Numerous Filters to Choose From

You can choose to buy a sediment or carbon filter as a standalone whole home filter, or combine several of APEC’s heavy-duty water filters to target a broader range of contaminants at once.

Large, Fast-Flow Filters

Regardless of which Big Blue filter or filter set you choose, the filters are all 20 inches in size, with 1-inch inlet and outlet ports and 1.25-inch internal ports. That means no reduction in flow rate for you.

Various Micron Ratings Available

Different Big Blue filters have different micron ratings depending on the contaminants they’re designed to target. The maximum micron rating is 30, for the Big Blue sediment filter, which is designed to remove large particles of sand, silt, rust, and dust.

1-Year Warranty

Most APEC filters are backed by a 1-year warranty that can be extended to 2 years if you register the system online.

🚦 Performance

We measure the performance of all filters we test by assessing three factors:

  • The contaminants removed, or the effectiveness of filtration
  • The filter flow rate, or the speed of filtration
  • The filter lifespan, or the longevity of filtration

Let’s start by looking at contaminants removed. The different Big Blue filter options all target different sets of contaminants:

FilterContaminants Reduced
CB1-SED20-BB 30-micron sediment filterSand, dirt, silt, rust, and scale down to 30 microns in size.
CB1-CAB20-BB 25-micron carbon filterChlorine, taste and odor, and some volatile organic compounds (VOCs) down to 25 microns in size.
CB2-SED-CAB20-BB sediment and carbon filter comboSediment, dirt, rust, chlorine, and some VOCs to 25-30 inches in size.
CB3-SED-KDF-CAB20-BB sediment, KDF and carbon filter comboSediment, dirt, rust, chlorine, and some VOCs, heavy metals and hydrogen sulfide.
CB3-SED-IRON-CAB20-BB sediment, iron, and carbon filter comboSediment, dirt, rust, chlorine, and some VOCs, rust, orange staining, and metallic taste and smell.
CB3-SED-CAB-CBC20-BB sediment, GAC carbon and carbon block filter comboMore thorough chlorine and chemical reduction than the sediment and single carbon filter set.

In all, we think that all these filter options serve a purpose. Don’t expect to be overwhelmed by the contaminants removed by any of the Big Blue filters, but if you just need a simple solution to improve your water’s taste or get rid of sediment, you have plenty of good options.

APEC mentions NSF certifications on its website, but there isn’t any clear information about performance certifications. It looks like some of the filters just use NSF-certified components, which is a start – but we’d prefer the reassurance of NSF-certified performance.

As for flow rate, APEC doesn’t specify a maximum flow rate for any Big Blue filters. What we do know is that the filters all have 1-inch inlet and outlet ports and 1.25-inch internal ports that prevent a significant pressure drop. APEC says you should experience less than a 1 GPM drop in water pressure after installing one of the Big Blue filters. So you shouldn’t notice any change to your water flow, even during peak demand.

Finally, filter lifespan. The Big Blue filters last around 70,000-80,000 gallons (or 1 year), which is pretty average for a whole house water filtration system. The sediment filter can be washed and reused, too, further extending its lifespan. Check the specific product details for the filter you’re interested in for its actual lifespan.

πŸ“Œ In all, we think in terms of performance, the APEC Big Blue water filters are good, but not exceptional. We’ve seen better contaminant removal from other water filtration systems, but the flow rates and filter lifespans for the BB filters are good.

πŸ”§ Installation & Maintenance

As with any whole-house water filtration system, the APEC BB filters will need to be installed at your main water line, upstream of your water heater. That means cutting into your plumbing, which not everyone is comfortable doing.

That said, we think you can easily install any of these filters yourself, as long as you follow the installation instructions in the user manual carefully.

Included with the filter system are:

  • User manual
  • Filter housing(s)
  • Filter cartridge(s)
  • Pressure relief valve
  • Filter wrench

Make sure to shut off your water supply and drain the remaining water from your pipes by opening your faucets before you get started.

You’ll need to buy your own fittings and tubings to connect the filters to your plumbing. Flex tubing is best since it’s easiest to cut and manipulate to size.

We also recommend spending extra on a bypass valve, allowing you to divert water around the system during maintenance or troubleshooting.

Maintenance is easy, too – just replace the filters as advised in the user manual, or when your flow rate drops significantly. The sediment filter can be cleaned with normal tap water and reused.

πŸ“ Filter Info

There are several different filters available in the Big Blue series:

  • The 30-micron sediment filter: removes large sediment particles by trapping them in the filter media; best for well water
  • The GAC carbon filter: uses adsorption to trap chlorine, some VOCs, and other chemicals; best for chlorinated municipal water
  • The carbon block filter: compact carbon media provides more thorough adsorption and chlorine removal
  • The KDF filter: reduces lead and hydrogen sulfide; good for city water and well water
  • Iron filter: reduces rust, metallic taste and smell, and orange stains

Carbon, KDF, and sediment filtration are all popular filter choices for whole house systems with plenty of research to support their efficacy in long-term water treatment. We like that APEC also offers an iron filter cartridge, too, although this will only be good for ferric iron, not dissolved iron (which will need to be oxidized first).

πŸ”” Pros & Cons

πŸ‘ What We Like

  • We love that you can mix and match different filters depending on the most prevalent contaminants in your water supply.
  • The filter sets come pre-assembled in their own filter housings and are ready to install with the included wall mount, making for super convenient installation.
  • No matter which Big Blue filter or filter combo you opt for, you won’t ever pay more than $500. That’s fantastic value.
  • The plastic construction helps keep costs down, but the material is sturdy and built to last, with durable heavy-duty metal brackets for installation.

πŸ‘Ž What We Don’t Like

  • Although these APEC filters target a lot of the most common contaminants in water, they only cover the basics. Don’t expect anything really special from these filters.
  • There are no test results for us to look at, and the filters don’t appear to be NSF certified. That means we just have to trust APEC’s word that the filters remove what they’re advertised to remove.
  • We think it’s a bit annoying that there isn’t a built-in bypass valve included with any of these water filtration systems, so you’ll need to buy your own.
