Filtered Water vs Tap Water (What’s the Difference?)

What makes filtered water and tap water different?

Are you able to differentiate the two?

Well, let’s learn about this.

What is filtered water?

This is water that has undergone some sort of purification treatment to eliminate contaminants. This purification process may involve the use of chemical methods, charcoal filters, or reverse osmosis filters.

Filtered water benefits 

  • Removes chlorine: Filtering gets rid of chlorine which is harmful to health from water.
  • Tastes better: Filtration removes the chlorine and bacteria that give water a bland, metallic, or chemical taste. 
  • Improves digestion: Filtered water has a healthy mineral content which promotes healthy digestion.
  • Saves money: Filtered water is cost-efficient.


  • Some filtration methods like reverse osmosis get rid of all water contents, good or bad. This leaves it without healthy minerals.
  • Filters need regular replacement to avoid contaminating the water even more.
  • High initial installation costs
  • Filtered water lacks fluoride, crucial for dental health, putting you at risk of teeth decay.

What is tap water?

This is water delivered to our homes through faucets or taps. The water is derived from lakes, deep wells, rivers, and reservoirs and goes through a treatment plant before being piped.

Health benefits of tap water

  • Contains healthy minerals: since it travels through rock foundations, tap water has minerals like magnesium and calcium.
  • Has fluoride: It has added fluoride for teeth and bone health.
  • Convenient: Tap water is readily available even in public places.
  • Safety: Tap water is treated to remove impurities hence safe and healthy for consumption.


  • Safety of the water may vary: Some locations are more exposed to toxins that may contaminate tap water.
  • Old pipes may contaminate the water with lead and copper, making it unsafe for drinking.
  • Contains chlorine: Tap water is treated with chlorine which has adverse impacts on health when continually consumed.


Is tap water the same as filtered water?

No. Filtered water has undergone some sort of purification to remove impediments and contaminants. Tap water, on the other hand, is simply water that comes out of your faucets.

Is it better to filter tap water?

Filtration can, without doubt, result in cost-effectiveness, better taste, and control over what’s in the water that you drink, then filtered tap water is better. But if you want convenience, bottled water takes the crown. 

Are water filters a waste of money?

It depends on the quality of the water. If you live in an area with low water standards, water filters will come in handy as they help remove contaminants from your water and making it safe for consumption. But, if your locality has clean, high-quality water, filters will not be necessary.

Does filtered water have minerals?

It depends on the type of filtration technology used by your filter. Some methods like reverse osmosis remove all minerals from water. Carbon filters retain most of the minerals.


The choice between tap water and filtered water depends on individual preferences. What’s important is the quality of your water.
