APEC vs iSpring Reverse Osmosis

APEC Water Systems Brand Overview

APEC (Advanced Purification Engineering Corp) is the leading manufacturer of residential RO systems in the US. They are based in California, where they design and assemble their products.

The company has been in the water industry for over 20 years and boasts an unbeatable reputation for producing the highest quality RO systems.

iSpring Water Systems Brand Overview

Ispring is a family-owned company based in Atlanta that produces different types of water filters for a variety of residential and commercial needs.

The company’s mission is to ensure that clean drinking water is accessible and affordable to everyone.

Their RO systems use a multi-stage system that removes almost every contaminant from water. The filters are great for both well and tap water.

APEC vs. iSpring: Similarities

  • Contaminants Removed

Reverse osmosis systems from both APEC and iSpring are designed to remove heavy metals and 1000+ contaminants from your drinking water.

They boast an RO membrane with 0.0001 ultra-fine pores that filter all impurities except microorganisms like viruses and bacteria.

  • Premium Quality

The quality of the components of a reverse osmosis system significantly affects the unit’s reliability, efficiency, and effectiveness.

Get a system made from low-quality components, and you will always have to deal with constant malfunctions. Your water may also not be filtered to perfection.

APEC and iSpring water filtration systems are made from high-quality components that last for a long time with proper maintenance.

  • Easy Installation

Although most RO systems are believed to be hard to install, this isn’t the case with models from APEC and iSpring.

Both manufacturers claim that you can install any of their units with excellent DIY skills without the help of a professional.

In fact, there are online videos and instruction manuals that come in handy during the installation process.

  • Leak-Free Fittings

Water leaks are wasteful and annoying. If you’ve experienced water leaks, you know that they can damage furniture, tiles, and home equipment that can be expensive to repair.

Manufacturers of APEC and iSpring RO systems claim that you do not have to worry about their products. Their RO systems come with leak-free fittings that guarantee zero water wastage.

APEC vs. iSpring: Differences

  • Capacity

Reverse osmosis systems can produce a lot of water in a day. Most iSpring models produce a minimum of 75 gallons of clean and pure water per day. This water is enough for a medium-sized family.

APEC RO systems have varying capacities as well. The system with the lowest water production rate, like the APEC ROES-50 (Amazon#Ad), filters 50 gallons of water per day.

  • Filters

All reverse osmosis systems use filters, which help to purify the water. Before paying for an RO system, always inquire about the filter life and the cost of replacement filters.

APEC systems feature long-lasting filters with a filter life of 1 year hence better than iSpring models, which usually require filter replacements twice a year.

  • Housing

APEC and iSpring models have different housing designs. While APEC features a non-transparent material, iSpring models have a transparent 1st stage housing.

The transparent housing lets you inspect the pre-filter and visually see the contaminants getting removed. This allows you to know when it’s time to change the filter.

  • Warranty

When buying any device for your home, always check the warranty period. The longer it is, the better – it shows that the manufacturer is confident with the quality of their product.

APEC water warrants their customers that their residential RO systems will be free from defects in workmanship and material under normal use for 1 year from purchase.

iSpring, on the other hand, offers a 1-year original manufacturer’s limited warranty. You can choose to prolong the system’s protection by purchasing a 3-year extended warranty. Just ensure that you pay for it before the original warranty expires.


APEC and iSpring are both great brands that make high-quality reverse osmosis systems. Whichever brand you choose to get your water purification system from, you’ll absolutely get the best with minimal search.

In this comparison, we’ve included a comprehensive list of features that we hope will help you choose the best brand for your home with ease.

After settling on the brand, the next step should be searching for the best reverse osmosis system from the brand in question.
