Why Should One Consider A Carbon Block Filter?

Farewell Contaminants

Carbon block filters are supremely porous.

This means that like a sponge, carbon filters allow water to be absorbed and cleaned by merely passing through it.

These filters are capable of removing particles like asbestos, cysts, certain pesticides, trihalomethanes, and volatile organic compounds (VOCs).

A benefit of carbon filters is that they require no chemicals.

They also don’t strip the water of its naturally occurring salts and minerals.

Easy Replacement

The replacement of these filters is easy.

As long as you follow the product’s installation guide, you’ll be drinking clean water until a replacement is due.

And since there is an abundant category to choose from among carbon block filters, you’ll never struggle to find a replacement filter.

Budget-Friendly

These filters are the cheapest filters on the market because of their naturally occurring material.

This news is not only good for your water but your wallet.

Easy-Breezy

Carbon block filters are the easiest to maintain.

There’s no maintenance involved.

About every three months, depending on your average water consumption, you’ll need to replace the filter.

Keeps Minerals

Not only does activated charcoal purify the water, but it also keeps the nutrients that already exist within it rather than stripping everything away.

Additionally, charcoal adds minerals such as calcium, magnesium, and iron.

Final Thoughts

Life on Earth began in water and evolved from it.

You have personal experience with this dependence each time you seek water fluids to quench your thirst and replenish your body’s water content.

Water circulates through our body without rest and causes the macromolecules (proteins, enzymes, and genes) and cells in the body to function properly.

Our natural water resources are under a great deal of stress as we battle with an ever-changing climate, pollution, and the needs of a rapidly growing population.

Given the importance of water to our wellbeing & every bodily function, we owe it to ourselves to ensure that the water we drink is as pure & fresh as possible!
