APEC Water Systems

The APEC WFS-1000 is a three-stage under-sink water filter system that filters particles and pollutants from the water supply. It’s a good option if your tap water has a harsh chlorine smell or taste or if you’re worried about pesticides, VOCs, and other toxins.

The three phases of the system include a sediment filter that filters out dirt and other particles, a carbon block filter that filters out tastes, smells, and cloudiness, and a final carbon block that purifies the water even more.

The WFS-1000, unlike the APEC reverse osmosis filter, doesn’t eliminate microorganisms or lower TDS levels. Always use municipal water that has been treated. It takes up some room because it’s a three-stage system.

The WFS-1000 includes a lead-free chrome faucet. A full installation kit is included with the system. There are no extra parts or fittings required.

You also don’t have to pay a professional to install the filter. It’s made for do-it-yourself installation. The only thing that may cause difficulty is making a hole in your sink to fit the new faucet.

We adore RO systems because of their superior filtration, but the slow flow of water can be annoying at times. There is no such issue with the WFS-1000.

Because there is no RO membrane to slow down the flow, the flow rate is nearly as fast as a standard tap. You don’t even require a backup tank. Turn on the faucet to get clean, purified water.

Explore our top picks for APEC Water Systems, and don’t miss our in-depth Aqua-Pure Whole House Water Filter Reviews to find the ideal water filtration solutions for your home.

You have to change the filters once a year for upkeep. You can replace the cartridges for the filter in less than 15 minutes.

Our Verdict

This is your product if you’re looking for an under-sink water filter. The APEC WFS-1000 is the best under-sink water filter. We recommend it 10/10. It can instantly remove toxins from tap water. Unlike other filters, its flow rate is fast too. It is a good investment.


  • It is easy to install and maintain.
  • High flow rate.
  • It can purify your tap water quickly.
  • Filter lifespan is long.


  • It will not remove heavy metals.
  • It is not suitable for well water.
  • It takes up a huge space under your sink.

APEC Water Systems ROES-PH75 Reverse Osmosis System


  • Model: ROES-PH75
  • Capacity: 75 Gallons
  • Weight: 27 Pounds

 APEC Water Systems ROES-PH75

This amazing APEC ROES-PH75 is the best reverse osmosis system available. It has a 6-stage filtration system that will remove all the toxins.

  • Stage 1:  it has a 5-micron filter to trap all the sediments and dirt particles that may cause clogging.
  • Stage 2 & 3: It comprises a coconut-based activated carbon black filter that absorbs chlorine, VOCs, and other dangerous toxins. It also eliminates foul taste and odor.
  • Stage 4: it has a semi-permeable thin-film compound RO membrane that will remove remaining contaminants and heavy metals.
  • Stage 5: it has a granular carbon filter that helps in removing odor and foul taste.
  • Stage 6: it has a calcite filter that adds calcium carbonate to water and increases the alkalinity.

It can easily purify 75 gallons per day. Its flow rate is good. It is WQA certified. It comes with a two-year warranty by the brand.

The system includes a 100% lead-free design faucet and JG Food-safe piping and parts to offer safe, contamination-free pure water. Unlike other brands, high-quality leak-free connector fittings will not require additional locking clips to plug leaks and do not rely on leak detection to protect your home.

Our Verdict

The APEC ROES-PH75 is the best reverse osmosis filter. It has 6 stage filter system that will remove every containment and sediment from the water. It also removes bad odor and taste. We’ve tested it ourselves, and we like this filter. We highly recommend this filter.


  • It can treat well and tap water.
  • It has a good flow rate.
  • It has a remineralization system.
  • It has a 6 stages filtration system.
  • It is affordable.


  • It is not NSF certified.
  • It might leak.

APEC Water Systems WH-SOLUTION-MAX15 Whole House Water Filter


  • Model: MAX15
  • Filter Capacity: 10 Years
  • Warranty: 10 Years


The APEC MAX15 is a whole-house water softener and filter in one. Compared to regular activated carbon, catalytic granular activated carbon is a far more advanced filtration media.

It eliminates chlorine and chloramine from water and the taste or odor associated with them. In addition, it removes VOCs and other possibly harmful contaminants from tap water.

This carbon filter does not need to be updated every few months like conventional carbon filters. It has a ten-year lifetime. An electrical valve head monitors water flow and starts a backwash to clear trapped impurities to maximize filtration performance.

The water softener comes in second place. The MAX15 does not utilize salt to reduce hardness particles from your water, unlike standard water softeners.

It’s a non-salt water softener. There will be no difference in water hardness before and after filtration. This is because the system neither removes nor increases the hardness of minerals in the water.

Instead, it utilizes ceramic media to adjust hard water’s function so that it does not build scale on the surface. This saves your appliances and pipes, makes water washing easier, and enhances the purity of your shower water.

This is a whole-house water system; it takes longer to install than an under-sink filter. To install it, APEC suggests that you have some basic plumbing knowledge. The APEC MAX15 is suited for large households with three to six bathrooms.

Don’t miss our in-depth Whirlpool Reverse Osmosis Reviews for even more water purification options.

Our Verdict 

We highly recommend this APEC MAX15. It is best for large families. It can quickly purify water; the best part about this filter is that it offers 10 years lifespan. You’ll not regret buying this.


  • It’ll stop scale buildup.
  • 10 years filter life.
  • It removes dangerous contaminants.
  • It enhances water quality and taste.


  • It is expensive.
  • Installation takes time.

APEC Water Systems RO-CTOP Portable Countertop Reverse Osmosis Water Filter System


  • Model: RO-CTOP
  • Weight: 7 Pounds
  • Capacity: 90 Gallons

APEC Water Systems RO-CTOP-C Portable

The APEC RO-CTOP-Countertop RO system is designed for people who don’t want or cannot set up a complete under-sink RO filtration system.

The APEC RO-CTOP-C is ideal if you only need a portable filter, you live in an apartment or dorm where you can’t interfere with the piping, or you may not have enough area beneath your sink.

It’s a four-stage RO system that perfectly fits on your kitchen counter. It’s tiny (and lightweight) enough to take with you and use in hostel rooms, RVs, boats, or a mate’s house. It, like other countertop water filters, connects straight to your faucet. It installs in just five min and fits most basic faucets.

The filter configuration of the RO-CTOP-C is nearly identical to that of full-size systems. The key distinction is that it only has one carbon pre-filter rather than two.

On the other hand, the sediment and activated carbon pre-filters do an excellent job of removing particles, chlorine, and other pollutants before they block or ruin the membrane. The third and fourth steps are the RO membrane and a post-filter.

The RO-CTOP-C lacks a reserve tank, another major difference from larger systems. Water is cleaned immediately when you open the lever on the faucet adapter. The flow rate is fairly low, which is a major disadvantage. A slow stream of water emerges.

Users suggest refilling a water pitcher or bottle beforehand for easy access to safe drinking water. In general, the RO-CTOP-C is a useful alternative for individuals who cannot install an under-sink system. However, given the size and rate of flow, it is a little costly.

Check out our Aquasana AQ-4000 Reviews to explore another excellent choice for clean and refreshing water.

Our Verdict

It is the best portable filter for people living in a rented house or an RV who cannot fix it under the sink. We recommend RO-CTOP as it is compact, easy to install, and can easily purify your water.


  • It is portable.
  • You can easily install it.
  • It is the best choice for anyone who cannot install an under-sink filter.
  • Top-notched filter performance.


  • The slow rate of flow.
  • It doesn’t have any mineral filter.

APEC Water Systems CT-2000 Countertop Water Filter System


  • Model: CT-2000
  • Capacity: 1000 Gallons
  • Weight: 4.72 Pounds

APEC Water Systems CT-2000

A countertop water filter is an excellent option if you can’t put an under-sink system. It’s also a good choice if you want something less expensive or don’t want to go with the trouble of putting in an under-sink water filter.

The APEC CT-2000 is the finest APEC countertop water filter. It’s a little space-saving filter that rests on your countertop and attaches straight to the faucet. You connect the faucet to a diverter valve. Water is sent from the faucet to the filter via a tube. The filter features a built-in faucet that delivers purified water. The CT-2000 from APEC is a four-in-one filter. Four types of filters are contained within the plastic container.

The first one is a ceramic filter that removes cysts, germs, and silt from the water. The ceramic filter has a silver ion medium that inhibits bacteria development and helps the filter self-sterilizing.

An activated carbon block removes chlorine and any unpleasant tastes and smells from the water. It also minimizes pollutants like insecticides and VOCs. Lastly, an ion exchange resin decreases lead and other heavy metals.

The filter has a reasonable lifespan and should be replaced once a year. That’s great because the replacement filter isn’t inexpensive. The APEC CT-2000 has a yearly maintenance cost of around $80.

However, given that this is a 4-in-1 filter rather than a conventional carbon filter, the price is justified. It removes much more pollutants than conventional countertop systems’ filters.
Our Verdict
We think this is the best option for you if you want a countertop filter. This APEC CT-2000 is economical, efficient, and easy to set up. It can easily remove all impurities and toxins with a five-stage filtration process.


  • It is small.
  • 4-in-1 filter that can remove all impurities.
  • It is easy to install.


  • Expensive replacement filters.
  • It can only treat municipal water.

Buying Guide

We hope that this buying guide will help you pick the APEC Water Filter.

Filtration Stages

An APEC system’s number and kind of filtration stages determine how successfully it purifies water and what it screens out.

Compared to a 5-stage system, a 7-stage system will be more effective. Also, look at the kind of filters that are utilized. Compared to a system with ordinary activated carbon, a system with a catalytic carbon filter will perform better, taking out chloramines and chlorine.

If you will utilize well water, go for a system with particular filters to remove iron, hydrogen sulphide, and other typical toxins in well water.

Look for a filter with reverse osmosis membranes or a UV sanitizer if you’re concerned about pathogens in the water.


See the kind of upkeep the water system needs.

Check how many water filters need to be replaced and how long you should replace each one. Remember to check up on the cost of replacement filters; this will benefit you in calculating the system’s maintenance fees.

Check how frequently you have to add salt to water softeners. Check for other consumables that need to be replaced regularly, in contrast to salt and filters.

Filter Capacity

Before placing an order, double-check the GPD of the system. GPD stands for gallons per day, which refers to the amount of purified water a system can generate daily.

The more people in your family, the more GPD you’ll require. Calculate how much pure water you’ll need daily to determine the proper capacity. A complete house system will cost significantly more than an under-sink system (most have a 50-100 GPD capacity).

 System Type

The first step is to determine what type of water system you require. Your requirements will determine this. Here’s a rundown of what each filter is useful for.

  1. Under-sink water filter: Filters chlorine, chloramines, sediment, and pollutants from city water. Some under-sink water treatment devices are made to work with well water.
  2. Under-sink RO system: Filtering chlorine, chloramines, silt, chemicals, heavy metals, and microorganisms from municipal or well water with an under-sink RO system. If you’re worried about heavy metals or microorganisms in your drinking water, invest in a RO system.
  3. Whole-house water filter: This is the best option if you want to filter all of the water entering your home. The majority of whole-house filters can remove chlorine, pollutants, and sediment from municipal water. If you use well water, consider a water filter that can eliminate toxins like iron found in groundwater.
  4. Whole house water softener: If you reside in a hard water location, a whole-house water softener is a good option. A whole-house water softener lowers the hardness of all water entering the home. Some systems do not require salt. They adjust the behavior of hardness minerals to minimize scale rather than adding salt to the water to soften it.
