APEC ROES-50
★★★★★
"Best investment for our kitchen."
Installation took about an hour with basic tools. Water tastes noticeably different — the whole family drinks more water now. Filter changes are straightforward.

★★★★★
"Nothing else compares for off-grid."
We use this at our cabin with lake water. The Black Berkey elements are incredible — water comes out crystal clear. It's gravity-fed so no power needed. Perfect for our setup.

★★★★☆
"TDS meter convinced me."
The included TDS meter showed my tap water at 380 ppm and the filtered water at 000. That visual proof sold me. Filters need replacing more often than Brita but the quality is worth it.

"Every tap in the house."
Installed this in the garage where the main line comes in. Every shower, every sink, every appliance now gets filtered water. The difference in shower water alone was worth it.

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.

"Tastes like premium bottled water."
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.

Buying Guide
Four questions to find your filter
Answer these before buying and you'll 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.
What is in your water?
Test your tap water with a home kit before buying. PFAS, heavy metals, or fluoride need a certified RO or gravity system. Chlorine and taste may only need a carbon filter.
How many people are in your home?
One person can manage with a pitcher. Families of three or more will benefit from an under-sink or countertop gravity system with higher daily output.
What is your budget?
Good filtration is available at every price point. A $30 Brita provides genuine improvement. Spending more buys higher capacity, less frequent filter changes, and broader contaminant removal.
