Buying Guide
If you know what to look for while choosing a residential water filter, picking the right one for your needs will be a hundred times easier.
The following guidelines will help you a lot to choose the best home water filtration systems.
Types of filtration and Price
Make sure your money is well-spent. But how?
It’s not essential to have a fancy system that filters out contaminant of your water.
Before deciding on a system, get your water tested to find what you need to filter out. Then choose a water filter certified to do the job.
You don’t need to spend your hard-earned cash on an overkill. Also, never go for the cheap option as your health is a concern.
For example, if you already have soft water supply, you don’t need a water softener. But if you have a well-water source or have iron in water, you need a water filter for well water with iron. So, if your filtration system is affordable but it has no capability to remove the existing containants in your water supply, it’s a waste of your money.
Filter Capacity
It doesn’t indicate the physical size of the filter. Instead, it’s the capacity of the unit to filter the water. In general, a standard whole house water system can filter up to 1 million gallons of water. Keep in mind that the larger the unit is in its physical size, the larger the capacity.
Flow Rate
Based on the number of your family members or the size of your house, choose the required flowrate. For a larger family, you’ll need a unit with a high flow rate to cater to the water needs of every member. The higher the flow rate (GPM), the higher the chances of getting steady water pressure.
When calculating the demand, take into consideration the flow ratings printed on your appliances. Count the total fixtures of your home and individual flow rate. Your flow rate requirements may range between 12 to 40 GPM.
Also, note that the port size affects the water pressure. The ideal port size for a whole house filtration system is 1-inch to avoid pressure drops.
System lifespan/ Filter life
You don’t want a home water treatment system that requires to change the filter every month. Right?
The lifespan of a filtering system depends on the filter type, level of water contaminants, flow rates, and the amount you use. A system with replaceable filter/ cartridge requires to change the filter at least every six months. However, there are filtration systems that work well for years or even a decade.
The sediment filter life varies on the sediment quantity.
In general, a good quality whole house 4.5 by 20-inch carbon filter cartridge filters 100,000 to 150,000 gallons of normal municipal water.
Certifications
Check the certifications of water filtration systems. You can check if your model has NSF or WQA seal on it.
These certifications ensure that the system is tested by the most prestigious organizations in America and has passed the rigorous testing for its quality.
Keep in mind that if any model isn’t certified by NSF, it doesn’t mean that it’s of low quality.
Some manufacturers do the testing in the independent laboratory against ANSI/ NSF standards. If the labs are well trusted, the certification is meaningful.
How Does a Whole House Water Filter Work?
The working mechanism of a single filter and a whole house filtration system isn’t the same. There is a clear distinction.
You need to set up a whole house water filtration system at the point of entry of water into your home. For this reason, it’s also known as the Point of Entry (POE) system.
Most of the units filter the contaminant water by following a 3-stage process.
The First Stage
It’s a pre-filtering stage. A pre-filter is used to remove the larger contaminants and impurities. This stage helps to prevent clogging in the system.
The Second Stage
It involves mainly the removal of chlorine. A special filter is used to eliminate the chlorine that makes both the color and taste of your water terrible.
The Third Stage
This step involves removing any other leftover impurities existing in the water. The system includes a carbon filter or activated charcoal filter to do this job.
Some models further purify this filtered water using a reverse osmosis system or a water softening system.
Installing Whole House Water Filter
Without prior knowledge, whole house water filter installation is difficult for a novice. But don’t despair.
Only a little knowledge can help you to handle the process. You may need to take a bit more time than it’ll take for a plumber or professional to do the job.
This how-to guide will help you to learn the basic installation principles.
Tools and supplies needed for the job:
- A pipe cutter
- Drill
- Copper coupling
- An adjustable wrench
- Slip joint push fitting
- Valves
- Teflon tape
- Pressure gauge
Follow the steps below:
Step 1: Turn off the water from the main source of your home.
Step 2: Drain out most of the water. For this, you can turn on the kitchen sink faucet allowing the water to run out.
Step 3: Choose the location where you plan to install the filtration system.
Step 4: Measure the pipes correctly and mark off the spots for the pressure gauges and shut-off valve. Cut the pipe by using a pipe cutter.
Step 5: Insert the shut-off valves at the end of both pipes on your main supply pipe.
Step 6: Mount the filter system by following the manufacturer’s instructions. Apply the Teflon tape where necessary to keep it sealed to prevent leakages.
Step 7: Attach the pipes you cut initially and the unit’s pipes together. Use a compression nut or push fittings to do this.
Step 8: Attach the unit’s input and output to the push fittings.
How to Change Whole House Water Filter Cartridge
Need to change the filter of the standard whole house water system?
It’s a pretty simple task!
In this section, I’ll show you how to do this.
You may need the following-
- Filter wrench (usually, it comes with the system)
- New filter
- A bucket
Follow the process:
Step 1: Restrict the water flow by using the shut-off valve.
Step 2: Turn on the sink tap to drain out the water in the pipe system.
Step 3: If your filtration system has any release button, press it.
Step 4: Place a bucket under the filter housing to collect any extra water.
Step 5: Insert the filter wrench underneath the housing and turn. Loosen the housing and slowly turn it out. The housing will come off. Pour the water (if any) left in the filter.
Step 6: Remove the cartridge or filter from the housing and place it another bucket.
Step 7: Clean the housing to remove the dirt. Rinse it thoroughly.
Step 8: Put the new cartridge/ filter in its correct position inside the housing.
Step 9: Screw back the housing to the system.
Step 10: Turn on the shut-off valve to run the water.
