Why would you need a whole house water filtering system?

If you’re going to get one, then you must at least know what you’re signing up for. We’ve lost trust in tap water ever since the River Flint Water Crisis hit the headlines.

Even though our municipalities are trying their best to supply us with treated water, our drinking water is still full of contaminants like dirt, rust, excess chlorine, heavy metals, bacteria, viruses, and other toxic micro-particles. The responsibility of protecting our health and that of our families now rests on our shoulders.

It’s large body houses the filtering system that is responsible for all the cleaning. It’s a Point-of-Entry (POE) filtering system. This means it filters water at the entrance before it’s distributed to the entire house. Its main objective is to make sure all areas of your house are supplied with clean filtered water.

Not to mention the annual maintenance fees and filter replacement costs. The Big Blue whole house filtering system is cheaper in the long run.

The housing

Big Blue’s housing is surprisingly durable and can last up to 10 years of continuous everyday usage. This has a lot to do with its durable material that is flexible enough to accommodate forces of inertia created when a water outlet is closed. You’ll find some suppliers selling transparent water filtering systems. They are a no-no. Clear plastic is brittle and will easily fracture and break with continuous use.


The manufacturer advises us to replace the individual filters once every three months.

Is it worth it?

Yes, the Big Blue Water Filtering system is efficient, saves you money in the long run, and it’s very durable. What more could you ask of a high-quality whole-house water filtering system?
