It was very easy to order what I needed online. Then when we had a problem with kinked tubing, APEC sent a replacement promptly.

Dear Valued Customer,
Thank you for taking the time to share your feedback. We sincerely apologize for the inconvenience you experienced. Hairline cracks or pinholes in the filter housings are often linked to sudden or consistently high water pressure entering the system, which over time can lead to plastic fatigue. We recommend checking your water pressure at your earliest convenience to ensure it does not exceed 80 psi, as higher pressure may increase the risk of leaks or damage.
We’re always here to help if you encounter any issues with your system. Please feel free to contact us at 800-880-4808. We’re available Monday to Friday from 8 AM to 5 PM Pacific Time, and our team is dedicated to providing you with a 5-star customer service experience. We’ll do everything we can to assist you and ensure you continue to enjoy your water filtration system.
Best Regards,
APEC Customer Service
Everything needed was delivered in the box. Nothing missing. My plumber was able to do everything needed to hook up the system based on provided instructions. When I called APEC with a question, a real person answered (not a robot) and he was very polite and professional. Now, that is what I call outstanding customer service!

I was very disappointed with the AI responses. I had my water shut off and they were so slow that I ended up buying another system. I requested a person call me each email, but no one did. It took days and I finally diagnosed the probem myself.

Great pricing on a quality product! Recently setup the 50GPD unit in my basement to feed our fridge ice maker as well as a sink faucet. It's been working great so far! Kids are happy to no longer see "floaties" (mineral solids) in their drinks after ice melts.

I purchased the APEC tankless system, and its the most substantial upgrade I've made to my apartment and my quality of life in a decade. I appreciate the certifications and third party testing because the quality of my water isn't negotiable. The install was straightforward, the system is beautifully built, and the water iI get from it is incredible. All that's to say, I'm extremely satisfied, and offer my highest endorsement of this product and company.

The people I worked with were friendly and helpful but I had to wait three weeks to get replacement parts. This mean I had the under sink area pulled apart and a mess for that long. New parts leaked though. I bought another new filter set, it also leaked. In the end I ordered so many individual parts it would have been cheaper and faster to buy a whole new system. Very frustrating experience.

My filter was installed in the kitchen and started leaking from the edges. Customer service on the phone immediately told me what photos and information to send, and I did. That is when I started getting AI answers to my email that instructed me to go under the sink twice to provide ever more data, serial numbers, and photos, repeating what I had already provided. And it would not pass me to a human. Crazy. Just crazy. Finally got a human on email and they immediately sent a replacement filter, as they had originally promised. So that part was ok.
