Compare Whole House Water Filters
Home Water Filtration System Comparison & Ratings
People often ask me to compare whole house water filters and I tell them I am reluctant to do so. The reason is that direct comparisons are tough and some statements are intended to be misleading. In the chart provided below I provide a comparison of whole house water filtration systems be selecting four relatively well known competitors and listing selected criteria.
On this page I provide a comparison of whole house water filtration systems to my Urban Defender whole house water filter. This home water filtration system comparison lists two well known backwashing systems, one well known cheap alternative, and the most costly filter on the market.
Note: these numbers are aging due to Covid and supply chain issues but all companies are subject to the same pressures. Once that stabilizes I’ll update it (3-25-22)

*** This is a well known upflow system. I’ve removed the name on my own. As you can see it is the cheapest to buy. It is also the least effective. Learn more here.(1) prices may vary from those listed above. Price increases due to covid will affect this chart but the idea is the same.
(2) The problem with estimating gallon capacity is that water quality will vary in every city and how long a system will last depends entirely on the level of chlorine in the water along with the levels of other contaminants.
The amount of KDF and carbon and other media or the type of carbon used are also factors. In this comparison I am using 2 mg/l of chloramine in city water and catalytic carbon as the media to derive the numbers provided.
What is misleading about the NSF 42 certified systems is that they have been tested to the gallons listed but only have to remove 50% of the chlorine or chloramine to gain certification. Real life residential application will not result in the volumes they claim. My estimate is an attempt at a real number.
(3) I assume a 12 year life with one media change at 6 years. The Urban Defender could easily be used again and that would lower the cost further. Big company claims a 16 – 20 year life. This is a false claim. Since both systems use similar media one would have to evaluate the contaminant levels upon which big company bases this claim. Another well known product sold through plumbing companies claims a 3,000,000 gallon life. This is simply false. It may remove chlorine for that long but the dangerous trihalomethanes and haloacetic acids will not be removed after 500,000 gallons. That company actually uses carbon that is less effective than what I use. Ultimately you have to decide who to trust and who knows what they’re talking about.
(4) The Urban Defender whole house water filter uses NSF certified media. Big company is certified for NSF 42 Aesthetic Effects, which basically means that it removes some chlorine. Big company’s removal claim for gallons is for half of the chlorine or chloramine in your water.
(5) Systems that do not backflush are subject to decreased effectiveness in a short time. I have considered manufacturing such a system but can’t bring myself to do so. Ask me why backwash carbon systems are more effective than upflow systems.
(6) As I stated above, how long the media within a system will last depends on the level of contaminants as well as the amount of water used. In this case I assume a 10 year life for the purpose of comparison.
All performance claims and pricing are based on the Manufacturer’s or Authorized Distributor’s literature.
These whole house water filtration system comparisons illustrate that the Urban Defender is affordable and the most cost effective backwashing whole house water filter on the market.
As I note at the top of this page it is a challenge to compare whole house water filters because there are subtle differences between the various models. I have attempted to provide this information for those who find it useful.
The Urban Defender is equal to or more effective than the more expensive water filtration systems listed above. You have my word on that.

Dear Jim, you make me realize in a special way how our happiness depends on direct human relationships, with nothing standing in the way between full and honest communication of what knowledge each of us has. Bless your enterprise.

Freeport, MaineI decided to purchase the Urban Defender for whole-house filtering and a reverse osmosis unit for drinking water (I live in Los Angeles).
It is hard to explain the sense of satisfaction and safety I feel knowing that the water I bathe in and drink is healthy.

Los AngelesI couldn’t stand the smell of cooking odors in my home. Now, within 15 minutes of cooking, the odors are gone. Also, I have always had allergies. They’re not bothering me anymore either. I love this machine. It works. It’s worth every penny. I like it so much…..

Los AngelesThe iron system is fine; our water is clean and the toilets aren’t stained. My bride is happy! As a matter of fact, the system seems to have had a softening effect on our water – a fringe benefit we hadn’t expected but are happy to have.
