Perfect water filter

The newest model of the Opti water filter is flawless. The water is delicious, the basin is large and functional, and it fits in a fridge that does not have tall spaces between shelves. Great customer service too. 10/10

No More Bottled Water

I love Opti water filter. It gives me peace of mind knowing I will have clean, filtered water all the time. It also saves my back from lifting the heavy bottled water while saving the environment from plastic bottles.

So far so good

Everything went together easily and I have been drinking the water instead of bottled water. It’s Ph test was as good as the bottled water I used. So I’m glad to have a replacement for bottles.

Our Water Infrastructure is Crumbling

Over 9 million lead service lines still deliver drinking water to U.S. homes today.

Most of the country’s water infrastructure is over 100 years old, corroded, and leaching toxic metals.

2x Longer Lasting Protection from Lead, Microplastics + more

Each Opti Water™filter keeps you protected for 3–4 months (or 200 gallons) — twice as long as brands like Brita and PUR — while removing the most dangerous tap water toxins, including lead, microplastics, PFAs (forever chemicals), chlorine, mercury, copper, and other heavy metals.

PREMIUM FILTRATION

Organic Filtration Compounds

Opti Water™ Filters use premium solid coconut carbon and a proprietary blend of adsorption compounds to remove 99.99% of harmful contaminants, enhance alkalinity, and preserve essential minerals.
