemicals while others are better suited to remove sediments and particles.
It is important to know what kind of water you have to pick the best fit for your needs.
For example, a person whose needs pertain to well water would best be suited to the iSpring model, while a person whose needs pertain to city water would be best suited to the Home Master model.
How many people will the water filter be serving?
Each water filter or filtration system comes with a capacity in terms of bathrooms, storage, output and other capacity factors.
It is advisable to find a model that suits your particular needs.
For example, Pelican often offers different options for the same model.
The PSE2000 model is suited to accommodate the needs of 4-6 bathrooms, while their PSE1800 model is suited to accommodate 1-3 bathrooms.
Do you need a system that is inserted at the point of entry of all water supplies or the point of use?
Different systems can be placed in different places.
Some will be placed at the point of entry and will filter all water that is used, while others are inserted at the point of use, meaning that they only filter the water at that specific outlet e.g a faucet.
How much space do you have?
Filters all come in different shapes and sizes.
Some can be kept under the sink for easy placement, while others are much larger and need a lot more space.
Some filters and systems are suited to be kept outdoors if the option is more appealing to you.
If you’re in a small house, apartment, large house or have any other requirements different models may suit different needs.
Some models even come with a mounting bracket to put your filter up on your wall.
Would you like to DIY or hire a professional?
Many options on the list above boast easy to understand manuals and full packages that come with all required parts for a simple installation that anyone can do with basic plumbing understanding.
If you however would prefer to have someone else fit in your filter for you, a professional can do that.
It is important however to note that not all warranties will be viable if you don’t get the system professionally installed such as the Aquasana Rhoni 10 Year Pro Kit at the top of this list.
