  • Effective in removing chlorine, chemicals
  • Kills microorganisms
  • Minimizes scale build up
  • Long filter life (10 years)

Well water, meanwhile, travels to your house with all the worms, germs, and viruses in it. A good filter can at best remove some of the bigger sediments and organisms, but a UV light purifier is needed to bring the water to the desired level of safety.

After the filtration process, the water will be free of most visible contaminants and will have become clear. It is now that the UV light purifier comes into effect. It kills more than 99% of viruses and bacteria, including e. Coli.

This is why this Aquasana system is the best one for well water as well as for tap water!

Best Budget Whole House Filter: DuPont WFPF13003B Universal Whole House

Certified-NSF/ANSI Standard 42 and sold at a fraction of the cost of others, it’s hard to find a system comparable to the DuPont WFHD1300B at its price range.

With a 10 micron carbon wrapped filter, the WFPF13003B can make a complete filter for the whole house by itself, especially if it’s municipal water you’re dealing with. This single cartridge would be more than sufficient to make the water clean and clear for shower, dish and clothes washing, as well as other non-digestive uses.

Install a countertop filter, or an RO system under the sink, or any other kind of water filter at the point of use for drinking water, and you should be good.

But if you want bottled water quality right at the point of entry, the WFPF13003B is compatible with many different filters with 3/4 inch inlets and outlets. You’ll have no problem adding coarser and finer PP and carbon filters before or after it for an upgrade in water purity. It goes just as well with other DuPont filters as it does with any standard filter from other brands – you gotta appreciate the versatility!

It’s cheap, AND it’s certified

The DuPont WFPF13003B comes certified with NSF/ANSI Standard 42: it effectively reduces aesthetic impurities such as chlorine and taste/odor, and of course, various sediments.

That, and the basic filter is less than $25! Even the full package (the 4-pack) is less than $200.

Frequently Asked Questions

Do I need a whole house water filter?

If you live in a fairly new building in a big city in Europe or America and you’re using tap water, you most likely don’t need a whole house water filtration system, although having one would be nice for improved water taste and smell. If you’re using well water or are living in an old house with outdated pipelines, however, you might be exposed to harmful chemicals and heavy metals. A quality system of filters at both the point of entry and point of use, in that case, would be a necessity.

Are Whole House Water Filters Worth It?

If you’re using well water: definitely yes. You will need a good filtration system that can remove sediments, rust, chemicals, heavy metals, and microorganisms to protect your health as well as household appliances. It will be worth every single penny you spend on it.

Tap water in big cities in the US, meanwhile, is pre-processed and is most of the time already safe for direct consumption. A basic whole-house filter can further remove most of the rust, sediments and some chemicals such as chlorine or chloramine, improving water smell and clarity. Unless you’re chlorine sensitive, these filters are more of a nice-to-have than an essential. In any case, most inline whole house filters are quite affordable, and can’t possibly hurt.

Can I Drink The Water Filtered With A Whole House Filtration System?

Whether or not the water; on both its original condition and the filtration materials. Note that most inline whole house filters only deal with aesthetic problems in the water (taste, smell, clearness), and very few are certified to filter out heavy metals such as lead, arsenic, and mercury. The best way to tell is to get the filtered water tested at a certified lab.

An inline whole home water filter works with your existing home water system.  These systems can turn your free tap water or well water into healthy, more pure water.  With a quality inline whole house water filtration system, contaminants are removed right before they reach your faucet.  You will not need to buy ice maker filters or shower filters, as all your water will be filtered.   These systems are easy to install and are very easy to maintain.
