The bottom line

What the product listing won't tell you

Know before you buy

No gallon-based filter capacity is published — APEC uses time-based schedules only, which don't account for your household's actual water usage. Installation requires drilling a new sink hole, so this is homeowners-only.

Buy it if

You own your home and are comfortable with a 2–3 hour DIY under-sink installation.

You want strong, independently certified RO protection at a price well below countertop alternatives.

You're fine managing filter replacement by calendar rather than by gallon count.

You want on-demand filtered water from a dedicated faucet without occupying counter space.

Skip if

You're renting or cannot drill a new hole in your sink.
You need to know exactly how many gallons each filter lasts — APEC doesn't publish this.
You want a professional service relationship or automatic maintenance reminders.
