APEC ROES-50
★★★★★
"Completely transformed our tap water."
We live in an area with very hard, chlorinated water. After installing the APEC the difference was immediate — no more taste or smell. My husband now drinks from the tap for the first time in years. Took about 45 minutes to install.

"Worth every penny. We use it every day."
After 2 years of daily use this is the best purchase I have made for my family. Crystal clear water, no electricity needed, and I have replaced the filters just once. Total peace of mind about what we are drinking.

ZeroWater Pitcher
★★★★★
"TDS went from 312 to 000. Remarkable."
I tested my tap water — 312 ppm dissolved solids. After the ZeroWater filter it read 000. That result says everything. Great option if you do not want to install anything under the sink. Filters last about 2 months for our family of four.

"Every tap in the house is now filtered."
Had a plumber install this in about 2 hours. The difference in our showers, laundry, and cooking water is noticeable. Clothes come out softer, skin feels better. Worth every penny for complete whole-house coverage.

Clearly Filtered Pitcher
★★★★★
"The only pitcher certified to remove PFAS."
I spent months researching before buying. Clearly Filtered is the only pitcher independently certified for PFAS removal. As a parent this is non-negotiable. Higher price than Brita — completely justified by what it actually removes.

★★★★★
"Tastes like premium bottled water. Every time."
The tankless design is a game changer — no tank taking up space under the sink. Water is instant, the smart faucet is genuinely useful, and the quality is exceptional. Expensive but worth it if you care about what you drink.

Buying Guide
Four questions to find your filter
Answer these before buying and you will make the right choice first time.
Do you rent or own?
Renters should stick to pitcher or countertop options — no installation needed and you take them when you leave. Homeowners have the full range available including under-sink and whole-house systems.
What is in your water?
Test your tap water with a home kit before buying. If you have fluoride, PFAS, or heavy metals you need a certified reverse osmosis or gravity system. Sediment and chlorine only may need just a basic carbon filter.
How many people are in your home?
One person can manage well with a pitcher. Families of three or more will benefit more from an under-sink or countertop gravity system with a higher daily output capacity.
What is your budget?
Good filtration is available at every price point. A $30 Brita pitcher provides genuine improvement. Spending more buys higher capacity, less frequent filter changes, and removal of a wider range of contaminants.
