Water filter features
What is important about correctly measuring and applying the dimensions of a product to the space that you are wanting to affix the system to is extremely important. For the obvious reason that you want to buy something that is right and will fit to its surroundings with ease. But also you need to make sure that these dimensions are accurate, because of the different kind of system that can be obtained.
Goes without saying really that a whole house water filter that does not offer a spectrum of temperature to work with is no good. The sweet spot for a temperature range can be found in between the 30’s and the higher 110’s. Making sure that you have cold and nourishing drinking water, but some good heat to help wash the dishes.
Now, the filter is really the most important part of the filtration system as it is the barrier between unhealthy and healthy. Keeping sediment from the stomach. What you need to look for when comparing filters is how frequently they need to be changed and how many gallons you are being guaranteed in its lifespan.
When looking into the frequency of changing your filter, try to opt for one that needs changing monthly at least. The higher the change rate, the more reliable the water that comes from your tap. This is really more for your own piece of mind, knowing that the water you’re getting is freshly filtered as opposed to having one that has sat in your system for months at a time.
And when looking into gallons held in a life span, the bigger the better. The higher the number of gallons that a product boasts to filter in its lifespan, usually, the seller offers a fantastic warranty guarantee as they are so sure of their product. If worst comes to worse, and something should happen, it is always good to be covered.
POE or POU
POE (Point of Entry), and POU (Point of Use) are the leading reasons as to why you need to pay close attention to the dimensions of the space you need the product to be.
- Point of Entry means that the piping system can be added straight to your water supply. Ready to go, easy to use, done. POE are mostly found from smaller water filters. POE piping systems are perfect for smaller living spaces as they are accommodating and easy to use.
- Point of Use is made up of a larger selection of piping that goes from the water source to a separate area for a filter, and then your faucets, through a series of changes in course. POU systems are then, instead, found in larger homes where there is more space to maneuver such piping.
Simply put, if you have a smaller home and have less space available for your whole house water filter, you are better off looking into purchasing a Point of Entry system. And, if you have a larger home with more space to offer for piping, then you could look more into Point of Use systems.
Both systems work brilliantly. It is more just a question of installation, the space that it would be taking up, and for aesthetics.
What is Reverse Osmosis System?
A Reverse Osmosis water filter is technology that uses a fine mesh membrane and the water pressure already available in your room. Then water pressure pushes salt and sediment toward the filter system and it is there by destroyed by the semi-permeable membrane. A simple way to approach sediments in your water.
