Why Big Blue Water Filter?

Why Big Blue Water Filter



The Big Blue water filter purifies the water as it enters your home. So, you are sure to get quality and safe water whether you are using it for bath, tea, or laundry.




Getting a point-of-use (POU) filter is more expensive than getting a whole house water system. Also, the cost of maintenance is high. But with a Big Blue water filter, you only have one system to deal with and maintain. It's a lot cheaper.



Big Blue water filter cartridge doesn't have an intricate working mechanism. The company also has active customer assistance to ensure using it is simple. The multi-stage filtration system provides total water safety from contaminants that most point of use filters cannot deliver.

Buying Guide of Big Blue Water Filter

Before buying a Big Blue water filter, you will need to check out some of these factors, especially if you want to have undisrupted water flow.

Water Flow

Water Flow

This factor depends on the number of your household. Water coming from the system should be sufficient for running your activity effectively. So, if you have a small house, you may require a filter system that can produce about ten gallons of water. But for a larger family or commercial use, you may need those that can produce ten gallons upwards.

Filter Type

The filter system you need also depends on the contaminants you have in your water. For heavy metal contamination, you can get filters with the regular copper-zinc mineral. However, to remove bacteria and other pollutants, UV filters will serve.

Filter Size

The filter size depends on the number of people you have in your household. The best size for most houses is 4.5 by 20 inches, while for an enormous family, you can get a filter with a 25gpm flow rate.

Filter Life

This varies with the type of filter you have. If you have a sediment filter, the filter life depends on the sediment's quality and quantity. But with carbon filters, get those that have a lifespan of 100,000- 150,000 gallons from a tap water supply. However, those with carbon beds last longer when backwashing regularly.

Port Size

The port size is the connection point of your filter to the water inlet. The minimum ideal port point is 1 inch to reduce pressure. A one-inch port system is still active even in a house with ¾ inch piping as it will not cause any bottleneck. Also, a filter size with 4.5 by 20 inches will always carry enough water with a 1-inch port without any drop in pressure.

How Often Do You Change a Big Blue Water Filter?

How Often Do You Change a Big Blue Water Filter?

The Big Blue water filter housing has a durable build and can last for up to ten years. However, the company advises changing the system after ten years. Further usage may result in cracks and disruption of your water filtration process. And as for the cartridge, you should replace them after three months of use.

Cleaning and Maintenance of Big Blue Water Filter

Cleaning your Big Blue water filter can be quite straightforward. However, it is best to change it completely.


To drain out the water from the filtration system and tank and take out the filter. Then, fill a bucket with clean water, add two cups of muriatic acid and stir with a plastic stirrer. 

Cleaning and Maintenance of Big Blue Water Filter


Rinse your filter from build-up until it's clean. After rinsing, place it in the solution, and let it sink. 


Allow the filter to remain in the solution for a minimum of five days, at room temperature, to remove all the dirt. Then remove it and soak in clean water for another five minutes.

Afterward, remove and rinse it with a hose until clean, then reinstall.

How Does the Big Blue Water Filter Work?

Though the water purification methods of most Blue water filters vary, the mechanism remains the same.

Then it gets to another filter made up of copper-zinc. It is an essential step as it removes contaminants left in the water like microorganisms, bacteria, and other heavy metals.

How Does the Big Blue Water Filter Work?


Water enters the filter through the main water line, where all contaminants are removed before entering your appliances for usage.


First, the water enters into the sediment filter, where it takes out large particles such as dust, rust, sand, and silts. The sediment filter is the bedrock for other filtering processes as it makes other filters last for a more extended period.


Water then goes to the second activated carbon filter where chemical contaminants like chlorine, organic compounds, and other sediment residue are removed. The carbon filter also removes bad taste and smell from the water.

Big Blue Water Filter Cartridge FAQs

Do I Need a Water Softener for a Big Blue Filter?

It depends on the type of water you have. If you have hard water, placing a Big Blue filter before your softener will prevent the softener from sediments and help it effectively reduce your water's hardness.

What Does Big Blue Filter Housing Remove?

The filter housing does not remove anything. All it does is to direct water flow around the filter cartridge you put inside. What does the filtering is the cartridge by separating the water from the contaminants, so if there's no filter in the cartridge, the cartridge does nothing.

How Do I Know the Type of Big Blue Water Filter I Need?

The type of water filter you need depends significantly on your water quality. If your water has an odor, sediments, or chemicals, you should go for a product like iSpring with a carbon filter to remove chlorine and smell, as well as a sediment filter.

Why Should I Replace My Filter?

After a long time, your filter's ability to trap contaminants may reduce clogging and reduce the free-flow of your water. So, replacing your filter will enable them to work as they should.

How Often Should I Clean My Water Filter?

Cleaning your water filter depends on the amount of water consumption, the hardness of water, etc. However, it is advisable to clean your water filter after every forty gallons of filtration for more powerful performance.

Final Words of Recommendation

Good water supply is essential for healthy living, and a Big Blue water filter has proven effective. The product ensures every family, company, and industry gets the best, quality water supply.


It is a perfect way to ride your water from contaminants and particles, whether tap or well water. It does not just remove bad smell from your water; it also ensures you and your family are free from parasites and bacteria.


If you require an effective water filter option that can purify and ensure your water is safe from bacteria and sediments, then the iSpring water is what you need.

However, if you use well water or require a water filter to serve commercial purposes, I recommend Aquaboon as it can filter effectively, even with high-pressure water.
