“ Many "filters" solely enhance the taste of your water, not the safety.
When in doubt, solely purchase products certified by NSF Worldwide.
Filters remove physical particles, like micro organism and lead,
however some contaminants are just too small or diluted to be caught and separated with a bodily mesh screen.
But a filter alone is sort of always adequate to keep you
protected. That stated, some nonetheless-legit firms promote third-social
gathering testing from labs like Envirotek (sometimes recognized because the "Quality Filter Testing Laboratory").
Be skeptical of promoting language - if it’s imprecise
or sketchy, listen to your intestine, particularly with low-cost unknown brands on websites like
Amazon. That’s when purification comes in (typically with UV, chemicals, or boiling).
You’ll want special desalination gear. Some products declare
to be "tested to NSF standards", which is not the same factor as truly being certified and thus will
be gamed by unethical entrepreneurs. Don’t put water from an ocean or pool into these products. ”
