Mike Verified Buyer – 4 November 2024

This is exactly what we needed. We have the Apec 7 stage system in our home and love it. This summer we are in a rental with no filtered water. After a couple of weeks hauling 5 gallon jugs to and from the store I decided to explore countertop RO systems. We landed on this one because we’ve been so happy with the under sink system.

We love it. The reservoir is large enough to supply plenty of drinking water, while not being too heavy to lift. I usually fill all of our containers first thing in the morning, and then top off the system to be used throughout the day on demand. It’s working out great so far, and the unit actually looks very nice.

Background before buying APEC
I’m familiar with RO water and prefer it over anything else. I also used RO filter in Thailand and when I moved to USA I thought the water quality would be better so I wasn’t looking for RO filter. I used tap water for cooking and drinking by filtering with Brita before but I personally hated it because there’s still chlorine smell and honestly you can’t trust water quality these days because there’s a lot of contamination in it so Ineeded better filtration.

Water quality
It’s RO so quality is as good as the bottled water. No chlorine smell. Water has taste but it has no sharp feeling when drinking. If you’re worried that RO will get rid of minerals in the water, to be honest, you can get minerals from somewhere else – cooking, supplemental pills etc. Having access to non contaminated water is my priority.

Filtration system
When you use up one cycle it takes 90 seconds to filter new cycle in it. It doesn’t take long at all. The noise can be high but it never really bothers me as it’s a quick process. The vdo I attached is of when it’s filtering new tank.

Suitable for 2 people with small animals. We are a couple and have 2 cats with big tank of water fountain. I also cook a lot. Bigger household should consider under the sink installation instead. We use tap water, it’s NOT suitable for well water.

Design is modern with decent materials. It’s convenient especially those living in an apartment where you’re not allowed to drill.

Wilson Verified Buyer – 14 April 2025

I bought this APEC tankless unit to replace an older APEC model with a tank and 5 filters. The water on the new unit tastes good but not quite as good as with the old tankless model. This unit was installed by my plumber. It looks great inside the cabinet and I’m happy to no longer struggle to replace the 5 filters. I will sacrifice a bit of water quality for the convenience of this tankless unit. I don’t find the sound of the motor bothersome. It’s about the same noise level as the nearby Subzero refrigerator. The plumber had to put a fitting on the blue tubing so it would accept my faucet which is a water filter faucet that matches the other finishes in my kitchen. APEC could provide more instruction on installing with customers own faucet and provide the piece needed. Also, the water had to run a long time for the flashing red light to turn solid blue. Longer than the 30 minutes listed, more like 40 minutes. Overall, I like the unit and would buy again.
