Q7           Whyis water obtained from a water purifier tasteless?

A7           Rehana Al Mahari,3y

An RO waterpurifier alters the water taste. The reason is quite simple, as it 
filters out the salts.

 

The taste willbe great if the TDS is in between 50-80.

The taste willbe bitter, tasteless or salty if the TDS is lesser than 50 and 
greater than 80.

Water takes ittastes from the impurities contained in it like minerals etc.If 
you begin with water that has a lot of contaminations & taste, and runit 
through a refining process, the better the purifier (i.e., the more scums 
iteliminates from the water, the less palate your water will have the 
followingpurification. Triple distilled water is very pure water, and 
verytasteless. Indeed,what little taste very uncontaminated water has it will 
pick up from what isalready in your mouth.

You canchoose LivPure smart Purification Technology: RO + UV + UF + Taste 
Enhancer.It’s a 7-step water purification process which purifies the water
