Upgrade your home’s water quality with the APEC WTS-MAX-15. This whole house filtration system is designed to remove a wide range of contaminants, ensuring clean and safe water for your family. Also available with additional fabric coat or stainless steel coat.
The Whole-House-Max 15 System uses advance state-of-the-art catalytic carbon to effectively adsorb difficult chemicals like chloramines which cannot be effectively removed by regular activated carbon filters - plus, it also removes a wide range of chemical and organic contaminants from water including chlorine, VOCs & odors. This new generation whole house water filter incorporates an automatic electronic control head to enhance performance and service life while eliminating the extra cost, maintenance and need for prefilters. It is truly a set and forget it system!
Designed for the ultimate in whole house water purification, the Whole-House-Max uses acid washed high purity granular activated carbon manufactured by steam activation from premium select coconut shell charcoal. The large surface area of our carbon makes it highly porous allowing it to treat between 600,000 to 1,000,000 gallons of water. Due to the purity of its particles, superior oxidation, and filtration capacity, the life span of the media can last up to 10Plus years when backwashed properly. This Point-of-Entry whole house filtration system will provide you and your family with an unlimited supply of clean, clear and refreshing water throughout every faucet in your home!
You can enjoy all these benefits:
APEC water systems are designed for performance, durability and reliability. We are one of the very few manufacturers who still insist on using premium components. Our durable tank, housing, and valves can withstand extreme pH and pressure changes without leaking or bursting. Our state of the art Whole-House-Max System media is NSF certified and is maintenance free for 5-8 years. The granular activated carbon is produced from premium select coconut shells using a patented process for the use in liquid phase systems - completely environmentally friendly.
For over 20 years, APEC has been the leading manufacturer of high performance water systems. Our systems are built to meet the most demanding applications in water treatment-- from drinking water for homes, to high purity water for healthcare facilities and research labs, to advanced filtration for commercial and industrial applications. Our durable water conditioning systems last for decades delivering many years of clean water enjoyment and convenience to their owners.
Our Whole House Max systems are shipped via UPS Ground in high quality double walled boxes with side cushions for extra protection. Since our systems are routinely shipped all over the world, we feel it is vital that the packaging be of top quality and no expense has been spared to ensure your system arrives safely in factory fresh condition.
To assure your highest satisfaction, please choose the right size (gpm) of the water conditioning system that at least matches your household peak demand flow rate. For example, if the most water you will use is to take a shower while doing your laundry and running the dishwasher simultaneously, then your peak demand will be (3Plus3Plus3=9) 9 gpm. This means our smallest Green Carbon water system, rated at 10 gpm, is sufficient for you.

"Looked at various units on the internet, the APEC impressed me the most. I looked at customer reviews and read very positive comments. Just installed my system July 2026, so far everything went well and system is running fine."
"Poor instructions, parts didn't match discriptions"
"We love all our APEC water products, they are very well made & customer service is amazing"
"I purchased water softener and whole house max -15 , whole house valve control board was little damaged during shipping called customer service They sent me whole new valve assembly same day Very happy with customer service also I been using under sink filtration system for over 10 years very happy with APEC product. When my old ge softener goes bad I decided this time I will purchase APEC softener and whole house It’s been over 1 month and I’m very happy with it…"
"Installation and startup went fine and the unit seems to be working properly. One issue so far was the by pass valve started leaking from the top. I used a strap wrench to tighten it and seems good for now."
"Wrong item received, trying to get ahold of APEC water systems to exchange item but their phone is disconnected."
"We tried the filters for the H2S smell in our water. the length of time they worked was very short. The filter we purchased worked from the start. we are pleased with our purchase. thank you"
"Thanks for making such a great system! My water is so much better without the chlorine and best of all the MAX 15 system can backwash and maintain itself for many years on its own without me ever having to lift a finger. The flawless stainless steel cover is also a thing of beauty and already many of my neighbors are envious. No maintenance long lasting and good looking… It’s a keeper!"
"I was initially a bit hesitant in ordering such a large and expensive system online but I am happy to now say that my shopping experience with you guys has been excellent! Your support staff was very patient with helping me determine the right whole house system and ordering the system on your website was a snap. The WTS-Max15 arrived in only 3 days and was well packed and easily installed by my plumber. Even he was impressed by the quality of the system! Thankfully my water no longer smells like bleach so I know it is working to protect me from toxic chlorine. In all I am very happy and will definitely recommend you to my friends and family."
"Just installed the new system in my house. The performance is amazing. No more chlorine no more odors. All my family love it. Great product."
