How to Compare Doulton to Berkey Water Filters

A wide variety of water filters is available to consumers, and a number of different companies sell water filters. Each company should be carefully researched before you decide which one offers the right water filter choice for your home. If you've managed to narrow your choice down to either a Doulton or Berkey water filter, then you can now focus on comparing the options of those two companies. With a little research, you can find the ideal water filter for your needs.

Skill level:


  1. 1

    Find the type of water filter that's best for you home. If you only need the water filtered from your kitchen sink, then a countertop or under-sink filter should be plenty. However, if you would like the water from all of your fixtures to be purified, then you need a whole house system. Berkey only offers portable, countertop water filters, so under-sink and whole house systems will not be available. Doulton offers all types of filters. Generally, Doulton's countertop water filters are best for everyday use, while Berkey's are best for emergencies and family outings because they're designed to take on the go.

  2. 2

    Make a budget. Knowing what you can afford to spend will help you narrow down your choices considerably and choose a brand. For example, as of 2010 countertop filters by Berkey range from about £130 to £390, while Doulton's are all around £130 or £195.

  3. 3

    Pay attention to the cost of replacement filters, as well as how often you need to replace them and how many filters come with your initial purchase. All of these factors will contribute to the annual operating cost of your water filter. For example, Berkey's Crown Berkey purifier system can cost almost £390; however, this price includes eight replacement filters. These replacement filters will significantly lower the cost of operation for a year or two, depending on how much you use your system.

  4. 4

    Look for a water filter that has the capacity you need for your household. If a system is less expensive but not large enough to get the job done, then it's going to be much more difficult to get your water filtered by the system at the rate you need. Doulton's largest model of countertop filters holds up to 18 gallons and filters up to 1 gallon per hour, while Berkey's countertop filters hold less at a time, usually around 3 or 4 gallons, but can filter up to 8 gallons per hour. Which you choose depends largely on what you'll be using the water filter for.
